Aluminium granules are small, free-flowing particles of aluminium or aluminium alloy, usually between 0.05 mm and 10 mm in size, made by melting aluminium and breaking the molten stream into droplets that solidify into discrete particles. They are consumed as a deoxidising agent in secondary steelmaking, as a gas-forming agent in autoclaved aerated concrete, as remelt and alloying feed in foundries and die casters, as feedstock for aluminium paste and pigments, and in chemical applications including water treatment and aluminium salts.
This guide concentrates on the route an Indian promoter can realistically build today: a scrap-fed secondary melting plant of roughly 2,400 to 6,000 tonnes a year that sorts and melts aluminium scrap, refines the melt, produces granules by water granulation or melt atomisation, and then dries, screens, classifies and packs them into the size bands buyers specify. The focus falls on deoxidation, AAC gas-forming, foundry and atomised grades, because these are the volumes Indian steel producers, block plants and foundries buy on repeat contract, and because they can be produced from one melting line with a properly equipped screening and laboratory section.
This guide is written for investors trying to understand how to start an Aluminium Granules manufacturing plant in India: the process, machinery, raw materials, location, cost, profitability, licenses and the role of a project report and DPR.

| Typical Payback Period | 3 to 5 Years |
The snapshot above sets out the size, growth, supply position and investment frame for the sector, at a scale an Indian promoter can act on. All figures are indicative estimates drawn from general industry knowledge and are meant for early planning only.
The snapshot describes a market that grows steadily rather than spectacularly, and whose economics are governed by metal cost rather than by product novelty. Demand comes from industrial buyers rather than from consumer spending, so volumes are repeatable and contracts are annual. The commercially interesting part is the supply gap in fine and atomised grades, which is filled largely by imports: a plant that can hold particle-size distribution and chemistry inside tight limits can displace imported material while still earning a normal secondary-metals margin. The wide investment range reflects the genuine choice between a single-furnace unit serving regional foundries and a two-line plant with atomisation, classification and packing capability aimed at steel and AAC customers. The sections that follow work through that choice.

The opportunity rests on a structural feature of the Indian metal market: a large and still-growing industrial demand for aluminium as a deoxidiser and gas-forming agent, set against a supply base that is fragmented at the fine end and import-dependent at the atomised end. A granule plant is a conversion business, not a mining or smelting business, so capital intensity is modest relative to revenue, the technology is well understood, and the plant can be built in twelve to eighteen months. The parameters below give an indicative frame.
These ranges are indicative and frame early feasibility work only. Actual returns depend chiefly on the landed cost of aluminium scrap, the size-grade mix actually sold, and the share of output committed to annual contracts rather than spot sales. A site-specific Aluminium Granules Feasibility Report narrows each figure to your capacity, feedstock and customer mix.
Table of Contents
Aluminium granules manufacturing is the conversion of aluminium scrap and ingot into discrete, graded particles of controlled size and chemistry. A plant melts sorted scrap in a crucible, reverberatory or induction furnace, adjusts the chemistry to the grade being produced, removes dross and dissolved hydrogen, and then breaks the molten stream into droplets that solidify either in a water bath or in a gas atomising chamber. The solidified particles are dewatered, dried, screened into size bands, de-dusted and packed. The activity sits at the refining end of the secondary aluminium chain: rather than casting ingots that a foundry must remelt, the plant sells a graded material that a steel shop, an AAC block line or a chemical reactor can feed straight into its own process.
Commercially, this is a conversion business rather than a materials business. Value is added by narrowing the specification, covering aluminium content, particle-size distribution, moisture, dross content and flowability, and by repeating that specification batch after batch and month after month. Steelmakers, block plants and foundries qualify a supplier on trial lots and then buy on annual contracts, so the first order is difficult to win and the tenth is straightforward. That is why the laboratory, the screening and classification section, and the batch records behind them carry as much weight in the business case as the melting furnace itself.
The manufacturing scope of a typical Indian plant therefore runs wider than the furnace. It includes scrap procurement and sorting, melting and refining, granulation or atomisation, drying, multi-stage screening, air classification, de-dusting, emission control and packing, supported by laboratory testing, weighbridge operations and a scrap yard that keeps alloy families physically separated. The size of the melting and granulation section, and the number of saleable size bands graded, are what separate a small unit supplying nearby foundries from a plant serving steel and AAC customers on contract.
