PP / PVC / PET recycle granulation production line

1. single screw extruder suitable for mostly plastic to make granules :

such as : PP PET PP PS ABS EVA(no foaming) TPU(but parallel twin screw much better) PA , there is a pre-condition is : single
screw extruder only use to common recycle waste plastic to be granules, if want to make function master batch with adding
additives, twin screw extruder is the best.2. Conical screw extruder suitable to make PVC granules only. because its short screw and barrel, can avoid PVC burning , because
PVC material’s special characters.
3. parallel twin screw extruder suitable to make

++filling modification : PE PP EVA ABS PC PS +Caco3, Talc powder , barium sulfate, aluminum hydroxide magnesium hydroxide SiO2,
etc.
++ blending modification (rubber and plastic compounding , plastic alloy)
Such as : PP PE PS +SBS PP PA+EPDM POE PP+NBR EVA+SILICON ABS+TPU PC+ABS etc.
++ color master batch : PE PP EVA PS PBT PET + color and other additives
++functional granules such as Degradable granules : PE PS PP+starch , anti firing granules : PP PE PA ABS PBT+ fire retardant.
Carbon black , fiber , and other special use granules . like PBT AS PA PC POM PPS PEEK PPO PES +FIBER .
++thermoplastic elastic material like TPR TPU TPV SEBS SIS .
++ varies cable material like HDPE LDPE LLD PE MDPE PP EVA insulation materials , crosslink material .
++ other reactive , devolatilization and powder coating material

4. Double stage extruder suitable to make foamed material recycle like foam PE sheet , foam PS sheet. Also can use to recycle
film to be granules .

With side compressor extruder special use to recycle film . because film is light and thinner , not easy to feeding to extruder
feeding hole, compressor can force the film into the screw directly . this function similar as side feeding system with screw .

what’s cutting method suitable for you:
1、water cooling strand cutting system
Machine consist of extruder , screen changer, mould , water cooling tank , air blower and cutter unit.
This cutting system suitable mostly material’s cutting

2 、air blow cooling hot cutting system
Consist of feeding system , extruder, air cooling hot face cutter, cyclone , and vibrating sieve.

Applications : enforcing modification material such as PE , EVA etc +caco3, talc, TIO2, PP PVC , CARBON BLACK , degradable master
batch like PE PP +starch , additives . and anti flame master batch such as PE EVA+SB2O3, MgOH2, AL2OH3 etc.
3、water ring cooling cutting system
Consist of feeding system , extruder, water-ring granulator , centrifugal dewatering , vibration sieve container . This cutting
system cut tablet shape pellets , material can be PE EVA etc filled with CACO3, talc TIO2, carbon black ,etc, cable sheath , cable
insulation, compounds of LDPE , HDPE LLDPE or MDPE. Radiation cross link material, heat-shrinkable material, cable compounds, hot
melt adhesives , color master batch and other degradation material.
4、underwater cutting system
The pelletizing currently is the special and innovative technique for the production of high-quality plastics pellets, is used to
produce marketable pellets having very low viscosity and high elasticity , or having special shape requirements such as
micro-particle shape, ball shape , this is very difficult to perform by strand cooling cutting and water ring cooling cutting
system.
Example : TPU EVA PA PP TPE TPV TPR TPEE PA series , PC PET PBT PE POM EPDM, etc.
