A new type sand making machine, empty load test run: (1) a comprehensive inspection of the anchor bolts and fasteners are devices all have tightened firmly should drive, motor wiring is correct. (2) all the nozzle according to the requirements of lubricating oil. (3) with the hand disc V, check whether the impact hammer and lining board, equipment operation is flexible. (4) to move the electric motor drive, vibration inspection equipment, such as the discovery of excessive vibration and abnormal noise test, should stop and check carefully to find out the reasons have been ruled out in a timely manner. (5) the check all normal, driving empty load operation of 2-4h (continuous). (6) shall not be more than 45C bearing temperature, the highest temperature shall not exceed 75C, otherwise, to deal with the bearing cleaning, adjust the gap, then the test run. Two, new sand making machine with a load test run: (1) the empty load test run, to make comprehensive inspection equipment, especially to check the rotor sector lining plate, anchor bolt is loose, there is no other abnormal phenomena, such as abnormal should analyze the reasons to exclude, if necessary, can be re empty load test. (2) load test should be in order to drive -- the first discharging belt conveyor, and then open the sand making machine, feeding system and finally opened. (3) load test 8-24h (4) load test of parking should be carried out in sequence, first stop feeding system, then stop the crusher, finally stopped discharging belt conveyor. (5) load test, to fully examine the equipment vibration, fasteners etc.. 45C bearing temperature rise to more than the maximum temperature of the bearing, to more than 75C, at the same time, the bearing surface temperature shall not exceed 80C. (6) load test, to conduct a comprehensive inspection, for everything is normal, can be formally put into production. Whether the purchase of new sand making machine which one, should according to the requirements of the above steps for debugging.
