The normal operation of the rotary kiln has a great relationship with the kiln support roller adjustment. During the installation of rotary kiln, firstly make the support roller axis parallel to the center line of the kiln body, at this time if put lead wires into the mesh points between tire and support rollers, the lead wires will be pressed in rectangular strip with same width. At the same time, the force acting on each support roller can be known according to the strip width, the support roller bearing larger force should move away from the center line of the kiln in parallel direction, and otherwise move to the direction near the center line of the kiln.

When the rotary kiln rotates, if the kiln body glides down due to weight, the support roller bearing larger force cen be adjusted to a certain extent according to the rotating direction of rotary kiln, so as to product a upword force to balance the sliding force. But it’s better that the adjustment angle of support roller axis line is not more than 30 points, so as to avoid the support roller out of shape quickly. If a support roller group is not enough to the balance sliding force, adjust the other support roller until the kiln body is balanced. During the adjustment of support rollers, make sure that the support rollers don’t decline in different direction. Because that will elliminate the forces between kiln tyre and support rollers, so taht rapidly increase the wear of tyre and support rollers and increase rotate kiln power cost.

In the management of the support rollers, the support roller bearing larger force should be used as a controlling support roller, when the kiln body slides down so that the kiln tyre contacts the lower thrust roller, pour diesel on the controlling support roller to increase the friction between tyre and support roller, then the kiln body upwards; if the kiln body move upwards to touch the upper thrust roller, you can pour engine oil on the controlling support roller to reduce friction between tyre and roller, then the kiln will slide down.
