Inline Haul-off Crusher

The Inline Haul-off Crusher is an advanced recycling system designed to achieve efficient and fully automatic edge trim and film scrap recovery during extrusion processes. It integrates traction, crushing, and conveying into a seamless in-line system, ensuring the material remains clean, dry, and directly reusable. This equipment is essential for film extrusion, sheet extrusion, and coating production lines, supporting materials such as PET, PP, PS, PE, PLA, and biodegradable resins.
It represents a modern solution for achieving sustainable production and optimizing resource utilization in the plastics industry.

Introduction to The Inline Haul-off Crusher

The Inline Haul-off Crusher combines a precision traction unit, high-efficiency crusher, and air conveying system into one compact structure. During extrusion, film edge trims or sheet scraps are continuously hauled, compacted, and fed into the crushing chamber. The material is immediately crushed into uniform flakes and pneumatically conveyed back to the extruder feed inlet, where it mixes with virgin material for re-extrusion.
This process ensures 100% in-line recycling, reducing material waste and labor costs while maintaining material integrity. The clean, closed-loop design prevents oxidation, dust contamination, and moisture absorption, preserving the product’s mechanical strength, surface gloss, and uniform color. It’s an ideal choice for manufacturers seeking high-efficiency, low-carbon, and intelligent recycling solutions.

Benefits of The Inline Haul-off Crusher

1. 100% In-line Recycling

Achieve immediate edge trim recovery, eliminate waste, and reduce raw material cost. The system operates synchronously with the extrusion line, ensuring that edge trims and scraps are recycled in real time without interrupting production. This continuous recycling loop not only minimizes material loss but also improves production efficiency and helps enterprises meet zero-waste manufacturing goals.

2. Quality Preservation

Prevents oxidation and moisture absorption, maintaining product color, gloss, and physical strength. Because the material is crushed and re-fed immediately after trimming, it remains clean, dry, and free from environmental contamination. This guarantees that recycled materials can be reused without compromising the visual or mechanical quality of finished products, achieving consistent production standards.

3. Energy Saving and Eco-friendly

Reduces material waste and energy consumption, contributing to sustainable production. The closed-loop system reduces the need for additional drying, cleaning, or manual recycling steps, thereby lowering overall power consumption. By improving raw material utilization and reducing carbon footprint, it helps manufacturers align with global environmental and energy-saving regulations.

4. Stable and Safe Operation

Equipped with overload, overheating, and noise protection systems to ensure reliable, low-noise performance. The fully enclosed structure with sound-absorbing insulation minimizes noise pollution and creates a safer, more comfortable working environment. At the same time, the integrated protection circuitry and intelligent monitoring ensure long-term stability even under high-load, 24-hour operation conditions.

5. Wide Material Compatibility

Suitable for PET, PP, PS, PE, PLA, and biodegradable materials across film, sheet, and coating production lines. It can handle both soft and rigid materials with equal precision, adapting to various extrusion and lamination processes. This flexibility makes it an ideal recycling solution for multi-material production facilities looking to improve efficiency and reduce cross-contamination.
