Raymond Mill wearing a grinding roller and grinding ring, bearings, etc, under normal circumstances, the life of the wearing parts of these at least three of the five months, more than two or three years, which to according to the hardness of the abrasive material, the daily working hours and daily maintenance maintenance to decide. Raymond mill bearings are indispensable parts of milling machine part, milling machine at work, bearing is wear parts for the largest, so be changed regularly. Secondly grinding roller mill grinding ring blade is one of the most easily damaged parts, the milling machine the normal operation of the impact is very big, should also pay more attention to. Finally is nuts and bolts loosening of the phenomenon, this also needs to be periodically check replacement, above is Raymond Mill usually should strengthen to pay attention to the parts. Quality is good, the equipment used to a certain degree, some parts may not work properly, because equipment components also have certain life, the replacement is very normal laws of nature, but usually if regular maintenance, pay attention to equipment vulnerable parts of the use, can be very good to extend the service life of the Raymond mill, but will not give you the production bring some unnecessary trouble the.
