The vibrating screen is a high-precision fine powder screening machine, which can remove impurities, classify and filter materials. Can sieve powder materials, liquids, etc. But not every material has a high penetration rate, so how to improve the screening efficiency?
1. Increase the opening rate of the sieve plate. A high opening rate is beneficial to improve the screening effect; usually, the stainless steel woven mesh has a higher opening rate than the welded sieve plate, which can improve the screening efficiency;
2. Adjust the feeding method. In most cases, the feeding is not along the width of the full screen, causing the screen surface to not be fully utilized and affecting the screening efficiency. Add a distributing device at the inlet to make the material evenly distributed;
3. Reduce the hole rate of the sieve batter, and the automatic cleaning device can reduce the probability of blocking holes on the screen surface and improve the screening efficiency, such as bouncing balls;
4. By adjusting the inclination angle of the screen machine, appropriately reducing the inclination angle is beneficial to reduce the thickness of the material and realize the screening of thin materials;
5. Wet screening (screening with the help of washing with water), which is an effective means to improve and improve screening efficiency;
6. For specific vibrating screens such as circular vibrating screens, the method of adjusting the counterweight can be considered to improve the screening effect;
7. Dry sieving requires strict control of the incoming water content. When the water content is high, you can consider batching sieving.
The above methods can usually effectively improve the screening efficiency of the vibrating screen, and users should consider comprehensively according to their own use. It can be used in a variety of ways at the same time, or you can choose one according to your own materials or production conditions.
