Ball mill is a common type of pulverizer in industrial grinding equipment, and it is also an earlier type of pulverizer. It can grind slag, steel slag, coal and other materials, and the finished product is of high quality. However, due to the long operation time and large volume, the grinding efficiency will decrease over time. What is the reason?

 

 

1. Speed ​​of rotation. The rotation speed is an important parameter that directly affects the grinding efficiency of the ball mill. When the rotation rate is too low, the impact on the material is small, which will cause the fineness to not meet the standard, thus affecting the grinding efficiency; when the rotation rate is too high, the impact energy of the steel ball increases, but the cycle The number of times has dropped, which will also affect the grinding efficiency;

 

2. Grinding medium. As the main grinding medium of the ball mill, steel balls should not only control the amount of steel balls but also control their ratio. If the amount of steel balls added is inappropriate, 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 is reduced, the grinding area of ​​the ball charge is small, 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. The liner of the ball mill not only reduces the damage to the cylinder, but also transfers energy to the grinding media. Choosing a high-quality wear-resistant liner can reduce barrel damage and improve grinding efficiency.

 

4. Material bed. Xinxiang Great Wall mechanical pulverizer manufacturer reminds everyone that if the material level affects the filling rate, it will affect the grinding effect of the ball mill.

 

In addition, the grinding efficiency can be effectively improved by improving the rotation rate of the ball mill, the ratio of grinding media steel balls, the material of the lining plate, and the height of the material bed.