The Main Aluminium Granule Product Types
This guide prioritises the deoxidation, AAC gas-forming and foundry grades, because together they account for the bulk of Indian consumption and can be produced from a single scrap-fed line with drying, screening and classification capability. Atomised and chemical grades are treated as an extension of the same plant, since they demand a tighter process window, a finer size band and a more capable laboratory, and are normally added once the base grades have won repeat industrial buyers.
| Aluminium Granule Type | Description | Key Property | Primary Demand |
|---|---|---|---|
| Deoxidation Granules (2 mm to 8 mm) | Coarse particles formed from a refined melt for steel deoxidation | Aluminium content above 97%, low moisture, low fines | Secondary steelmaking, induction furnace steel shops |
| AAC Gas-Forming Grades (0.05 mm to 0.5 mm) | Fine granules that react with alkali in the slurry to release hydrogen | Tight size band and predictable reactivity | Autoclaved aerated concrete block plants |
| Foundry and Alloying Granules (1 mm to 10 mm) | Remelt feed and alloying addition for casting shops | Consistent chemistry and low iron pickup | Foundries, die casters, alloy makers |
| Atomised Granules (0.3 mm to 1.5 mm) | Gas or air atomised particles with a narrow size distribution | Rounded shape and uniform size band | Aluminium paste, pigments, chemical intermediates |
| Chemical and Catalyst Grades (0.1 mm to 1 mm) | Feedstock for aluminium salts, catalysts and treatment chemicals | High reactivity and low heavy-metal content | Aluminium sulphate, water treatment, catalysts |
Key Growth Drivers in the India Market
India-Specific Market Opportunity
| Segment | India Market Context | Manufacturing Role |
|---|---|---|
| Steel deoxidation | Induction and electric furnace steel capacity expanding across the eastern and western belts | Coarse granule grades supplied in bulk bags on annual contracts |
| AAC block production | Rapid growth of AAC capacity near metro construction demand | Fine, tightly graded gas-forming granules meeting reactivity specifications |
| Foundry and die casting | Established foundry clusters in Coimbatore, Kolhapur, Rajkot and Belagavi | Foundry feed and alloying granules with certified chemistry |
| Chemical and water treatment | Rising demand for aluminium salts and treatment chemicals | Reactive fine grades produced to chemical specification |
| Aluminium paste and pigments | Atomised feedstock still substantially imported | Locally atomised granules displacing imported material |
The strongest opportunity for a new entrant lies at the intersection of a regional scrap pool and a regional buyer base: a plant that can buy sorted scrap within a short radius and sell graded granules to steel, AAC and foundry customers within the same radius carries the lowest freight and the highest repeat business.
The Aluminium Granules Manufacturing Process rests on one controlling idea deliver clean, correctly alloyed liquid metal to the point of droplet formation at the right temperature and pour rate, then freeze each droplet fast enough to set a usable particle. Everything upstream of granulation protects chemistry; everything downstream protects size distribution, moisture and cleanliness. The sequence below describes a scrap-fed plant producing coarse through fine saleable grades.
The Aluminium Granules Manufacturing Process Flow
Three points in this flow decide both quality and cost. The first is melt chemistry before granulation, because a batch outside specification produces an entire lot of granules that cannot be sold into the intended grade, which makes goods-in sorting and furnace-side spectrometry essential rather than optional. The second is granulation temperature and pour rate, which together set the particle-size distribution and the fines yield; producing too much material below the smallest saleable band converts saleable metal into recyclable dust. The third is drying and de-dusting, because residual moisture and entrained dust cause handling and feeding problems at the customer's plant. A producer that tests size distribution and chemistry on every batch, and records both against the despatch, can hold its price in a market where most competitors cannot.
