Top High Wear Resistance Screw Elements Spare Parts for Plastic Extruder
1 . Gerneral Characture of Bloom's Co-rotating Twin Screw Extruder& Screw Elements
Bloom's twin screw extruder are built on a modular system. Screw elements with different length and function are mounted to the main splined shaft. The screw combination are changeable. Thus, with a few screw elements and barrel variation, different processing tasks can be finished on the same machine. Besides,when part of screw element,liner or barrel wear out, we only need to replace the broken parts instead of replacing the whole screw or barrel. Maintenance cost saves!
