reduction ratio for grinding mill Description

Mill (grinding) - Wikipedia

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

For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultra-fine powders, are normally attained by several stages using diverse crushing and grinding machines. A good example of this is the overall milling of wheat grain
