Application

The Injection Low-Speed Series Plastic Scrap Grinder is one of the core pieces of equipment in our Beside-the--Press Series. Designed specifically for processors who have small injection moulding machines, this compact and energy-saving grinder helps save floor space and produce high-quality regrind from blow moulding machine runners and other small components. The grinder is designed with some features like tangential feed, case-hardened cutting chambers, low-speed motors, and staggered rotors with replaceable cassette knives that make it work efficiently. The staggered rotor design enables a higher number of cuts per revolution, thus improving the throughput and minimising the chances of jamming or shearing, while the scissor cutting action of the slanted rotor knives ensures better quality regrind. Experience the difference with our Injection Low-Speed Series Plastic Scrap Grinder and discover the new benchmark in quality and productivity.

Description

Low Speed Cutting System
  • Direct Driven Staggered Rotor: The rotor is directly connected to the motor, eliminating belt slippage and energy loss. The staggered blade layout increases cutting surface area and reduces load peaks for stable, efficient cutting.
  • Slow Rotor Speed Creates Less Noise and Dust: Operating at low RPM (approx. 200 RPM), the system avoids friction heating and minimizes dust, fines, and polymer degradation—ideal for high-quality material recovery.
  • Easy Access for Maintenance and Cleaning: The machine is designed with large access doors and tool-free maintenance points, reducing downtime, simplifying cleaning, and enabling faster blade changes.
  • Sliding Screen Cradle: The movable screen cradle allows smooth sliding for inspection or replacement, ensuring consistent granulate size and easy maintenance without dismantling major components.
  • Tilt Back Hopper: The hopper can be tilted backward for quick access to the rotor and cutter chamber, simplifying cleaning and reducing downtime between material changes.
  • 200 RPM Rotor: Low-speed rotor operation ensures high torque, quiet performance, reduced wear, and accurate granulation without overheating or material damage.
  • Safety Interlock: Built-in safety switches automatically stop the machine if the hopper or doors are opened, ensuring operator protection during cleaning and blade maintenance.
  • Caster Mounted: Heavy-duty castor wheels enable easy mobility, allowing operators to move the unit between different molding machines for flexible in-line recycling.

The Low Speed Cutting System utilizes a direct-driven, staggered rotor configuration that maximizes blade contact for smoother cutting and faster material reduction. Operating at slow, controlled speeds, the system significantly reduces noise, vibration, and dust formation—delivering superior cutting performance compared to traditional high-speed granulators. This gentle cutting action maintains polymer integrity and produces clean, uniform granules that enhance downstream processing efficiency. Designed for modern injection molding lines, the system features operator-friendly access points, quick cleaning capabilities, and safety-enhanced controls for reliable and long-term industrial performance.
