Definitions

  • the invention relates to a device for dewatering and drying shredded plastic waste, with a rotor arranged in an elongated housing with distributed over the rotor circumference and staggered in the rotor longitudinal direction Gutleit- and air suction devices and within the housing enclosing the rotor at a distance with the outer diameter of the rotor a sieve basket forming an annular gap, the plastic waste within the annular gap being able to be transported from one housing end with bulk material inlet to the other housing end with bulk material outlet by the effect of the rotor rotation, and with a device for supplying air into the annular gap for drying the plastic waste.
