1. Add a fine crusher before the mill;
2. Improve the grinding system and improve the grinding efficiency;
3. Add a high-efficiency classifier.
Any of the above three methods can greatly increase the output of the ball mill. Of course, if the factory conditions permit, the above three methods are used together, and the effect is the most ideal. This is also the general trend of domestic and international grinding system design in recent years.
The relationship between the three: pre-grinding is the premise, the selection of powder after grinding is guaranteed, the transformation within the mill is fundamental. The fine crushing before grinding makes the particle size of the grinding material greatly reduced, thereby reducing the load of the grinding system; the most direct benefit is that the fine powder of the finished product is selected in the maximum amount in time, reducing the powder return rate of the finished cement product and reducing Mill load; and the internal modification of the mill, which is the improvement of the grinding system, is the most fundamental solution.
The particle size of the milled material is reduced, and the efficiency of the powder selection is improved. If the efficiency of the grinding system is low, it affects not only the output of the mill but also the quality.
