Primary Comminution Equipment for Open-pit Mines

Open-pit mining is surface mining in which huge portions of earth are dug from the surface to extract the desired mineral within them. During the mining process, the land face is scraped away by explosives and digging creating a deeper and deeper pit until the mining is complete.

Open-pit mines are seeking high throughput and significant operational efficiencies to remain competitive with higher grade and lower labor cost operations around the world.

In a Canadian open-pit mines, the primary comminution equipment consists of four jaw crushers and one grinding lines(include five mtw roller mill which integrated air separation unit).

Mobile Crushing and Screening Solution for Opencast coal mine

Crushing and grinding together are responsible for the consumption of approximately 3% of all electric power generated in the world mainly due to the low level of energy efficiency of comminution processes (Fuerstenau 1992). Thus, there is a valuable opportunity to save energy consumption and reduce operational costs in mining operations around the world through the optimization of comminution processes.
