For the pre-separation in recycling plants for products which are difficult to screen, cascade screens are increasingly used. The advantage is that they screen with less pegging and can remove long parts. The finger cascade screen works on basis of a circular vibratory screen with high acceleration, generated via JOEST shaft drive.
Due to the high acceleration values with the conical opening finger screen system in cascade shaped arrangement – there is firstly a breaking up of the material and secondly a screening with comparatively few blockages. For best separation results, our finger cascade screens are equipped with an impact bottom for optimal product distribution and with additional falling steps.
