In new energy battery material production, the post-drying conveying of ferric phosphate often faces three major challenges: wall adhesion, wear, and metal contamination. A 50,000-ton-per-year cathode material production line adopted twin-shaft stainless steel screw conveyors to achieve stable, clean, and continuous material transport.
Tailored Design for Material Characteristics
The conveyed material is dried iron phosphate powder with an approximate bulk density of 0.8 g/cm³, exhibiting high abrasiveness and sensitivity to iron content. The entire unit is constructed from 304 stainless steel, with blades undergoing nitriding hardening treatment to achieve surface hardness exceeding HV900, effectively resisting particle cutting. Replaceable wear-resistant liners installed on the inner shell walls extend equipment lifespan while reducing maintenance frequency.
Self-Cleaning via Dual-Shaft Interlocking
To address bridging and adhesion tendencies, a dual-shaft structure with equal diameters rotating in opposite directions is employed. The two screw blades interlock and mesh, simultaneously advancing material while scraping off deposits from the opposing blades. This significantly reduces residual buildup at the bottom, eliminating clogging risks at the source and ensuring continuous operation.
Sealing and Transmission Ensure Long-Term Operation
PTFE sealing strips are installed at both inlet/outlet ports and cover plates. The housing withstands pressures ≥±5000Pa, accommodating slight negative pressure conditions and effectively controlling dust leakage. The drive end employs a shaft-mounted reducer for direct connection, boosting transmission efficiency by 15%. During full-load operation at 25t/h, noise levels remain below 78dB, with no unplanned shutdowns over eight consecutive months.
This case demonstrates that for highly abrasive and viscous powders, the twin-shaft stainless steel screw conveyor offers outstanding advantages in contamination prevention, clogging resistance, and operational stability, making it a reliable choice for upgrading new energy material production lines.

Stainless steel screw conveyors have become essential equipment for solid material transportation in modern wastewater treatment plants due to their corrosion resistance, hygienic sealing, and stable operation. The following presents a generic engineering case study.
During the upgrade project of a medium-sized municipal wastewater treatment plant, multiple stainless steel screw conveyors were integrated into its core sludge dewatering system. For instance, within the sludge dewatering chamber, a steep-angle screw conveyor directly and continuously elevates wet sludge from the belt dewatering machine to an outdoor sludge silo. All material-contacting components are constructed from SS304 stainless steel, effectively resisting moisture, microorganisms, and potential corrosive substances in the sludge to ensure long-term durability in harsh conditions.
Additionally, in the downstream process section of the plant's screening area, shaftless screw conveyors are installed specifically for transporting screenings intercepted by coarse and fine screens. Their shaftless design prevents entanglement, while the stainless steel construction facilitates easy cleaning, enabling clean and efficient collection and transfer of screenings.
This case demonstrates how stainless steel screw conveyors reliably address the collection, short-distance transport, and centralized storage of solid waste—including screenings, grit, and dewatered sludge—in wastewater treatment processes. Beyond enhancing plant-wide automation and clean operation, their low maintenance requirements provide robust support for stable plant operation while reducing energy consumption and operational costs.
