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 ρ = density of material to be crushed, kg/m3 here, V =πND where, N = speed of the rolls in rotation per second (rps) D = diameter of rolls, m) ?
Correct answer: A
Explanation
The theoretical capacity formula includes the product of peripheral velocity (V), width (W), roll diameter (D), and material density (ρ).
