The Advantages and Applications of Polyurethane Screen Plate

Polyurethane screen plate is a kind of mesh screen produced by polyurethane as raw material, which is suitable for screening materials of various nature, as well as coal, gangue, coke, slaked lime and other materials that are wet and easy to block. It overcomes the problem of sticky screen when screening wet materials in various vibrating screens​ and improves the output and reliability of the screening system.

Advantages

Long service life

Polyurethane has a larger modulus of elasticity and high wear resistance and impact absorption, so it has greater strength and its load-bearing capacity exceeds that of rubber screen plates. The service life of polyurethane screen plate is 8-10 times that of ordinary screen plate, 3 times that of stainless steel and 3.9 times that of rubber. It is the material with the best wear resistance.

Wide range of application

It is suitable for any type of vibrating screen and can be customized. Polyurethane screen plate is used to screen various materials from 0.1mm to 170mm.

High screening efficiency

Polyurethane screen surface has self-cleaning property, no pre-clogging and higher screening efficiency. Polyurethane is ideal for sieving and classifying wet and fine materials due to its strong water permeability and large cone angle of the screen holes, which can prevent the bonding of wet particles.

Low working noise

According to the actual measurement, the same screen machine adopts polyurethane mesh plate, compared with metal mesh plate, the noise is reduced by 5-20 decibels, which greatly reduces the dust flying.

Significant economic benefits

The unit price of the screen plate is 2-3 times of the metal screen plate. Considering the screening efficiency, service life and maintenance cost, the overall advantage is better than ordinary screening machine.

High sieving precision

Polyurethane screen plate adopts mold casting molding method, the mesh design is reasonable, the aperture is precise, the screening quality is good, and the size under the screen meets the user's demand.

Low total cost

Although the one-time investment of polyurethane screen plate with the same specification (area) is higher than that of stainless steel screen plate (about 2 times), the total cost is not high, and the service life of polyurethane screen plate is 3~5 times that of stainless steel screen plate, so the maintenance and replacement times are less and economical.

Good resistance to moisture.

Can work under the condition of water as medium. In the presence of water, oil and other media, the friction coefficient between polyurethane and materials is reduced, which is more conducive to sieving, improving sieving efficiency and avoiding wet particle adhesion.

Energy saving and consumption reduction.

Polyurethane has small specific gravity and is much lighter than steel sieve of the same size, thus reducing the load of the screening machine, saving electricity consumption and prolonging the service life of the screening machine.

 

Applications

Mainly used in: power plants, cement plants, mining industry, steel plants, coal washing plants, etc.

 

If you buy from a reliable Vibrating Screen manufacturer, you will find polyurethane screen panels that are developed by professionals using the best raw materials from the ideal suppliers. These panels are made in a highly sophisticated manufacturing cell that is equipped with advanced tools and machines.

How Electric Facial Machine Can Help You Get A Glowing Skin

图片
    Electric facial machines, also known as  facial devices  or skincare devices, have gained popularity for their ability to enhance skincare routines and promote glowing, healthy skin. These devices use various technologies and functions to provide a range of skincare benefits that can contribute to a radiant complexion. Here's how electric facial machines can help you achieve glowing skin: Cleansing: Many electric facial machines come with cleansing attachments, such as brushes or silicone heads. These attachments offer a deeper and more thorough cleanse compared to manual cleansing, removing dirt, oil, and makeup residue effectively. A clean canvas is essential for achieving glowing skin. Exfoliation: Some facial devices have exfoliation features, such as microdermabrasion or gentle peeling modes. Exfoliation helps remove dead skin cells, revealing newer, brighter skin underneath. This process can improve skin texture and promote a radiant complexion. Enhanced Absorption of Ski
