Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼" to 1.5". The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.
The liners are from 50 to 65 mm thick (2″ to 2.5″) with the waves from 60 to 75 mm (2.5″ to 3″) above the liners. The replaceable lifter bar design made of either metal or rubber in about the same design proportions can be used. There could be a loss in power with rubber particularly if the mill speed is faster than about 72% of ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
Ball Mill Sole Plate. This crown should be between .002″ and . 003″, per foot of length of sole plate. For example, if the sole plate is about 8′ long, the crown should be between .016″ and .024″. Ball Mill Sole Plate. After all shimming is completed, the sole plate and bases should be grouted in position.
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm. dk = the P90 or fineness of the finished product in microns (um)with this the finished product is ...
