Online ConsultingThe 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.
Online ConsultingJan 01, 2016nbsp018332Power required for the cylindrical section of Ball Mill overflow type. In the case of overflow mills, the slurry reduces frictional forces between the solids and the inside of the mill. Thus, the power required for overflow mills would be less than for grate discharge mills.
