Fine Grinding - an overview | ScienceDirect Topics

The general guidelines for high performance grinding require a 40–60 mesh for rough grinding; a 60–100 mesh for finish grinding; and a 100–320 mesh grain for fine grinding. When selecting a particular grain size one must consider that large grains allow the user to remove material economically but make the material easier to machine by producing longer chips.

Different Approaches to Grinding Abrasive Materials ...

For larger reduction percentages, the roll can be set up in a series from wider gapped rolls to progressively smaller roll sets. This gives a very nice reduction in size, without contamination and minimal fines creation. The drawback to roll crushing is the cost of the parts and the time needed to change out the roll shells. Fine Grinding
