What Are Bentonite Granules?
Bentonite is a naturally occurring clay material known for properties such as hydration, swelling, water absorption, viscosity and thixotropy. After extraction and processing, Bentonite can be screened into granules or milled into powder, depending on the intended industrial application.
Bentonite granules are available in different particle sizes, colours, mineral compositions and processing conditions. Choosing the appropriate product depends on the intended use, required performance, moisture level and manufacturing process.
Common Types of Bentonite Granules
Raw Bentonite Granules: Raw Bentonite granules retain their natural mineral characteristics and are commonly supplied for agricultural products, mineral processing and industrial formulations.
Sodium Bentonite Granules: Sodium Bentonite is recognised for its strong swelling and water-retention characteristics. It is commonly considered for drilling, sealing, construction, environmental barriers and clumping pet-litter products.
Calcium Bentonite Granules: Calcium Bentonite provides absorption and adsorption properties suitable for selected pet-care, agricultural and industrial formulations.
Roasted Bentonite Granules: Roasted Bentonite granules undergo thermal processing to reduce moisture and develop a dry, porous structure. They can be used as carriers in compatible fertilizer, pesticide and absorbent products.
Black and Brown Bentonite Granules: These products are selected for applications where natural colour, particle appearance and formulation compatibility are important.
Major Applications of Bentonite Granules
Agriculture and Fertilizer: Bentonite can be used as a mineral carrier, soil-conditioning material and processing aid in selected fertilizer and agricultural input products. Thermally processed Bentonite may also serve as a porous carrier for certain pesticide and herbicide formulations.
Pet Care: Bentonite granules absorb liquid and can form removable clumps, making them widely used in cat-litter products.
Drilling and Borewell: Drilling Grade Bentonite helps support viscosity development, borehole-wall sealing, drill-cutting removal and lubrication.
Foundry Industry: Foundry Grade Bentonite acts as a bonding material in green-sand moulding for iron, steel and non-ferrous castings.
Construction and Environmental Projects: Selected Sodium Bentonite products are used in diaphragm walls, foundations, tunnelling, landfill barriers and geosynthetic clay liners.
Before selecting a product, buyers should consider:
Intended industry and application
Sodium or Calcium-based composition
Required granule or particle size
Moisture and absorption requirements
Swelling or clumping performance
Colour and product appearance
Packaging and order quantity
Application testing is recommended because Bentonite performance can vary depending on mineral composition, processing method and formulation conditions.
