Kiln support roller refers to support roller for rotary kiln, bear part of weight of rotary kiln, helps kiln body and large ring rotate stably. The supporting wheel with strong endurance has become one of the standards to measure the good quality of rotary kiln products.

Kiln support rollergirth gear, and kiln thrust roller are three necessary auxiliary equipment of rotary kiln.

Kiln Support Roller Alignment

In order to ensure the long-term reliable operation of the rotary kiln, during the operation of the rotary kiln, the primary task in terms of mechanical maintenance is to maintain the “straightness and roundness” of the kiln body and the stability of axial movement, and it is important to complete the above tasks. One of the tasks is to adjust the rollers correctly.

The basic principle of adjusting the roller

Adjust the supporting roller so that the center line of the kiln body is a straight line. The kiln body of the rotary kiln is supported on the multi-block supporting roller through the tire belt. Under the condition that the size of the supporting parts remains unchanged, the position of the kiln body is determined by the position of the supporting roller. . During the use of the rotary kiln, the position of the supporting roller should be adjusted frequently to ensure that the center line of the kiln body is in a straight line.
Adjust the supporting roller to make the kiln body swim normally. During the operation of the rotary kiln, in order to make the surface of the supporting roller and the belt wear evenly, the kiln body should continuously move axially between the upper and lower stop wheels (called swimming).
