PRODUCTION OF COMPOUNDS WITH HIGH FILLER OR FIBER LOADING ON SCREW KNEADERS

摘要

The production of filled and reinforced compounds has a high economic importance mainly because fillers and reinforcing fibers render the final product to serve very specific applications. In order to understand such operations more the term "highly filled" will be explained and critical aspects analyzed. In essence two different type of compounding machines are utilized for such compounding tasks, the co-rotating twin-screw and the reciprocating single screw (kneader). Fundamental differences of these systems are analyzed and compared. Examples of compounding processes are described.
