Pebble mills should always be of the grate discharge type. The energy that can be converted in a mill depends on the total weight of the grinding charge. Consequently, pebble mills convert less power per mill volume unit than rod and ball mills. High quality steel rods and balls are a considerable part of the operating costs.

1. Introduction. High energy ball milling (HEBM) is known as an economic, simple and yet powerful method for the production of nanostructured and amorphous materials [1].The prolonged milling of powder mixtures, results in the formation of supersaturated solid solution, nonequilibrium intermetallic compounds as well as the formation of silicides, nitrides, stable or unstable carbides [2].

A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at fullscale capacity, during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages:

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

A ball mill is a type of grinder used to grind or blend 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.

According to Swart et al. [9], ball mills are mostly used because of their very high size reduction ratio, although they have a very low energy efficiency of about 20%. According to Conger et al. [10], many factors affecting ball mill efficiency include mill design, liner design, mill speed, charge ratio, and grinding media properties.
