Bentonite
Bentonite is a versatile clay composed mainly of montmorillonite, known for its exceptional swelling, absorption, and binding properties. It is classified primarily into Sodium Bentonite and Calcium Bentonite, each suited for specific industrial applications. At Gajanan Clay Chem LLP, we specialize in the processing and supply of high-quality Bentonite tailored to the requirements of a wide range of industries including foundry, drilling, construction, and more.

Applications
Foundry Industry
Used as a binder in green sand molds to enhance strength and cohesion for ferrous and non-ferrous metal casting.
Drilling Fluids (Oil & Gas)
Sodium Bentonite is a key component in drilling muds for cooling drill bits, removing cuttings, and maintaining borehole stability.
Construction & Civil Engineering
Used in waterproofing, piling, and diaphragm wall construction due to its swelling and sealing capabilities.
Iron Ore Pelletizing
Acts as a binder in pellet formation for smooth handling and improved furnace performance.
Cat Litter
Highly absorbent Bentonite is used in pet hygiene products for effective odor and moisture control.
Agriculture
Improves soil conditioning, water retention, and nutrient exchange for better crop yield.
