As the kiln rotates, there is circumferential displacement between the tire and the shell as a result. This motion is commonly

ANALYSIS AND REDESIGN OF SPOKES ON ROTARY KILN

rotary kilns are usually very sturdy in design and operate at low speeds. The peripheral speed in mills is normally 6 to 10 ms–1 and in kilns 0.3 to 3.0 ms–1. The main drive characteristics are: high output torque large, sometimes variable centre distance medium to high modules tooth width up to approx. 1,200 mm, depending on the drive
