How to Calculate Extruder Screw Torque
Usually calculated from the motor power
In the case of a single-screw extruder, the output torque T = P * 9550 / n / 1.05, where P is the motor power, 9550 is the factor, n is the maximum screw speed, 1.05 is the energy loss through the gearbox drive 5 % Of the loss
In the case of a twin-screw extruder, the output torque is T = P * 9550 / n / 2 / 1.05, with the exception of 2 because the output torque is given to two screws and the single screw torque is calculated.
The value calculated by this formula is usually slightly higher than the actual value because, for example, the design of single-axis torque is 200N.m, the required motor power is in accordance with the design of single-axis torque using the above formula out of. Because the standard motor power is leapfrog, the calculated motor power is not exactly there, so the one closest to the motor is selected to ensure sufficient output torque.
