There should be no serious burns, blackening, wear, or minor burns. Parts need to be treated properly before leaving the factory
5.9 Load test run is carried out by the user and meets the following requirements: a) No-load operation should comply with the provisions of 4.4: b) Half-load operation for 4 hours;
c) Full load operation should comply with the provisions of 4.5: d) There is no abnormal change in current:
Feeding and discharging are normal.

5.2 When checking the gear meshing time, the eccentric sleeve should be close to the frame bushing on the side of the pinion and measured using the lead pressing method. 5.3 When checking the axial clearance of the transmission shaft, the back of the pinion should be close to the end face of the sleeve of the transmission shaft. , use a feeler gauge to check the gap between the end face of the drive shaft bushing on the other side and the oil slinger.
5.4 Check the size of the ore discharge port by using a lead ball fixed on the steel wire and measure it at four points roughly evenly distributed around the crushing cavity. The arithmetic mean of the dimensions after extrusion of the four-point lead balls is the size of the ore discharge port. The diameter of the lead ball used for measurement should be larger than the size of the predetermined discharge port. The processing capacity of the 5.5 crusher can be calculated using a belt scale or by weighing the materials on the unit length feeding conveyor belt, and then calculating it based on the speed of the conveyor belt.
