Method of improving accuracy of ultrasonic rotary vibrating screen

The screening method of ultrasonic rotary vibrating screen is mainly used to prolong the screening time of materials on the screen surface when the materials are difficult to screen. The longer the moving time of materials on the screen surface, the higher the probability of small particles passing through the screen hole, and the better the screening effect of materials. But at this time, it is necessary to make some improvements to the ultrasonic vibrating screen. The common way is to add a gate on the frame and the outlet of the ultrasonic vibrating screen. If you want to improve the screening accuracy, you can close the gate and let the material stay on the screen surface for a longer time, which can effectively improve the screening accuracy. To improve the screening accuracy, two vibrating screens can be used to screen the materials. At this time, one ultrasonic vibrating screen is used for primary screening and the other is used for fine screening, which can effectively improve the screening accuracy. However, the screening accuracy can be guaranteed by this method, but the equipment investment is large and the processing capacity is relatively small. Generally, when the screening accuracy can meet the needs of users, the method of adding one rotary vibrating screen and one ultrasonic vibrating screen can be considered for screening. In the operation of the equipment, if you want to achieve higher screening accuracy, you can adjust the vibration frequency to improve the screening accuracy. The higher the vibration frequency of the ultrasonic vibrating screen, the faster the movement speed of the material on the screen surface, and the higher the jumping height of the material on the screen surface, which is more conducive to the screening of small particles. The higher the output power of the ultrasonic system, the higher the frequency of the mechanical wave generated, the greater the probability of the material passing through the screen surface and the screen hole, and the better the screening accuracy. However, the higher the power, the better. Because the higher the power of the ultrasonic vibration screen, the faster the screen damage, and the shorter the service life, the lower the output power of the ultrasonic system, the better, on the premise of meeting the user's screening accuracy.
We all know that if the vibrating screen wants to achieve better screening effect, it usually needs to be evenly fed. The main reason is that the feeding volume is too large and the material layer is too thick, so the material on the screen surface of the vibrating screen is easy to accumulate, which is not conducive to the material passing through the screen. Similarly, for ultrasonic vibrating screen, it is also good to use uniform feeding mode, so as to ensure that the material is fully screened on the screen surface, which is conducive to improving the screening accuracy. A good way is to use vibrating feeder and other equipment to evenly feed, to ensure the continuity and uniformity of the material flow. For the materials that are difficult to screen, it is usually due to the large moisture content in the materials or the certain viscosity in the materials, which affect the screening accuracy and screening effect of the vibrating screen. If you want to achieve better screening effect, it is good to take certain measures to dry the material before feeding, so that the material will not be blocked in the screening process. Here we need to explain that ultrasonic vibrating screen cannot be used for screening materials with high water content.