| Unit Operation | Key Activity |
|---|---|
| Raw material receipt and sorting | Weigh incoming scrap, check for radioactivity, segregate by alloy family, remove non-aluminium attachments |
| Scrap preparation and cleaning | Shred or shear oversize scrap, remove oil, paint and coatings, magnetically separate iron, dry wet material |
| Charge make-up and weighing | Weigh the furnace charge to a target chemistry and add alloying and hardener additions |
| Melting | Melt the charge at 660 to 780 degrees Celsius in a crucible or induction furnace under a protective flux cover |
| Refining and degassing | Remove magnesium and other impurities where required, inject flux or inert gas to strip hydrogen, skim dross |
| Melt holding and transfer | Hold at the atomisation temperature, filter through a ceramic or mesh filter, control superheat in the launder |
| Granulation or atomisation | Pour through a perforated plate into a water bath, or break the stream with a gas jet inside an atomising chamber |
| Quenching and solidification | Solidify the droplets in a controlled water quench with regulated temperature and flow |
| Dewatering and drying | Centrifuge or screen the wet granule slurry, then dry in a rotary or fluid-bed dryer to the specified moisture |
| Screening, classification and packing | Grade granules into size bands on multi-deck screens, air-classify and de-dust fines, test, weigh and pack |
The raw material list for an aluminium granules plant is short, and one item dominates it. Aluminium scrap is both the largest input by value and the input whose quality most directly decides whether the plant can hold a specification at all, because chemistry that enters through a mixed or contaminated charge cannot be corrected economically after melting.
Because scrap can be 70 per cent or more of operating cost, sourcing strategy is the single largest lever on both margin and quality. A plant that keeps alloy families separated at goods-in, buys from a small panel of dependable traders and a few direct industrial generators, and holds thirty to forty five days of cover can ride out short-term market tightness. Documentation matters as much as metal: imported non-ferrous scrap must carry a pre-shipment inspection certificate from an agency recognised by the Directorate General of Foreign Trade, and scrap handling falls under the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016, so the paperwork must be in order before the first import consignment lands. The residual risk is price, because aluminium scrap tracks primary metal and the London Metal Exchange while sales contracts are often fixed; contracts that pass the movement through, or that are repriced quarterly, protect the conversion margin that the plant actually earns.
| Raw Material | Role in Process | India Sourcing | % of OpEx |
|---|---|---|---|
| Aluminium scrap (runners, risers, turnings, extrusions, old sheet) | Primary melt charge supplying the metal content of the granules | Scrap traders in Gujarat, Maharashtra, Tamil Nadu and the NCR; imports through Mundra and Kandla | 66% to 74% |
| Aluminium ingot and hardener alloys | Chemistry correction to bring a batch to the target grade | Domestic smelters and alloy makers across the eastern and western belts | 5% to 9% |
| Melting and degassing fluxes | Protect the melt, assist dross separation, strip dissolved hydrogen | Indian flux manufacturers; largely available indigenously | 2% to 4% |
| Crucibles, refractories and nozzles | Contain and shape the molten metal stream through granulation | Gujarat and Maharashtra refractory and graphite suppliers; some nozzles imported | 2% to 4% |
| Packaging (HDPE woven bags, liners, jumbo bags) | Protect granules from moisture and contamination in transit | Pan-India polymer packaging suppliers | 2% to 3% |
| Treatment chemicals, lubricants and water | Cooling water treatment, equipment maintenance and dust suppression | Local industrial suppliers | 1% to 2% |
Site selection for an aluminium granules plant is decided by three requirements that must be satisfied together: access to metal feedstock at a competitive landed cost, uninterrupted power at an industrial tariff, and freight proximity to the steel, construction and coatings customers who buy the output. Because the product is dense and comparatively low-value per tonne in its coarse grades, transport cost is a material share of the delivered price, and plants located far from both feedstock and market cannot compete on landed cost.
Choosing the Best Location for Aluminium Granules Manufacturing Plant Setup
The best location for Aluminium Granules manufacturing plant setup is almost always decided by two distances: the distance to a reliable scrap pool and the distance to industrial buyers of graded granules. Metal is heavy and low in value per tonne relative to freight, so freight on both the inbound and outbound leg eats directly into a conversion margin that is itself only in the low double digits. Power and furnace fuel availability, an industrial land parcel already zoned for a secondary metal unit, and access to a state pollution control board that understands non-ferrous melting matter next. The states below combine these factors to different degrees, and the right answer for a given investor depends on which customer contract is in hand.
