Wet Ball Mill

Introduction of wet ball mill

Mill is essential and widely used equipment for raw material crushing. Wet ball mill is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control).

The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. Bearing adopts oil lubrication system, thus help bearing internal dirt cleaning and reduce the bearing attrition during normal operation.wet ball mill

Advantages of wet ball mill

1. It adopts groove circular plate, which increases connecting area, strengthens the grinding function, and reduces the powe, energy saving should be more than 20%.

2. Wide range of materials processing, high production capacity, unit power consumption is low.

3. Wet ball mill adopts antifriction bearing instead of sliding bearings, which reduces friction and save consumption.

4. Grinding process can be used more sections, forced discharge, velocity faster

5. Large ball mills are equipped with slow transmission device, easily to maintain and start.

6.  It adopts the whole frame, convenient for civil construction and device installation.

Working principle of wet ball mill

Wet grinding mill is a ball mill with a single bin peripheral discharge device. Materials go into the cylinder body from the feeding end of the hollow shaft. The cylinder body, with a grinding medium (steel ball), is driven by a main motor, a speed reducer and a gear device.

Materials are put in cylinder through the feed opening and then thoroughly grinded, because the falling course of iron balls and ores can produce huge falling impact and autogenous grinding.

The continuous feeding of ores can create considerable pressure to make ores move from feed opening toward discharge opening. Finally, acceptable particles are discharged from the discharge opening. Acceptable ore particles are carried away by water by wet mill, or by air by dry mill.

The discharge opening is equipped with a discharge grate, and the ore pulp horizon of discharge opening is low. These two factors prevent ores from being overly grinded, and iron balls from being dismissed. Under same circumstance, the processing capacity of wet ball mill is bigger. Rolling bearings contribute enormous energy saving.
