3-support kiln

If the length to diameter ratio exceeds 15, it is best to support the rotary kiln on three roller stations.


 Variable-speed electromechanical drive systems with planetary gearbox, splined tyres, pneumatic inlet and outlet seals, air-cooled inlet trough, hydraulic axial thrust system etc. are proven components of both the 2-support kiln and the 3-support kiln.

Floating kiln tyre
As the classical alternative to the splined kiln tyre, Polysius offers the floating tyre, which is only fixed on the kiln shell in the direction of the kiln axis, so that it can turn in peripheral direction relatively to the kiln shell.
