materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. ball mill consists of a hollow cylindrical shell rotating about its axis. the axis of the shell may be either horizontal or at a small angle to the shell-supported ball mills are becoming the mills of choice over those with trunnion bearings. depending on the size of the mill, there are two, four or six sliding shoes per bearing assembly. the expected bearing load determines whether hydrostatically or hydrodynamically lubricated bearing shoes are used. sturdy and reliable: mill bearing
