What factors affect the grinding efficiency of ball mill?

The ball mill is a common type of industrial grinding equipment and is also the earliest applicable type of grinding mill. It can grind a variety of materials such as slag, steel slag, coal, etc., and the finished product is of high quality. However, due to the long running time and large volume, the grinding efficiency will decrease over time. What is the reason for this?

1. Rotation rate. The rotation speed is an important parameter that directly affects the grinding efficiency of the ball mill. When the rotation speed is too low, the impact on the material is small, which will lead to substandard fineness, thus affecting the grinding efficiency; when the rotation speed is too high, the impact energy of the steel ball increases, but the cycle If the number of times decreases, it will also affect the grinding efficiency;


2. Grinding media. As the main grinding medium of the ball mill, steel balls must not only control the amount of steel balls added but also 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. During the grinding process, the larger the ball diameter, the greater the impact wear and the smaller the grinding wear; the smaller the ball diameter, the smaller the impact wear and the greater the grinding wear. When the ball diameter is too large, the number of loads in the barrel is reduced, the grinding area of the ball charge is small, and the wear of the liner and the consumption of the balls 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 plate. The lining of the ball mill can not only reduce damage to the cylinder, but also transfer energy to the grinding media. Choosing high-quality wear-resistant linings can reduce barrel damage and improve grinding efficiency.

4. Material bed. CHAENG Mill 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 and steel balls, the material of the liner, and the height of the material bed.

CHAENG can provide the market with energy-saving, low-consumption, high-yield and high-quality ball mill equipment. Welcome to inquire and purchase!
