Our small-scale miner’s 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. particles are broken in the toe of the mill when caught in the collisions between the grinding media themselves and the grinding media and the mill.Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late ’s. the basic construction of a ball mill is a cylindrical container with journals at its axis. the cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and the cylinder is put into rotation via an external drive causing the media to roll, slide and.
