Methods to Improve the Efficiency of Ball Mill

How to improve the efficiency of ball mill? Here Hongxing Machinery gives you some suggestions:

1. Increase the Effective Volume.

Increase the effective volume can improve its productivity. The thick lining board and heavy weight not only improves the power consumption, but also reduces the cylinder volume and the production efficiency of ball mill. To choose magnetic lining can increase the effective volume of the cylinder at the same time of reducing the weight and power consumption.

2. Increase the Rate of Filling and Turning.

The processing capacity of ball mill increases with the filling rate of the steel ball. Improving the filling rate increases the chance of steel ball grinding and the self-grinding effect of ores. The ball mill load is the largest when the steel ball's filling rate reaches 45%, and the load will decline dramatically if the filling rate exceeds 45%.

3. Change the Shape of Grinding Medium.

We can choose oval ball medium instead of current ball medium, and compared with ball medium, the oval ball has advantages as follows:

1. Oval ball is 62% heavier than ball with the same diameter, so it has a stronger impact force and a stronger crushing capacity.

2. The line contact of oval ball replaces the spot contact of ball, having a contact area 4 times larger than the latter. So it have a better grinding and screening effect to materials and no over grinding phenomenon. Its final products are even in granularity.

3. The ball surface area of Oval ball increases by 8% compared with ball with the same diameter, increasing the contact surface of the steel ball medium and material and improving the grinding ability;

4. The line contact of oval ball replaces the spot contact of ball, reducing the lining board abrasion from steel ball medium and the impact of the mill lining board, thereby reducing ball medium and the mill wear and prolonging its service life;
