The TT-ACS-H series compacting and pelletizing system combines the function of crushing, compacting, plasticization and pelletizing to One step. Applied in the plastics recycling and pelletizing process. TT-ACS-H system is a reliable and efficient solution for plastics film, raffias, filaments, bags, woven bags and foaming materials re-pelletizing.
The TT-ACSS-H series compacting and pelletizing system combines the function of crushing, compacting, plasticization and pelletizing to One step. Applied in the plastics recycling and pelletizing process. TT-ACSS-H system is a reliable and efficient solution for plastics film, raffias, filaments, bags, woven bags and foaming materials re-pelletizing.
The final product produced by the ACSS system is in pellet form and can be placed directly into the production line for the blown film, tube extrusion and injection moulding.
It consists of two sets of Single-Screw Extruders, suitable for printing ink heavy, high moisture content, poor fluidity and temperature-sensitive, high impurity content materials which requires the double filtration system, multiple exhaust and other higher requirements, and a longer process.
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 contrl system, to warn and stop the system, in case that metal is found in feeding.
CRUSHING AND COMPACTING
The rotatory blades of compactor with cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optional 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.
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 34D to 36D 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 water content.
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 quolity of the input material as well as the planned use of granules.
Die-face water ring pelletizing system set as the standard granulating method in ACSS-HTM system. Self-adjusting pelletiziin head for the best granulate quolity and long uptime thanks to consistently correct blades oressure. RPM of rotatory blades is automatic based on melt extruding pressure.
VIBRATION DRY AND PACKING SYSTEM
Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.
