conventional crushing and grinding circuits (crusher-rod-ball mill or crusher-ball mill). By the 1970s, the application of conventional tended to be limited to relatively low capacities. circuits The majority of modern grinding circuits include a SAG mill, a ball mill and/or a combination thereof. The use of Bond
The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the spe- cific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scale-up of a rocking ball mill, and the optimum design and
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
