How to Improve the Grinding Process of Ball Mill

When materials and shape of the ball mill has been selected, to improve the grinding conditions of the ball mill, is also one of the important ways to reduce the consumption of ball mill liner. What aspects of the ball mill to improve the grinding process design? Reduce the size of the ball mill grinding ball size, ball mill used in the size of the ball with the size of the feed material changes, the greater the size of the feed, requiring the greater the diameter of the ball, the larger the size of the feed and the use of excessive steel The ball not only affects the production efficiency of the ball mill, but also seriously affects the consumption of the ball mill liner and the steel ball. Practice shows that the wear of the ball mill liner increases with the diameter of the ball.
In order to improve the ball mill grinding material size is too large this situation, general condition should use the following measures: 1. Strengthen the ball mill screening operations, and use closed ore. Using a new ball mill crushing and copying broken crusher. Technical transformation of existing crushers.
2. Reasonably ball and ball for ball mill. Reasonable ball and ball, not only improve the grinding efficiency of the ball mill, but also help to reduce the consumption of ball mill liner, an important part is to accurately determine the ball mill ball size.
3. The ball mill speed is the main performance parameters in the grinding process, is the ball mill steel consumption, power consumption, production and grinding products, such as the main indicators of one of the factors, in general, the ball mill cylinder speed Increased production capacity has increased the trend, but the yield is very small, but the lining loss, energy consumption is very serious. According to foreign experts pointed out that the ball mill liner wear at least proportional to the square of the ball mill speed, therefore, we should strictly control the ball mill speed.
Ball mill follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio. It is mainly used for grinding in mining (metallic minerals and non-metallic minerals).
