What is a bentonite clay granules project report?
A bentonite clay granules project report is a detailed project report (DPR) for a plant that crushes raw bentonite lumps, roasts them in a rotary dryer and screens them into mesh-sized granules. It sets out the process, machinery, raw clay sourcing, project cost, means of finance, five-year projections, DSCR and break-even.
Promoters near the bentonite belts of Gujarat and Rajasthan use it to size the plant and raise a term loan; banks use it to judge whether thin, freight-sensitive margins can repay the debt.
Also known as: roasted bentonite granules project report, bentonite granules business plan, DPR for bentonite granules plant, bentonite granules manufacturing project report.
Bentonite clay granules plant cost and economics
Our sample report models a plant making 87 metric tonnes per day (MT per day) over 300 working days, or 26,100 MT a year. It starts at 60% capacity, reaches 80% in Year 5 and sells granules at ₹5,170 per MT ex-works.
Granules are a low-price, high-volume product, so profit sits in a narrow band. The average debt service coverage ratio (DSCR, the cash available to pay each rupee of loan instalment) is 1.38, with a lowest year of 1.20. Lenders will look hard at that margin.

Bentonite clay granules manufacturing process
The plant turns mine-run lumps into graded granules in seven steps. There is no chemical reaction: the skill lies in crushing for the right size with few fines and drying to a hard, low-moisture granule.
- Stockpiling and sun drying
Lumps from the mine are sorted by grade and spread in the yard so surface moisture escapes before they reach the crusher.
- Primary crushing
A jaw crusher breaks the lumps into pieces small enough to feed the granulator evenly.
- Granulating
A roll crusher reduces the clay to granules of a few millimetres; roll gap and feed rate decide how much fine powder is created.
- Drying and roasting
A rotary dryer fed by a fuel-fired hot air generator drives out moisture and hardens the granules. Single roasted grades pass once, double roasted grades twice.
- Screening
Multi-deck vibrating screens split the output into buyer grades such as 10x20, 12x25 and 16x35 mesh; oversize goes back to the roll crusher.
- Dust collection
A pulse jet bag filter captures dust from the dryer and screens, and the fines are sold as bentonite powder instead of being wasted.
- Packing
Each grade is weighed and packed in 25 or 50 kg HDPE bags or jumbo bags for dispatch.
Roasted or unroasted: which bentonite granules to make
The grade you sell decides how big the dryer must be and how much fuel you burn. Most plants make two or three grades on one line and change the mix with the season.
| Unroasted granules | Crushed, dried only enough to screen, and sold at the lowest price. Suited to buyers who process them further, such as sealing and some fertiliser blends. |
|---|---|
| Single roasted | One pass through the rotary dryer. Harder and less dusty than unroasted, and the common grade for fertiliser and micronutrient carriers. |
| Double roasted | Two passes, the hardest and driest grade. Pesticide formulators prefer it because granules keep their shape during coating; it costs more in fuel and dryer time. |
| Mesh sizes | 10x20 and 12x25 mesh are the common agricultural sizes, with 16x35 for finer carriers. Litter and sealing grades are sized to each buyer's order. |
| What buyers test | Size distribution on a sieve shaker, moisture, bulk density, hardness and dust. Results are agreed with each buyer and checked on every lot. |
Grade descriptions reflect common trade practice in India as of October 2026. Buyer specifications vary.
Raw bentonite: supply and cost
The only real input is raw bentonite, a clay made mostly of the mineral montmorillonite. The Indian Bureau of Mines puts India's bentonite resources at 583 million tonnes, with Rajasthan holding 73% and Gujarat 25%.
Freight on lumps makes up a fifth of raw material cost in our sample, and raw materials are 43.1% of sales. Every extra kilometre between mine and plant adds to the cost of each tonne of granules.
| Raw material | Share of cost | Year 3 (₹ lakh) |
|---|---|---|
| Raw bentonite lumps from mine | 80% | 325.69 |
| Freight on lumps from mine to plant | 20% | 81.42 |
| Total | 100% | 407.11 |
Machinery for a bentonite granules plant
The rotary dryer and roaster is the largest single item, about a third of the machinery cost in our sample. Its size and burner choice set both capacity and fuel cost, so it deserves the most attention when you compare quotations.
| Machine | What it does | Sample cost (₹ lakh) |
|---|---|---|
| Jaw crusher | Breaks mine lumps for the granulator | 25.41 |
| Roll crusher granulator | Sizes clay into granules | 35.58 |
| Rotary dryer and roaster with hot air generator | Dries and hardens granules | 81.33 |
| Multi-deck vibrating screens | Separates mesh grades | 25.41 |
| Bucket elevators and belt conveyors | Move material between stages | 25.41 |
| Pulse jet bag filter dust collector | Captures dust and fines | 25.41 |
| Bag filling and stitching machine | Weighs and closes bags | 12.71 |
| Wheel loader | Feeds lumps from the yard | 15.25 |
| Laboratory sieve shaker and moisture meter | Checks size and moisture of each lot | 7.63 |
| Total plant and machinery | 254.14 | |

