On May 5, 2026, Haoxing's specially designed PPS crushing machinery equipment was successfully applied to the crushing and crushing of slag blocks on the polyphenylene sulfide production line. Regarding the successful application of Haoxing's special PPS crushing machinery equipment JPW252AB series in the production line of polyphenylene sulfide (PPS) for slag crushing and crushing, according to the company's technical leader, the company's technical team has made breakthrough progress in the "Annual Production 30000 Tons PPS Technical Renovation Project" by using JP-W252AB equipment. Based on the test data of the experimental samples, the equipment has successfully solved key technical bottlenecks such as fine crushing of 5-10cm large materials (≤ 3mm micron level) and flow matching. The project team has systematically overcome common challenges in PPS production through specialized design modifications and the establishment of a technical research team, significantly improving production efficiency.

Device Application
Crushing slag blocks and dredging production line: The equipment can efficiently process the lumps, aggregates or unqualified products formed after polymerization reaction, meeting the requirements of material particle size for back-end drying and packaging processes.
Online continuous production: adopting a closed design that integrates crushing, mixing, and pumping, it can be seamlessly integrated into existing production lines.
High hardness material response: PPS resin has high hardness and good wear resistance, requiring special high-strength wear-resistant components to adapt to long-term high load work.
Explosion proof and safety: Considering the flammability and explosiveness of PPS powder, the overall system solution in industrial scenarios must meet explosion-proof standards.
📈  Project Benefits
Equipment capacity improvement: greatly reducing dwell time through efficient crushing; Automated continuous operation significantly reduces downtime maintenance and effectively improves annual production capacity (such as the first batch of technical upgrades for the 10000 ton/year plant in Tongling Ruijia Phase I).
Optimization of operating costs: equipment wear-resistant materials extend the lifespan of core components and reduce spare parts costs; At the same time, it avoids the complex process of multi-stage crushing and conveying, reducing system energy consumption.
Product quality improvement: achieve stable fineness and particle size distribution, and improve the consistency of final product quality.
🔧  Key parameter matching
Grinding accuracy: The feed particles can be refined from 1-100mm to the 3 micron level.
Material selection criteria: The core grinding components are made of special hard alloys such as WC infiltrated tungsten carbide, which greatly improves the stability and durability of the equipment under harsh working conditions.
The equipment is widely used in PPS, PSU, PVC, ABS polymer resin and other project engineering, such as Walton Technology Co., Ltd., Ningbo Qixuan New Materials, Fujian Haichuan Plastics, Shanghai Huayi Group Test Four Chemicals Co., Ltd. and other users.
