The wet ball mill grinding is a key link in the separation operation, which will directly affect the concentrate grade, recovery rate and production capacity of the beneficiation products of the concentrator. Grinding operations are still the main growth point for the economic benefits of the concentrator. If the economic benefits of the entire concentrator are to be guaranteed, the grinding efficiency of the wet ball mill should not be affected.

During the grinding operation, the grinding efficiency of the wet ball mill is mainly reflected in the movement form of the steel ball in the cylinder, the speed of rotation, the supplement of the steel ball, the level of the material and the selection of the liner.

1. The movement form of the steel ball in the cylinder
To a certain extent, the motion state of the steel balls of the wet ball mill in the cylinder is one of the factors that affect the grinding efficiency of the ball mill. Under normal circumstances, the working environment of the ball mill can be divided into four forms, namely movement in the surrounding and dropping movement area, movement in the dropping movement area, movement in the area around the center and movement in the blank area.

2. Rotation rate of wet ball mill
The speed of rotation is a main working parameter of the ball mill operation, and this parameter is the main factor that directly affects the grinding efficiency. During the operation of the ball mill, we need to consider the speed of the ball mill, as well as the filling rate. There is a proportional relationship between the two. Only when a certain filling rate is maintained, the speed of rotation needs to be considered.

3. Wet ball mill steel ball refilling
The supply of steel balls is also the main factor affecting its grinding efficiency. If the amount of steel balls fed is improper, the grinding efficiency will be reduced. During production, if the manual ball addition is not well controlled, the steel balls will accumulate, which will cause the ball mill to jam, which will cause the ball mill to wear and reduce the productivity.

4. Material level of wet ball mill
The material level of the wet ball mill mainly affects its filling (adding ball) rate. If the material level is too high, it will cause the ball mill to block the material and reduce its grinding efficiency.

5. Selection of lining board for wet ball mill
The main purpose is to reduce the wear of the ball mill barrel, and the other is to transfer energy to the grinding medium. The main factor that affects the grinding efficiency of the ball mill is determined by the working surface of the ball mill liner. In the grinding operation, when the selected ball mill liner material cannot effectively play the role of wear resistance, its wear rate is faster, the barrel damage rate is high, and the grinding efficiency will be affected.
