Custom Stainless Steel Screw Flight for Solid-Water Separation Equipment Factories, Factory
Product Description
Product Overview
This stainless steel screw flight is a core wear-resistant component specially designed for solid-water separation equipment, dedicated to livestock manure treatment systems. Manufactured from high-grade stainless steel via precision forming technology, it delivers outstanding corrosion resistance and structural strength, perfectly adapting to the humid, corrosive and high-fouling working environment of feces disposal. We provide three mature standard specifications with left-hand rotation, which are widely compatible with mainstream solid-liquid separators in the breeding industry.
This product is mainly applied to manure discharge, dewatering and solid-water separation in farms. It helps breeding enterprises realize dry-wet separation of feces, reduce sewage discharge pressure and meet environmental protection standards. With precise dimensional matching and reliable material performance, it ensures stable and continuous operation of solid-water separation equipment under long-term heavy-load working conditions, effectively lowering equipment maintenance frequency and replacement costs.
Material & Manufacturing Features
The screw flight adopts premium 304 stainless steel as the base material, which has excellent corrosion resistance, acid-alkali resistance and anti-rust performance, and can work stably for a long time in environments containing livestock manure, sewage and corrosive components. The integral forming process ensures uniform helical shape, smooth surface and no burrs, which reduces material adhesion and facilitates daily cleaning and maintenance.
The left-hand rotation structure is customized according to the operation characteristics of solid-water separation equipment, ensuring smooth material pushing and stable conveying efficiency during the extrusion dewatering process. The blade edge is precisely trimmed to guarantee consistent fitting clearance with the separation equipment cylinder and avoid material leakage caused by excessive clearance.

Core Product Advantages
Made of high-quality 304 stainless steel with strong corrosion and rust resistance, fully adaptable to the humid and corrosive working conditions of livestock manure solid-water separation, with a much longer service life than carbon steel products.
Three standard specifications are specially developed for mainstream solid-water separation equipment with strictly controlled dimensional tolerances, enabling direct installation and replacement without secondary modification.
The optimized pitch design with left-hand structure ensures smooth material pushing, improves the extrusion dewatering effect of manure, and enhances the solid-water separation efficiency of equipment.
The integral forming process eliminates the risk of weld fracture, with high overall structural strength, stable operation under extrusion load and no easy deformation.
The smooth rolled surface reduces manure adhesion, prevents blockage, facilitates daily flushing and maintenance, and cuts down equipment downtime.
Standard models are mass-produced with stable quality and sufficient stock supply, which can meet the rapid replacement needs of breeding farms.
