Definition
What is a plastic recycling granulator?
A recycling granulator feeds scrap film into a cutter, melts and filters the polymer in an extruder, then strands or cuts it into uniform pellets. With washing and drying stages, even contaminated edge trim becomes usable regrind.
E-SHION's SJ series processes HDPE, LDPE and PP scrap at 150–1000 kg/h with screw diameters from 100 to 150 mm — sized for closed-loop recycling next to a blown film line.
Applications
What it is
used for
Closed-loop film recycling
Edge trim and scrap back into the same blown film line.
Post-industrial scrap
Purge, start-up waste and off-spec film converted into salable pellets.
Washing lines
Dirty film and agricultural scrap washed, dried and pelletized.
Material upgrading
Consistent pellets with controlled melt flow for bag and film producers.

Match the granulator to your scrap volume
Which granulator for which volume?
Real SJ-series outputs — size the machine to your daily scrap, not to a brochure.
| Model | Screw diameter | Output | Main motor | Best for |
|---|---|---|---|---|
| SJ100 | Φ100/100 | 150–200 kg/h | 30 kW | Small film lines and edge trim |
| SJ120 | Φ120/120 | 200–250 kg/h | 55 kW | Medium bag plants |
| SJ140 | Φ140/140 | 300–350 kg/h | 75 kW | High-output film lines |
| SJ150 | Φ150/150 | 450–500 kg/h | 90 kW | Largest single-line scrap volumes |
Larger granulating systems up to 1,000 kg/h are configured on request.

Frequently asked
questions
What can it recycle?
Film scrap, edge trim, purge and off-spec rolls of PE and PP. With a washing stage, contaminated agricultural and post-industrial film can also be processed.
Can pellets go back into my blown film line?
Yes — that is the closed-loop configuration: the granulator sits beside the film line and feeds regrind at a controlled ratio.
What output do I need?
From 150 to 500 kg/h depending on screw size; choose by your daily scrap volume and the output of your film line.
How does the line work?
Shred or cut → wash (optional) → extrude and filter → strand or cut into pellets → cool and pack.
Is it CE certified?
Yes — all E-SHION machinery is assessed to the Machinery, Low Voltage and EMC directives.
