Classifying efficiency plays an important role in grinding efficiency. High classifying efficiency means that those qualified grains can be discharged timely and efficiently,while low classifying efficiency means that most qualified grains are not discharged and sent to the ball mill for re-grinding, which is easy to cause over-grinding and ...Moreover,the efficiency of crushing is obviously higher than that of grinding, and the energy consumption of crushing is low, which is about 12%~25% of the grinding. 3. …

Through the long period operation, ball mill meets the problem of grinding efficiency descending. It impacts the normal operation of processing plant, and also causes economic losses.the efficiency of grinding Extensive investigation of the relation between the energy supplied to a mill and the size reduction achieved has been carried out. The efficiency of the process reflected by such a relation is of small importance in pharmacy because the applications are limited.
