Tangential tyre suspension
The ROTAX-2 suspends the kiln concentrically inside tangentially suspended tyres. This design allows the kiln shell to expand freely, completely eliminating the risk of shell constriction and the need for tyre migration monitoring systems. It ensures reliable transmission of drive power under any operating conditions, eliminating the need for lubrication as well as wear between tyre and kiln.
Double-lamella seals
The double-lamella seals at the inlet and outlet of the kiln reduce false air intake yet allow enough flexibility to follow the kiln’s movements.
The seals require no greasing and are practically maintenance-free.
Additional design details
Self-adjusting roller suspension maintains constant contact with all four supporting rollers; ensures efficient transmission of torque and minimises stresses that cause pitting and cracks
Kiln alignment not affected by settling of the foundation – makes periodical realignment unnecessary
No kiln girth gear and few supporting rollers – means low maintenance costs
Relatively slow speed at the kiln inlet lessens dust circulation, reducing kilocalorie consumption and facilitating operation
