Working principle. Fed into the mill through one or both bearing trunnions, the material is ground by impact and friction from the balls. The ground product is discharged from the mill through discharge slots provided in the mill tube, through a discharge wall or through the end trunnion. 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.

Cylindrical Ball Mills. The only cylindrical ball mills in common use are those of the grate discharge type, the most important being the Marcy and the Allis-Chalmers mills. Fig. 10 illustrates the construction of the Marcy Ball Mill. The cylindrical shell and the feed and discharge heads are made of cast semi-steel. The vertical ball mill is used for the processing of high-viscous pre-mixed pastes, like chocolate, compound, crèmes, nut- and seed-paste. The continuous design vertical ball mill can be used in a 1 – 3 stage refining system, with 1 – 3 ball mills in a sequential row after the pre-mixer.
