Optimizing heat treatment and wear resistance of high …
The properties of the metallic matrix are fundamental to obtain high wear resistance. The example shown in Fig. 1 refers to cast irons tested as grinding balls in a ball mill [2].Because of different heat treatments one sample has high hardness martensitic matrix while the other presents a low hardness austenitic matrix.

Research of iron ore grinding in a vertical-roller-mill
One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.

Hammermill Crushers
Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.
