Raymond mill as the specific powder manufacturing apparatus, is suitable for the fine powder processing of various minerals and coal. Raymond mill equipment with the vertical structure and small footprint, it has strong systematicness, from the rough machining of raw materials to conveying and pulverizing and to the final packaging, Raymond mill can form an independent production system, at the same time, it has high productivity. In order to keep the Raymond mill productive all the way, the daily maintenance of Raymond mill is also a very important task.

●In the grinding progress of Raymond mill, there should be the regular personnel responsible for supervision, firstly, the operator must possess the certain technical level, then the powder plant must make the necessary technical training to operators and make them fully understand the working principle and performance of Raymond mill, after they have been familiar with the operation procedures, can permit them to control the Raymond mill.

●After a period of production time, we should carry on the maintenance to Raymond mill during its downtime, at the same time, repair or replace the grinding roller, grinding ring, blade and other vulnerable parts of Raymond mill. We also should examine the bolt and nut of connecting the grinding roller device, see whether there is the loose phenomenon.

●If the use time of Raymond mill is more than 6 months, we should clean and check the host central shaft system, transmission device, grinding roller device, analytic machine and the oil tank of Raymond mill, after the cleaning and inspection, add the enough lubricating oil on them.

●If the grinding roller device of Raymond mill has been used more than 500 hours, we should replace the grinding roller, clean up every antifriction bearing in the roller shell and replace the damaged parts timely.

●The condemning limit of Raymond mill's grinding roller and grinding ring is that their minimum thickness shall not be less than 10 mm. In order to ensure the normal grinding operation of the Raymond mill and meet the powder requirement, once the thickness of grinding roller or ring is less than 10 mm, we must replace it immediately, so as not to affect the pulverizing effect.

●When we need to stop using Raymond mill, first stop the feeding operation of the feeder, don't stop the host and keep the equipment continuing the grinding work, until the residual abrasive materials completely discharged from the mill, then close the host motor and analyzer machine to stop the grinding work, later stop the draught fan motor so that the remaining powder is blown off the Raymond mill.
