    Large pieces of any ingredient in a feed formula result in weak spots in the pellet, especially if these are fibrous or bony. Grinding also increases the total surface area of a given weight of feed, thereby allowing more space for steam condensation during the conditioning process. The second equipment was measured during a maintenance stop. It was a ball mill installed in a bauxite processing plant. The third equipment was a SAG mill with 32 (9.75 m) diameter, installed in a gold and copper plant. The measurements in the SAG mill were conducted after a grind out.

    Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009. Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary involve grinding). With Lloyd s ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd s research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.

    A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption. Mill spring is a defect in which the rolled sheet is thicker than the required thickness because, the rolls have got deflected by high rolling forces. Elastic deformation of the mill takes place. If stiffer rolls are used, namely roll material of high stiffness or elastic constant, then mill spring can be avoided.
