Plastic recycling granulating line is special equipment for the POF CPP OPP BOPP film recycling granulating.
Plastic recycling granulating line is special equipment for the POF CPP OPP BOPP film recycling granulating. Plastic granulating line is equipped with comacting machine which cound pre-compact the film into smaller granules, then easily feed into screw barrel of extruder, its efficiency is high and can improve production capacity and save labour cost.
Plastic granulating line has two vacuum exhuasting mouth on extruder barrel which can fully vent the moisture in the material and hence the final granule quality will be very perfect.
At the end of screw barrel, plastic granulating line is equipped with double post fast speed hydraulic non -stop screen changer which can effetively filt out the dirty in the plastic melt.
Plastic granulating line adopts water ring pelletizing which is easier to operate, and the shape and appearance of granule is good.
The control system of the plastic granulating line includes a heating system, a cooling system, and a process parameter measurement system, which is mainly composed of electrical appliances, instruments and actuators (ie, control panel and console). Its main function is to detect and adjust the temperature, pressure and flow rate of the plastic in the extruder; to realize the control or automatic control of the entire unit.
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.
Compactor / Agglomerator
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.
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
