Product Description

Plastic 3 in 1 EPS PS XPS EPE recycling pelletizing machine

RETECH RCSJ Series compacting and pelletizing system combines functions of compacting, plasticization and pelletizing into one step, applied in the plastics recycling and pelletizing process. RCSJ pelletizing system is a reliable and efficient solution for plastics film, raffia, filament, bags, woven bags and foaming materials granulation.

Working Steps of RCSJ Compacting and Pelletizing System:
 1. Feeding: As a standard design, plastic scraps such as LDPE/LLDPE film, PP filament, PP raffias/fabrics 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 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/Agglomeration: 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.
 4. Melt filtration: Non-stop screen changer, double-plate type, double-piston type, double-piston type with function of back-flush.
You can put different layers and different standard mesh like 80 mesh/120 mesh according to the next application of granules.
 
 5. Pelletizing: Die-face water ring pelletizing system set as the standard granulating method in RCSJ pelletizing 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.
 6. Drying&Vibrating
The plastic pellets/granules will get wet while falling down into cooling water after cutted.The hot pellets is easy to blocking in a short time. Retech have 2 options to help you to get best granules.The first option is to dry the wet granules by vertical dewatering machine.It works by fast centrifuge force in speed 1200 RPM. The granules will get fully flying and water will be get rid of granules fastly. After dewatering machine,we usually put a vibrator machine to select best granules by hole size selection.  
The second option is to vibrating the granules directly and slowly. The graules will stay a while on screen of vibrator to dry.
