Twin screw extruder with a material homogenizing unit
Twin screw extruder with a material homogenizing unit
A twin screw extruder with a material homogenizing unit is the subject of this disclosure. Two extruder screws are located within a housing positioned and configured so that screw turns and screw lands of a first screw mesh with respective screw lands and screw turns of a second screw. A homogenizing zone housing is connected to the dual cylinder housing. Two cell rotors are connected to respective extruder screws and are located within the homogenizing zone housing. A plurality of radially distributed cell walls may be disposed on each cell rotor defining a plurality of open conveyor cells where the cell rotors and cell walls of each rotor are configured to mesh a cell wall with an opposing conveyor cell. The cell walls may be arranged with a slope differing from a slope of the twin screw extruder manufacturer. The cell walls may be arranged parallel to or at an angle to an axis of said cell rotors.
1. Field of the Invention
The invention relates to twin screw extruders and more particularly to an extruder for continuous processing of PVC powders.
2. Description of the Related Technology
Twin screw extruders are continuously operating screw presses with two meshing screws and are used to plasticize and extrude plastics. Twin screw extruders are used preferably for the continuous processing of PVC powder formulations.
Twin screw extruders may be divided into different zones which are distinguished. A melting zone, a mixing zone, a degassing zone and a discharge zone may be arranged in line from a screw extruder inlet to the outlet. As a rule, the screws have different configurations adapted to the particular zone, over their length. The screw turns may have different pitches and spacing in the zones and may be provided with interruptions, baffles or the like. The screw turns may be replaced by meshing toothed disks or kneading blocks particularly in the melting and/or the mixing zones in order to obtain a particularly intensive mixing of the powder in the melt and to homogenize the melt. The screws usually have continuous screw turns in the discharge zone which mesh with slight roll and flank clearances, thereby preventing any back flow of the melt and producing the necessary pressure for pressing the melt into a molding tool attached to the extruder.
