Ball mill is a kind of pulverizer that is more common in industrial grinding equipment and is also used earlier. It can grind slag, steel slag, coal and other materials, and the quality of the finished product is high. But as the equipment is used for a longer time, there will be a problem of decreased grinding efficiency. What is the reason for this?

1. Speed. The rotational speed is an important parameter that directly affects the grinding efficiency of the ball mill. When the rotational speed is too low, the impact on the material will be small, which will lead to substandard fineness; when the rotational speed is too high, the impact force of the steel ball on the material will increase, but the grinding will not full.
2. Grinding media. The grinding medium in the grinding cylinder of the ball mill is steel balls. If the amount of steel balls added is not appropriate, and the ball diameter and ratio are unreasonable, the grinding efficiency will be reduced. In the grinding process, the larger the ball diameter, the larger the impact wear and the smaller the grinding wear; the smaller the ball diameter, the smaller the impact wear and the larger the grinding wear. When the ball diameter is too large, the number of loads in the cylinder decreases, the overall grinding area becomes smaller, and the wear of the liner and the consumption of the ball will increase. If the ball diameter is too small, the buffering effect of the material will increase, and the impact grinding effect will be weakened;
3. Wear-resistant lining. Ball mill liners not only reduce barrel damage, but also transfer energy to the grinding media. Choosing a high-quality wear-resistant liner can reduce barrel damage and improve grinding efficiency.
4. Material level. If the material level is too high, the ball mill will be blocked, and if the material level is too low, the grinding will be insufficient, so effective monitoring of the material level is very important.
During the use of the ball mill, if the above four aspects are paid attention to and adjusted in time, the improper wear and tear of the mill during use can be avoided, thereby improving the service life of the equipment.