| State | Why It Works | Key Advantage |
|---|---|---|
| Gujarat | India's largest non-ferrous scrap trading and secondary remelt cluster, with Mundra and Kandla for imported scrap | Deep feedstock market and competitive scrap pricing |
| Chhattisgarh | Sits inside the Korba-Raipur metal belt with smelter capacity and strong induction furnace steel demand | Molten metal expertise, alloy availability and nearby steel buyers |
| Odisha | Aluminium smelting and downstream cluster around Angul and Jharsuguda, with Paradip port access | Proximity to primary metal, alloy makers and eastern steel plants |
| Maharashtra | Foundry and engineering clusters at Kolhapur, Pune and Nashik with an established scrap trade | Ready demand from foundries and die casters |
| Tamil Nadu | Coimbatore and Hosur foundry and auto component clusters with port access at Chennai and Tuticorin | High-value alloying and foundry grade demand |
| Haryana-Rajasthan NCR belt | Large AAC block and auto component demand with strong logistics into northern and central India | Close to AAC and construction material customers |
Location selection for a secondary aluminium or alloy plant turns on scrap feedstock access, smelting infrastructure, and buyer proximity. Gujarat leads on feedstock economics through its non-ferrous scrap cluster and port-linked imports, while Chhattisgarh and Odisha suit operations tied to primary metal belts. Maharashtra’s foundry clusters generate ready die-casting demand, Tamil Nadu serves high-value auto and foundry buyers, and the Haryana-Rajasthan NCR belt is the natural fit for plants supplying AAC block and construction material customers across northern India.
Cleanliness, Process Control and Quality Standards
Quality in this business is measured, not assumed. A granule plant supplying steel, AAC and foundry customers should operate a quality management system to ISO 9001:2015, an environmental management system to ISO 14001:2015 and an occupational health and safety system to ISO 45001:2018, because large industrial buyers increasingly audit suppliers against these frameworks before awarding annual contracts. The in-house laboratory should work to the discipline of ISO/IEC 17025 even if formal accreditation is deferred, and should record every batch result against the despatch reference so that a customer complaint can be traced to a specific melt.
The specific tests that matter are chemistry and particle size. Melt and product chemistry is normally verified by spark atomic emission spectrometry, with the test practice aligned to ASTM E1251, while particle-size distribution is established by sieve analysis following ASTM B214 using test sieves conforming to ISO 3310-1, and apparent density is measured following ASTM B212 for grades sold on a volumetric basis. Product should conform to the relevant Bureau of Indian Standards for aluminium and aluminium alloys where a specification applies to the grade being supplied. Two safety standards deserve early attention: fine aluminium dust is a combustible dust hazard, so dust collection and housekeeping should follow the principles of NFPA 652 and NFPA 654, and aluminium dross and salt cake are listed hazardous wastes that must be cooled, stored under cover and consigned to authorised recyclers with a manifest trail. A fire risk assessment covering the molten metal area, fuel storage and the bag filter house rounds out the safety case.
Infrastructure Requirements (Mid-Sized Plant)
| Infrastructure Element | Specification | India-Specific Note |
|---|---|---|
| Land | 1 to 2.5 acres in an industrial estate, with separate scrap yard and finished goods area | Choose land already zoned for a secondary metal unit to simplify consent |
| Built-up area | 3,000 to 8,000 sq ft covering furnace hall, granulation bay, drying and screening section, packing hall, store, laboratory and office | Allow clear height and crane access in the furnace and granulation bays |
| Power | 250 to 750 kVA HT connection for furnace, atomiser compressor, dryer, screens and dust collection | Check state industrial tariff slabs and captive generation options |
| Water | 20 to 60 KL per day for quenching and cooling, designed for closed-loop recirculation | Groundwater abstraction may require a Central Ground Water Authority NOC |
| Furnace hall and molten metal handling | Non-combustible floor, refractory lining, protected fuel or gas supply, canopy hood and fume extraction over the furnace | Molten metal handling procedures should be documented for the state factory inspectorate |
| Effluent, dross and emission control | Effluent treatment for quench blowdown, covered dross and salt cake storage, pulse-jet bag filter on furnace and dryer stacks | Dross and salt cake are hazardous wastes requiring authorised disposal |
| Logistics and storage | Weighbridge, sheltered scrap yard, racked finished goods warehouse, container-capable approach road | Rail siding or port access is a decided advantage for scrap imports |
Infrastructure for an aluminium granules plant centres on furnace safety, closed-loop water management, and hazardous waste compliance, because operating licences and cost control both depend on getting these right from the start. Land already zoned for a secondary metal unit simplifies consent for an aluminium granules plant, while clear height and crane access in the furnace and granulation bays are essential design requirements. Dross and salt cake are classified hazardous wastes requiring authorised disposal, making covered storage and effluent treatment non-negotiable, and state power tariff slabs should be assessed early given the combined load of furnace, atomiser, and dust collection systems. Rail or port access adds a decided advantage for any aluminium granules plant dependent on scrap imports.
