Online servicesThe power needed to operate a rod mill could exceed 30 of the power used in a ball mill. When they are worn rods must not stretch but break in rather small pieces so that they can exit the mill. The energy consumed by rod mills could be from 10 to 30 higher than the energy consumed by bar mills and this is for comparable performance.
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter Figure 8.11.
