The innovative belt cleaning system received the Australian Bulk Handling Award in the Innovative Technology category in 2013 for its claimed design and potential benefits, which include low belt wear, extended service life, reduced maintenance and improved safety, said to ultimately deliver lower cost of ownership. It has been proving itself in a wide range of applications, such as mining, coal handling, quarrying, cement, scrap and other material bulk handling operations.
Unlike conventional belt cleaners that are mounted at a 90 degree angle to the belt, the CleanScrape Cleaner is installed diagonally across the discharge pulley, forming a three-dimensional curve beneath the discharge area that conforms to the pulley’s shape. The novel design incorporates a matrix of tungsten carbide scrapers and is tensioned lightly against the belt to prevent damage to the belt or splices. Despite extremely low contact pressure between belt and cleaner, it has been shown to remove as much as 95% of potential carryback material. The innovative approach has been so effective that, in many operations, previously crucial secondary belt cleaners have become unnecessary, saving further on belt cleaning costs and maintenance time.
The CleanScrape Cleaner protects the belt with its specific application of low force and is ideally suited for both slow and fast conveyor belts, including those with mechanical splices. With its compact size, the design is an excellent solution for areas with restricted space. It can be located either inside or outside of the transfer chute, and the straightforward installation typically requires less than two hours.
CleanScrape Cleaners are generally sold in three sizes: S, M, and L, which cover drum diameters from 270mm to 1250mm and belt widths from 300mm to 2800mm. Each size is available in four different carbide metal grades to suit specific materials and belt structures, one of which is a carbide formulation developed for use on mechanically spliced belts.
Emerging from the company IBS Industriemaschinen-Bergbau-Service when founded last year, CleanScrape is part of Schmittgruppe, a fourth-generation, family-run business with headquarters in the northern Bavarian town of Bischofsheim an der Rhön.