The equipment set runs in process order from scrap preparation through melting, granulation, drying, grading and packing, supported by laboratory and emission control equipment. Because the melting and granulation section is specialised, machinery choice is the least reversible decision in the project: a furnace and atomising line sized for one capacity is difficult to upgrade in place, so most promoters specify the line for the second phase of capacity at the outset and install screens, dryers and packing capability in stages.
Equipment selection should follow the grade mix rather than the other way round. A plant serving only foundries needs a melting furnace, a granulation arrangement and coarse screens, while a plant targeting AAC and atomised buyers needs controlled nozzle geometry, a better dryer, finer screens, an air classifier and a laboratory capable of measuring size distribution precisely. Automation should be added where it protects quality rather than where it merely reduces headcount: automatic pour-rate control, in-line weighing, dryer temperature control and bagging dust extraction all pay back through consistency, whereas automating coarse material handling rarely does. Vendor selection should weigh local service response heavily, because a furnace or atomiser that is down for want of a spare part stops the entire plant, and Indian secondary metal clusters generally have better service depth for domestic furnace builders than for imported equipment.
| Equipment | Function | Key Specification |
|---|---|---|
| Weighbridge and incoming inspection station | Scrap weighing, documentation and radioactivity check | 20 to 50 MT capacity with a radiation monitor |
| Shredder or shear with magnetic separator | Size reduction of oversize scrap and removal of iron | Throughput of 10 to 30 tonnes per day |
| Crucible or induction melting furnace | Melting, alloying and superheat control | 1 to 3 MT batch, 660 to 800 degrees Celsius, oil, gas or electric |
| Fluxing and degassing unit | Hydrogen and inclusion removal before granulation | Rotary degasser or flux injection with inert gas |
| Ladle and preheating station | Melt transfer without temperature loss | Graphite-lined or castable ladle preheated to 400 to 600 degrees Celsius |
| Atomisation chamber with nozzle plate or gas atomiser | Droplet formation from the molten stream | Perforated plate or concentric gas nozzle with controlled pour rate |
| Water granulation and quench tank | Solidification at controlled quench temperature | Recirculating quench water with temperature and flow control |
| Dewatering screen or centrifuge | Removal of quench water from the granule slurry | Continuous unit matched to the melt rate |
| Rotary or fluid-bed dryer | Moisture removal to despatch specification | Fuel-fired or electric, discharge moisture below 0.5 per cent |
| Multi-deck vibrating screens and air classifier | Size grading and removal of fines from saleable bands | Three to four decks, 0.05 mm to 10 mm separations, ISO 3310-1 sieves |
| Pulse-jet bag filter and dust collection system | Furnace, dryer and handling emission control | Sized and vented for combustible aluminium dust |
| Optical emission spectrometer and sieve analyser | Batch chemistry and particle-size quality control | Spark atomic emission spectrometry and ASTM B214 sieving |
| Weighing, bagging and stitching line | Dust-free packing into 25 kg bags and 1 MT jumbo bags | Net weigher with extraction hood and stitcher |
The cost of an Aluminium Granules Manufacturing Plant in India splits into a capital side, dominated by the melting and granulation line, and an operating side, dominated by the metal itself. The tables below give indicative shares for a mid-sized plant producing roughly 2,400 to 6,000 tonnes a year. Actual figures for your project will depend on capacity, the number of size bands graded, the degree of automation, the furnace fuel chosen, and whether land is owned or leased, which is why every range below should be treated as indicative.
Capital Expenditure (CapEx) Cost Structure
| CapEx Component | % of Total CapEx | What It Covers |
|---|---|---|
| Melting, granulation and atomisation line | 32% to 40% | Furnace, degassing unit, ladle, atomisation chamber, quench system and dryer |
| Land and civil construction | 18% to 24% | Industrial land, furnace hall, granulation bay, packing hall, stores and office |
| Auxiliary plant and utilities | 8% to 12% | Fuel storage, power distribution and transformer, effluent treatment, dust collection |
| Screening, classification and handling equipment | 8% to 12% | Vibrating screens, air classifier, conveyors, weighbridge, bagging line |
| Working capital margin | 10% to 14% | Scrap inventory cover and receivables from industrial customers |
| Approvals, pre-operative and consultancy | 3% to 5% | Consents, authorisations, project report and engineering consultancy |
| Contingency and site development | 4% to 6% | Site levelling, internal roads, unforeseen equipment and installation costs |
The melting and granulation line normally carries the largest single share, because the furnace, atomisation chamber, quench system and dryer are specialised items that are rarely available second-hand in serviceable condition. Working capital is the item first-time investors most often underestimate, since scrap is paid for on delivery while industrial customers buy on credit. Land and civil work should be sized for fuel storage, covered dross storage and a future second line from the outset.
Operating Expenditure (OpEx) Cost Structure
| OpEx Component | % of Total OpEx | India-Specific Note |
|---|---|---|
| Aluminium scrap and metal inputs | 66% to 74% | Price tracks primary metal and the London Metal Exchange; GST on scrap is levied under reverse charge |
| Furnace fuel and electricity | 8% to 13% | Oil or gas fired crucible furnaces dominate; state industrial tariffs and fuel contracts set the cost |
| Manpower and contract labour | 5% to 8% | Skilled furnace operators are scarce; contract labour handles scrap sorting and packing |
| Consumables, fluxes and refractories | 4% to 6% | Fluxes and crucibles are largely indigenous, with some nozzle and graphite items imported |
| Packaging, logistics and overheads | 5% to 8% | Inbound scrap freight and outbound bagged freight dominate this line in a low-value-per-tonne business |
Metal is the recurring cost that decides everything else. Aluminium scrap tracks primary metal and the London Metal Exchange, so a swing in scrap prices can erase a quarter of margin unless customer contracts pass the movement through. The practical levers are yield and grade mix: recovering more metal from every tonne of scrap, keeping fines out of the dust collector, and pushing a larger share of output into premium atomised and chemical grades.
Based on analysis of a mid-sized scrap-fed granule facility in India, the financial profile is sound but not spectacular, and it behaves like a metal conversion business rather than a branded product business: revenue is large relative to capital, gross margins are moderate, and profitability depends far more on the spread between scrap and granules than on scale alone. All figures below are indicative ranges for early planning.
| Financial Metric | Indicative Value | India Context |
|---|---|---|
| Total Investment | INR 8 Crore to INR 25 Crore | Covers land, plant, machinery and margin money for working capital on a 2,400 to 6,000 TPA plant |
| Revenue at Full Capacity | INR 55 Crore to INR 145 Crore | Depends on installed capacity and the share of premium grades in the sales mix |
| Gross Margin | 12% to 20% | Conversion margin between landed scrap cost and realised granule price |
| Net Profit Margin | 5% to 9% | After fuel, power, manpower, compliance costs and interest |
| IRR | 16% to 24% | Project IRR over a ten-year horizon at healthy utilisation |
| Payback Period | 3 to 5 Years | Faster where scrap is bought directly from industrial generators rather than through traders |
An aluminium granules plant at the 2,400 to 6,000 TPA scale requires a total investment of INR 8 to 25 Crore covering land, plant, machinery, and working capital. Revenue at full capacity ranges from INR 55 to 145 Crore, with gross margins of 12% to 20% reflecting the conversion spread between landed scrap cost and realised granule price. Net margins of 5% to 9% hold after fuel, power, manpower, compliance, and interest costs, and the project delivers an IRR of 16% to 24% over a ten-year horizon. Payback is faster for operators who source scrap directly from industrial generators rather than through traders.
Key Risks and Mitigation
Approvals sit on the critical path for this project, because a secondary aluminium melting unit cannot be built without consent to establish, cannot be commissioned without consent to operate, and cannot store or dispose of dross without hazardous waste authorisation. Promoters planning to establish an Aluminium Granules Manufacturing Plant in India generally need the following before commencing operations.
The common thread running through these developments is that India's secondary aluminium chain is being formalised from both ends: policy is making scrap a documented, bankable input, while emissions reporting and steel quality requirements are raising the specification standards that buyers expect from granule suppliers. For a new entrant in 2026, the implication is straightforward. Plants that build laboratory capability, batch traceability and a documented scrap supply chain into the project from the start will be positioned to serve steel, AAC and export-facing customers, while plants that compete only on price against informal remelt units will find their margin compressed by the same policies that created the opportunity.
A comprehensive Aluminium Granules Project Report and Detailed Project Report sets out the case in the order a lender, a state industrial development corporation, an incentive scheme administrator or an equity partner needs it. That means the demand picture by grade and segment with a named list of steel, AAC, foundry and chemical buyers in the target radius; the feedstock plan covering scrap sources, alloy families, documentation for imports, landed cost basis and inventory policy; the process configuration covering melting, refining, granulation or atomisation, drying and grading; the site and layout including the furnace hall, granulation bay, covered dross storage and expansion space; machinery specifications with vendor quotations and performance guarantees; the statutory approval route with the status of pollution control consents and hazardous waste authorisation; and the full economics with sensitivity analysis.
