Ball Mill Grinding P80 Size The mesh of grinding usually lies between 48 and 200 mesh On account of their size in relation to that of the bubbles particles larger than 48 mesh generally have too great a tendency to drop out of the froth and escape in the tailing while the lower limit is determined by the fact that grinding finer than 200 mesh is usually too costly to be
