1. Regularly stop the observation door and observe the internal wear of the impact sand making machine. The wear degree of the center feeding pipe, cone cap, impeller upper and lower runner liner, circumferential guard plate and wear block should be replaced in time after wear or Repair, replace the wear block at the same time, to ensure that the wear block weight is the same. It is forbidden to open the observation door during the working process of the crusher to observe the internal working conditions to avoid danger. It was found that the impeller body wear was replaced in time to find a manufacturer to repair. In particular, it is strictly forbidden to make the impeller yourself without the manufacturer's consent.
2. The sand making machine should add the appropriate amount of grease when working for 400 hours. When the work reaches 2000 hours, the spindle assembly should be opened to clean the bearing. If it is working until 7200 hours, it must be replaced with new ones. The bearing is gone.
3. The tension of the transmission triangle tape should be adjusted appropriately to ensure that the triangular tape should be grouped and matched, so that the length of each group is as uniform as possible. Should be adjusted, the difference between the two motor currents does not exceed 15A.
4. In the course of work, because the sand making machine belongs to high-speed running equipment, special attention should be paid to safety. The staff should be away from the equipment. If it is necessary to repair the machine, it must be powered off before operation.
