BENTONITE POWDER
Bentonite is as a mud constituent for oil- and water- 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

Foundry Grade Bentonite:
All cast iron, steel & malleable iron foundries are almost using Bentonite with cost efficient results, kutch region is famous for a very good sodium Bentonite for casting industries. For continuous mould making also kutch Bentonite is used successfully. Our foundry grade Bentonite powder gives good flow ability. Compact ability and thermal stability for the production of high quality castings.
We maintaining following parameter which help to make high quality castings
- High gelling time which gives high strength in less mulling time
- pH Maintaining
- Active clay maintaining
- High strength on good compatibility

Construction Grade Bentonite:
Bentonite in civil engineering applications is traditionally used as a thixotropic, support and lubricant agent in diaphragm walls and foundations, in tunnelling, 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:
Our bentonite is unique Sodium based Bentonite. Our IOP grade bentonite is 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 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.
