HENGIN can provide Φ 2 - Φ 7.9m Ball Mill Liner and Φ 2 - Φ 5m Rod Mill Liner which is made of CrMo alloy steel and high chromium cast iron. It can be customized design and manufacture for ball mill and rod mill liner.
■ Ball Mill Liner Design
According to the parameters of grinding mineral, such as feed particle size, mineral hardness and processing capacity, the paper designs the waveform structure and waveform quantity of the lining plate, and verifies them with DEM software, so that the design parameters of the liner structure are more accurate.
