Our Bentonite Products: Foundry Grade: The foundry-grade bentonite powder is used as a bonding material in the preparation of moulding sand for the production of iron, steel, and non-ferrous casting. Sodium Bentonite is the preferred binding agent for use in the bonding of metals and foundry sands, although calcium Bentonite enhances foundry sandâ??s flow ability and figures in the manufacture of nonferrous mouldings. Drilling Grade (API Grades, OCMA) Drilling-grade bentonite is a naturally occurring clay containing the clay minerals of smectite. It can also contain accessory minerals, such as quartz, mica, feldspar, and calcite. The Drilling Grade Bentonite Powder is used as a mud constituent for oil and water well drilling. Its roles are mainly to seal the borehole walls, remove drill cuttings, and lubricate the cutting head. Our Drilling Grade Bentonite Powder has high swelling and good colloidal nature, which can increase the viscosity of suspension in the drilling mud and also can increase the lubrication of drilling, as well as for the rig-freeing agent. Piling Grade Bentonite slurry is one of the most common excavation fluid used in constructing diaphragm walls. The gel strength and viscosity properties of the bentonite clay allow for cutting suspension and removal. Piling Grade Bentonite Powder is used traditionally as a support and lubricant agent in walls and foundations, tunnelling, and horizontal drilling. Viscosity and plasticity play a very important role. Bentonite slurry walls are used in construction, where the slurry wall is a trench filled with a thick colloidal mixture of Bentonite and water. Cattle Feed Grade Our Feed Grade Bentonite is Natural & selected from affluent Mines of Kutch. This Bentonite is used as an animal feed supplement, as a palletizing aid in the production of feed pallets, as well as a flow ability aid. It slows the passage of feed through the digestive system increasing the uptake of nutrients. Bentonite has an affinity for some of the active elements of toxin products formed by bacteria in the digestive tract, and its application in feed allows more rapid weight gain of livestock.
