Updates to Superior Industries’ conveyor belt cleaners decrease required maintenance

Superior Industries, Inc. has made some updates to its Exterra conveyor belt cleaners, which will reduce the time required to maintain the scraping systems.

Superior Industries has made a new fast-acting click tensioner available for the primary and secondary models. After installation, operators twist the tensioning unit to set the proper force. Click count instructions are labelled on the aluminum housing that protects the springs.

Superior's SFL scraper models are now manufactured with a special extruded tube. It's designed to house the patented springs and seal them from fugitive material. SFL means "set for life". Exterra belt cleaners with this SFL option require tensioning just once at the time of installation. Accurate tension is maintained automatically – with no required maintenance – for the entire life of the blade.

Superior's conveyor components engineers recently completed lab and field testing on a proprietary new mix of polyurethane, which is poured into moulds to form the blades. This material is also more flexible and lasts longer, which endures beating from belt splices and wears more effectively. All blades are developed in-house by Superior.

There are several models of Exterra belt scrapers in both aggregate and mine duty constructions. Blade widths are available up to 102 inches (2,590mm). Along with 250 tons of other products, Superior's complete line of Exterra belt cleaners will be shown at CONEXPO-CON/AGG 2023.
