Analysis of several faults in Raymond mill
« on: March 14, 2019, 06:38:51 AM »

Raymond mill is a kind of milling machine imported from abroad. After the raw material of the ore is simply broken and crushed by the jaw crusher, it is transported to the storage bin by the bucket elevator, and then the material is transferred to the main grinding chamber of the Raymond mill through the electromagnetic vibration motor of the discharge port of the silo. The semi-finished fine powder is ground between the grinding roller and the grinding ring, and the fine powder is brought to the analysis machine by the fan airflow, and analyzed and screened by the analysis machine to meet the process requirements, and the air is brought to the large cyclone collector by the airflow. Auxiliary equipment for Raymond mill equipment. Here are a few common faults.
The parts are loose, and the parts that are newly processed and assembled have geometrical deviations. Because of the alternating load such as impact and vibration, as well as the influence of heat and deformation, and the wear and the like, the original fastening is easily made. The parts are loose. The deformation of the cylinder, the main reason for the deformation of the Raymond mill is that the mill causes the deformation of the cylinder under the combined action of the weight of the cylinder, the weight of the abrasive body and the weight of the material. When the machine is stopped for a long time, the tight body and part of the material are technically unloaded; the lubrication is poor, because the matching clearance of the newly assembled parts is small, it is difficult to ensure the average of the matching gap, and the lubricating oil is not easy to form an average on the friction surface. The oil film prevents the Raymond mill from wearing, which reduces the lubrication efficiency and causes abnormal wear in the early stage of the machine.
