Tire Migration/Creep/Relative movement. – Rotary kiln

After one revolution of the kiln we can observe line separation. By measuring this line separation we can read the value of creep. This parameter can be easily recalculated into undertire clearance (gap). Creep divided by 3,14 (Pi) gives us the gap. For most kiln producers tolerance for undertire clearance is between 3 to 6 mm in hot condition.
