Crusher
Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. 13.3.1.1 Primary Crusher

The secret behind NCM-FINE crushers' efficiency is the unique crushing process. While most other crushers reduce rocks by pushing them by force against metal, NCM-FINE crushers also utilize the rock to crush itself. This so called autogenous crushing action results in lower cost per ton than any other impact crushing method.
