Impact crusher is a new type of high efficiency crusher developed on the basis of foreign advanced models. It has the advantages of unique structure, convenient operation, high efficiency and energy saving, cube shaped product, adjustable size and selective crushing. Impact crusher in the use of the process often appear abnormal vibration, bearing heating and other conditions, I do not know how to deal with, the following we will be specific analysis.
Abnormal vibration of impact crusher
1. It indicates that the material is too large. You can check the feed size.
2. Uneven wear indicates that the impact hammer needs to be replaced.
3. The rotor is unbalanced and needs to be adjusted.
4. If the foundation is not properly treated, the foundation bolts shall be checked and reinforced.
Bearing heating of impact crusher
1. It indicates that the bearing is short of oil and needs to be refuelled in time. Of course, if the oil is too much, the bearing will be heated. The oil level must be checked when adding oil.
2. If the bearing is damaged, the bearing should be replaced in time.
3. If the upper cover is too tight, the bolts should be adjusted properly and the tightness should be appropriate.
The discharge particle of impact crusher is too large
1. It indicates that the hammer head is worn and needs to be adjusted or replaced,
2. The clearance between hammer head and impact plate is too large, which is generally adjusted to 15-20 mm.
3. Too large feed particles will also affect the discharge particle size.
Crusher belt overturning
1. The belt is worn and needs to be replaced.
2. Because of the problem of belt conveyor assembly, the pulley should be adjusted on the same plane.
3. Pay attention to the quality of the V-belt itself.
The above several situations basically summarize the common faults of crusher. As long as reasonable response is made in the process of use, the impact crusher will be greatly improved in terms of service life and production capacity.
