Roasted Bentonite Granules Producer and Global Supplier
Trusted Roasted Bentonite Supplier Across India and Worldwide
Leading Producer, Manufacturer, and Supplier of Roasted Bentonite in India Manufacturers and Suppliers of Roasted Bentonite HTMC Group proudly stands as a premier producer, manufacturer, and supplier of high-quality Roasted Bentonite in India. With extensive expertise and a commitment to excellence, we deliver top-notch Roasted Bentonite products tailored to meet the diverse needs of various industries.
Roasted Bentonite is a heat-treated form of natural bentonite clay, produced by roasting raw bentonite lumps at controlled high temperatures. This thermal process removes moisture, hardens the granules, and makes them chemically inert, sterile, and highly stable. Roasted bentonite is valued for its strong liquid-holding capacity, uniform granule structure, and ability to release absorbed active ingredients slowly, which makes it an ideal carrier material for agricultural and industrial formulations.
HTMC Group is a well-established roasted bentonite manufacturer in India, known for producing consistent, stone-free and free-flowing granules for both domestic and international buyers. As a dependable Roasted Bentonite Supplier in India , we follow strict process controls at every stage, from raw material selection to roasting temperature and final packaging, to ensure every batch meets the purity, hardness and particle-size standards our customers expect. Our production capability and quality systems allow us to serve clients not just across India but in every corner of the world, supplying agriculture, fertilizer, pesticide and industrial sectors on a truly global scale.
Enquire NowWhat We Do
At HTMC Group ,we specialize in the production and supply of Roasted Bentonite, also known chemically as sodium montmorillonite or sodium bentonite, with the formula Na2(Al2Si4O10)(OH2)⋅nH2O Our advanced manufacturing processes ensure that our Roasted Bentonite meets the highest standards of quality and purity, making it suitable for a wide range of industrial applications.
Variety of Quartz We Provide
High-grade, stone-free bentonite clay is sourced from our mining and processing units. The raw clay is first crushed into smaller lumps to prepare it for uniform roasting and to remove any foreign matter such as stones or organic debris.
2. Roasting at Controlled Temperature
The crushed bentonite is roasted in rotary kilns or roasting furnaces at high temperatures, typically around 600 to 700 degrees Celsius. This step drives out natural moisture, hardens the clay structure, and gives the granules their characteristic dark, calcined appearance. Roasting also makes the material inert and sterile, which is important for agricultural and pharmaceutical carrier applications.
3. Cooling and Granulation
Once roasted, the material is gradually cooled and passed through granulation equipment to form uniform granules. This step is critical to achieving the free-flowing, non-dusty texture that customers expect from good-quality roasted bentonite.
4. Screening and Mesh Sizing
The granulated bentonite is screened through multiple sieves to separate it into different sizes, including fine mesh grades and coarser sizes such as 10mm Roasted Bentonite Granules. Screening ensures that each grade is consistent in size for reliable performance in the intended application.
5. Quality Testing
Every batch undergoes testing for moisture content, bulk density, liquid-holding capacity, pH, and hardness before it is approved for dispatch. This ensures that the granules meet agreed technical specifications for each customer.
6. Packaging and Storage
The finished roasted bentonite granules are packed in moisture-resistant bags and stored in a dry, ventilated warehouse to preserve their quality until they reach the customer, whether in India or overseas.

Industrial Applications of Roasted Bentonite
Iron Ore Pelletizing: Used as a binder to enhance the quality of iron ore pellets.
Oil and Gas Drilling: Acts as a viscosity and filtration control agent in drilling fluids.
Foundry: Utilized as a bonding material in the production of green sand molds.
Agriculture: Improves soil quality and acts as a carrier for pesticides and fertilizers.
Water Treatment: Used in the clarification of drinking water and wastewater treatment.
Construction: Serves as a waterproofing agent and stabilizer in various construction applications.

Safe Handling and Storage
To preserve the quality of roasted bentonite granules, store them in a cool, dry, and well-ventilated warehouse away from direct moisture and sunlight. Keep bags stacked on pallets to avoid contact with damp flooring, and reseal opened bags promptly to prevent moisture absorption, since exposure to humidity can affect the granules' liquid-holding capacity. Basic protective equipment such as gloves and a dust mask is recommended while handling bulk quantities. Avoid storing the product near strong acids or reactive chemicals to maintain granule integrity during storage and transit.
