The Raymond mill mostly operates in wet environment, but it is not protected from dust.When some fine dust enters The Bearing Seat Of Raymond Mill running at high speed, the lubricating oil in the bearing seat will deteriorate and the quality will deteriorate, resulting in the wear of Raymond mill bearing.When the Raymond mill bearing runs in the worn state, it will increase the friction and heat, resulting in an increase in the temperature of the Raymond mill bearing.Solution: the Raymond mill bearing is worn due to lubricating oil, so it is necessary to clean the Raymond mill bearing housing and bearing during maintenance, and check and dredge the refueling pipeline; Ensure that different types of grease are not mixed; If the lubricating oil of other models is replaced, the original lubricating oil shall be cleaned and replaced.Note: moisture proof and dust-proof measures shall be taken for grease storage, and lubricants of the same brand and model shall be selected as far as possible.
