The maintenance of the ultrafine mill is a daily work that the user must do, so that it will not cause the machine to be in use, causing major problems. In addition, the maintenance work must be adhered to, after each shutdown, to check whether the bolts of the various parts of the machinery loose, if it is loose, it must be sturdy, check the amount of lubricant in the bearing room before and after the host, and make recharge on time, the bearing chamber with the injection axis Lithium-based lubricating oil is injected into the cap lubricator. Of course, when it comes to lubrication, it must be prepared, which is related to the quality of lubrication. Therefore, we must first check the bearing lubrication conditions of the bearing housing before and after the host, such as grease scale, must be cleaned; to update the grease, look at the bearing wear condition to see if it needs to be replaced. In addition, check the bolts on the outside of the ultra-fine mill and ask for its robustness. To open the host, check the hammer hammer wear condition, if you need to update the new parts; check the fan blade connecting bolts, whether loose, if the leaves are seriously worn out, if it should be loose or replace the loose; check the smashing parts of the various parts of the liner and Whether there is looseness of the body fixing bolts, looseness should be firm, new parts should be replaced with serious wear of the lining plate; check the inside of the burner to remove the scale and repair the lining.
