FAM designed crushers are used for crushing minerals, raw materials and other bulk commodities. The types of crushing machines are distinguished by their working principles: by pressure, impact, hammer, or shear. In contrast to mills, crushers process the feed materials into grain sizes from coarse to medium granulation.
