Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.

Bentonite is used as a binder for proper balling of the filter cake particles in to spherical shaped balls with certain compression strength. The bentonite is stored and ground in a Vertical mill by dry grinding process to desired fineness (−200 mesh, 80%). The powdered bentonite is stored for further mixing process.
