Overflow Type Ball Mill Overview:

The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.

Overflow Type Ball Mill Features:

1. The jack-up device of wet grate ball mill makes maintenance easy.
2. The hydrostatic and hydrodynamic bearings ensure the smooth operation of wet grate ball mill.
3. The low speed transmission of wet grate ball mill contributes to easy overhaul and maintenance.
4. The oil-mist lubrication device guarantees reliable performance of bearings.
5. The gas clutch adopts the flexible start-up model.

Working Principle :

Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes materials to the outlet and the grinded materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow. There are backpitch impellers in the hollow shaft, which can make the balls and coarse ores in the overflow return to the mill. With simple structure, higher operation rate, and rolling bearing, the energy conservation is significant.
