    Rotary kiln - Wikipedia

    A rotary kiln is a pyroprocessing dev used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: 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

This parameter can be easily recalculated into under-tire clearance (gap). Creep divided by 3,14 (Pi) gives us the gap. For most kiln producers tolerance for under-tire clearance is between 3 to 6 mm in hot condition.
