Overflow Type Ball Mill
- 【Introduction】:
- 【 Capacity 】:
- 【Improvement】:
【Advantages】
Jack-up device, easy maintenance;
The hydrostatic and hydrodynamic bearings ensure the smooth operation;
Low speed transmission is easy for starting and maintenance;
The oil-mist lubrication device guarantees reliable performance of bearings;
The gas clutch adopts the flexible start-up model.
【Product Structure】
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. Generally used in the grinding of ores with finer fineness.

【Successful case】
In the process of Tungsten concentrates original production, the owner adopted grid type ball mill method in two stage grinding process to achieve great capacity. After a period, the client found the production didn’t reach the standard, and the equipment had a serious consumption, so the client adopted Xinhai wet overflow ball mill. The pulp of Xinhai wet overflow ball mill overflow automatically, without forced discharge, which reduces the equipment wear and energy consumption, the discharging particle size is small, the qualified rate of grind size is improved, at the same time costs is under control.
