AN EXTRUSION METHOD, AN EXTRUDER AND A PRODUCT PREPARED WITH THE METHOD

摘要

An extruder having at least one conical stator and at least one rotatable conical rotor. The rotor is mounted from its widest point with first and second bearings in such a way that the first bearing receives the forces acting in one axial direction of the rotor and the second bearing receives the forces acting in an opposite axial direction of the rotor. A method for using the extruder involves feeding a material to the extruder between the rotor and stator and rotating the rotor to cause the extruder to extrude the material.
