The rod mill is a kind of grinding equipment designed with the grinding body in the barrel as the main force. It is a kind of equipment that can meet the high granularity requirements of the finished product. The rod mill can be dry-grinded or wet-grinded according to the working form. It is widely used in chemical, metallurgy, glass, refractory and other industries.
The working principle of rod mill is that the barrel rotates at a certain speed, and the grinding body rises to a certain height under the action of friction and centrifugal force, and is thrown away, so that the material is impacted and ground to achieve the purpose of grinding. The rod mill has abnormal vibration and impact noise during work. The reasons and solutions are as follows:
The rod mill's gears are not well coupled or worn seriously, the anchor screws or bearing screws are loose, the large gear connection screws are loose or the split bolts are loose, and the transmission bearing wear is serious, which will cause the rod mill to vibrate abnormally. The above problems should be solved by adjusting gear clearance, tightening loose bolts, and replacing transmission bearings.
Most of the impact sounds during the operation of the rod mill are due to gear problems, such as foreign objects mixed between the large and small gears, loose pinions, broken gears, or loose screws on the bearings, which will cause this problem, so check the gears in time. Foreign matter, replacement gear and screw tightening measures to resolve.
