Polyurethane Tensioned Screen

Description

The polyurethane tensioned screen is a kind of new machine screen that composed of the framework and the polyurethane elastomer covered on the framework. The steel framework is formed by the lift and right bent hook metal which pass through the bolt and heart tier to connect into a whole structural framework. This new tensioned screen owns high aperture ratio, effective screening, screening accurate, high wear-resistance, better tearing property and long service time and so on. The hole design, aperture, thickness and boundary dimension of the PU screen can be designed according to customers’ machine specifications and requirements to meet users’ demands.

Applications of this PU Screen

This new tensioned screen applied widely in metallurgy, mineralogy, water conservancy and dinas for heavy and light materials’ screening. The mesh size of the tensioned polyurethane screen is 0.08-180 mm, and now it is an ideal sifter material in the world.

Application Cases of our Polyurethane Tensioned Screen


The use scene in the eighth construction bureau of China’s water conservancy electricity
The use scene of tensioned PU screen in Xiangjiaba hydropower station

The Sketch


Advantages

1. This kind of polyurethane tensioned screen has large carrying capacity and long service life.
2. It owns high screening efficiency due to its self-cleaning ability and thus make the holes won’t be stuck. 
3. The polyurethane tensioned screen has wide range uses, so it suits for any kinds of vibration machines and can be made according to the customer’s requirements.
4. Our PU screen adopts the manufacturing technique of mould pouring molding, so its pore size is accurate, the quality of screening is high, which make the particle size of material under the sieve can well conform to customer’s requirements.
5. We provide the polyurethane tensioned screen with the characters of light weight, convenient installment, and convenient replacement of maintenance; it suits for any kinds of screening machines, highly reduces the workload and has significant economic benefits.
6. This new tensioned screen has low operating noise and conforms to the specifications of the environmental noise standards in our country.
