The following is the matters of the purchase of the vibrating screen that the manufacturers introduce to the users. When selecting the vibrating screen, the users should use the larger mesh size, larger effective screening area and non-metallic sieve surface and the appropriate choice of the sieve shape as much as possible in order to improve the capacity and efficiency of material particles passing through the sieve.
The role of the vibrating screen stretching circle:
To protect the fine mesh to avoid the sieve grid crushing the sieve; the sieve cell edge sealing is strengthened to prevent leakage of material. If it is the thick filament diameter screen, the stretching circle will affect the operation, which will increase mesh difficulty, it may be required that there should be no stretching circle.
The pros and cons of closing trays and the application range:
The advantages: it can avoid direct discharge of the edge of the material; the material is collected to the middle of the screen to improve screening accuracy. The drawbacks: it will increase the weight of the upper part of the screen machine, reducing the vibration transmitted force, weakening the effect of screening. If the closing trays have crack, it will increase the sales costs. The scope of adaptation: it can be applied to the vibration sieve with smaller diameter for the demand for special screening. Currently, because that the height is limited, the closing trays will make it easy to cause the blockage for the material. The general screening should not add the closing trays.
The pros and cons of the ball plate of the vibrating screen:
The bouncing ball helps to clean up the sieve and enhance the screening effect. The drawbacks: it will increase the weight of the upper part of the screen machine, reducing the vibration transmitted force and weakening the effect of screening.
