Dry Ball Mill Working Principle:
The dry ball mill is a horizontal cylindrical rotary device with external gear drive, two storehouses, and lattice type. The material enters the first bin of the mill uniformly through the feeding device through the hollow shaft, in which there are stepped linings or corrugated linings. When steel balls of different specifications are loaded inside, the centrifugal force generated by the rotation of the cylinder brings the ball to a certain height and then falls down, causing heavy impact and grinding on the material. After the material has been rough ground in the first warehouse, the material enters the second warehouse through a single layer partition plate, which is lined with a flat liner. The material is further ground with steel ball. The powder is discharged through the grate plate to finish the grinding operation.

Dry Ball Mill Application:
Dry ball mill, also called dry grinding machine, is mainly used for grinding finished products and raw materials in cement factories, and also for grinding all kinds of ores and other grindable materials such as metallurgy, chemical industry, electric power, etc. The materials must be dry, It is suitable for cement, silicate products, new building materials, refractories, chemical fertilizers, black and non-ferrous metals ore dressing and glass ceramics and other production industries


Dry Ball Mill Features:
1.Can be used for open-flow grinding line, but also suitable for the circulatory grinding line with the separator.
2.Dry ball mill has the characteristics of strong adaptability to materials, continuous production and easy speed regulating grinding products fineness.
3.Dry ball mill feed the material can not be high, otherwise the material bond, discharge and other problems.
4.Dry ball mill outlet is straight-tube shape, but also equipped with the wind device, dust removal.