The exercise is not academic. It forces the promoter to answer, before capital is committed, what happens to margin if scrap prices rise ten per cent while annual sales contracts stay fixed, what fines yield the selected nozzle geometry will actually produce, how much of each size band the target customers will really buy, and how many days of receivables the chosen customers will demand.
At the centre of the document is an Aluminium Granules Financial Model covering revenue by grade and customer, metal cost by source with price scenarios, yield and recovery by process step, fuel, power and manpower cost build-up, working capital tied up in scrap inventory and industrial receivables, capital cost tied to vendor quotations, cash flows, break-even analysis, IRR and payback over a ten-year horizon. Because the largest uncertainties are the scrap-to-granule spread, the fines yield and the payment cycle of industrial buyers, a sound report tests the project across a range of scrap prices, grade mixes and utilisation rates rather than presenting a single optimistic case.
This is also where an experienced Aluminium Granules Plant Project Report Consultant in India, an Aluminium Granules Business Plan Consultant in India or an Aluminium Granules Manufacturing Feasibility Study Consultant adds value that is hard to assemble in-house: process assessment, feedstock market knowledge, approval sequencing and financial modelling discipline. Many promoters also commission a separate Aluminium Granules Business Plan to sit alongside the DPR when approaching equity investors rather than lenders, because the two documents answer different questions about the same project.
What are the first steps to set up an aluminium granules manufacturing plant in India?
Begin with the grade mix and the feedstock, not the site. Decide whether you will serve steel deoxidation, AAC, foundry or atomised buyers, confirm where sorted scrap will come from and at what landed cost, and commission an Aluminium Granules Project Report before ordering long-lead equipment. Then secure industrial land zoned for secondary metals, obtain pollution control consent to establish, and start the furnace and granulation line order. Indicatively, twelve to eighteen months from decision to commissioning is realistic.
How much does it cost to set up an aluminium granules manufacturing plant in India?
Indicatively, a plant producing 2,400 to 6,000 tonnes a year requires INR 8 Crore to INR 25 Crore. This Aluminium Granules Manufacturing Plant Cost covers land, civil construction, the melting and granulation line, drying and screening equipment, utilities, emission control, approvals and the margin money for working capital. Scrap inventory and customer receivables are a substantial part of the requirement and scale with the capacity you choose.
What are the main steps in aluminium granules manufacturing?
The Aluminium Granules Manufacturing Process runs from scrap receipt, sorting and preparation through charge make-up, melting at 660 to 780 degrees Celsius, refining and degassing, and melt holding at the atomisation temperature. The melt is then granulated through a perforated plate into water or atomised with a gas jet, quenched, dewatered, dried, screened into size bands, air-classified, de-dusted, tested and packed.
Which machinery does an aluminium granules manufacturing plant need?
Key equipment includes a weighbridge and radiation monitor, a shredder or shear with magnetic separation, a 1 to 3 MT crucible or induction melting furnace, a fluxing and degassing unit, a preheated ladle, an atomisation chamber or nozzle plate, a water quench tank with recirculation, a dewatering screen or centrifuge, a rotary or fluid-bed dryer, three to four deck vibrating screens with an air classifier, a pulse-jet bag filter, and a spectrometer for batch chemistry.
What raw materials are used to make aluminium granules?
The dominant input is aluminium scrap, comprising runners, risers, turnings, extrusions and old sheet, which accounts for an indicative 66 to 74 per cent of operating cost. Aluminium ingot and hardener alloys correct the chemistry, while melting and degassing fluxes, crucibles and refractories, treatment chemicals, water and packaging materials make up the balance. Imported scrap requires a pre-shipment inspection certificate from a recognised agency.
How profitable is aluminium granules manufacturing in India?
A well-run plant with assured scrap supply, disciplined yield control and a firm industrial customer base can earn an indicative gross margin of 12 to 20 per cent, a net profit margin of 5 to 9 per cent and an IRR of 16 to 24 per cent, with payback in three to five years. The profitability of Aluminium Granules manufacturing business in India depends most on the spread between scrap purchase cost and granule selling price, and on the share of premium grades sold.
