In mineral processing or metallurgy, the first stage of comminution iscrushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition forcrushingrocks. In principle, compressioncrushingis used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less …
Apr 01, 2020· (1)Crushingand Grinding of theOre. The ores occur in nature as huge lumps. They are broken to small pieces with the help of crushers or grinders. These pieces are then reduced to fine powder with the help of a ball mill or stamp mill. Thisprocessis called pulverisation. (2) Concentration ofOreorOreBenefaction
Get PriceCrushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so theore must be crushed to reduce the maximum particle size. Crushed ore is divided into various …
