Hey everyone, welcome! In this video, we’ll walk you through our full plastic recycling line—super easy to follow. Let’s dive right in!
Part 1: Shredding Line
Sequence: Rubber Belt Conveyor → Single-Shaft Shredder → PVC Belt Conveyor → Trommel
First up: the shredding line. It all starts with the rubber belt conveyor, which feeds the plastic waste smoothly into the star of the show—the DSJ 2000 single-shaft shredder with a moveable hopper. This shredder handles PP and PE film, bags—whatever soft plastics you’ve got—at up to 2 tons per hour. The moveable hopper helps prevent jams, and the large rotor boosts shredding efficiency.
After shredding, the material moves via the PVC belt conveyor straight into the trommel screen, where oversized pieces are filtered out. It’s a clean and continuous flow that keeps the line running smoothly.
Part 2: Washing & Squeezing Line
Sequence: Screw Conveyor → First Floating Tank → Centrifugal Dryer → Screw Conveyor → Second Floating Tank →Screw Conveyors →Squeezers → Silos
Now, let’s move on to the washing and squeezing line.
First, a screw conveyor carries the shredded film into the first floating tank, where dirt, sand, and light contaminants are separated quickly.
Next, the cleaned film goes into a centrifugal dryer, which spins off the excess water and gets the material semi-dry.
From there, another screw conveyor takes the material into the second floating tank for another round of washing—just to make sure it’s as clean as possible.
After that, two screw conveyors move the plastic to two JGJ 320 squeezers. These densifier units use screw-pressing action to remove even more moisture, compressing the film into dense, semi-dry chunks. The final moisture is around 3%, and the density goes up to 300 kg/m³—perfect for storage or direct feeding into a pelletizing line.
Finally, everything drops into the hopper, ready for the next step.
And that’s our full line—shredding, washing, squeezing—done in under four minutes. Short, clear, and effective. Thanks for watching!

Frequently Asked Questions
What materials can this film washing line process?
The line handles PP and PE film, plastic bags, and other soft plastic waste at up to 2 tons per hour through the shredding stage. The DSJ 2000 single-shaft shredder with a moveable hopper is built for light, flexible materials that tangle in ordinary equipment. Both post-industrial and post-consumer film streams work well, with the washing stages adjusted to match contamination levels.
What moisture and density does the finished material reach?
After the two JGJ 320 squeezers, final moisture is around 3% and bulk density reaches up to 300 kg/m³. The screw-pressing action both dewaters and densifies the film into compact, semi-dry chunks. This combination of low moisture and high density makes the material economical to store and ideal for direct feeding into a pelletizing extruder without bridging or surging.
How does the washing sequence work?
Shredded film travels by screw conveyor into a first floating tank that separates dirt, sand, and light contaminants, then through a centrifugal dryer that spins off excess water, then into a second floating tank for a final wash. Two screw conveyors feed the twin squeezers for dewatering and densifying. This multi-stage sequence delivers clean film with consistent, low moisture.
What happens after the washing line — where does the material go?
Densified, semi-dry film drops into a hopper ready for the next step: typically a pelletizing line where an extruder melts, filters, and pelletizes it into recycled granules. Because the squeezers already densified the material to 300 kg/m³, extruder feeding is stable and efficient. See our pelletizing line selection guide to match the right extrusion setup to your material.
What utilities and space does the line need?
Plan for three-phase industrial power sized to the full equipment train (shredder, conveyors, dryer, squeezers, and controls), plus process water supply and drainage for the two floating tanks. The line layout — rubber belt conveyor, shredder, trommel, washing tanks, and squeezers — needs a long, clear floor run with access for maintenance. Exact power, water, and footprint figures are provided with the quotation for your configuration.
How does the moveable hopper prevent jams?
Film is notorious for bridging and wrapping, which starves or jams fixed hoppers. The DSJ 2000’s moveable hopper agitates the feed zone to keep light film flowing into the large rotor, while the trommel screen downstream filters out oversized pieces. Together with steady conveyor feeding, this keeps the line running continuously instead of stopping for manual clearing — a key advantage for soft-plastic processing.
