Abnormal Vibration of Impact Crusher

The impact crusher can handle heavy materials with side lengths of less than 100-300 mm. Its compressive strength can reach 350 MPa. It has the advantages of large crushing ratio and cubic particles of mine materials after crushing. The equipment has small volume, simple structure, large crushing ratio, less energy consumption, large production capacity, uniform product size, and selective crushing effect. It is a promising equipment. It is widely used in ore crushing, railway, highway, transportation, cement, mining and other industries for medium and fine crushing materials. In the working process of the impact crusher, special attention should be paid to the following situations.

If abnormal vibration of impact crusher is found

  • 1. Explain that the material is too large, you can check the size of the feed.
  • 2. The uneven wear indicates that the counterattack hammer needs to be replaced.
  • 3. The unbalanced rotor needs to be adjusted.
  • 4. Improper foundation treatment requires inspection of anchor bolts and reinforcement.

If it is found that the bearing of the impact crusher is heated

  • 1. Explain that bearings are short of oil and need timely refueling. Of course, too much refueling will also make bearings hot. When refueling, we must check the oil level.
  • 2. If the bearing is damaged, the bearing should be replaced in time.
  • 3. The upper cover is too tight. The bolts should be adjusted properly and tightened appropriately.

If it is found that the discharging granularity of impact crusher is too large

  • 1. Explain that the hammer head is worn and needs to be debugged or replaced.
  • 2. The gap between hammer head and counterattack plate is too large, which is generally adjusted to 15-20 mm.
  • 3. Excessive feed size also affects the discharge size.

If the belt of the impact crusher turns over

  • 1. Explain that the belt is worn out and the triangle belt needs to be replaced.
  • 2. Because of the problem of belt conveying and assembling, the pulley should be adjusted on the same plane.
  • 3. We must pay attention to the quality of the triangle belt itself.
