What methods are used to reduce the paste rate on the trommel screen surface?

 There are certain differences between the drum screen and the vibrating screen. It has a large screening capacity and a large contact area with the materials. However, during the screening process, some materials that are easy to stick to the mesh will increase the mesh coverage rate of the screen surface. Let's take a look at some methods. It can reduce the paste rate of the screen surface.

    1. Generally, the higher the opening rate of the sieve plate, the better it is to reduce the paste rate on the screen surface;

    2. The inclination angle of the trommel screen can reduce the paste rate of the screen surface to a certain extent, and a certain inclination angle can be set according to the screening output and material properties.

3. Appropriately adjust the screening parameters: By adjusting the rotation speed, feed amount, amplitude and other parameters of the trommel screen, the residence time of particles on the screen surface can be reduced, the short circuit phenomenon can be reduced, and the mesh paste rate can be reduced.

4. Clean the screen regularly: Clean the blockage on the screen regularly to prevent particles from adhering to the screen and increase the screening resistance and mesh paste rate. You can use tools such as brushes and water guns to clean the screen.

5. Use an appropriate mesh size: According to the size range of the particles to be screened, select an appropriate mesh size to avoid excessively small or large meshes that may cause particles to easily accumulate on the screen.

6. Optimize screening conditions: Reasonably control screening conditions such as feeding speed and feeding uniformity, maintain appropriate humidity, avoid adhesion and accumulation between particles, and reduce the paste rate.

7. Use screen auxiliary devices: Install some auxiliary devices on the screen, such as ball washers, scrapers, etc., which can effectively clean the particles on the screen and reduce the paste rate.

It is necessary to choose a suitable method to reduce the screen paste rate according to the specific drum screen model and material characteristics.
