Research on Selective Grinding of Yunnan Low-Grade Phosphate Rock

Abstract:

In view of the mid-low grade phosphate rock somewhere in Yunnan province, first of all study the mechanical properties of ore, on the basis of which combine Duanshi semi diameter theory formula and crushing statistic mechanics, optimized from diameters, shapes and proportion of the grinding medias, increasing the grinding selectivity only to get selective optimization scheme, finally proved by practice, after changing the media system, on the basis of original mill processing capacity increased by 19.54%, the average steel consumption reduced more than 10%, the particle size of grinding product is easy to process, having an obvious energy saving effect.
