Problems that may occur in the vibrating screen at work

Vibrating screen is one of the commonly used screening equipment. It has the advantages of high screening efficiency, high screening quality and large processing capacity, and is favored by customers. Then the following analysis and solutions are given for the problems that may occur in the screening process of the vibrating screen.

1. When the vibrating screen is screened, the material on the screen surface is discontinuous, and the vibrating screen has vibration problems when the vibrating screen is started or stopped. The solution to such problems is to adjust the position of the eccentric wheel and increase the mass of the eccentric wheel. Another: The occurrence of such problems will reduce the service life of the spring and should be resolved in time.

2. The vibrating screen bearing seat is easy to vibrate, the bearing is easy to heat and damage, and the bottom beam of the screen is easy to weld or break. The problem is that the mass of the eccentric wheel of the sieve machine is too large, which results in the increase of the exciting force and the increase of the sieve amplitude. The common solution is to reduce the mass of the eccentric or change a spring with a larger stiffness to deal with it. Under the premise of ensuring the strength of the shaft, it can be dealt with by changing different types of bearings or changing the strength of the bearing seat. At the same time, the necessary reinforcement of the bottom beam of the screen machine can also extend the service life of the screen.

3. The amplitude of the vibrating screen is lower than the required parameters. The detailed performance is that the amplitude is too low. If the amplitude is low, it will reduce the overall treatment effect of the vibrating screen; on the contrary, if the amplitude of the vibrating screen is too high If the condition is high, it will have a certain impact on the service life of the bearing housing, bearing, and bottom beam of the vibrating screen. Therefore, under normal conditions, the user can directly modify the quality of the eccentric wheel according to the application site conditions of the vibrating screen, or select springs of different stiffness to adjust the amplitude of the vibrating screen to a certain extent, so as to achieve production. demand.
