Ball Mill Grinding Efficiency Theory

The total feed to the ballmill was therefore 11.54 T. per hr. or 179 per cent, of the original feed. It was evident that the ballmill was greatly underloaded in this test, but so much trouble developed in the classifier, due to the tendency of the sands to slip down the slopes, that a more rapid feed was not attempted at this time.

    Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill
