Ball mill liners can be customized manganese steel liners or wear-resistant rubber liners according to requirements, which have good wear resistance, long service life and easy maintenance.

working principle

Principle of the 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 a simple structure, higher operation rate, and rolling bearing, the energy conservation is significant.

Generally used in the grinding of ores with finer fineness.

technical parameter

success case

In the original production process of tungsten concentrate, in order to pursue a larger processing capacity, the second-stage grinding process used a grid-type ball mill. It was finally found that the output did not meet the standard, and the equipment was seriously worn out. Therefore, Xinhai's new wet overflow ball mill was used. This new type of ball mill does not require forced ore discharge, and the slurry overflows automatically, which reduces equipment consumption and energy consumption.
