- The highest open area urethane screen available – from 0.25 inch (6.2 mm) to 325 mesh (45 μm).
- The development of fine mesh, high open area, urethane screen surfaces is perhaps one of Derrick’s most notable contributions to science of fine particle separations for both wet and dry applications. While all urethane screen panels are well known for their abrasion resistance, only Derrick® Polyweb® screens combine long life with high open area, capacity, and performance rivaling that of conventional woven wire screens. Moreover, its anti-blinding properties now make it feasible to screen materials previously considered difficult or even impossible to screen.
- Processing plants throughout the world have demonstrated significant cost savings through the use of Polyweb screens. It’s not uncommon for Derrick urethane screens to last 6 to 18 months, 10 to 20 times longer than conventional woven wire panels. They are also lightweight and easy to install.
- With openings as fine as 325 mesh (45 μm) and open areas up to 45 percent, Polyweb screen surfaces are suited to a wide variety of wet and dry applications.
- Derrick has developed this Polyweb screen technology totally in-house. From the design and development of intricate molds, to the unique production equipment needed to manufacture panels on an economic scale, Derrick has again proven itself as the world’s leader in fine screening technology.
- A broad range of panel openings are currently available to fit screening machines manufactured by Derrick. Yet, the design and manufacture custom molds, and even urethane formulations, is an ongoing process. Where a specific opening or preferred panel design is not available, can be developed. In all cases, a Derrick engineer will work closely each application to determine the appropriate panel and to address issues such as chemical compatibility or temperature.
