The model for optimal charge in the ball mill J Min Met 43 A (2007) 23 For each narrow size distribution of quartz there exists a ball diameter which gives the highest grinding rate, and that is, in fact, the optimal diameter of ball for the given quartz size Since ball charge of different diameters …

sizes of ball 97 C2 Reduced particle size and selection functions for the single sizes of balls 97 D1 Breakage function obtained for the single ball sizes 98 D2 Data used to assess size distributions normalization 99 E1 Predicted selection function parameters in the different ball intervals used 100

volume of mill, the rate of ball-on-ball contacts per unit time increases with the increase in ball diameter, because the number of balls in the mill increases as 1/d3 Thus, the rates of breakage of smaller sizes are higher for smaller ball diameters The relation with T a and ball diameter in a 06 m diameter mill were given as aT α 1/d 9

Oct 12, 2017 · The ball charge of a SAG mill is about 29% to 30% By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness The internal machinery of ball mill grinds the raw material into the powder-like material, And if extreme fineness and refinery are required then rotation go on continue

of the liners of the mill for a complete revolution (1) CS = 43305 √Mill Diameter where CS is the theoretical critical speed of rotation, and is the mill speed, rpm; Mill diameter is the nominal inside diameter of the mill, m Since we actually need the particles to come off the inside diameter of the mill to be processed, the typical mill

Another challenge is in obtaining very fine particle sizes Traditional vertical mills and ball mills are often limited to a finished particle size of approximately 5 microns, which can be achieved only with careful attention to media size

and collecting data requires a lot of effort and cost On the other hand, with the recent improvements in Design Method of Ball Mill by Discrete Element Method 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
