    Fine or Secondary Crushing. We distinguish between fine crushing and finest crushing. Narrow grain-size ranges or highly abrasive products are grinded by two-roller mills by pressure grinding. Softer and medium hard products with lower wear rate are crushed by means of dynamic systems such as hammer mills. Grinding characteristics and requested grain distribution define the system. To avoid
