Aiming at the problem that an unreasonable ball ratio and the low degree of grinding fineness resulted by too much big balls in a phosphate fertilizer plant of Yunnan can not meet the requirements of phosphoric acid production, the grain size composition of ore was analyzed. According to the grain size composition of ore, using the accurate costume complement method proposed by Duan Xixiang professor of Kunming University of Science and Technology, a scheme of precise ball solution for mill to the phosphate fertilizer plant, and a partial big scheme and a partial small scheme were put forward, which compared with the pack ball scheme in the factory. Experimental study results show that the accurate pack ball schemes is best, which can increase the production capacity of ball mill by 14.44%. Based on the new scheme of the grain size characteristics curve, a plan of ball load and addition is given, which can make the steel ball load composition always keep the level of recommended initial installation approximately.
