What caused the grinding mill to vibrate violently?

Posted: 2020-04-21

• Good grinding mill runs steadily and reliably, with low vibration and low noise. If the mill used by the customer suddenly vibrates suddenly, it should be an abnormal condition encountered by the equipment, which may cause damage to the equipment. We should pay attention to the maintenance of the ore mill.

  Based on its many years of experience in the field of mine mill, Shanghai Clirik Machinery Co., Ltd summarizes the following reasons for the severe vibration of the mill:

  
  1. The material is too hard

  
  The ultra-fine powder mill has a strict limit on the hardness of the material. If it exceeds its working range, it will cause a drop in output, a severe vibration of the host, and an excessively thick stone powder. Therefore, the hardness of the material must be well controlled.

  
  2. The material is too fine

  
  The material is as fine as powder, and there is no friction between the grinding roller and the grinding ring. The vibration of the host can be controlled by adjusting the speed of the host.

  
  3. Uneven feeding

  
  If the mill suddenly appears too much or too little feed, it will cause severe vibration of the mill. The feeding amount can be controlled by adjusting the vibrating feeder.

  
  4. Loose anchor bolts

  
  This phenomenon is more common, mainly because the vibration during the grinding process of the machine will lead to the loosening of the bolt, which in turn will cause the vibration to increase. Check the machine in time and tighten the bolts.

  
  5. Deformation of grinding roller

  
  Long-term wear causes the shape of the grinding roller to change, and the grinding roller is not smooth, resulting in violent vibration during rolling. The grinding roller should be replaced in time.

  
  6. Installation failure

  
  During the installation process, the center line of the transmission part of the host is not straight, and vibration will occur during the rotation. Adjust the centerline in time.
  
  The user should solve the problem of excessive vibration of the grinding mill in time. The operator should also continue to learn and master the principle of mechanical operation, reduce the probability of failure, and allow the equipment to be safely and efficiently put into production. Questions about all aspects of the equipment are welcome online Inquiries.
