Plastic regranulation line PURUI ML 100 integrated with densifier

Hello.

We offer a professional, high-performance plastic recycling line for LDPE, HDPE and PP. The machine is in excellent technical condition, after key service works, and ready for immediate production start-up.

Year of manufacture: 11/2019.

Equipment description:
The offered production line by PURUI Plastics & Rubber Machinery is designed for recycling plastic waste: LDPE, LLDPE, HDPE and PP.
The machine is ideally suited for processing film (loose, baled, printed), bags, as well as rigid regrind.
Thanks to the integrated densifier, the process is carried out in a single stage, without the need for preliminary material agglomeration.

New plasticizing unit:
The screw and barrel were replaced with brand-new components in January of this year.

Documentation:

The machine has full DTR documentation and a CE certificate of conformity, allowing safe operation and compliance with health, safety and environmental requirements.

Filtration system:
The machine is equipped with a professional, dual-piston, four-position (4-screen) hydraulic screen changer of the Non-stop type.
Filtration area: 4 screen positions for screens with a diameter of Ø250 mm each.
The system enables sequential screen replacement without interrupting production and without pressure surges, ensuring process continuity and good granulate quality.

Technical parameters:
Screw: Ø100 mm. L/D ratio: 36:1 (ensures good homogenization and efficient vacuum degassing).
Output: 250 - 350 kg/h (depending on the type of raw material).
Main drive power: 145 kW (main extruder motor 90 kW + densifier motor 55 kW).
Total installed power: approx. 200 - 220 kW (includes drives, heating zones and auxiliary systems).
Screw speed: up to 120 rpm.

Line design and equipment:
Integrated densifier automatically shreds, dries and preheats the material, feeding it directly into the extruder under constant pressure.
Belt conveyor: feed conveyor with metal detector.
High-torque gearbox: gearbox with oil cooling system, designed for continuous 24/7 operation in demanding recycling conditions.
Degassing system: single vacuum degassing removing moisture and gases generated from printing inks.
Automation: intuitive touch control panel with precise temperature control in each heating zone.
The installed frequency inverters enable smooth start-up and speed control, significantly extending the service life of the gearbox and motors while reducing sudden power consumption spikes.
Cutting system: water-ring cutting at the die head. Automatic adjustment of knife pressure against the die head.

Condition: well-maintained machine, after inspection, with a new plasticizing unit.

Inspection option: we invite you to inspect the machine and see it running during tests.
