Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate ...

Open or Closed Circuit Crushing

“Stage-crushing,” as we use the term here, applies to open-circuit reduction in a flow line comprising two or more crushing stages, with scalping between each stage, but without close-circuiting any stage upon itself; except, perhaps, the final one.
