Why Choose the RTM-2360-CRPS?

Turn a costly waste stream into a valuable asset with a machine specifically designed for the challenges of extruder purgings.

Maximum Material Reclamation

Stop discarding valuable polymer. Our shredder efficiently processes tough lumps, allowing you to reuse material and reduce costs.

High-Torque Performance

The specialized H-series reducer delivers immense torque at low speeds, effortlessly shearing through dense, solid plastic waste.

Cost-Efficient Operation

4-sided, rotatable blades quadruple the lifespan of each knife, dramatically reducing maintenance costs and downtime.

Automated & Safe Processing

The intelligent PLC system with a hydraulic ram provides hands-free operation and automatic overload protection for superior safety.

Engineered for Unmatched Durability

From its core construction to its control system, every component is selected for performance and longevity in demanding industrial settings.

  • Solid, Weld-Free Rotor Shaft
    CNC-machined from a single block of tempered 45-grade steel for maximum strength and resistance to shock loads.
  • 4-Sided, Rotatable SKD-11 Blades
    Made from high-strength alloy steel, each blade can be rotated three times to present a new cutting edge, maximizing lifespan.
  • Powerful Hydraulic Ram Pusher
    Automatically and intelligently feeds material into the cutting rotor with consistent pressure for efficient, continuous shredding.
  • Intelligent PLC Control System
    Features automatic overload protection and forward/reverse functions to clear jams and ensure smooth, uninterrupted operation.
  • External Bearing Seats
    Bearings are mounted outside the cutting chamber, protecting them from contamination and making them easy to access and service.
  • High-Torque Gearbox Drive
    The direct-drive H-series reducer with a built-in shock absorber delivers power efficiently and protects the drivetrain.

Frequently Asked Questions

What exactly is “extruder head waste”?

Extruder head waste (also known as purgings, die-drool, or lumps) is the dense, solidified plastic that is purged from an extrusion machine during color/material changes or shutdowns. It is often very tough and difficult to process with standard granulators, making a specialized high-torque shredder like the RTM PurgeShred the ideal solution.

How do the 4-sided knives work and why are they better?

Each individual cutting blade on the rotor has four identical cutting edges. When one edge becomes dull from use, your maintenance team can simply unbolt the blade, rotate it 90 degrees to a fresh, sharp edge, and re-bolt it. This means you get four times the operational life out of a single set of blades, drastically reducing maintenance costs and machine downtime compared to single-edge knives.

Can this machine be used for other types of plastic waste?

Absolutely. While the RTM-2360-CRPS is specifically optimized for tough, dense materials like extruder waste, its robust design and high-torque motor make it highly effective for shredding a wide range of other materials, including thick-walled pipes, plastic drums, and baled films.
