As experience shows, when one determines the energy-power parameters of crushing and grinding processes by using the existing methods, the power of motors used in drives of existing crushers of various types often turns out to be excessive [10, 11].In this case, the drive will operate at a relatively low load (ratio of the power consumed by the …
The capture of a crushed piece occurs due to the stop located on the roll (see Fig. 1 ); in this case, the condition for formation of a complex stress state in the crushed piece is observed, and the energy consumption is reduced by 39–40% [ 9 ]. Fig. 1. Schematics of the crusher with stops on a roll. Full size image.

I am trying to find the required power for the motor which will provide drive to the conveyor. The conveyor's end shafts will move at 20 rpm. Also, the torque required is given through the formula:
We will skip "Required Stopping Accuracy" and "Other Requirement (s)" for this example. Motor Requirements: Load Inertia = 58,752 oz-in². Required Speed = 19.1~38.2 RPM. Required Torque = 209.4 lb-in. The easiest way to find a suitable motor is to use the "Search by Specification" tool for the specific type of motor.
Belt Pull = Total Weight x frictional coefficient. Belt Pull = 280 lbs x 0.5. Belt Pull = 140 lbs. Then, convert this to required power. Required Power = Belt Pull x Belt Speed. Required Power = 140 lbs x 50 fpm = 7,000 ft-lbs/min. Convert that to a useful unit of measure. One horsepower (HP) equals 33,000 ft-lbs/min.

It is easy to calculate angular speed if you know rotational speed of the motor in rpm: ω = rpm * 2π / 60. where ω – angular speed, measured in radians per second (rad/s); rpm – rotational speed in revolutions per minute; π – mathematical constant pi (3.14). 60 – number of seconds in a minute.

A2: Material hardness plays a significant role in determining a roll crusher's capacity. Harder materials generally require more crushing force and can reduce the crusher's capacity. Q3: Can the Roll Crusher Capacity Calculator be used for other types of crushers? A3: This calculator is specifically designed for roll crushers.
To clarify the results of determining the crushing force in a roller crusher, it is recommended [2, 3] to use the loosening coefficient of the material, which constitutes 0.2–0.3 for strong rocks, 0.4–0.6 for clay, but it has quite a wide range of values and does not allow calculating the required value of the drive power of roller crushers ...
The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.
