Used crusher in the course of the problems often occur

Mechanical faults like a broken string zither, will directly affect the production efficiency; the secondary crusher because of its high efficiency, high precision grinding and become a kind of mining equipment of various processing production line equipment can not be less; but it is also often lead to some of the technical aspects of the fault due to this treatment it is widely, so today the Oriental second-hand equipment will bring you some analysis of the faults in use secondary crusher often appear and main solutions;
1, elastic coupling produces percussion sound
Analysis of the reasons: 1 elastic ring wear off the 2 pin shaft
The methods are as follows: 1 replace the elastic ring to stop 2 and tighten the nut
2, out of grain
Cause analysis: 1 hammer wear too large 2 sieve faults
The processing methods are: 1 replacement hammer 2 replacement screen
3, the machine internal percussion
Analysis of the reasons: 1 non broken material into the inside of the machine 2 liner fasteners loose, hammer impact on the lining board 3 hammer or other parts of fracture
The treatment methods are as follows: 1 stop, clean up the broken chamber, check the tightness of the lining board and the gap between the hammer and the screen bar; 3 replace the broken parts of the 2
4, the secondary crusher vibration.
Analysis of the reasons: 1 anchor bolts loose 2 triangular disc or disc 3 hammer broken crack, rotor imbalance of 4 pin shaft bending, breaking 5 or by replacing the hammer head cone rotor static balance not abrasion.
Solution: 1 fastening bolt 2 welding repair or replacement of 3 replacement hammer 4 replacement pin 5 to unload the hammer, according to the weight selection of hammer, so that each branch of the total weight of hammer shaft hammer and hammer shaft relative to the total weight of the hammer is equal, which meet the requirements of static balance.
