Blade-type crushing and pulverizing production line
The Mao Yue Blade-Type Shredding-Grinding Production Line is a specialized integrated recycling solution designed for efficient processing of medium-hardness,high-impact plastic waste. Centered around a heavy-duty blade crusher as the primary front-end equipment, this line integrates a precision disc mill (available in 500/600/800 models), negative pressure pneumatic conveying, cyclone separation, vibrating screening, and a pulse-jet baghouse dust collection system. It achieves fully automated continuous processing from large plastic waste pieces (such as pipes, profiles, sheets, barrels, pallets, woven bags, etc.) into uniform fine powder (20–80 mesh or finer).
It is particularly suited for high-value recycling and regeneration of materials like PVC, PE, PP, PET, ABS, and EVA. The Mao Yue Blade-Type Crushing-Grinding Production Line excels in precision and efficiency. Its front-end employs a heavy-duty multi-blade high-speed cutting structure. The blades' rapid rotation generates continuous, powerful shearing and cutting forces, specifically optimized for medium-hardness, brittle materials. It rapidly processes waste injection-molded parts, bottles, film clumps, electrical casings, and rigid panels into uniform small pieces. It delivers high cutting efficiency and excellent particle size consistency, completely avoiding the common issues of dust dispersion, over-grinding, material entanglement, blade jamming, and machine shutdowns associated with hammer-type crushers. It offers broad adaptability and extended maintenance intervals. Coarsely crushed material seamlessly interfaces with Mao Yue disc mills (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 an extremely narrow fine particle size distribution, exceptional uniformity, no agglomeration, and excessive fine powder. This makes it ideal for downstream applications demanding high dispersion, flowability, and surface finish, such as color masterbatches, functional masterbatches, modified plastics, rotomolding powders, and SPC flooring core powders. 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 resolves issues such as overheating, blade adhesion, yellowing, and degradation during high-speed cutting and grinding of heat-sensitive materials like PVC, PET, and ABS, ensuring complete powder properties and excellent flowability. The coarse crushing section offers optional air cooling or localized water cooling for the blade area, further controlling temperatures and extending blade lifespan. Fully enclosed negative-pressure pneumatic conveying integrated with high-efficiency pulse bag dust collection spans the entire line, achieving zero dust leakage and a capture rate exceeding 99.9%. This fully complies with national environmental emission standards, ensuring dust-free workshops, safe production, and comprehensive employee health protection. It also minimizes fine powder loss, enhances raw material utilization, and increases recycling value. The modular integrated system offers flexible footprints and high automation, ensuring stable operation and easy maintenance. Compared to traditional hammer milling + separation grinding systems, blade cutting delivers greater precision, lower dust emissions, reduced energy consumption, and extended tool life, resulting in a shorter investment payback period.
The Mao Yue Blade-Type Crushing-Grinding Production Line is suitable for efficient recycling and regeneration of various waste plastics, providing a one-stop precision cutting solution from scrap materials to high-quality fine powder. In injection molding and blow molding waste recycling, it rapidly crushes scrap injection molded parts, bottles, film clumps, appliance casings, toy scraps, etc., directly grinding them into highly dispersed fine powder. This powder can be reused in injection molding regeneration, modified material production, or masterbatch remanufacturing, significantly reducing raw material procurement costs. For PET bottle flakes and sheet recycling, it efficiently processes brittle materials like waste PET bottles, sheets, and packaging straps. After crushing, these are finely ground into powder for use in regenerated PET sheets, fibers, injection-molded products, and other applications, enabling high-value circular utilization.
For ABS/PS engineering plastic recycling, it crushes waste ABS/PS materials like appliance casings, keyboards, monitor housings, and toys into uniform fine powder. This powder is reused in injection molding, modification, and composite material production, enhancing the mechanical properties and stability of recycled materials. Simultaneously suitable for processing PVC film and mixed rigid/flexible materials, including waste PVC film, mixed rigid/flexible compounds, and flooring offcuts. After crushing and cutting, these are ground into fine powder for reuse in pipe extrusion, flooring substrates, and profile regeneration processes, advancing the PVC circular economy. Furthermore, this production line is particularly suited for masterbatch and functional masterbatch pre-treatment and recycling. It coarsely crushes masterbatch scraps and injection molding waste before finely grinding them into high-quality powder. This powder can be used for masterbatch remanufacturing, functional masterbatch production, or directly supplied to downstream modified material plants, improving pigment dispersion and product quality. Whether processing injection molding waste, bottle flakes, engineering plastics, or mixed rigid/flexible materials, the Mao Yue blade-type crushing-grinding production line meets diverse plastic recycling demands through precise cutting, efficient fine grinding, low costs, and high recovery value. This achieves maximum resource utilization and environmental compliance.
This model features a disc diameter of approximately 470-500mm, a main motor power of 37-45kW, a typical production capacity of 100-300kg/h, and a spindle speed of 3600-3800rpm. Equipped with 24-28 replaceable moving blades + high-density fixed tooth plates, it delivers high shearing efficiency and wear control for PVC with medium to low filler content, with a service life of approximately 500-800 hours. Intelligent temperature control + water-cooled circulation maintains grinding chamber temperature at 45-55°C, preventing PVC decomposition/yellowing.
