China PE PP Plastic Pelletizer Extruder

PE PP Plastic Pelletizer extruder
The ACS 800/120 compacting and pelletizing system combines function of crushing, compacting, plasticization and pelletizing to one step, applied in the plastics recycling and pelletizing process. ACS 800/120 is a reliable and efficiency solution for plastics films, raffias, filaments, bags, woven bags and foaming materials re-pelletizing.
Final productions produced by ACS 800/120 are in the form of pellets/ granules, can directly put into the production line for film blowing, pipe extrusion and plastics injection, etc.

Working steps of ACS 800/120compacting and pelletizing system
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 shrinking just below their agglomerating point. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushes, dries and compacts the material which 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 32 to 34D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with some water content.
4. Melt filtration: a regular single-plate/ piston double-station screen changer or non-stop double-plate/ piston four-station can be installed on head of extruder to present significant filtration performance. The requirements on the filter technology depend heavily on the quality of the input material as well as the planned use of granules.
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.

Advantages of ACS compacting and pelletizing system
1. Combine crushing, compacting and pelletizing steps in one system, less-labor cost;
2. Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;
3. Higher output and lower energy consumption.
