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 eliminate 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.
