The mill is produced in order to meet the requirements of the continuous refinement of vertical roller mill, equipment already has the advantages of high efficiency, energy saving and environmental protection, simple operation and other advantages, making its application more simple, more people are welcome, the scope of its application have already penetrated the numerous chemical industry, people's attention already from performance. First, equipment parts are complete and intact, and then check the machine when it is running is stable, vibration will not occur, but also pay attention to, feeder is flexible, ensure uniform material, this is the first condition for normal production machine Second, establish various accessories for mill materials processing depends on the internal device and operating system, so before starting, check whether the wear of equipment spare parts, the operating system is sensitive and reliable, it is a necessary condition to achieve efficient production Third, the production system of vertical milling machine, more and more complete, automated intelligent requirements, in the production of automatic protection device, so to check prior to the start of spring buffer and safety protection device and all kinds of instruments are complete, ensure the production of automatic protection device can be started
