Tugboat as an important component of the rotary kiln , rotary kiln body plays a supporting role in the normal functioning of 
the production process , due to long running operation , there will be some problems, but need to be adjusted when the 
tugboat , Henan YuFeng remind you to pay attention to the following points : (1) seeks to maintain the kiln cylinder centerline 
is a straight line , that is struggling to shore up large Rotary Dryer      away from the centerline , force uniform principles by each tug . (2) 
In order to maintain gear , not easily adjust the 3rd roller, the first two Pier roller, followed by a # pier roller, again 3 #: ( to 
be a comprehensive analysis than the outside to the inside back into effect, but to operate , the contact surface is better 
when more difficult ) 3 . outwards retired oiler, oiler positioning adjustment bolt can retire , and then release the bolt . 5 to 
10 minutes after the operation , check the adjustment bolt and oiler base gap is snapping . Loosen the bolt degree of 
attention should not be too large. 4 When adjusted to keep supporting wheel skew the same direction, does not allow 
character type, S type , etc. ; and each adjustment should not be too large, generally at 45 degrees to 90 degrees , up to 
more than 180 is appropriate, ( less than 30 degrees ) , adjusting bolt pitch 4mm. 5 adjustment , try to keep both sides of 
the supporting wheel centerline total distance constant, so as not to raise or lower the centerline of the cylinder . 6 cylinder 
because the disk is not timely to stop the kiln kiln caused temporary bending , generally do not make adjustments , if 
bending is large, resulting in occasional round while excessive force when force should be supporting wheel slightly larger 
pan out , and after the operation and gradually returned to its original position, so that the kiln straightening .
