  • Energy consumption in fine crushing and dry rod grinding

    Energy consumption in fine crushing and dry rod grinding

    May 01, 1992 Fine crushing and rod grinding have been investigated using a laboratory-scale jaw crusher and a rod mill. The net energy consumption in both crushing and grinding was evaluated from torque measurements. An empirical relationship was established between energy consumption, particle size and operating parameters. When the mill feed size is reduced, through fine crushing, to about
