No-load test should meet the following requirements:

1) The lubricating point lubrication is normal, there is no oil spill phenomenon.

2) The temperature of the vertical grinding main bearing should not exceed 50 ℃.

3) The slag vertical ultrafine grinding runs smoothly, the gear transmission has no abnormal noise.

4) The liner and the transmission parts without loosening.

5) ministries running in line with maintenance requirements.

When the idling reaches the specified time, stop the vertical grinding operation of the slag, carefully inspect all the working parts, tighten the liner bolts to eliminate the defects found.After passing the no-load test, load test can be carried out. Load test to gradually feed until full load. After normal feeding run 10 ~ 20 h.
