Máquinas de Granulador de Plástico para Reciclagem e Regrind In-House
Wet, rigid, vertical, PET-bottle and integrated
shredder-granulator machines from 100 kg/h to 2,000 kg/h. SKD-11 blades, custom screen sizes,
direct from the manufacturer.
O que faz uma Máquina de Granulador de Plástico e onde ela se situa na sua linha
UM granulador de plástico reduces scrap — runners, sprues, defective parts, bottles,
film, pipe, sheet — into uniform regrind granules (typically 4–18 mm) ready for direct extrusion,
pelletizing, or resale. Where a shredder tears large items into coarse strips at high torque and
low rpm, and a pelletizer turns molten polymer into round pellets, the granulator is the precision
size-reducer in between: high-speed rotors (400–800 rpm), tool-steel blades, and a sizing screen
that defines final particle size. For injection-molding shops, a beside-the-press granulator
reclaims hot runners in-line. For recycling plants, a central granulator downstream of a shredder
produces the regrind that feeds a washing line, extruder, or pelletizer. Choosing the right
granulator — rotor diameter, motor power, blade steel, screen size, wet or dry — sets the ceiling
on your throughput, energy cost per kilogram, and regrind cleanliness for the entire line. See
shredder vs. granulator vs. pelletizer for how the three
machines differ, or read how a plastic granulator works for the mechanics. Planning a

Como escolher o Granulador de Plástico certo em 4 perguntas
1. Qual é sua matéria-prima?
Bottles & film → wet or PET-flake granulator. Rigid lumps & purging → heavy-duty rigid.
Long pipe & profile → vertical. Mixed / unsorted bulky → integrated shredder-granulator.
2. Qual capacidade de produção você precisa?
Beside-the-press reclaim: 50–200 kg/h. Mid-scale recycling: 300–900 kg/h. Central plant:
1,500–2,000 kg/h. Size 20% above peak to protect the motor.
3. Qual tamanho de regrind você precisa?
Alimentação para extrusora: 6–10 mm. Linha de granulação: 8–14 mm. Revenda como grão: 10–18 mm. Veja nossa
guia de tamanho de peneira.
4. Matéria-prima suja ou limpa?
Clean scrap → standard D2 or SKD-11 blades. Labeled bottles, film with sand → wet granulator +
stainless hopper. Glass-filled / fiber-reinforced → CPM-10V or carbide.

Blade Material vs. Cost
When premium steel pays back — and when D2 is the right answer.
Keep Every Granulator Running at Peak Output
Knife clearance — weekly
Rotor-to-bed knife gap should stay within 0.15–0.30 mm. A gap above 0.5 mm wastes 15–25% of
motor energy and tears plastic instead of cutting.
Inspeção de tela
Replace bent or worn screens — holes elongated beyond 110% let oversize regrind through. See
how screen size affects quality.
Resharpen, don’t replace
Tool-steel blades can be reground 6–10 times. An automatic grinder pays for itself within one blade set.
Bearing & belt schedule

Plastic Granulator — Frequently Asked Questions
Quanto custa um granulador de plástico?
A beside-the-press PC400 starts around US$4,000–6,000. Mid-range PC500 to PC600 run
US$8,000–18,000. Heavy-duty PC800 and larger range US$20,000–45,000 depending on blade
steel, screen quantity, and options (wet, stainless, PLC). See our
price factors breakdown.
Qual é a principal diferença entre um triturador primário e um granulador?
Shredders run at 20–120 rpm with very high torque and tear items up to 2 m into 20–100 mm
strips. Granulators run at 400–800 rpm and cut those strips — or smaller scrap — into
uniform 4–18 mm regrind through a screen. Most recycling plants use both in sequence.
Granulador úmido ou seco — qual eu preciso?
Wet granulators spray water through the cutting chamber to wash labels, dirt, and sand off
the regrind in one step — essential for post-consumer PET bottles and agricultural film.
Dry granulators are simpler, cheaper, and sufficient for clean in-house scrap (runners,
purging, industrial offcuts).
Qual tamanho de tela devo usar?
6–10 mm for direct extrusion, 8–14 mm for pellet lines, 10–18 mm for resale flake. Smaller
screens produce finer regrind but reduce throughput 20–40% and increase blade wear. Full
breakdown in our guia de tamanho de peneira.
Que tipos de granuladores de plástico existem?
Beside-the-press granulators (for injection molding scrap), central granulators (medium-duty
for general recycling), heavy-duty rigid granulators (for thick-wall and large items), wet
granulators (for washed material), vertical granulators (for pipes and profiles), PET
bottle granulators, and integrated shredder-granulator machines. Each type is optimized
for specific material sizes and throughput requirements.
Qual material de lâmina dura mais tempo?
For clean plastic, SKD-11 and DC53 deliver 1.3–1.8× the edge life of D2. For glass-filled or
fiber-reinforced feed, CPM-10V lasts 2–3× longer. For abrasive or metal-contaminated feed,
tungsten-carbide-tipped blades are the only practical option.
Quanta potência uma extrusora de plástico consome?
Typical specific energy is 0.05–0.12 kWh per kg of plastic, depending on material hardness
and regrind size. A PC600 rated 30 kW draws 15–25 kW under normal load. Dull blades can
push that to 0.15+ kWh/kg.
Com que frequência precisam ser afiadas as lâminas do granulador?
For clean PP/PE: every 150–300 operating hours. For PET bottles with labels: every 80–150
hours. For fiber-reinforced composites: every 40–80 hours. A single blade set typically
delivers 6–10 sharpening cycles before replacement.
Você pode projetar uma linha completa desde o trituração até a pelotização?
Yes. We engineer full recycling lines around feedstock, contamination level, target output,
and plant layout. Granulator selection is matched to required flake size and downstream
process — washing, drying, or pelletizing.
