Sylvine Grinding Performance Comparison between Vertical Stirred Mill and Ball Mill

As a fine grinding equipment with innovative structure and high efficiency,vertical stirred mill is used more and more in second stage grinding and regrinding process. In this paper, sylvine grinding tests were carried out with vertical stirred mill and ball mill,based on the analysis of work principle of those two kinds of grinding equipments. Sylvine grinding performance comparison between those two types of mill was made. The test result showed that at the same feed particle size,the reduction of-2 + 0. 18 mm particle size by stirred vertical mill was more evident than that by ball mill,which indicates the advantage of vertical stirred mill for fine mineral particle grinding. Meanwhile,the energy consumption of vertical stirred mill was 20. 34% lower than that of ball mill,which proves high efficiency of vertical stirred mill for sylvine grinding.
