Grinding efficiency, but also improve the energy-saving efficiency of the limestone grinding mill. However, grinding aids for limestone grinding mills should be added in accordance with the national standards. In general cement production process, the amount of grinding aids added should not exceed 1%. The proportion of grinding aids for other materials can be inquired through the national standards.
The gradation ratio of limestone grinding mill 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 limestone grinding mill is too high. Generally, when the temperature of the material entering the limestone grinding mill is too high, it is easy to reduce the grinding efficiency. When the temperature of the limestone grinding mill 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.
