Most dust concerns involved with cast iron grinding will fall under OSHAs total dust limit of 15 mgm3. This permissible exposure limit PEL is a cap on a workers exposure as averaged over an 8-hour shift. The PEL for iron oxide is more strict. Workers are only allowed 10 mgm3 during the course of a shift.

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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either
The Grinding Balls will grind the material into powder size of 20 to 75 micron. In mining operations this will allow for the liberation of gold and other precious metals that are hosted by the rocks. Many types of grinding media are suitable for use in a ball mill each material having its own specific properties specification and advantages.
