METHOD AND APPARATUS FOR FORMING A SYNTHETIC EXTRUDATE

摘要

A method for forming a synthetic extrudate in a mixing apparatus (10) that includes a pair of screw shafts (16) having intermeshing co-wiping screw sections (18) within a mixing chamber (14) and having conveying portions (57) rotatably cantilevered for self-journaled support within respective conveying chambers (22) downstream from the mixing chamber. Polymeric and organic material is fed into the mixing chamber, the polymeric material is heated to a molten state, mixed with the organic material and degassed while the polymeric material is in a molten state, and the mixture is conveyed downstream through the respective conveying chambers and discharged.
