Theoretical capacity of crushing rolls in tons/hr is given by (where, V = peripheral velocity, m/sec. W = width of rolls, m Dr = distance between rolls ? = density of material to be crushed, kg/m3 here, V =?ND where, N = speed of the rolls in rotation per second (rps) D = diameter of rolls, m) ?

A. 3.6 W.Dr.?

B. 3.6 V.W.Dr.?

C. 3.6 V.W. ?

D. 3.6 V.W.Dr/?
