The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:
Economic analysis on the process was developed through considering the energy requirements, cost modeling and carbon balance. Mechanical activation on mining residue reduced the particle size, enlarged the surface area, distorted the crystal structure of forsterite, and enhanced the CO 2 sequestration efficiency.

Crushing Energy Efficiency. According to one estimate, the mining industry consumes 12EJ per year of energy – or 3.5% of total final global energy consumption.1 The energy intensity of mining is also predicted to increase over time as deposits that are lower quality, deeper and more difficult to extract are mined.
