Device for pretreating and then plastifying or agglomerating plastics |
摘要 |
An apparatus for pre-processing and subsequent plastification or agglomeration of synthetic plastic materials, in particular thermoplastic waste plastics for recycling purposes, has a receptacle ( 1 ) in which at least one comminuting tool ( 6 ) circulates. The housing ( 7 ) of a screw ( 8 ) is connected to the receptacle ( 1 ). The diameter (D) of the receptacle ( 1 ) has the following relationship to the screw diameter (d): <?in-line-formulae description="In-line Formulae" end="lead"?>D=10.{square root over (K.d<SUP>2</SUP>)}, wherein <?in-line-formulae description="In-line Formulae" end="tail"?> D is the inner diameter of the receptacle in mm, d is the screw diameter in mm and K is a dimension-less constant which amounts to at least 190. Thereby the dwell times of the synthetic plastic material within the receptacle ( 1 ) are kept at optimal values. |
