rotary kiln torque formula

Rotary kiln Wikipedia

This must have high starting torque to start the kiln with a large eccentric load. A 6 x 60 m kiln requires around 800 kW to turn at 3 rpm. The speed of material flow through the kiln is proportional to rotation speed, and so a variable speed drive is needed to control this. When driving through rollers, hydraulic drives may be used.
