The hydraulic axial thrust systems are arranged downhill relative to the tyre. It counteracts the downhill force of the inclined rotary kiln. The system is driven by a fully pre-assembled hydraulic unit located in direct vicinity of the tyre station. Adjustable proximity switches are used for limiting the range of movement. A distinguishing feature is that the design is matched to the respective rotary kiln, which means that the probability of failure is very low.
The installed hydraulic accumulators compensate for pressure afluctuations that can occur due to wobbling tyres. All the supporting rollers can be set parallel or at a slight angle to counter the downhill force. As the system ensures uniform loading of the supporting rollers and pinions, spalling and edge contact is prevented.
