The polyurethane screen panels are a kind of of screening mdeia that made of polyurethane raw material. Which is also called polyurethane sieve plates.
Sieve hole type: bar seam, square, round, rectangular.
Application industries: coal washing plant, coking plants, mines, power plants, dredging companies, metallurgy, petroleum, petrochemical and other enterprises.
Main application equipment:dewatering vibrating screen, dewatering screen.
The latest production technology is adopted to made polyurethane screen panels have novel structure, convenient installation and disassembly. LZZG polyurethane screen panels are widely used in metallurgy, mining, coal, building materials, water conservancy, road building and other industries on the screening machine. And PU screen panel is the replacement product of steel punching mesh, steel woven wire mesh, stainless steel sieve plates and rubber sieve plate.
Performance of polyurethane sieve plates
The screen surface with self-cleaning performance, not blocking and high screening efficiency. Because the strong permeability, large cone angle (140) of sieve pore can effectively prevent moist fine particle adhesion,so it is suitable for the classification and screening fine moist materials.
LZZG polyurethane screen is suitable for screening the various materials within the scope of 0.1mm-170mm, regardless of dry sieving or wet sieving will not affect the screening efficiency, especially for 0.5mm-3mm dehydration andsculting, the advantages of polyurethane sieve is showed more fully.
Polyurethane screening surfaces have been in use for many years and have proven to be generally economical due to the long wear life and low maintenance requirements.
The extended life is attributed to the SUPERIOR CUT, TEAR AND ABRASION RESISTANCE of polyurethane. The wear life is enhanced by the polymers flexibility, which returns some of the impact energy imparted by the vibrating media.
Correctly applied Polyurethane screens can reduce or even eliminate plugging, pegging and blinding problems due to the tapered openings and resiliency of the material.
Corrosion and rust out are eliminated as Polyurethane is impervious to most elements found in any screening plant.
Aperture shapes are almost unlimited. While wire cloth is typically limited to squares and rectangles, polyurethane screen apertures can be molded to any shape which best serves the particular application.
The polyurethane tension mat, is a single piece screen section utilized to replace wire or perforated plate screen panels fitted with a hooked edge to facilitate clamping onto the vibrating deck support structure.
A tension mat is molded in large sections, typically in the same width and length as the metallic system being replaced.

The mat is reinforced with internal cables, rods or bars for strengthening and to provide a means for applying tension.
Installation of a tension mat is very similar to the procedure for installing a woven wire or perforated plate screen section.
Virtually no deck modifications are required with a tension mat as it installs over the existing crown bar deck allowing quick changeover to a new mat or a metallic screen panel.
A tension mat is "one large piece". Screens do not wear evenly. Once the high wear areas have worn through the ENTIRE MAT must be replaced. Replacing a mat which is worn or damaged in small areas is a very expensive proposition....as large areas of the mat which still offer useable life must be discarded.
The tension mat is custom manufactured to your specifications, typically requiring long lead times. Once manufactured, changes in the openings necessitated by the application are out of the question due to the nature of the one piece screen.
The Modular System is comprised of a multiple of screening segments installed on a special support frame that accepts locking attachments to hold the modular screening segments.
With this type of system individual segments may be relocated on the screen surface as required to equalize wear across the entire screen.
Unlike the Tension Mat, a modular system can be conveniently field modified to accommodate a multiple of different specifications on one screening surface.
Modular systems are interchangeable providing usefulness of the individual modules throughout the screening plant on any deck fitted with a similar modular frame.
One the deck has been altered you CANNOT revert back to wire cloth or perforated plate without costly deck changes or expensive fitments which are labor intensive in installation.
Although individual modules can typically be replaced in minutes, a complete change out can require several hours of intensive labor. Modular systems are NOT SUITABLE where specification changes are frequent.
The Flowmax support frame is lightweight and can easily be installed and tensioned, just like a woven wire screen, in minutes.
Changing out the complete system is the same procedure as used for wire cloth, loosen the tension bolts, remove the clamp rail and lift off the system.
Individual FLOWMAX modules can be changed out in SECONDS, there are no loose parts, the locking system is integral to the modules.
