    Effect of speed on the slurry phase grinding and mixing. The mill speed and the resulting change in the solid phase flow have two important consequences for the slurry phase grinding: 1. Higher mill speed leads to greater shear and higher energy dissipation which increases the grinding rates. 2. With increasing speed, the amount of material in the cataracting stream and in the upper part of

  • Wet And Dry Grinding Rod Mill & Rod Coal Water Slurry

    09/05/2019· The rod mill, a tumbling mill characterized by the use of rods as grinding media, is used for grinding ores, coal/coke, and other materials for both wet and dry applications. The rod mill performs best when making products having a top size of 4 mesh to 16 mesh operating in open circuit, or as fine as 35 mesh operating in closed circuit with a screen or other sizing device.
