What are the reasons that cause the Raymond mill roller to not move

Raymond mill is a kind of mechanical equipment used for a variety of ore grinding powder processing, and Raymond mill is mainly used at work roller grinding powder materials for processing, so roller is a very important in the production of Raymond mill accessories, Raymond mill as machinery and equipment at work hard to avoid can appear some fault, such as the following to introduce the roller, the phenomenon of the turn to be not moved, this is what causes? And I'm going to go through it for you.

 

Raymond mill roller is mainly by the mill at work within the driven shaft, if the work roller in turn, the first thing to check whether the internal axle suspension bearing is abnormal, if the gap is too big, mill vents makes this time along with the material of dust into the dust of the outside world in the mill, if fell on the bearing and lubricating oil are mixed together, thus forming a lot of dirt, so lubricating oil does not work, lose lubrication, resulting in increase of bearing friction, hindered the flexible operation of grinding roller, resulting in the phenomenon can not rotate. The grinding roller should be removed, oil and dust cleaned, and lubricants refilled so that production can be carried out.
