Crushing is the process of ...

calculations define the efficiency of a fine stage-crush ball mill circuit as 1.0 to 1.2 depending on ball mill feed size, and some SABC (SAG/ball mill/pebble crusher) circuits operating with an efficiency of 1.3-1.4 or higher on coarse feed. If the coarse feed size is reduced, the circuit efficiency will approach that of the stage-crush and ball mill circuit. Hence, if the JKDropWeight test ...
