Abstract:To investigate the effect of stirrer discs speed, slurry concentration and grinding media type on energy efficiency of GN8 stirred mill, the energy efficiency was studied by taking stirrer discs speed, slurry concentration and grinding media type as variables. The results show that when the slurry concentration is the same, the energy efficiency with stirrer discs speed of 1 160 r/min is lower than that with stirrer discs speed of 870 r/min, no matter the grinding medium is corundum ball or zirconia ball. When the stirrer discs speed is constant and the corundum ball is taken as grinding media, the energy efficiency with slurry concentration of40% is higher than that with slurry concentration of 60%, while the result is the opposite when the zirconia ball is taken as grinding media. When the stirrer discs speed is constant, the energy efficiency taking the corundum ball as grinding medium is higher that of taking the zirconia ball as grinding medium with slurry concentration of 40%,while the result is the opposite with the slurry concentration of 60%.
