1. In the process of using the linear vibrating screen, it is not good to take the coal in the screen surface. When the screen is opened or stopped, the screen machine will oscillate and oscillate, thus affecting the service life of the spring. The solution to this problem is to adjust the position of the eccentric wheel appropriately if the front section of the screen does not take coal. If the middle part of the screen machine does not take coal, the quality of the eccentric wheel is too light and the amplitude is not up to the requirement. At this time, the quality of the eccentric wheel should be appropriately increased to solve the problem. If the coal is not taken in the rear of the screen, adjust the position of the eccentric gear backwards.
In addition: improper matching of the position of the flushing pipe on the screen surface of the sieve machine for grading or dewatering will also lead to the phenomenon that the screen surface does not go coal. The position of the flushing pipe can be appropriately adjusted to solve the problem of speeding up the running of the material on the screen surface. However, this method is only suitable for screening or dewatering of 0-3mm materials.
2. The linear vibrating screen bearing seat is easy to be cracked, the bearing is easy to generate heat and damage, and the bottom beam of the screening machine is easy to be welded or broken. This problem arises from the fact that the quality of the eccentric wheel of the sieve machine is too large, resulting in an increase in the exciting force and an increase in the amplitude of the sieve. This problem is generally addressed by reducing the quality of the eccentric or replacing the spring with a higher degree of rigidity. It can also be handled by replacing different types of bearings or changing the strength of the bearing housing while ensuring the strength of the shaft. At the same time, the necessary reinforcement of the bottom beam of the sieve machine can also extend the service life of the sieve.
3. The amplitude of the linear vibrating screen is lower than the parameters required by the design. This problem is affected by various factors. When the linear vibrating screen is put into production, the amplitude of the screen machine often fails to meet the design requirements. The amplitude is too low, which will reduce the processing capacity of the sieve. If the amplitude is too high, it will reduce the service life of the bearing housing, bearing and sieve bottom beam. Generally, the quality of the eccentric can be changed according to the use of the site or the spring of different steel degrees can be used to adjust the amplitude of the sieve machine to meet the production needs.
