Fine Grinding With Impact Mills Chemical Engineering

Mechanical impact grinding can be used on materials with a Mohs hardness of up to 34 (see Table 1). But even small amounts of harder components in the feed material can lead to an uneconomical degree of wear. When grinding natural gypsum — which is actually soft — a few percent of quartz in the feed will make it necessary to exchange the wear plates in the mill frequently. The same or
