The force distribution should be greater than 70%. When running empty, if the lubricating oil system works normally and no oil leakage occurs, the dolomite powder machine runs smoothly without obvious noise, the vibration value of the main bearing, motor and pinion does not exceed 0.1mm, and there is no obvious damage or hot phenomenon of each part. The empty car runs normally.

During the test run of the dolomite powder machine under load, according to the proportion of the dolomite powder machine, a certain amount of steel balls are added to the barrel of the dolomite powder machine, and the steel balls are added in batches. During the operation process, the bearing temperature, current, and vibration intensity are measured.

After the dolomite powder machine is installed, start running with load, add 70% of the specified load to the grinding material, and continue to run for more than 10 hours. During the process, the threaded joints of the dolomite powder machine lining should be tightened and the threaded connections should be checked frequently to prevent loosening.
