When the materials and shapes used in the overflow ball mill have been improved, improving the grinding conditions of the overflow ball mill is also one of the effective ways to reduce the consumption of the lining of the overflow ball mill. So what factors should be considered to improve the grinding process design of the overflow ball mill.

1. Reduce the particle size distribution of the overflow ball mill grinding feeder
Reduce the particle size distribution of the overflow ball mill grinding feeder. The diameter of the steel balls used in the overflow ball mill changes with the particle size distribution of the feeder. The larger the particle size distribution of the feeder, the larger the steel ball diameter is required. If it is too large, The particle size distribution of the feeder and the use of excessively large steel balls not only affect the productivity of the overflow ball mill, but also seriously affect the consumption of the overflow ball mill lining plate and steel balls. Practical activities have shown that the damage to the overflow ball mill lining plate is random. The diameter of steel balls has never been greater. In order to improve the situation that the particle size distribution of the overflow ball mill grinding feeder is too large, it is generally recommended to strengthen the screening operation of the overflow ball mill and use closed-circuit crushing.

2. Appropriately load and refill the overflow ball mill
Use new overflow ball mill crushing and ultra-fine crushing crushers. Carry out equipment modifications to the shared crusher, and appropriately load and replenish balls for the overflow ball mill. Proper ball loading and refilling can not only increase the grinding rate of the overflow ball mill, but also help reduce the consumption of the overflow ball mill liner. The second important step is to accurately confirm the steel ball specifications of the overflow ball mill.

3. Moderately reduce the speed of the overflow ball mill
Moderately reduce the rotation speed of the overflow ball mill. The rotation speed of the overflow ball mill is the main technical parameter in the grinding production process. It is the main influence on the steel consumption, heat consumption, production volume and grinding product process index of the overflow ball mill. One of the factors is that usually, as the head speed of the overflow ball mill increases, the production volume tends to increase, but the frequency of high production is not large, but the jaw plate wear and calorie consumption are very serious. Therefore, we should strictly control Number of revolutions of overflow ball mill.
