A SCREW ELEMENT FOR A CO-ROTATING TWIN SCREW PROCESSOR

摘要

An element (110) for a co-rotating twin screw processor (100), the element (10) having a lead 'L' and at least one continuous flight (12,14,16) helically formed thereon and, wherein the flight (12,14,16) transforms at least once from a first non-integer lobe flight (12,14,16) into a second non-integer lobe flight (12,14,16) in a fraction of the lead 'L' and transforms back to the first non-integer lobe flight (12,14,16) in a fraction of the lead 'L'.
