WEBAnalytical method for determining the energy-power parameters of the crushing process in a rotary hammer crusher with a grate is proposed.
For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.

Other power losses, caused by bearing friction for instance, are neglected to simplify the calculation. Eqs. (12), (10) are inserted in (9) and R W is substituted to get the equation for the maximum bearing force F Lh,max: (14) F Lh,max = (η U ¨ · P motor + P block) π n W · D W · sin δ. 3.2. Forces derived from material compressive strength
The total power W of a crusher drive is determined as the sum of power W 1 spent on dispersing the initial pieces loaded into a crusher and power to overcome the friction forces that occur during operation of a crusher between the crushed material and fixed jaw (W 2) and in the bearings, through which the rotation is transmitted from engine …
Comminution by gyratory crusher is the first stage in the size reduction operation in mineral processing. In the copper industry, these machines are widely utilized, and their reliability has become a relevant aspect.

The shaft power of a 3-phase alternating current motor can be calculated knowing the voltage applied, the current drawn, the efficiency of the motor and the power factor (compared to single phase, we correct by 3 1/2) : Pshaft = 1.73 * ηm * U * I * PF. With : P shaft = shaft power (W) η m = efficiency of the motor. PF = Power Factor.

Suppose you have a motor with a torque of 10 N-m and it operates at an angular speed of 1200 RPM. Using the formula: P = (10 N-m) * 2 * π * (1200 RPM) / 60. P ≈ 1256.64 watts. In this example, the motor power is approximately 1256.64 watts, indicating the power output of the motor under the specified torque and angular speed.
