1. Test machine of hammer mill
After the hammer mill is installed, it needs to run without load. The following work should be done before test machine:
(1) Check whether there are tools and sundries on the machine.
(2) Appropriate lubricating oil should be added to each lubrication part.
(3) All fastening parts should be tightened.
(4) Adjust the roller pitch of the feed roller to 0.5mm, and the roller pitch at both ends of the roller is required to be basically the same.
(5) Check whether the wiring is correct according to the electrical schematic diagram.
(6) Check whether the tightness of the triangle tape is appropriate.
(7) Check whether the water inlet and spray pipes are unblocked, and there is no leakage, and whether the direction of ice spraying of the spray pipes is correct. · After the above-mentioned work meets the requirements, it can be turned on for no-load operation.
2. The following items must be checked during no-load operation:
(1) Whether the rotation direction of the rotor and the feed roller is correct.
(2) Whether the electrical control part is sensitive and whether the starting time of the motor is adjusted properly (for the starter equipped with a time relay).
(3) Whether there is any abnormal impact sound during operation.
(4) Whether there is oil leakage in each sealing part. Whether each threaded connection is loose.
(5) After 2 hours of no-load operation, the temperature rise of each bearing does not exceed 650℃ (when the ambient temperature is 15-30℃).
