The Rota consists of a ring-shaped scraper element lying firmly at the lower belt and is set into rotation by the movement of the conveyor belt. Furthermore the Rota is extremely gentle to the belt. According to operational requirements the scraping edge can consist of polyurethane with different shore hardness or ceramic.
The Rota is pressed against the belt by two threaded spindles (right and left). Following, the circular scraping element is set in a slightly inclined position.Due to the rotary motion, the scraper remains flat and wears evenly. By rotation, the scraper hits the belt in a different angle and removes the adhesions. Even using a clamp connection on conveyor, the Rota retains its functioning.
The maintenance effort for the Rota is very low. Also cleaning is usually not needed. A simple visual inspection should be performed on a regular base. Worn scraper elements or ceramic tapes must be replaced.
The positioning of the conveyor system is made at the lower belt according to the localities.
According to operational requirements the scraping edge can consist of different materials.
