This blade is forged using high-density wear-resistant alloy steel (such as chromium-molybdenum-vanadium alloy or similar high-hardness materials, subjected to multiple precision heat treatments), achieving a hardness of HRC 60-65 or higher. This significantly exceeds the HRC 45 standard of ordinary cutting discs, ensuring exceptional impact and wear resistance. Even when processing glass-fiber reinforced or high-toughness plastics, wear rates are reduced by over 70%.
A single-blade set easily achieves 800 hours of continuous service life, significantly lowering replacement frequency and maintenance costs to deliver a “long-lasting, low-cost” operational experience.
The core advantage of Mao Yue PE grinding machine blades lies in their proprietary high-wear-resistant alloy steel material and specialized heat treatment process. This achieves exceptionally high cutting-edge hardness and outstanding impact resistance. Compared to standard market blades, service life is extended by 2-3 times or more, substantially reducing replacement frequency and significantly lowering downtime maintenance costs and labor losses. Additionally, the blades feature precision-adjustable clearance (supporting micron-level fine-tuning). Combined with Mao Yue's unique high-speed rotating tooth design, this achieves efficient shearing and friction grinding of PE materials. The finished powder fineness is stably controlled at 20-80 mesh or finer, with uniform particle distribution free of coarse particles or agglomerates. This ensures consistent downstream processing quality, making it particularly suitable for demanding applications like recycled pelletizing, film blowing, and injection molding. Furthermore, the multi-tiered finned heat dissipation structure with high thermal conductivity materials effectively controls disc temperature during grinding. This prevents overheating, softening, edge dulling, or deformation caused by friction heat in PE materials. Even under 24-hour industrial-scale continuous production, the blades maintain long-lasting sharpness and stable performance. As an original Mao Yue accessory, this blade perfectly fits mainstream disc diameters (e.g., 500mm/600mm/800mm) of PE/PP series pulverizers, offering strong compatibility and partial adaptability to other brands. It delivers premium quality at an affordable price, rivaling international top-tier brands, and supports customized disc diameter, tooth profile, and material specifications. More importantly, finer and more uniform powder output helps downstream extrusion/injection molding processes reduce energy consumption and enhance product quality. The ultra-long service life design minimizes waste from discarded blades, perfectly aligning with green recycling and circular economy principles. This further amplifies the overall advantages of Mao Yue equipment in low noise and low energy consumption. Selecting these blades enables multidimensional optimization of grinding efficiency, powder quality, production stability, and operational costs, making your PE plastic recycling and processing lines more efficient, reliable, and sustainable.
Mao Yue PE grinding blades find primary application across core segments of the plastic recycling and deep processing industry chain, particularly suited for industrial production demanding high powder fineness, uniformity, and purity. First, in plastic recycling and regeneration, it is optimized for processing waste PE materials such as PE film, PE pipes, PE bottle caps, cable sheathing, and strapping bands. After efficient pulverization into fine powder, the material is directly supplied to downstream processes like regranulation, film blowing, pipe extrusion, or injection molding, enabling high-value circular utilization of waste plastics. Second, in the powder coating industry, these blades ensure the produced PE powder coatings exhibit high fineness (consistently controlled at 20-80 mesh), excellent flowability, and are free from scorching, impurities, or agglomeration. This perfectly meets the stringent powder quality standards demanded by processes like electrostatic spraying and fluidized bed impregnation. Additionally, in modified plastics and filler masterbatch production, it delivers uniformly ultrafine PE-based powder as an ideal carrier. This supports precise compounding and extrusion processing of PE-based filler masterbatches, color masterbatches, and functional masterbatches, enhancing product dispersion and performance consistency. Simultaneously, in chemical processing and rotational molding applications, the uniformly ground PE powder particles produced by blade grinding exhibit no agglomeration.
This makes them particularly suitable for rotational molding processes of large hollow containers, storage tanks, amusement park equipment, and similar products, ensuring uniform wall thickness, smooth surfaces, and freedom from bubble defects. Other high-demand scenarios include the fine grinding of PE plastic components from electronic waste, as well as laboratory samples and small-batch R&D testing where powder purity and particle size distribution are critically important.
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.
