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 wearresistant plate/surface.
of smooth operation were conducted with mill product samples taken every 15 min to make composites. Feed samples were taken from two of the three feed belts for that mill at the end of the hour, after stoppage of the circuit. Feed samples were used to measure grindability for autogenous grinding using SPI and found to be very soft (4 to 13 min.).
