Under-belt scrapers are devices used to clean and protect conveyor belts. Rosta’s tensioners installed on both sides provide an automatic tensioning system that guarantees ideal blade pressure on the belt. The blades are made of polyurethane or tungsten carbide. They ensure long trouble-free operation.

Benefits of the scrapers:

• minimization of product loss
• no interruptions in conveyor operation due to the need to clean the area around
• less usage of the conveyor belt
• no loss of conveyor productivity
• increase in the service life of the rollers and conveyor drives

The scrapers consist of mounting plates, beam handles, Rosta tensioners and blades.

They are used mainly in the mining industry, aggregate mines or gravel pits. They are also successfully used in cement factories, recycling factories and wood industry (in sawmills).

Pollution caused by the lack of use of under-belt scrapers can lead to a threat to the safety of employees and the environment. This is a solution that is simple, cheap and effective. The blades, also called scrapers, can be made of polyurethane or tungsten carbide.
