		<title>The Similarities and Differences between Parallel and Conical Twin Screw Extruder</title>
		<description><![CDATA[Similarities:
Both of parallel twin screw extruder and conical twin screw extruder have the transmission mechanism to push forward the plastic compulsorily. The two kinds of extruders also have the nicer ability of mixed plasticization and dehydration. In addition, they have the similar adaptability of molding process for the material and plastic.
Differences:
1. Diameter
