1. Feeding: as standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls' scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor's room is. Metal detector can be combined with belt conveyor, and can interlock with control system, to warn and stop the system, in case that metal is found in feeding section.

 

2. Crushing and compacting: the rotatory blades of compactor will cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrink. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushing, drying and compacting the material enables a fast and stable feeding from the compactor directly into the extruder.

 

3. Plasticization and degassing: A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiently, especially suitable for heavy printed film and material.

 

 

5. Pelletizing: die-face water ring pelletizing system set as the standard granulating method in ACS system. Self-adjusting pelletizing head for the best granulate quality and long uptime thanks to consistently correct blades pressure. RPM of rotatory blades is automatic based on melt extruding pressure. Advanced dewatering vibration sieve combining with horizontal-type centrifugal dewatering present high performance dried pellets.
