Bentonite, with a hardness of 1-2 and a density of 2-3g/cm3, is a non-metallic mineral with montmorillonite as its main mineral component. It is generally white and yellow.

Bentonite Grinding Processing

1. Na-bentonite stage: In nature, the performance of calcium-based bentonite is worse than that of sodium-based bentonite.
2. Drying stage: Sodium-treated bentonite has higher moisture content and needs to be dried to a smaller moisture content.
3. Grinding stage: After drying, the bentonite is crushed, and the ore is lifted. Then the electromagnetic vibration feeder feeds the main grinder and grinds in the grinding chamber.
4. Classification stage: The material is classified by the separator.
5. Pulverizing stage: Fine powder enters the pulverizing system, and the pulverized powder is separated. The finished powder is transported, and then packed.

Core Equipment


Application & Specification

Application: used as feed

Production Fineness: <200mesh

Bentonite is widely used in agriculture, light industry, cosmetics, pharmaceuticals and other fields, such as fish feed.

Application: used in drilling, papermaking and other fields

Production Fineness: 200-325mesh

It can be used for drilling mud and flame retardant because of its good water absorption, expansion and pulping properties. It can also be used as filler in paper industry.

Application: used for making purifiers, etc.

Production Fineness: >325mesh

Bentonite has adsorption and cation exchange properties, and can be used to remove toxins from cooking oil, purify gasoline and kerosene, and treat wastewater.
