Double helical feeders used in closedcircuit with classifiers; Spout feeders preferred when using a closedcircuit with classifying cyclones. Cyclones are typically installed above the mill and thus the cyclone underflow is fed to the mill by gravity. Discharge System. One exit unit; Exit about 5 – 110 cm lower than the center line of the overflow mill.

which can either be open circuit or closed circuit with an air classifier. Selection of right mill for the specified duty is the most critical for circuit design, since it has the highest capital and operating costs. Bond method has been used for ball mill selection in both mineral and cement industry for 50 years.

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 rotating about its axis. The axis of the shell .
