Plastic Fiber Shredder: Specialized Equipment for High-Efficiency Processing of Plastic Fiber Waste

In the field of plastic fiber recycling, the plastic fiber shredder is a specialized piece of equipment that solves the problems of plastic fibers being easily tangled and difficult to break. It can process various types of plastic fiber waste, including waste plastic fiber yarn, fiber cloth, fiber rope, and fiber fillers, such as polyester, nylon, polypropylene, and acrylic fibers. It can shred fine, fluffy plastic fibers into uniform fragments of 5-20mm, providing high-quality pre-treated materials for subsequent opening, melt granulation, and other recycling processes, significantly improving the recycling rate of plastic fiber waste.

The core structure of the equipment is designed around "anti-tangling + high-efficiency shredding," including an anti-drift feeding system, a dedicated shredding system, and a smooth discharge system. The feeding system employs a sealed feeding hopper, paired with a spiral pusher with a comb-like structure. The comb effectively combs and clumps the plastic fibers, preventing them from scattering or agglomerating during feeding, while simultaneously and stably pushing the material into the shredding chamber. The core of the shredding system is a single-shaft cutter roller, equipped with serrated high-strength alloy blades. The blade spacing is precisely controlled between 3-8mm, enabling rapid cutting of long-chain plastic fibers. A rotating anti-winding scraper is added to the side of the cutter roller to clean fibers entangled on the cutter shaft in real time, preventing equipment jamming. The discharge system uses a conveyor belt with negative pressure adsorption. The negative pressure adsorbs fine fiber fragments, preventing them from scattering and ensuring smooth discharge. During operation, plastic fibers enter through the feeding hopper, are combed and pushed into the shredding chamber by the pusher, and the high-speed rotating single-shaft cutter roller shears the fibers. The anti-winding scraper simultaneously cleans the cutter shaft, and the final fragments are conveyed out via the negative pressure conveyor belt, completing the shredding process.

Compared to ordinary shredding equipment, plastic fiber shredders have three core advantages: First, they offer superior anti-tangling performance. The serrated blades and scrapers work together to completely solve the problem of plastic fibers entangled in the blade shaft, achieving a continuous operating rate of over 96%. Second, they offer high shredding efficiency. Optimized blade roller speed and shearing force based on fiber characteristics allow for a processing capacity of 150-600 kg per hour, 55% higher than general shredders. Third, they are highly adaptable, capable of processing monofilament fibers, multifilament fibers, and mixed waste materials with small amounts of fabric, eliminating the need for pre-sorting and reducing labor costs.

Operation and maintenance precautions: Before starting the machine, check the blade clearance and adjust it to the appropriate spacing based on fiber thickness. When processing high-bulk fibers, control the feed rate to avoid overloading the equipment. In daily maintenance, clean residual fibers from the feed hopper and shredding chamber weekly, check blade wear monthly, and add high-temperature grease to the bearings quarterly to ensure stable operation. Currently, this equipment is widely used in plastic fiber production plants and waste textile recycling companies, providing key equipment support for the recycling of plastic fibers.
