2016-9-9 CRUSHING Crushing is performed in stages using a combination of jaw, cone and impact crushers and is performed dry. The material is moved by mechanical means with conveyor belts. Sometimes the blasting and crushing fines are washed off the ore, and pumped as a slurry directly to the grinding
دردشة على الإنترنت Read MoreIn crushing, particles are reduced in size to such a level that grinding can be conducted, while grinding allows to achieve the desired liberation size. Besides, the process of comminution can be simple or complicated depending on the nature of the ore and the suitable degree of liberation.
