Rod And Ball Mill weddingfilmart.de
Rod And Ball Mill. Ball Mills vs Rod Mills When the mill is rotated without feed or with very fine feed the rods are in parallel alignment and in contact with one another for their full length New feed entering at one end of the mill causes the rod charge to spread at that end This produces a series of wedge shaped slots tapering toward the discharge end
Ball Mills an overview ScienceDirect Topics
Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).
Optimum choice of the makeup ball sizes for maximum
01092013· 1. Introduction. The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of largesize particles, whereas smaller balls are more effective for the breakage of fine particles.
Industrial Ball Mills for Sale 911Metallurgist
Industrial Ball Mills use horizontal rotating cylinders that contain the grinding media and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the “toe” of the mill when the force of gravity exceeds friction and centrifugal forces.
