Abstract:

The importance of the grinding operation effection is self-evident to the work of the production and business for a concentrating mill.So how to use a simple,efficient and practical feasible method to improve grinding efficiency is always the dressing worker’s research topic.At present,there are several standard parameters to test the run state of the mill:the grinding machine utilization,the energy consumption of grinding,the grinding cost,etc.Based on a lot of testing and research of ball mill running state,we optimize mill internal structure,adjust the internal ball size distribution,to adapt to the changes in the grinding load.So with less investment,grinding performance is improved.

Key words: Internal structure of ball mill, Ball size distribution, Grinding efficiency, Intrinsic parameters
