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.
2 Key parameters in crushing. The raw material in a crushing plant is the seed; main and by-products are the meal, the crude oil, the hulls, foreign material and impurities, respectively. The crude oil is usually water degummed in the crushing plant which generates an additional flow, consisting of gums (or lecithin).
