What to do if the air flow screen has poor screening effect?
The screening of the airflow screen is mainly completed at the feeding end. As the inclination angle increases, there are obvious particles passing through the screen near the discharge end. This is because the larger the inclination angle, the easier it is for particles to jump to the end of the screen length and undergo secondary screening.
1、 The fine particle ratio of the airflow screen gradually increases over time. When the screen width is 10mm, the ratio of layered fine particles varies greatly. For the fine particle ratio through the sieve, the linear shape of the fine particle ratio change curve under different sieve widths is basically consistent, indicating that the change in sieve width has little impact on the fine particle ratio. When the screen width is less than 30mm, the change in the ratio of fine particles passing through the screen is relatively severe, indicating that a small screen width is beneficial for passing through the screen
2、 The screening rate of the airflow screen decreases over time. After a screening time of 1.0 seconds, the screening rate is basically 0, indicating that the screening is basically completed near the end of the screening process.
1. Screen wire diameter: The smaller the screen wire diameter, the more severe the decrease in screen penetration rate.
2. Sieve size of air flow sieve: The larger the sieve size, the more significant the decrease in sieve penetration rate.
3. Screen surface inclination angle: The curve shape of the decrease in screen penetration rate is basically consistent, indicating that different inclination angles have a relatively small impact on screen penetration.
4. For screen width: The smaller the screen width, the greater the decrease in screen penetration rate, indicating that a too small screen width is not conducive to screen penetration.
The above is the treatment method for the effectiveness of the airflow screen. If you have any relevant screening questions or needs and would like to learn more about the product information, please call+86-1323806514, and we will be happy to serve you.
