LFM Harp Wire from Major Wire Industries Limited helps aggregate operations increase throughput over standard harp or piano wire while reducing downtime caused by worn wire cloth, according to the company. Standard harp or piano wire screens use hard metal or plastic slides to hold the wires in place at the crown bar. The wires vibrate against the slides, which in turn vibrate against the crown, causing breakage. Major Wire’s high-performance LFM Harp Wire is manufactured with straight wires firmly molded into polyurethane strips that hold the wires in place at the crown bar. With its wires embedded into flexible polyurethane strips instead of rigid slides, LFM Harp Wire eliminates this steel-on-steel wear. The polyurethane strips at the crown bars keep the wires equally tensioned, creating better wire vibration when compared to traditional harp or woven wire cloth, reducing blinding and increasing production of a cleaner aggregate product. In addition, LFM Harp Wire’s long slots (up to 12 in.) provide more open area to increase screen capacity. Because of its unique design, LFM Harp Wire handles high-impact loads better and lasts up to twice as long as conventional harp and piano wire, the company said. Additionally, LFM Harp Wire screen media is available in custom configurations to match unique screens and applications.
