Polyurethane elastomer is a new type of synthetic material between rubber and plastic. The screen mesh has the characteristics of strong wear resistance, wide range of hardness, high elasticity, high bearing capacity, ozone resistance, oil resistance, radiation resistance, and high pit tear strength. Indispensable engineering materials in modern industry, suitable for metallurg, Gold, coal, sand and gravel screening and other industries.

Polyurethane rod screen
It is suitable for metal beneficiation and stone screening.

Polyurethane rod screen is composed of multiple polyurethane rods bonded to each other. The polyurethane rod is lined with steel wire to fix it. It is mainly made of mechanical casting. The production equipment mainly includes stainless steel reaction kettle, two-component casting machine, and vulcanization platform. , secondary vulcanization oven and other equipment, some small screens can also be cast by hand, but relatively high technology is required.

Technical requirements

The installation method of the polyurethane rod screen is mainly the tension test installation. Due to the structural form of the screen, there are tension plates on both sides and steel wires inside. The steel structure performance of the steel plates on both sides is not lower than the mechanical properties of Cr13, and the internal steel wires are spring steel wires. , must have a strong function, not less than 65Mn mechanical properties. Welding materials: ordinary carbon steel T422 electrode, stainless steel electrode for stainless steel.

Appearance quality

The surface of the polyurethane rod should be smooth and uniform, with no broken teeth and ribs. The rubber and metal should be firmly bonded, and there should be no exposed steel bars and glue opening. The bubbles and impurities on the surface of the screen should meet the relevant manufacturer and enterprise standards. Regulation.

Technical parameters

The technical parameters of polyurethane rod screen mesh mainly include important indicators such as mesh size, hole spacing size, mesh wire diameter, and opening rate. The opening rate of the polyurethane bar screen is much higher than that of the polyurethane screen plate screen, and it is not suitable to block materials during work, and the screening efficiency is high.

Performance characteristics

（1）Super wear resistance.
Practice has proved that the polyurethane rod screen is several times that of the steel screen and dozens of times that of the iron screen.
（2）Self-cleaning type, not suitable for hole blocking and high screening efficiency.
Because the polyurethane rod screen maintains high hardness while maintaining high elasticity, it effectively avoids the adhesion of
supermarket particles. What is more unique is its conical structure with a small top and a large bottom, which ensures that the screen is
at the screening limit of the screen. The material will not block the hole.
（3）Since polyurethane is an excellent sound wave absorbing material, it has a good noise reduction effect, and the sound emitted by
the screen machine during normal operation is obviously much smaller than that of the steel screen, which improves the working environment
of the on-site workers.
（4）Due to the light weight of the polyurethane rod screen, the small dynamic load and the small power consumption of the screen machine, the
processing capacity is increased and the productivity.
