Hammer-impact swing-knife crushing and pulverizing production line

The Mao Yue hammer-blade crusher and grinding production line leverages integrated high-efficiency design as its core advantage. Its front-end heavy-duty hammer-blade coarse crushing structure employs high-speed rotating blades to generate powerful impact and shear forces, effortlessly breaking down large-sized pipes, profiles, sheets, foam boards, woven bags, pallets, and other waste materials. Its wide feed inlet (customizable) and uniformly adjustable particle size (5–20mm) completely eliminate the entanglement and jamming issues common in traditional knife-type crushers, offering high processing capacity and exceptional adaptability. Post-crushing material seamlessly interfaces with the Mao Yue disc mill (available in 500/600/800 models), equipped with DC53 high-grade mold steel grinding discs. Combining Taiwan-imported CNC tooth-by-tooth precision grinding with German dynamic balancing calibration, it achieves uniform fine powder output free of lumps with exceptional dispersion. This makes it perfectly suited for high-quality applications like rotomolding powder and SPC core layer powder. The grinding section features a standard reinforced dual cooling system. Combined with multi-point temperature sensors and PLC intelligent control, the grinding chamber temperature is precisely stabilized between 50–80°C.

This completely solves issues such as overheating, plate adhesion, yellowing, and degradation of heat-sensitive materials like PVC/PE, ensuring good powder flowability and no loss of performance. The coarse crushing section offers optional air cooling or water mist assistance, further adapting to different materials. Fully enclosed negative-pressure pneumatic conveying + high-efficiency pulse bag dust collection spans the entire line, achieving zero dust leakage and >99.9% capture efficiency. This fully complies with national environmental emission standards, ensuring dust-free workshops, safe production, and comprehensive employee health protection. It also prevents fine powder waste and improves raw material utilization. The line features modular integration, flexible footprint, and high automation (PLC centralized control, variable-frequency feeding, one-button start/stop), ensuring stable operation and simple maintenance. Compared to traditional separate crushing + grinding systems, it significantly reduces labor, space, and electricity costs, offering a short investment payback period.

The Mao Yue hammer-blade impact crusher and grinding production line is suitable for various plastic recycling and regeneration scenarios, providing a one-stop, high-efficiency solution for transforming large plastic waste into high-quality fine powder. In PVC pipe, profile, and sheet recycling: Effortlessly crush large scrap PVC pipes, window/door profiles, flooring sheets, foam boards, etc., directly grinding them into uniform fine powder. This powder can be reused in SPC flooring core layers, pipe extrusion, profile regeneration, and other applications, substantially reducing raw material procurement costs. For processing PE PP rotational molding and blow molding waste, it handles discarded PE PP items like barrels, pallets, trash bins, toys, playground equipment, and woven bags. It produces 30–80 mesh high-flow uniform powder suitable for new rotational molding products or modified material production, achieving true closed-loop recycling and resource circulation.

It is also suitable for engineering plastic recycling, such as PET, ABS, and EVA. crushing bottle flakes, appliance casings, films, foamed materials, and other items into fine powder for reuse in extrusion, injection molding, modification, and other fields, enabling high-value regeneration. Furthermore, this production line is particularly suited for centralized industrial plastic waste treatment centers, providing recycling stations, environmental enterprises, and plastic processing plants with large-scale waste plastic crushing-grinding turnkey solutions. It achieves resource utilization, significantly reduces costs and increases efficiency while fully complying with environmental regulations. Whether processing rigid or flexible materials, the Mao Yue hammer-blade pulverizing production line efficiently, stably, and cost-effectively meets diverse plastic recycling and regeneration demands.
