Our small-scale miners 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
3.1 ball mills are devices, used in mineral dressing processes and other operations (paints, pyrotechnics, ceramics, and selective laser sintering, for the grinding of materials. This device is used in DOVE Semi-Stationary Hard Rock plants to grind the ore until the liberation size of valuable minerals is reached.
