Low Energy-Consumption 1-45 t/h Capacity Bentonite Powder Grinding Mill Equipment
Description
Bentonite has good physical and chemical properties, and can be used as binder, suspending agent, thixotropic agent, stabilizer, purification and decolorizing agent, filler, feed, catalyst, etc. It is widely used in agriculture, light industry, cosmetics, pharmaceuticals and other fields, so Bentonite is a versatile natural mineral material. The raw ore is selected and refined to produce special bentonite suitable for ceramic production
【Working Principle】
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when passing through the annular groove on the grinding disc.
The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is ground together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.

【Structure and Composition】
HVM series ultra-fine vertical mill is mainly composed of electric motor, reducer, grinding wheel device, grinding disc device, pressurizing device, powder separator, feeding device, oil station, main engine, electric control system and other parts.
1. Grinding wheel device: the main part of the material to be rolled, without power output, it operates passively due to the frictional force in contact with the material.
2. Grinding disc device: The grinding area of the material is connected to the reducer and rotates by itself.
3. Pressurizing device: control the gap between the grinding wheel and the grinding disc to ensure the grinding wheel pressure during the grinding process.
4. Powder Separator: The multi-head powder separation structure uses the principle of rotating centrifugal force to realize the fine powder screening and filtration work in continuous production. It is an efficient and energy-saving powder separation device.
