Comminution Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes [1] [2] In geology, it occurs naturally during faulting in the upper part of the Earth's crust [3] In industry, it is an important unit operation in mineral processingA hammer mill is guidance for selecting a safe unloading method for materials typically good for grinding softer materials with Mohs hard received in bags, bulk bags, or drums Materials with a low ness ranging from 1 to 5, while a jet mill can grind materials MIE (eg, <10 mJ) require special equipment and operaHammer Milling and Jet Milling Fundamentals | PDF | Mill
