⚙️ Machine Overview
Model: TR 120 49 / TR NS (Tria TR Series) — specifically designed for shredding full sheet thermoformed material (e.g. PP, PS, PET) inline on thermoforming lines or as a standalone granulator with rear trap door feed.
Equipped with a sound proof cabin, it includes a water cooled cutting chamber and tungsten tipped knives for enhanced wear resistance.

🔧Design Features & Benefits
• High throughput: Large rotor diameter and wide infeed enable processing up to ~1.2 tons/hour of thermoformed scrap.
• Efficient cutting: The 50% screen area relative to rotor circle allows rapid discharge, minimizing dwell time and fines.
• Robust wear protection: Tungsten tipped blades and hardened chamber surfaces extend service intervals.
• Precision gap control: Pre-set blades with gauge ensure consistent knife-to-screen clearance, easing maintenance.
• Inline compatibility: Rear trap-door feed is ideal for inline thermoforming integration; designed to synchronize with extruded/reel-fed lines.
• Operator safety & comfort: Sound-insulated housing and cooled chamber reduce noise exposure and dust.
