Now on the market mainstream a milling equipment is ultrafine mill, has better performance in production, the majority of customers are welcome and recognition, has also brought good prospects for manufacturers, is a very good development prospects in the mill, but it is for processing materials, will be some wear, the service life of ultrafine grinding mill is limited, we in order to prolong the service life, increase production engineering benefits, the general will think of a way to prolong the service life, so are the means by which to achieve this demand? 1. the mill ring grinding roll is an important component, and is the key part of normal powder production. General to replace the roller when in use for more than 600 hours, the link roller sleeve, rolling bearings should be cleaned to remove oil dirt, timely replacement of worn parts, available manual pumps for refueling, the purpose of which is to the grinding roller and grinding ring could be done better the production of materials, and reduce wear production, prolong its service life; 2. ultrafine grinding equipment after a period of time, must be checked and maintained, this point is the maintenance of the various internal components, it is in order to reduce wear, and regular lubrication is also very important, in order to better achieve this operation, we can at the time of production, the development of safety operation rules, regular maintenance and maintenance, prolong the life of parts so as to better achieve the purpose;
