CleanScrape primary – conveyor belt cleaner


CleanScrape primary – conveyor belt cleaner, was invented by Wilfried Dünnwald – ex engineering mining manager at Ruhr Kohle, German and is designed and manufactured by CleanScrape GmbH in Bishofsheim, Germany. The belt cleaner was first introduced to the general market in 2010 and has since established a significant growth in the industry worldwide. CleanScrape primary was given “the most innovative” award at the Bulk Handling Awards Sydney in 2013 in and has since been highly valued by major mining End-Users and other market players. award


Australian Belt Cleaning Pty. Ltd. is the sole importer and distributor, with the assistance of a range of accredited partners, of CleanScrape primary to the Australian and New Zealand markets. Worldwide, the products is distributed by CleanScrape GmbH (Germany), Kubicek (Austria) and Martin Engineering (Europe, South Africa, Russia and near and Middle East)

Working principle

CleanScrape primary – conveyor belt cleaner significantly differs from the competitor’s products as it operates on a 3D diagonal helix around the conveyor discharge pulley opposed to the conventional pole & horizontal configurations.

A series of overlapping tungsten tips provide the scraping effect of the cleaner and are interconnected by steel componentry and moulded into a flexible FRAS approved rubber blade. The blade is held in-place and tensioned through a set of stainless steel ropes running lengthwise through the blade and are attached to a mechanical spring tensioning system located on both sides of the conveyor chute/cheek plates. The mechanical spring tensioners provide a consistent and continuous force on the blade and due to the blade’s diagonal directional cleaning, only very little force is required to achieve an excellent cleaning effect.

Features and benefits
