Crushing Vs Grinding Minerallurgy
Crushing is performed in several stages, reduction ratios are ranging from three to six in each stage. The reduction ratio in grinding can up to 100, therefore it consumes a considerable amount of energy. Therefore, the optimization of grinding operation is very important. Energy. Both crushing and grinding require energy to reduce the ore size.
