Model 500 Fine Powder Mill for Masterbatch Production

The Mao Yue 500-type stands out with its ultimate craftsmanship: it features premium DC53 high-grade mold steel grinding discs (hardness HRC 62–64), offering superior toughness, fatigue resistance, and anti-chipping performance far exceeding conventional D2 steel, with a service life 1.5–2.5 times longer than standard discs; equipped with the only two units in China of imported Taiwanese professional CNC tool grinders for tooth-by-tooth precision grinding, ensuring micron-level blade angle consistency, razor-sharp edges, and extremely narrow particle size distribution for superior uniformity; it also supports professional refurbishing of dulled discs, with refurbishment costs only 1/4–1/3 of new discs, significantly reducing long-term tooling expenses. Each disc is dynamically balanced using German-imported high-precision balancing equipment, achieving industry-leading vibration control (demonstrating the famous “coin-standing” stability, comparable to high-speed rail), greatly reducing bearing and spindle wear, with noise levels below 85 dB, enabling reliable 24/7 operation and long-term powder quality consistency.

The standard water-cooling jacket + forced air cooling dual cooling system, combined with multi-point temperature sensors and PLC intelligent control, precisely maintains grinding chamber temperature at 50–70°C, completely eliminating overheating, sticking, yellowing, and performance degradation issues in heat-sensitive masterbatch polymers (such as PE-based, PP-based, EVA-based, TPU-based). The fully enclosed negative-pressure airflow conveying + pulse bag dust collector system achieves near-zero dust emission with a dust capture rate >99.9%, ensuring a clean workshop, safe production, and comprehensive employee health protection. Compared to the 600/800 models, the 500-type is more compact (footprint only 4–6 m²), with lower total power consumption (35–45 kW), making it the ideal choice for small-to-medium masterbatch plants, modified plastics factories, laboratories, or test lines, with a typical ROI period of just 6–12 months (thanks to electricity savings, fewer blade changes, reduced reject rates, and improved efficiency), truly delivering high-quality, high-efficiency, low-cost fine powder production for masterbatch applications.

The Mao Yue 500-type polymer masterbatch pulverizer is suitable for a wide range of high-precision fine powder production scenarios and serves as an ideal solution for the masterbatch and modified plastics industry. In masterbatch production, it efficiently grinds PE, PP, ABS, PS, PC, and other base materials, ensuring high dispersibility of pigments and additives for uniform coloring with no color difference, black spots, or fisheyes, delivering premium output quality. In the field of functional masterbatch and modified plastics, it excels at processing flame-retardant, antistatic, reinforced, conductive, and other high-performance masterbatches that demand extreme fineness and uniformity, with narrow particle size distribution and excellent dispersibility that significantly enhance downstream product performance. Additionally, it is widely used in recycling and re-granulation, quickly pulverizing waste masterbatch scraps, injection/extrusion waste, and off-cuts for reuse, substantially reducing raw material costs; it also produces uniform 30–60 mesh rotomolding powder and SPC flooring core layer powder perfectly suited for rotational molding processes and flooring substrate production. For laboratories or small-batch trial production, its compact design, high-precision temperature control, and flexible fineness adjustment make it the top choice for new formula validation, sample development, and small-scale masterbatch testing lines. Regardless of production scale, the Mao Yue 500-type consistently delivers stable, efficient, and cost-effective fine powder solutions to meet diverse application needs.
