Barrier screw of extruder for melt-blown cloth machine

A type of screw that is equipped with a barrier section at a certain position of an ordinary screw to prevent unmelted solids from passing through and to promote solid melting.

Through the mixing action of shear and vortex, this screw converts mechanical energy into heat energy and conducts heat exchange, so that the materials are melted and homogenized, and the radial temperature difference is small, and the output and quality are better than conventional screws.
