Superior Unveils First Ever Primary and Secondary Scraper with One Mounting Point


June 7, 2011

Morris, MN – Superior Industries, a leading manufacturer of conveyor systems and components, released the market’s first ever primary and secondary belt cleaning system– sharing the same, common mounting point. With one pole, maintenance workers can avoid adding to their conveyor’s structure, a common task to accommodate secondary cleaners. Another key feature is the Exterra® SFL Dual Belt Cleaner’s unique tensioning system – the patented design creates a pressure that is set once, for the life of the blade, during installation.

The company’s Exterra® 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. When left unchecked, carry-back causes material buildup on idlers, pulleys and other components – a problem that causes mis-tracking or belt damage. More importantly, carry-back creates unwanted fugitive material piles under the conveyor.

The primary scraper is equipped with Superior’s Exterra Primary Belt Cleaner. Packed with more urethane, the blade has one of the bulkiest profiles of any primary scraper on the market. Mounted to the same pole as the primary, the secondary cleaner is available in either AR steel (STD) or tungsten carbide. It is designed with segmented blades to withstand vibration and impact from belt splices during operation.

Superior designs and builds its new Exterra SFL Dual Belt Cleaner to accommodate head pulleys with diameters of 12-inches to 20-inches and belt widths of 18-inches to 60-inches. Later this year, the company plans to expand the one-time tensioning unit to accommodate pulley diameters up to 30-inches.
