The product to be screened is fed onto the roller disc star screen, for example via a conveyor belt, distribution screw or vibration chute. Depending on feed requirements, the screening machine is equipped with various fittings. For example, screening to three different grain sizes is also possible. The screening machine is driven by one or more gear motors, depending on the design.
If required, the speed can be adjusted via a frequency converter. The individual screening rollers are connected to each other by chains. In the case of more than one gear motor, screening can be carried out at different speeds. This ensures precise screening of the material along the complete length.
The shafts with the stars or disc can be replaced individually and access is possible via a large maintenance opening.
The machine sorts bulk materials and difficult-to-screen materials into different grain sizes through its variable screen design. The products should not exceed a certain moisture limit. Use our technical centre for practical tests as a basis for selecting the required machine size.
