For industries such as mining development and daily chemical products, Raymond Mill is one of the most important production equipment. However, in daily production, even the Raymond mill with the best quality will have various failures due to some man-made improper operation or wear of the equipment. When the Raymond grinding machine malfunctions, what is the cause and what kind of treatment is needed? Let's get to know each other together.
Under normal circumstances, Raymond mills are more prone to failures including abnormal sounds in the stone coal, sudden increase in current, and abnormal vibration inside the main engine. What is the cause? Here, we can tell you very positively that the abnormal sound of the stone coal part of the Raymond mill is caused by the serious wear of the stone coal scraper and the small gap between the stone coal scraper and the low shell, and the current suddenly increases or There is abnormal vibration sound in the main machine, which is caused by the sliding cover of the Raymond mill grinding machine, or the installation of the grinding hydraulic load rod limit block. At this time, it is necessary to stop the grinding inspection.
In addition, during the operation of the Raymond mill, the leakage of the pulverized coal tube at the outlet of the Raymond mill and the opening of the pneumatic plug-in door of the stone are also occasional. This is due to the Raymond type. The pulverized coal pipe of the mill is seriously worn, caused by stone coal, stuck coal in the inserting plate, aging deformation of the sealing packing and problems with the solenoid valve of the pneumatic system.
In the event of these failures, in addition to the Raymond mill machinery shutdown, the production company also needs to do some emergency treatment of the Raymond mill machinery, such as checking the Raymond mill mechanical scraper, the wear is serious and timely. Replace and adjust the gap between the scraper and the low shell by 5-10mm, remove the gland bolts, replace the cut bolts, reinstall the grinder gland of the Raymond grinding machine, and require all bolts to be evenly loaded, tightened in place and clicked. The welding is firm, the loading rod limit block is refilled, etc., so that the failure of the Raymond grinding machine can be solved in time, and the possibility of further damage of the Raymond grinding machine due to the failure is reduced.
In fact, no matter what kind of industry the Raymond mill is used for, the equipment failure and wear and tear are certain to happen. This is not to say that the quality of the Raymond mill is problematic, but with the equipment. When used, Raymond grinding machine will wear out, so when the Raymond mill is faulty, it must be handled in time to avoid further losses.
