Bentonite (Powder & Lumps)

Bentonite is a clay generated frequently from the alteration of volcanic ash, consisting predominantly of steatite minerals, usually montmorillonite. Bentonite presents strong colloidal properties and its volume increases several times when coming into contact with water, creating a gelatinous and viscous fluid. The special properties of Bentonite (hydration, swelling, water absorption, viscosity, thixotropy) make it a valuable material for a wide range of uses and applications.

Foundry Grade

All cast iron, steel & malleable iron foundries are almost using Bentonite with cost efficient results. Our foundry grade Bentonite powder gives good flow ability. Compact ability and thermal stability for the production of high quality castings.

We maintain following parameter which help to make high quality castings

  • High gelling time, which gives high strength in less mulling time
  • Maintains pH
  • Maintains Active clay
  • High strength on good compatibility

Drilling Grade

Bentonite is as a mud constituent of oil and water for well drilling. Its role is mainly to seal the borehole walls, to remove drill cuttings and to lubricate the cutting head. The special higher mud yield results in using less quantity of Bentonite for the same standard mud. This results in lesser requirement of Bentonite.

  • Retains thixotopic properties when met with brine and high temperature in deep drilling
  • Gives high barrel yield
  • Withstands formation pressure

Construction Grade

Bentonite in civil engineering applications is traditionally used as a thixotropic, support and lubricant agent in diaphragm walls and foundations, in tunneling, in horizontal directional drilling (HDD) and pipe jacking. Bentonite, due to its viscosity and plasticity, is also used in Portland cement and mortars.

Iron Ore Palletizing Grade

Our Bentonite is unique Sodium based Bentonite. Our IOP grade Bentonite is an extraordinary solution for Iron Ore Pellet binding and it can also withstand higher temperature since it contains more percentages of metal. The grade is also having a higher natural percentage of Iron which is ideal in isolating ore pellets with the maximum percentages of Iron. The Iron Ore Pelletization plant can able to maintain active clay levels with reduced additions of Bentonite since IOP grade Bentonite is having high Mont values. It also offers more superior thermal durability.
