  • Crusher an overview ScienceDirect Topics

    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 CrusherPilanesberg Platinum Mine: Crushing it targets, securing a,Oct 21, 2019· The company’s primary contract requires the company to crush all ROM material from the mine before it is transported to the concentrator. “We operate four 63 t mobile crushing machines around the perimeter of the pit which together has a design capacity of 380 000 tpm,” production manager Walter Eriksen continues.
