The riding ring, also known as tyre, is one of the core supporting parts of rotary cement mills and rotary kilns.

Mounted tightly on the mill shell, it transfers the total weight of the mill cylinder, grinding media and materials to the supporting rollers. During operation, it rolls steadily on the supporting rollers to maintain the normal rotary movement of the whole equipment.

We adopt premium cast steel material and strict heat treatment process. The product has uniform hardness, strong bearing capacity, good fatigue resistance and outstanding wear performance. Precise machining guarantees high roundness and smooth surface, effectively reducing vibration and abrasion during operation, and extending the service life of matching parts.

It is widely applied in large, medium and small cement grinding systems and rotary kiln production lines.
