| The roller shaft 20MG23.11.09J.18 of the coal mill is the core component of the coal mill, and it undertakes the important task of transmitting grinding force and supporting the grinding roller. It transmits the hydraulic loading force to the grinding roller through the hinge shaft, so that the grinding roller can effectively squeeze and grind the coal, thereby improving the grinding efficiency. The roller shaft 20MG23.11.09J.18 not only fixes the grinding roller, but also allows the grinding roller to swing freely within a certain range to adapt to the changes in the thickness of the coal seam and the angle changes caused by the wear of the grinding roller and the grinding disc. A respirator is installed at the end of the roller shaft, which connects the sealing air and the internal oil chamber to eliminate the adverse effects caused by different temperatures and pressures to ensure the normal air pressure and good environment in the oil chamber. The roller sleeve of the grinding roller can be turned over and used after one side is worn to a certain extent to make full use of the wear-resistant material. The roller shaft is provided with an oil level detection hole for monitoring the oil level and ensuring good lubrication conditions. The roller shaft of the coal mill plays an important role in transmitting force, supporting the grinding roller, high temperature operation, lubrication and sealing, wear and maintenance, etc., and is a key component to ensure the effective operation of the coal mill. |
