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

• 3.6 V.W.Dr.ρ
• 3.6 V.W. ρ
• 3.6 W.Dr.ρ
• 3.6 V.W.Dr/ρ
