PVC Pulverizer alloy steel blades and knives

The paramount advantage of Mao Yue PVC grinding machine tooth plates lies in their proprietary optimized high-wear-resistant alloy steel substrate, delivering stable hardness of HRC 58-62. undergoing multiple cycles of carburizing, quenching, and tempering. This process delivers outstanding wear resistance, impact resistance, and edge retention. Compared to standard market plates, service life extends by 2-3 times (maintaining sharp cutting force after hundreds to thousands of continuous operating hours), significantly reducing replacement frequency, downtime for maintenance, and labor costs. The precision high-density rack design (featuring multiple rows of parallel fine teeth or optimized angular arrangements) works in tandem with the moving disc to achieve “multi-point efficient shearing + intense friction” on PVC materials. This results in extremely high pulverization efficiency, boosting output by over 30% compared to traditional racks at the same power consumption. The finished powder fineness is stably controlled between 20-100 mesh, featuring uniform particle distribution, high sphericity, no noticeable coarse particles or fiber residues, high purity, no scorching, and no impurities. The unique multi-fin large-area structure provides excellent heat dissipation. Combined with the Mao Yue mill's dual air-cooling + water-cooling system, it effectively lowers grinding chamber temperature (PVC generates significant friction heat and softens/degrades easily), preventing plate overheating, deformation, material adhesion, or powder yellowing/degradation. It maintains lasting sharpness and stable performance even during 24-hour industrial continuous mass production. Installation and adjustment are straightforward—the fixed design incorporates precision bolts and gap adjustment mechanisms, supporting micron-level feeler gauge fine-tuning. Operation is simple and requires no frequent disassembly.

Mao Yue PVC grinding plates are widely used in PVC processing and recycling industries with stringent requirements for powder fineness, uniformity, purity, and production capacity. Primarily in PVC plastic recycling and regeneration, they are specifically designed to efficiently pulverize waste PVC materials (such as PVC pipes, profiles, window/door profile offcuts, vinyl flooring, cable sheathing, rigid sheets, bottle caps, and injection molding waste) into fine powder with high output and uniform particle size. The resulting powder directly feeds into high-value applications like regranulation, extrusion, injection molding, and blow molding, enabling a green closed-loop recycling system for waste PVC. Second, in PVC powder products and chemical modification, it produces high-quality PVC micropowder (high fineness, excellent flowability, agglomeration-free, decomposition-free). This powder is widely used in manufacturing PVC flooring, wall panels, cable compounds, leather, foam products, and modified masterbatches. It ensures stable downstream extrusion/calendering processes, resulting in products with smooth surfaces, no pores, and no color variation. Additionally, in grinding hard plastics and composite materials, this tooth plate enables fine pulverization of PVC blended with minimal additives (e.g., calcium carbonate, stabilizers), supporting production of functional PVC composite powders while enhancing dispersion and mechanical properties. Other high-demand applications include laboratory-scale PVC sample testing, carrier powder preparation for chemical additives, and environmentally sound fine grinding of PVC components from electronic waste—all scenarios sensitive to particle size distribution and purity. Leveraging Maoyue's 33 years of expertise in plastic crushing and grinding technology, modern processing equipment, and over 20 years of export experience, this tooth plate helps customers overcome PVC grinding fineness bottlenecks, reduce energy consumption, and improve recycled material quality. It perfectly aligns with green manufacturing demands under national circular economy policies and the “dual carbon” goals.
