查询词典 cogging mill

The paper reports the results of investigation for the operation condition of the ball-mill coal-pulverizing system of 100MW and larger power station. Based on the analysis of the ball-mill mechanism, the problem was found that the energy consumption on empty load of ball mill is more than 90% of the total energy consumption and the small iron balls that has lost mill ability and the iron component in the coal increased the mill s energy consumption. Thus automatic ball filter equipment was developed and in...
