Grinding Ball Selection And Ratio
013 As the size reduction ratio increases, the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of a 50.8 m.4 mm ball mix at a ratio was found to be the optimum mix. get price is known as the size reduction ratio and is used to evaluate the relative performance of different types of equipment. coarse grinding has rrs below whereas in fine grinding, ratios can exceed rittingers law states that the energy required for size reduction is proportional to thethe result size of crushing down to mm, while grinding size range from hundreds to tens microns or microns. reduction ratio. 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.
