Technology tapered openings that reduce blinding and pegging. This makes the material a good choice in higher wear areas in both wet and dry applications, but these positive characteristics traditionally come at the expense of open area. Woven wire — At the other end of the spectrum is woven wire. It is commonly referred to as wire cloth or wire mesh screen, and it comes in a variety of alloys, weave types, and diameters. Woven wire offers some of the greatest open area and can be used for a wide range of applications. It also is known to make the "cleanest" cut when referring to accuracy. These strong advantages come at the expense of wear life, but fortunately not all woven wire is the same. When selecting woven wire, wire with very high-in-carbon content allows for optimum characteristics in tensile strength and ductility. Hybrid screens — The newest screen media technology is hybrid screens. Hybrid screens combine the excellent wear-life characteristics of polyurethane with the great open area of woven wire cloth. This combination lasts up to six times longer than traditional wire cloth, but offers as much as 80 percent more open area than modular polyurethane. The hybrid's tapered openings either accept or reject near-size material to provide a self-cleaning effect, which eliminates nearly all blinding and pegging. The result is a screen that is extremely durable and highly productive. Self-cleaning screens — Self-cleaning screens combine individual wires using flexible polyurethane strips, allowing the wires to move at frequencies higher than the G-force generated by the vibrating screen and eliminating blinding and pegging. The unique design of flat lying wires even offers higher open area than woven wire, while outlasting it by up to 25 percent. Through careful attention to the various phases of screening, a thorough analysis of the site's needs, and use of the right mix of media, an operation can extend screen life, reduce downtime, and improve production of high-quality products. AM Florian Festge is the president of W.S. Tyler Canada, where he is responsible for coordination of strategic and operational efforts within the company's screening media and vibrating screen divisions. He is a business administration graduate of the Technical University of Dresden and has a master's degree with a focus on innovation management and production.
