The Roll Crusher Capacity Calculator helps engineers and operators determine the theoretical capacity of a roll crusher based on various parameters. Formula: To calculate the capacity of a roll crusher, you can use the following formula: Capacity = (2.5 * R * L * S) / (V * T * H) Where: R is the roll diameter. L is the length of the roll.

The power required was 0.8 I.H.P. per ton crushed in 24 hours. The capacity was 62½ tons per day for each set of 8 rolls, and the total cost, exclusive of lighting, breaking, and drying, was 3s. 10d. per ton. The crushed ore was roasted and chlorinated. The rolls have now been superseded by Krupp ball mills.

So 3500 PSI = F/A. I solve for Force so Force = 3500 * .5 = 1750 That equals 1750 Lbs of force. Now solve for how much torque i need from my motor. Torque = Force * Distance so Torque = 1750 * 1.75″ = 3063 inch-pounds of torque. lets say i have a motor that rotates at 5 rpm.

The load profile is an approximation of the aggregate energy required from a power system over a particular time period (e.g., years, days, hours). The load profile is demonstrated in a two-dimension graph exhibiting the instantaneous load (in Volt-Amperes) over a certain period of time and presents an easy way to visualize loads changes with time.
