The development of fine mesh, high open area, urethane screen surfaces is perhaps one of Derrick’s most notable contributions to the science of fine particle separations. While all urethane screen panels are well known for their abrasion resistance, only Derrick’s patented urethane 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 Derrick urethane screens. It’s not uncommon for Derrick urethane screens to last 10 to 15 times longer than conventional woven wire panels. They are also lightweight and easy to install.
With openings as fine as 200 mesh (0.075 mm, 75 microns) and open areas ranging from 35 to 45 percent, Derrick urethane screen surfaces are suited to a wide variety of wet and dry applications.
Not available from any other manufacturer, Derrick has developed this proprietary 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 of custom molds, and even urethane formulations, is an ongoing process. Where a specific opening or preferred panel design is not available, one can be developed. In all cases, a Derrick engineer will work closely with each application to determine the appropriate panel and to address issues such as chemical compatibility or temperature.
