How To Effectively Prevent Blockage Of The Ultrasonic Vibrating Screen Mesh?

The blockage of the ultrasonic vibrating screen mesh is a common problem, and the following are some effective measures to prevent blockage:

1. Choose the appropriate sieve: Based on the characteristics of the material and screening requirements, choose the appropriate sieve material, aperture, and wire diameter. For example, for materials that are prone to clogging, a screen with larger mesh and finer wire diameter can be selected to increase the effective opening rate of the screen and reduce clogging.

2. Regularly clean the sieve: During the screening process, regularly clean the residual materials on the sieve to keep it clean. This can be achieved through manual cleaning or the use of automatic cleaning devices. The automatic cleaning device can effectively remove clogged materials on the screen through ultrasonic or mechanical vibration methods.

3. Adjusting screening parameters: Adjust the vibration frequency, amplitude, and other parameters of the ultrasonic vibrating screen based on the material characteristics and screening effect. Appropriate vibration parameters can increase the jumping and rolling of materials on the screen, which is beneficial for material screening and reducing blockage.

4. Improved material handling: For easily clogged materials, pre-treatment can be carried out before entering the screening machine, such as crushing, drying, and impurity removal. Through pretreatment, factors such as large particles, fibrous materials, and moisture that are prone to clogging in the material can be reduced, thereby reducing the risk of screen clogging.

5. Regular inspection and maintenance: Regularly inspect the wear and damage of the screen mesh, vibrator and other components of the ultrasonic vibrating screen, and replace and repair them in a timely manner. At the same time, lubrication and maintenance should be carried out on the equipment to ensure its normal operation and reduce screen blockage caused by equipment failures.

6. Adopting advanced screening technology: Adopting advanced screening technologies such as high-frequency vibrating screens, rotating screens, etc., these technologies have higher screening efficiency and better anti clogging performance.
