Application Areas

These granulators are versatile for production and recycling. By internal grinding, you reduce waste and logistics costs, improve OEE, and increase the value of by-products.

Injection Molding Sprues and Production Waste

Grind waste streams directly back into the line. Less virgin material needed and a quick ROI.

Pipes, Profiles, and Sheets (PVC/PE/PP)

Grind snip remnants and pipe ends. The ground material is ideal for regranulation or direct reuse.

Thick/Rigid Parts and Blocks

Layer-by-layer cutting produces homogeneous ground material (12–40 mm) with high output.

Cardboard, pallets, and containers

Significant volume reduction and lower logistics costs. Robust machine for continuous operation.

Electronic enclosures (ABS/PC/PS)

Fine and clean feedstock for closed-loop applications and higher yield.

Shredder output and pre-crushed lumps

Second step after shredding for higher line capacity and uniform product.

Key Features

Easy Maintenance

Access to the cutting chamber and filter screen within seconds – faster cleaning, less downtime.

Adjustable Knives

Adjustable knives ensure precise cutting and easy resharpening when needed.

Sound Damping

Integrated sound insulation makes indoor use comfortable and safe for personnel.

How Does It Work?

Our granulators are designed for shredding hard plastics down to 2 cm thick. Thanks to the stepped system of the blades and the wide rotor, the material is cut layer by layer until it is small enough to pass through the sieve.

Standard models reach up to 300 kg/hour. For larger volumes, we offer XL models up to 1200 kg/hour.

Frequently Asked Questions

What is the capacity per model?
Typical output ranges from approximately 300 kg/hour (standard models) to 1200 kg/hour (XL models). The actual capacity depends on material type, wall thickness, screen size, and the method of feeding.
How much noise does the machine produce?
With sound insulation, the noise level is usually around 70–85 dB(A), depending on the material. Additional encasing and vibration dampers are available for quieter operation.
Which sieve size should I choose?
For reuse in production: often 8–12 mm for thin-walled applications and 12–30 mm for general use. Coarser (40–60 mm) for volume reduction or as a pre-step for extrusion. We are happy to advise based on your goals.
How often should the blades be sharpened?
This depends heavily on the material and hours of operation. With adjustable and reversible blades, you can delay sharpening/replacement. In practice, this varies from every 2–6 weeks under a 1-shift schedule.
Can I integrate with a conveyor belt, blower, or metal detection?
Yes. Options include a conveyor belt with an infeed auger, cyclone/blower with bigbag or silo, and inline metal detection/magnets to minimize blade wear. Control can be linked.
What about energy consumption and safety?
Peak power is specified; actual consumption is often 40–70% depending on the load. Safety: CE-compliant, doors with safety switches and emergency stops are standard.
