Prolonged exposure to elevated noise levels during operations may affect hearing. A greater hazard, in most cases, is the exposure to the dust/fumes from the material or paint/coatings being ground. Most of the dust generated during grinding is from the base material being ground and the potential hazard from this exposure must be evaluated.

High Chrome Grinding Media: They are often used in the mining industry to grind up rock, cement, and other materials that have been extracted from the ore. High-chrome grinding media is used in mining because it has higher hardness, good surface finish, low wear rate, and steady milling conditions.


The frictional heat generated by the grinding media tends to soften the sample creating a "caking" effect shielding the underlying mass from further comminution. The recommended starting point is to evaluate a 1 to 2-1/2 wt.% additive-to-sample weight (e.g. 0.1 to 0.25gm additive to 10gm sample).
