Working Principle & Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the
Ball mills of greater length are termed “tube mills,” and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as “pebble mills.’’ In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 um.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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. A ball mill consists of a hollow cylindrical shell rotati

Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle, but on a much larger scale.
Whereas particles break more easily when larger grinding ball resp. rod diameters are used, smaller diameters lead to a substantially higher final fineness. The motor of the drum mill incorporates a solid-state controller with internal overload protection which is
After milling for 15 h, the mean powder size in the case of using 16 mm diameter balls is finer than that for the 9.6 mm diameter balls, which means that the larger balls give more impact force to the aluminum foil than do the smaller ball,, . The weight of a steel ball of diameter 16 mm is about five times greater than that of a 9.6 mm ball
