Hence, a mill is a piece of equipment used to grind ores. Its major purpose is to perform the grinding and blending of rocks and ores to release any freegold that is contained within them. At major mines, the mill was the critical equipment that was required to process the ores that were extracted from deep underground.

erroneously taught that a homogeneous material's work index is constant. The reality is that work index is only constant for materials that have the empirical exponent of ½ when a series of work index determinations are conducted at a variety of product sizes. For example, the ball mill work index measured on a sample of ore

One contribution to minimise the increase is to use more efficient comminution equipment. Verticalrollermills (VRM) are an energyefficient alternative to conventional grinding technology. One reason is the dry inbed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.

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.
