  • 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 wearresistant plate/surfaceThe primarily used equipment in crushing arejaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant Crushing is a dry process whereas grinding is generally performed wet and hence is more energyMineral processing Wikipedia

  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sinteringIt works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotatiPrimary grinding – Lime is often added into the semiautogenous (SAG) mill together with the ore feed and process water Sulfide minerals are, by nature, acid to varying degrees causing the milled pulp to have a pH ranging from 4 to 8 depending on the sulphide and gangue mineral composition of the oreLime use and functionality in sulphide mineral flotation
