Plastic granule production line combines function of crushing, compacting, plasticization and pelletizing into on line, applied in the plastic recycling and pelletizing process.
Plastic granule production line combines function of crushing, compacting, plasticization and pelletizing into on line, applied in the plastic recycling and pelletizing process. Plastic granule production machine is reliable and efficiency solution for film, raffia, plastic bags, woven bags re-pelletizing. Purui Machinery can special design it according to customer’s demands.
Plastic granule production machine adopt latest advanced technology, design with simple structure and easy to operate, high production capacity, economy energy consumption, reliable performance, etc.
Plastic granule production machine is equipped with gearbox specially-designed for hard tooth face ; 38CrMoALA nitrided screw and barrel; non-stop screen-changer, cooling water tank, blower fan, hob-style granule-cutter. The surface of the screw and barrel has been special treated so that the screw and barrel are wearable, they can have a very good plastification and mixing effect and the production capacity is high. The extruder has the vacuum vented design which can exhaust the vapor or gas during the production, so that the output can be more stable and the pellets are more dense.
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
