Commercial PET Bottle Crusher for Sale: High-Capacity Plastic Recycling Equipment

24/05/2026

Struggling with PVC, paper, or cross-polymer contamination in your plastic flakes? The Rumtoo Sink-Float Separation Tank delivers 98%–99% pure density separation for PET, PE, and PP flakes, scaling from 800 to 5,000 kg/h.

How it protects your profit margins:

99.5%+ Purity for Premium Pricing: Twin-tank design with precise brine adjustment meets food-grade rPET standards, separating HDPE caps and PP rings from PET flakes.

85% Water Savings: Integrated Dissolved-Air Flotation (DAF) loop slashes make-up water consumption from 20 m³ to just 3–5 m³ per ton.

3× Longer Filter Lifespan: Removes paper, film, and PVC before extrusion, preventing melt-filter clogging and reducing costly screen-replacement downtime.

Anti-Tangle & Anti-Floating Engineering: Specialized paddle blades resist film roping, while built-in de-foaming baffles force thin PET flakes to sink reliably.

Stop losing premium pellet yields to contamination. Contact our technical team for a custom 3D line layout and ROI evaluation.

Turn tricky mixed plastics into clean, single-polymer streams with Rumtoo’s plastic electrostatic separator. Our dry PVC/PET/ABS purification machine uses high-voltage electrostatic separation to remove PVC, PS and other contaminants from PET, PE/PP and more – even black and mixed-color flakes.

By targeting surface charge instead of color, it goes beyond traditional NIR sorting and sink-float, helping you hit low-ppm targets and unlock higher-value rPET and recycled resins. Whether you run PET bottle lines, mixed rigid plastics, WEEE plastics or cable recycling, the separator integrates after washing and drying as a final polishing step to boost purity and ROI.

Labels still showing up in your "clean" flakes?

After washing and drying, most recycling lines still carry lightweight contaminants — paper label fragments, thin film scraps, dust, and fines. These slip past screens and float-sink tanks, then cause pressure swings at the extruder and black specks in your pellets.

A zig-zag air classifier fixes this in one compact step. Rising air inside a multi-stage angular column lifts the light stuff out while heavy flakes fall through clean.

Here's what makes the zig-zag design different from a basic air separator:

— Multiple separation stages, not just one pass
— Adjustable airflow to fine-tune the cut point for your specific material
— Vertical column = small footprint on the factory floor

We just published a full guide covering:
- Where exactly to place it in your line (hint: after drying, always)
- How to size the channel width and blower for your throughput
- The 4 most common mistakes that kill separation performance
- Zig-zag vs. air tables vs. ballistic separators — when to use what
