the gravity-induced low speed stirred milling technology, commonly referred to as tower mills, are widely used for fine grinding due to their high energy efficiency compared to conventional tumbling mills. moreover, the lower operating cost, shorter installation period and simpler operating strategy make it attractive for many mines. researchers have attempted to develop an ore vertimill is typically arranged in closed circuit and fed by the cyclone underflow. the motor power turns the vertimill screw at constant speed to stir the grinding balls and slurry. As the particles are ground, they rise to the top of the mill and overflow into the separating tank.
the attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines. the vertimill energy savings range from 30% to greater than 50% compared with traditional ball mills and the smd energy savings are far greater than 50% of ball mill energy in fine the attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines. vertimill energy savings can range from 30% to greater than 50% compared with traditional mills, and the smd energy savings can be far greater than 50% of ball mill energy in fine grinds.
vertimill grinding ball effect. ball size effect on final product size in grinding mill calculation of energy required for grinding in a ball mill the grindingproduct size in a bond ball mill which is given by the aperture size which passes of the grinding product as a function of the aperture size of the test screen Pk can be.the improved grinding energy efficiency of the vertimill is due largely to the effect of the vertical arrangement. horizontal ball mill relies on the tumbling action of the slurry and media for both impact breakage and attrition grinding. however, impact energy is generally not as efficient as attrition grinding since much of the impact
