Bentonite is a non-metallic mineral with active chemical properties. It is widely used in various industries for its excellent hygroscopicity and expansion. However, bentonite must be processed and ground before it can be put into use.
Bentonite is mainly composed of montmorillonite. Its unique 2:1 crystal structure consists of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedrons. Since there are unstable cations (such as Cu, Mg, Na, K, etc.) in the layered structure of montmorillonite unit cells, these cations are easily exchanged by other ions, so bentonite has excellent ion exchange properties.

Working principle of bentonite Raymond mill
The bentonite crushed and screened by the crusher is uniformly fed into the feed port of the bentonite Raymond mill, and then enters the grinding chamber of the main machine through the feed port for grinding.
The material is scooped up by the shovel and sent to the middle of the grinding roller and the grinding ring. The material is crushed into powder under the action of the grinding pressure, and then the powdered material is blown up by the fan and passed through the analyzer. The material that meets the fineness requirements passes through the analyzer.
The material that does not meet the requirements returns to the grinding chamber for further grinding, and the material that passes through the analyzer enters the cyclone separator for separation and collection.
Bentonite Raymond Mill Performance Advantages
It has strong pressure resistance and can be used for various materials with Mohs hardness below 9.3.
The grinding roller device of bentonite Raymond Mill adopts a high-efficiency processing technology. The overlapping multi-stage seal ensures a good sealing effect, and the replacement cycle of the grinding roller and grinding ring is long, eliminating the disadvantage of the short replacement cycle of the consumable parts of the centrifugal crusher.
The grinding device adopts overlapping multi-stage seals, which has good sealing and dust removal effects.