Fuel, power and manpower
After raw clay, energy is the biggest running cost. Wet lumps in the monsoon months raise dryer fuel use, which is why sun drying in the yard matters.
| Power and fuel | ₹129.83 lakh in Year 3, or 13.7% of sales, for the dryer's hot air generator, crushers, screens, elevators and bag filter |
|---|---|
| Manpower | 37 people: 6 in management and supervision, 13 skilled operators and 18 semi-skilled and unskilled workers |
| Wages | ₹69.72 lakh in Year 1, rising 5% a year |
| Land and building | Land ₹50.85 lakh and building ₹125.09 lakh, with a covered store for lumps and bagged granules so the monsoon does not wet the stock |
| Raw material stock | 60 days of lumps, as mine supply and yard drying slow in the monsoon |
Values are from our illustrative sample report.
Licences and approvals for a bentonite granules plant
| Business registration | Udyam (MSME) registration and GST registration |
|---|---|
| Pollution board consent | Consent to establish and consent to operate from the State Pollution Control Board. Mineral processing, grinding and pulverising units are listed in the Orange category under CPCB criteria; confirm the category with your state board |
| Mineral storage | Bentonite is declared a minor mineral, so state rules apply. Some states require a storage or dealer licence from the mines and geology department to stock and process lumps |
| Factory and fire | Factory licence where worker and power thresholds apply, and a fire NOC where required; rules vary by state |
| Quality standards | BIS standards cover industrial bentonite: IS 6186 (chemical, rubber and oil-well drilling uses) and IS 12446 (foundries). Agricultural carrier granules are usually sold to the buyer's own specification |
Who buys bentonite clay granules in India
Agriculture drives most domestic demand. Fertiliser, micronutrient and pesticide makers coat granules with active ingredients, so orders build ahead of the kharif and rabi sowing seasons and slow in between.
Cat litter and sealing grades sell at better prices and reach export buyers, but they need tighter size, absorbency and dust control. Bulk agricultural granules are traded mostly from Gujarat and Rajasthan, at indicative ex-works prices of about ₹3,000–6,000 per MT as of October 2026.
- Fertiliser and micronutrient manufacturers
- Pesticide and agrochemical formulators
- Pet litter brands and exporters
- Borewell drilling and civil sealing contractors
- Agri input distributors and traders
Where a new plant wins: buyers compare delivered cost per tonne, not only the ex-works price. A plant near the deposits that sells two or three grades, and sells its fines as powder, can hold its margin when agri demand is slow.
Mistakes that weaken a bentonite granules project report
- Assuming every tonne becomes granules
Crushing always creates fines that fall below the smallest mesh. A report that prices all output at granule rates overstates sales; fines sell at powder prices.
- Pricing raw clay at the mine gate
Freight is a fifth of raw material cost in our sample. Leave it out and the margin looks far better than it will be.
- Using dry-season fuel figures all year
Wet lumps in the monsoon need more heat in the dryer. Fuel should be costed on a yearly average, not on dry months.
- No stock built for the monsoon
Mines and yard drying slow in the rains. Without stock of lumps in working capital, the plant stands idle just before the rabi buying season.
- Selling only to one agri season
A plan that depends on one crop season leaves long idle months. Lenders look for a second grade or market to keep capacity use steady.

Bentonite Clay Granules project report: frequently asked questions
How much does it cost to set up a bentonite clay granules plant in India?
A plant making 25–40 MT per day needs roughly ₹2–3.5 crore, and one making 80–100 MT per day about ₹5–7 crore, including land, building and working capital margin. Our sample report models an 87 MT per day plant at ₹533 lakh. These are indicative figures; your report works out the cost for your capacity, location and fuel.
What are bentonite clay granules used for?
In India most granules are carriers: fertiliser, micronutrient and pesticide makers coat them with active ingredients for field application. Other uses are cat and pet litter, sealing bore wells, ponds and landfill liners, and absorbing oil spills. Each use asks for a different mesh size, hardness and moisture, so the plant should be planned around its main buyers.
What is the difference between roasted and unroasted bentonite granules?
Unroasted granules are only crushed, dried and screened. Roasted granules pass through a heated rotary dryer, once for single roasted and twice for double roasted, which lowers moisture and makes them harder and less dusty. Agrochemical formulators usually prefer roasted grades because the granules hold their shape during coating and bagging, and they pay more for them.
Is a bentonite granules business profitable?
It can be, but margins are thin. In our illustrative sample, an 87 MT per day plant earns a 14% return on investment in Year 3. It breaks even at 48% of capacity and pays back in about 4.6 years. Profit depends mostly on the delivered cost of raw lumps, dryer fuel, granule yield and how evenly sales spread across the year.
Where should a bentonite granules plant be located?
Close to the raw clay. The Indian Bureau of Mines records Rajasthan and Gujarat as holding about 98% of India's bentonite resources. Bhavnagar and Kachchh in Gujarat and Barmer in Rajasthan are the main producing districts. Freight on lumps is a fifth of raw material cost in our sample, so a plant far from the mines starts at a disadvantage.
Which licences are needed for a bentonite granules plant?
Udyam and GST registration, consent to establish and operate from the State Pollution Control Board, a factory licence where thresholds apply, and fire and power approvals. Bentonite is a minor mineral, so the state mines department may require a storage or dealer licence for stocking lumps. Mineral grinding and pulverising units generally fall in the Orange pollution category.
Is the sample report free and can I use it for a bank loan?
The sample is free to view and download. It is an illustrative report that shows the format and depth of an NPCS report. Its figures are representative and not based on a real project, so it should not be submitted to a bank. For a loan, NPCS prepares a report for your own capacity, location and lender.
