At present, more and more bentonite powder has been used in the oil drilling industry. The bentonite powder can make the formation of waterproof layer and prevent the mud from modifying.
Generallly speaking, the bentonite is often ground into 200-325mesh powder with 30% moisture without the modification. If you want to grind such good bentonite powder, Clirik Raymond grinding mill is the best choice. 

Clirik High Pressure grinding Mill is an improved type of Raymond grinding mill. The purpose of the this kind mill is to grind non-flammable and non-explosive materials in the fields of building materials, mining, metallurgies and chemical industry with hardness less than 9.3 in Moh’s scale and humidity less than 6 percent. Examples of the materials are: quartz, feldspar, barite, fluorite, dolomite, garnet, bauxite, zircon, marble, calcite, iron ore, rock phosphate, coal, slag and so on(400 kinds of material). The granularity of the final products can be changed from 30 to 425 meshes
