Eurotech T-100 Plastic Pelletizer for Extrusion Lines

Overview

The Eurotech T-100 Plastic Pelletizer is an industrial-grade strand pelletizing system engineered for integration into continuous extrusion lines serving the rubber and plastic compounding industry. It operates on the principle of controlled strand cooling, precise cutting, and rapid dewatering to convert molten polymer extrudates into uniform, free-flowing cylindrical pellets. Unlike underwater or air-cooled pelletizers, the T-100 employs a water-bath quenching zone followed by a rotating knife assembly mounted on a rigid, dynamically balanced shaft — ensuring dimensional consistency, minimal dust generation, and high geometric integrity across batch-to-batch production. Its design prioritizes mechanical stability under sustained thermal and mechanical load, making it suitable for both virgin polymer processing and post-consumer recyclate regranulation where melt homogeneity and particle density are critical to downstream handling and injection molding performance.

Key Features

• High-torque, low-noise gearbox with hardened helical gears and precision-ground bearings — delivers consistent rotational speed (±0.3% regulation) across 50–600 rpm operating range
• Screw and barrel fabricated from nitrided alloy steel (HV ≥ 950) or bimetallic-lined variants (e.g., X40CrMoV5-1 + tungsten carbide overlay), providing >10,000 hours of wear resistance in abrasive filler-loaded compounds
• Modular exhaust configuration: selectable vacuum vent (−0.08 MPa absolute) or atmospheric vent port — enables effective removal of volatiles, moisture, and residual monomers during pelletization
• Adjustable strand guide geometry and water-bath immersion depth — accommodates strand diameters from 1.8 mm to 4.5 mm with ±0.05 mm tolerance control
• Knife carrier assembly with hydraulic preloading and tool-free blade change mechanism — supports quick interchange of hardened HSS or carbide-tipped blades (ISO 513 Class K20)
• Integrated pellet drying tunnel with variable-frequency blower and stainless-steel mesh conveyor — achieves residual moisture <0.05 wt% for hygroscopic resins including PA6, PC, and PET

Sample Compatibility & Compliance

The T-100 is validated for use with thermoplastic polymers exhibiting melt flow rates (MFR) from 0.5 to 40 g/10 min (ASTM D1238, 230 °C/2.16 kg). It supports both single-screw and twin-screw extrusion feedstocks, including filled systems (up to 40 wt% CaCO₃, talc, or glass fiber), flame-retardant formulations (halogen-free and brominated), and conductive compounds (carbon black or metal flake loaded). All wetted components comply with FDA 21 CFR §177.1520 for food-contact polymer processing. Electrical architecture conforms to IEC 60204-1; CE marking includes Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. Optional GMP-compliant documentation packages include FAT/SAT protocols and material traceability records per ISO 9001:2015.

Software & Data Management

While the T-100 operates as a stand-alone unit with analog/digital I/O interfaces, it is fully compatible with third-party SCADA and MES platforms via Modbus RTU (RS-485) and EtherNet/IP protocols. Standard HMI provides real-time monitoring of cutter motor current, water bath temperature (±0.5 °C), and pellet throughput (kg/h), with configurable alarm thresholds and event logging. Audit trails meet ALCOA+ principles when integrated with validated LIMS or electronic batch record systems. Optional Eurotech PelletIQ™ module adds predictive maintenance alerts based on vibration signature analysis (ISO 10816-3 Class A) and historical wear trend modeling.

Applications

• Recycled polyolefin regranulation: sorting, washing, extrusion, and pelletizing of post-industrial and post-consumer PP/PE waste streams
• Color masterbatch production: high-shear dispersion of organic pigments and inorganic oxides into carrier resins with narrow particle size distribution (PSD D90 < 1.2 mm)
• Engineering thermoplastic compounding: pelletization of reinforced PA66, flame-retarded PC/ABS blends, and thermally conductive POM composites
• Medical-grade polymer processing: compliant pellet production for ISO 10993-15 extractables testing and USP resin qualification
• Biopolymer processing: low-thermal-degradation pelletizing of PLA, PHA, and starch-based blends requiring precise residence time control

FAQ

What extruder output rates is the T-100 rated for?
The T-100 supports nominal extrusion outputs from 100 to 1,200 kg/h, depending on polymer viscosity, strand count (12–36 strands), and pellet diameter specification.
Can the T-100 handle highly filled compounds containing >30% mineral fillers?
Yes — its hardened screw/barrel system and reinforced knife drive train are specifically qualified for calcium carbonate-, talc-, and wollastonite-filled systems up to 40 wt%, with documented service life exceeding 8,000 operational hours.
Is vacuum venting mandatory for all applications?
No — vacuum venting is recommended for hygroscopic resins (e.g., PA, PET), volatile additives (plasticizers, lubricants), or recycled feedstocks with residual moisture; atmospheric venting suffices for stable polyolefins and PS.
Does Eurotech provide validation support for pharmaceutical or medical device manufacturing?
Yes — optional IQ/OQ documentation, 3Q protocol templates, and calibration certificates traceable to NIST standards are available upon request for regulated environments.
