Sep 01, 2019 A series of batch grinding tests were carried out using four different lifter (lifter I to IV) geometries and the rate of breakage was determined for each condition. Natural feed size of a top size 9.5 mm was ground in a = 0.32 m test mill (J b:40%, w/w: 68%, N c: 55, 65, 75 and 85%). The torque was recorded against the wear measurement of
[email protected]Sep 01, 2016 According to the ball mill survey database presented in Section 4, the volume-based residence time of slurry in an overflow ball mill should be greater than 2 min for a less than 5.9 m diameter ball mill, and 1 min for a larger than 5.9 m ball mill
