Superior Industries has released what it says is the market’s first primary/secondary belt cleaning system sharing a common mounting point. With only one pole needed, the Exterra SFL dual belt cleaner system eliminates further additions to a conveyor’s structure—a step commonly required to accommodate secondary cleaners. Another key feature is the unique tensioning system that applies a level of pressure set only once, for the life of the blade, during installation. According to the company, the SFL dual belt cleaner is designed to nearly eliminate material carry-back from the top cover of conveyor belting after it passes over the head pulley. The primary scraper is fitted with Superior’s Exterra primary belt cleaner. Mounted to the same pole as the primary, the secondary cleaner is available in either AR steel or tungsten carbide. It is designed with segmented blades to withstand vibration and impact from belt splices during operation. The Exterra SFL dual belt cleaner can accommodate head pulleys with diameters of 12–20 in. (305–508 mm) and belt widths of 18–60 in. (457–1524 mm). Later in 2011, the company plans to expand the one-time tensioning unit to accommodate pulley diameters up to 30 in.
