Polyurethane Screen

Description

The polyurethane-block-orbit screen is kind of convenient installment screen which is composed of the framework that is welded in rigidity flat metal, special embedded neck and wear-resistance polyurethane materials covered on the surface of the framework. It is featured of high wear-resistance, tear resistance, high elasticity and long service life (3-4 times than stainless steel screen). In addition to these, the weight of this kind of polyurethane-block-orbit screen is only one-sixth of stainless steel screen, and thus highly reduces the load of screening machine and save a large number of electric power. So this polyurethane screen is highly welcomed by the users. The groove design, aperture, thickness and boundary dimension can be designed according to customers’ machine specifications and requirements to meet the users’ demands.

Applications

The polyurethane-block-orbit screen is mainly used for screening and sculting of medium and small granularity materials in coal dressing industry, water conservancy and hydropower sand system and other industries.

Advantages

1. This kind of polyurethane screen is featured of high wear-resistance, tear resistance, high elasticity and long service life (3-4 times than stainless steel screen). In addition to these, the weight of this kind of polyurethane-block-orbit screen is only one-sixth of stainless steel screen, and thus highly reduces the load of screening machine and save a large number of electric power.
2. It has the characters of self-clean performance, no stuck and high screening efficiency. As the polyurethane has strong water permeability and the taper angle of the sieve pore is very big (140°) which can effectively avoid the adherence of the small wet material, so it is suit for the screening and classification of wet material. In addition to these, our polyurethane screen adopts the imported raw material, so the well tensioned performance of the elastomer itself can also effectively avoid the phenomenon of plug hole. Above for these features, our polyurethane-block-orbit screen has obvious economy benefit.
