kiln support roller
Weight7~42 t
MaterialASTM: 1055 / DIN: 42CrMo4
ApplicationRotary Kiln
Support roller (support wheel)bears the whole weight of rotary kiln (including barrel, inside bricks, heat exchange device inside kiln, raw material, rolling ring, gear ring), which makes the barrel and the rolling ring rotates smoothly on kiln support roller Therefore supporting roller with strong endurance has become one important standard to judge quality of rotary kiln

Support Roller Design:

The basic design of support rollers has changed little over the years. The support rollers are mounted on a massive cast iron or steel base plate which provides the inward horizontal forces on the rollers and distributes the weight of the kiln over the pier. The spacing between the rollers has to be small enough to prevent large horizontal forces, but large enough to keep the kiln laterally stable. Rollers are designed to subtend 60° at the tyre centre, and this seems always to have been the case. Minor adjustment is allowed so that the kiln can be kept aligned (i.e. to keep the centres of the tyres co-linear) as small changes take place, such as wear of the tyre or settlement of the pier. The roller outer face is made wider than that of the tyre, mainly to allow for contraction of the kiln during shut-down.


Supporting wheels from Great Wall Steel Casting were installed on rotary kilns of many customers with reliable performance.

Great Wall Steel Casting can produce all types of supporting wheels according to customers’ drawings and sizes. You are warmly welcomed to visit our company!
