First of all,during the operation of grinding mills, there should be specialized staff responsible for guarding the machines, and the operating staff must have the good technical level. Before the installation of grinding mills,it is necessary to conduct technical training for the operating staff，So that they can understand the principle performance of grinding mills and be familiar with the operation process. In order to make grinding mills work normally, Equipment Maintenance and Safe Operating System needs to be instituted to ensure the long-term safe-running of grinding mills. Moreover, it is necessary to reserve some maintenance tools and grease accessories.

Next, grinding mills should be examined and repaird after using a period, and the quick-wear parts such as grind roller,gear ring and scraper knife should be repaired and replaced. The bolts and nuts should be checked carefully before or after the use of grinding roller device. When replacing grinding roller after using for more than 500 hours or so, it is necessary to clean various rolling bearings and replace quick-wear parts. As to the fueling tool, manual refueling or grease gun is a good choice.

Finally, grinding mills should be operated in strict accordance with the instructions. If the equipment breaks down halfway, it can’t be modified at random but should be maintained by professionals and technicians.
