The plastic recycling pellet machine is developed and improved by Purui Machinery after years of development and improvement to meet the needs of small processing plants and truly realize one machine with multiple functions.
In the recycling process of waste plastics, the waste plastics need to be cleaned and dried, then melted and plasticized by the screw extruder of the plastic recycling pelletizer, extruded into strips, then cooled by cooling equipment, and finally cut into pellets by a pelletizer. Particles, these particles are further processed into various plastic products through blow molding, injection molding, calendering and other processes.
1. The plastic recycling pelletizer can adopt single-screw and twin-screw according to the user’s requirements or the characteristics of the return material, and the style can be single-stage, double-stage, etc.
2. Plasticized and granulated polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (pvc), PET, HDPE, ABS and other engineering plastics or general plastics are recycled and pelletized.
3. The cutting method can be selected: water ring cutting, strip cutting and so on.
Normal:
| Model | SJ45 | SJ65 | SJ90 | SJ100 | SJ120 |
| Output(kg/h) | 10-60 | 100-150 | 180-250 | 250-350 | 300-600 |
High output,low consumption:
| Model | SJ150 | SJ160 | SJ180 | SJ200 |
| Output(kg/h) | 400-700 | 600-1000 | 1500-2000 | 2000-3000 |
Belt Conveyor
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.
Extruder
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 efficiency, especially suitable to heavy printed film and material with water content
Water-ring Die-face cutting system
Water-ring die-face/Strand cutting methods are usually adopted. In water-ring die-face cutting system, the rotary cutting blades will be pneumatically fit completely and closely to the die-face surface to ensure efficient cutting. Rotary speed of the blades is automatically adjusted by module system according to melt pressure at the die face.
Vibration drying system
Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.Combine crushing, compacting and plletizing steps in one system, less-labor cost.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;Higher output and lower energy consumption
