Ball Mills Mine
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced Various classifiers, such as screens, spiral
Why use Different Size Balls in a Mill
In test 3, in which the grid was used to segregate the different sizes of balls, a further advantage of about 4 percent in efficiency is shown The conical mill in test 4 increased the efficiency to 58 percent more than in test 1 The efficiency with the long (6foot) conical mill was about the same as with the short (3foot) one
