JHM Ball Mill

Designed and developed independently by us, the JHM ball mill is a new type ball grinder with internal classifying impeller, integrating the size reduction and classification. It wins the national patents of invention and utility model, filling the blank in this filed at home.

Working Principle
Entering the grinding chamber of cylinder, the material is raised by rotating cylinder with the grinding media into certain height. When the piled surface of the media inclines at the angle that exceeds the natural piling angle, the grinding media will fall off, so do the materials. Both of them will crash, shear, extrude and grind mutually to get the materials smashed. Then the powdered materials will be classified immediately by classifier. The coarse powder will be returned for continuous grinding and the qualified powder will be collected by the sequence device.

Product Features
1.This ball mill integrates the size reduction and classification. Qualified product is immediately gotten thus overgrinding is avoided and grinding efficiency is improved.
2. This product enjoys simpler production process and occupies smaller space, compared with traditional one.
3. The directional reverse blowing wind reduces the temperature in the grinding chamber. It enables the product to realize the pulverization and classification of the materials sensitive to heat, offering a wider applied range than the conventional machine.
4. The negative pressure operation prevents the dust leakage.

The ball mill is suitable for the battery material, metal dust, abrasives, building materials, non-metal ores and more. Grinding media like alumina ball is applicable for the materials with requirement of super purity and narrow size distribution.
