BENEFITS. Prater Fine Grinders (M Series Mills) are designed to grind dry, free-flowing material as fine as 400 mesh (37 microns) with a very tight distribution of particle size. The highly efficient design allows for ease of access to all internals and is well suited for heat-sensitive materials such as resins and sugar.

There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and grind it at the same time by sweeping hot air through the mill. As an alternative, water can be added to the material and it can be ground wet; this solution is suitable for hammer mill operation but not for jet mills.

In dry grinding it was a new experience to see the capacity curves and power curves of each series sloping in opposite directions instead of running nearly parallel, as they did in wet grinding. (See fig.1.) The dissimilarity of the power curves in wet and dry grinding may be examined by considering the amount of ore and water in the mill.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
