The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter ( Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
WhatsApp The mill is designed to handle a total ball charge of t at loading with a percentage filling of % in both the chambers. Both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in Ist chamber and 172 t in the IInd chamber.

01/03/2014· Though, there are small differences in the mill speed (N: versus ) and ball load (J: versus ), in our opinion the main factor is the ball size distribution: a single size ball charge versus a ball charge made up of balls of three different sizes. The void space in the ball charge, the relative movement of different layers of balls and the type of breakage events generated are ...
