Circular screen feeder

With its circular screen feeder (SRB) Petersen Service offers an innovative drive concept. The machine does not need a large gear and is equipped with wear parts in the screen basket and scraper arm that are completely replaceable.

Standard gear drive motors that are also used for wind power plants are synchronized via a gearing bearing. They ensure the long-term operation of the system.

The wear parts of the circular screen feeder that are completely replaceable, in particular the screens on the swivel-out screen carriers, can be replaced within the shortest time. The scraper arm which is coated with wear parts is unique. There is no need for an elaborate disassembly of the arm for subsequent hardfacing. Due to the additional installation of stone collecting bags the machine can also be used as a crushing mixer with screen.
