Technical Field

[0001] This utility model relates to the field of sealing structure technology, and in particular to the sealing structure of Raymond mill roller bearing. Background Technology

[0002] Raymond mill is a widely used grinding equipment, widely used in mines, cement plants, and chemical plants for grinding. It is one of the important equipment for the deep processing of non-metallic minerals, and has the advantages of stable performance, strong adaptability, and high cost performance.

[0003] The grinding roller revolves within the grinding ring, generating centrifugal force to pulverize the material, while also rotating under friction. The bearings supporting the grinding roller shaft are divided into upper and lower parts. The upper bearing is farther from the pulverizing zone and is less prone to damage, while the lower bearing, being closer to the pulverizing zone, is exposed to dusty conditions and is more susceptible to vibration. Dust easily enters the bearing, causing damage. Therefore, frequent shutdowns for maintenance are necessary, resulting in a large workload, impacting production, and reducing overall production efficiency. Utility Model Content
