Trellex Pre-Cleaners ABC 95

Tailor made blades for optimum performance in all applications

Belt cleaning isn’t just a question of esthetics, but rather an important determining factor if efficient, safe and profitable conveying is to be achieved. Metso Minerals has developed a new belt cleaning product range called ABC – Absolute Belt Cleaning. Our goal was to provide technical solutions that gave the products high efficiency, long wear life and a minimal need for maintenance. The new products have been tested for a long time – under tough conditions – and have proven to meet the very high goals we set at the start of the development process.

High efficiency ensures minimum spillage
The parameters that affect the efficiency are, among other things, the scraper to belt contact angle, the contact area and the contact pressure per surface unit. On the new ABC scrapers these values are kept as close to the ideal as possible, throughout the wear life of the blades. Because of that, these scrapers show a constant and very high cleaning efficiency from installation and throughout their wear life. To further increase the efficiency of the scraper, the blades are divided into segments, which can move independently of each other. Reduced spillage leads to less
wear on the conveyor and its components and great clean-up cost savings.

Long wear life for lowest cost per ton
The life expectancy of a scraper is very much dependent upon its efficiency. The more material that passes between the scraper and the belt the higher the wear rate becomes. Thanks to the high and constant cleaning efficiency of our new scrapers the amount of material still adhering to the belt after the scraper can be reduced to a minimum. Consequently its wear life is extended and the cost per ton low.

Minimal maintenance needs for trouble free operation
Since the blade to belt contact pressure remains almost constant throughout the entire wear life of the scraper blade, there is no need to re-tension the spring tensioner and the need for maintenance is reduced to an absolute minimum. The belt cleaning system is designed to operate in a dirty and demanding environment, and the blades are shaped in such a way that build-up of material on the blades is prevented.

High reliability during the entire life of the scraper
The ABC scrapers are made of Trellex’s own polyurethane material, which has outstanding wear properties. Using polyurethane means that an aggressive scraping angle can be used without any risk of damaging the belt. The special design of the new blades means no reinforcing metal parts are needed. The base of the blade is securely held in place in a specially designed aluminum cassette.
