Solve Your Recycling Challenges

Handles Wet Material

Stop worrying about moisture. The integrated compactor and efficient venting system can process washed films with 3-5% moisture content without foaming or degradation.

20% compared to traditional multi-stage systems.

Non-Stop Operation

Equipped with a hydraulic screen changer, you can swap filters without stopping the machine, minimizing downtime and keeping your production line moving 24/7.

CE Certified
ISO9001 Quality
1-Year Warranty

Ideal Applications

Designed specifically for soft plastics, the ML Series turns these common waste streams into high-value granules.

Post-Industrial Film

Perfect for clean factory scraps, edge trims, and off-cuts of LDPE, LLDPE, and HDPE stretch films.

Washed Agricultural Film

Handles greenhouse films and mulch films that have been washed and squeezed, tolerating residual moisture.

PP Woven Bags

Efficiently densifies and pelletizes crushed raffia bags, cement bags, and jumbo bags (FIBCs).

Crushed Regrinds

Also suitable for pre-crushed rigid plastics like HDPE bottles, crates, and pipe flakes mixed with films.

Our 4-Step Process

1

Feeding & Compacting

Material is fed via conveyor into the compactor, where it’s cut, mixed, and densified for stable feeding.

2

Extrusion & Degassing

The densified material is forced into the single-screw extruder, then melted, plasticized, and vacuum degassed.

3

Filtration & Pelletizing

Molten plastic is filtered for impurities and then cut into uniform pellets by a water-ring pelletizing system.

4

Drying & Collection

Pellets are rapidly dewatered and sent to a silo for cooling, bagging, and storage.

Frequently Asked Questions

What is the maximum moisture content for materials?
This machine’s compactor unit is robust and can handle materials with up to 5% moisture. However, for the absolute best performance and highest pellet quality, we recommend feeding materials with a moisture content below 3%.
Can this model process heavily printed or colored films?
Absolutely. The single-screw design, combined with an effective vacuum degassing zone, is highly efficient at removing inks and volatiles. This ensures clean, high-quality pellets even from heavily printed source materials.
What is the typical maintenance for the screw and blades?
We recommend a daily check and cleaning of the pelletizing head. The cutting blades are made of high-strength alloy steel but should be checked for sharpness weekly; they can be easily sharpened or replaced. The main screw and barrel are engineered for a long service life, typically over 8000 operating hours before requiring major service.
How does this machine compare to a twin-screw model?
A single-screw system, like our ML Series, is the ideal choice for recycling a single type of polymer (like PE or PP film). It is highly efficient, durable, and more cost-effective. A twin-screw extruder is generally better for compounding different types of plastics or adding fillers, which is a different application.
What is your warranty and after-sales support policy?
The ML Series comes with a comprehensive 1-year limited warranty on major non-wear components. We offer comprehensive after-sales support including spare parts, remote technical assistance, and on-site service options. For full details, please visit our comprehensive FAQ & Support Center.
