The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. the quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill.

Ball mill working principle and main part

Ball mills market: overview. a ball mill is typically a grinder which is used for grinding or mixing materials into extremely fine particle or powder. it is used in paints, ceramics, mineral dressing processes, laser sintering, and pyrotechnics. a ball mill works on the principle of impact; where the grinding media is the balls, which may be impact crusher.

Impact mills use revolving hammers to strike incoming particles and to break or fling them against the machine case. in jet mills, particles strike each other as they are transported in a stream of air or steam. for the initial reduction of large materials, a rotating drum propels the feed into the air where the pieces strike each other and impact crusher.Generally, filling the mill by balls must not exceed 30–35 of its volume. the productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. the optimum ratio between length l and diameter d, l: d, is usually accepted in the range 1.56–1.64.
