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.
Powder fineness ranges from 20-80 mesh (mainstream 30-60 mesh), delivering uniform particles without scorching. Compact footprint, low energy consumption (total power ~50kW), noise <85dB, and easy maintenance (quick-change modular blade blocks). As the entry-level model in the series, it offers the best cost-performance ratio, ideal for small factories or multi-variety small-batch production. Supports rapid material changeovers and laboratory-grade fine adjustments.
The Mao Yue PVC-500 Grinder primarily targets small-to-medium scale, high-flexibility, entry-level PVC recycling, testing, and product manufacturing applications. It is particularly suited for small factories, laboratories, or multi-variety processing enterprises with limited investment budgets, high powder quality requirements, and moderate production capacity needs. First, in small-to-medium PVC recycling scenarios, this model is optimised for processing common materials like waste PVC pipes, profile offcuts, floor tiles, cable sheaths, and door/window scraps. Through efficient, small-batch fine grinding, it produces uniformly fine, pure PVC powder free of impurities. This powder can be directly supplied to downstream processes like regranulation, pipe extrusion, profile extrusion, and injection moulding processes, enabling low-cost, high-value recycling of waste PVC. Secondly, it excels in laboratory/formulation testing applications, supporting ultra-fine grinding of small-batch PVC samples (with adjustable fineness from 20 to 100 mesh).
This makes it highly suitable for fine grinding needs in university labs, research institutions, new material enterprises, or during formulation development stages. It ensures a narrow particle size distribution and high purity, facilitating rapid verification of formulation stability, processing performance, and additive compatibility. Additionally, for entry-level PVC powder product manufacturing, this model enables small-scale trial production or entry-level batch manufacturing of PVC products like flooring, wall panels, and foam boards. It delivers uniformly fine powder free of scorching and impurities, compatible with small-scale calendering/extrusion lines. This ensures smooth product surfaces and consistent performance, helping SMEs rapidly enter the PVC powder products market. Finally, for multi-material flexible processing scenarios, it supports blending tests and fine pulverisation of PVC with small quantities of additives. Equipped with a convenient material changeover design and micro-adjustment gap system, it adapts to frequent material switching requirements for multi-variety, small-batch production.
