Features of Twin Screw Extruder

Twin screw extruder is characterized as follows: higher speed and in the mating area (in the cross-section of the overlapping part of two screws) there is relative velocity, it can produce a strong uniform shear; Geometry determines that it must be open for its vertical flow channel, so that there is materials exchange between the two screws. In exchange, materials at the bottom of a screw slot will move to another screw at the top of the spiral groove. The opening up of the vertical flow make it possible for horizontal flow channel to be open,which is to achieve the exchange of materials between adjacent slot of the same screw. This makes the twin screw extruder with a good ability of distribution and mixture, so it is the most suitable machine for mixing operations.
