Polyurethane sieve plate dehydration effect

Recently, some customers have reported that the previously installed polyurethane sieve has a poor dehydration effect. I want to know what is the reason. Today, the polyurethane sieve manufacturer will take everyone to understand the factors that affect the dehydration effect of the polyurethane sieve.
1. Particle shape. Affect polyurethane dewatering screen
Spherical and plate dehydration factors The bed formed by cubic or polygonal particles has enough voids to be easily dehydrated, while flat particles have large sedimentation resistance and are not conducive to dehydration.
2. When the solid-liquid density difference is small, the possibility of loss of solid particles with the liquid flow increases. At this time, a fixed sieve for dehydration at a relatively slow flow rate should be used.
3. Granularity and granularity characteristics.
The particle size distribution is the most important factor, especially for fine-grained materials. The dehydration effect depends to a large extent on the filter bed initially formed. It is either composed of coarse particles falling on the screen surface, or formed by bridging fine particles on the screen surface. In order to obtain a higher dehydration efficiency, it is necessary to maintain a certain proportion of particles larger than the average particle size. It is generally believed that when the volume solid-liquid ratio is 1:1, the content of particles larger than the average particle size should account for 40%.
4. Material composition.
In the high-frequency dewatering screen, if the content of clay materials is large, the viscosity of the slurry will increase and it will not be conducive to dewatering.
The above is the reason that Dezhou Chaishang Trading Company introduced you to the dewatering effect of the polyurethane screen. If you have other questions about the polyurethane screen, please refer to other content on this site or call for detailed inquiries.
