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/surface.

This is the operation carried out on presses and consists of cutting the outside contour of a stamping. Production of sheet-metal blanks of flat shapes requires a single-action press equipped with tools comprising a punch, a corresponding die, stripper to keep the sheet from following the punch on its upstroke and means for aligning the sheet or strip of material and for spacing successive cuts.
