Efficiency Of Rod Mill

rod mill - an overview | sciencedirect topics,the 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..rod mills - 911 metallurgist,rod mills use low cost grinding media. less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media. this also results in.what is a rod mill? (with picture) - infobloom,the rod mill is generally more efficient than the ball mill due to its more effective cascading action and the greater bearing surface offered by the rods. this means it can operate at lower speeds and with less grinding agents and producing less undesirable slimes byproduct..7 differences between ball mill and rod mill - xinhai,selecting the ball mill and rod mill according to the granularity and effect of the finished product the processing capacity of rod mill is greater than that of the ball mill when the product size is 1-3mm in the coarse grinding process, while the grinding effect of ball mill is greater than that of the rod mill when the product size is less than 0.5mm in the fine grinding process..
