Crushing and Screening for Mineral Processing Success

When looking at overall crushing circuit design, having the correct number of crushing stages also helps minimize fines production. A typical crushing circuit will generate a reduction ration between 5:1 and 7:1 for maximum efficiency. For example, to generate a 10mm particle, you’ll want to feed the crusher particles between 50 and 70mm.
