The grading of steel balls in bentonite milling machines is to achieve impact and grinding of materials with different particle sizes to improve grinding efficiency. Therefore, the gradation of steel balls in bentonite milling machines is very important, and the general gradation range is 25% ~ 35% %, but most of the intermediate grades in practical applications are 28% to 32%.

The gradation ratio of bentonite milling machine steel balls in common economical operating conditions: steel ball diameter mmΦ100Φ80Φ60Φ40Φ20 mass/total loading 7.5% 6.9% 33.5% 30.1% 22 Note: When the easy grinding performance of the material is poor, or the grinding requirements are relatively fine , the fill rate of a bin should be >28%.

The temperature of the material entering the bentonite milling machine is too high. Generally, when the temperature of the material entering the bentonite milling machine is too high, it is easy to reduce the grinding efficiency. When the temperature of the bentonite milling machine exceeds 100 °C, an air film isolated from each other on the surface of the small particles of the material will be damaged. damage, causing adhesion.
