Ball mill design is rather simple. This grinding equipment is a drum filled with metal or cast iron balls (grinding media). It is used mostly for production of bulk construction materials, paints, pyrotechnical devices, ceramics and in other industries. The ball mill patent was sealed more than 180 years ago.
The ball mill rotates on its horizontal axis so that the media cascades causing size reduction by impact and sheer forces. Feed material size for ball mills is usually less than 1 in., and they are effective to produce a particle size range of 5-500µ, …
A trunnion seal assembly for joining a stationary inlet/outlet box of a ball tube mill to a rotational interior of the ball tube mill includes an outer ring component configured to be mounted to an outer wall of the stationary inlet/outlet box. An inner ring component is joined to the outer ring component substantially concentrically with the outer ring component.
The Sag mill uses lifting plates along the interior of the drum, which lift material throughout the rotations, causing them to fall onto one another to promote crushing. A ball mill has many steel or porcelain balls put in a drum to grind the feed between balls and between the balls and drum inner wall as the drum rotates.
A ball mill for treating and washing used casting sand has a drum that includes an interior and exterior wall. The space between these interior and exterior walls form an intermediate chamber.

The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
The drum type ball mills are used for grinding hard-ground materials (in ceramic, tool-making and other industries). The mill is a cylindrical drum installed on bearings and driven by a motor through a gearbox. The material is charged and discharged through a latch. Capacity of mills is determined by their volume (1 to 7 m3) and duration of ...
The drum size was chosen in comparable with a laboratory scale ball mill (Tuzcu and Rajamani, 2011). Periodic boundary conditions were applied in the horizontal direction to avoid wall effect. The drum was partially filled with particles and rotated at a constant speed 60 rpm.
