Superior Chemical and Hygienic Resistance
The Kunwei Stainless Steel Shaftless Screw Conveyor is engineered for environments where carbon steel would fail due to corrosion or contamination. The use of premium stainless steel ensures that the equipment does not react with chemicals or acidic materials, maintaining product purity throughout the conveying process.
Polished Surfaces for Easy Sanitization
Our stainless steel units feature smooth, polished internal surfaces that prevent material buildup and bacterial growth. This makes them ideal for the food, pharmaceutical, and specialty chemical industries, where the ability to wash down the system and maintain a sterile environment is a regulatory necessity.
Structure
Stainless steel shaftless screw conveyor consists of shaftless screw blade, U-shaped helical groove, cover plate, lining plate, inlet/outlet port, discharge port and driving device.
Driving device: It is placed at one end of the screw conveyor. It adopts the form of direct connection between the motor reducer and the screw drive shaft. No coupling is required. It is easy to disassemble and maintain. The drive shaft can bear the load of bending distance and axial extrusion force at the same time.
Shaftless Spiral: The material is stainless steel or carbon steel.
Cover: Removable, easy to observe the material conveying condition and later machine maintenance.
Tank liner: The material is wear-resistant molecular polyethylene or 16 manganese, etc.
Inlet and outlet: There are two kinds of square and round. Generally, the form of inlet and outlet is determined by the user.
Technical Specifications
- Material Options: SUS304, SUS316, or SUS316L.
- Finish: Industrial acid-washed or food-grade mirror polish.
- Spiral Material: High-strength stainless steel alloy to prevent deformation.
Industrial Applications
Widely used in chemical processing, fertilizer production, food manufacturing, and pharmaceutical waste handling.
FAQ
Q: Which grade of stainless steel is best for my application?
A: We typically recommend SUS304 for standard food and mild chemical use. For highly saline environments or aggressive acids (like wastewater with high chloride), SUS316L is required for its superior pitting resistance.
Q: Does the shaftless spiral also come in stainless steel?
A: Yes. We offer both high-strength alloy steel (for wear resistance) and full stainless steel spirals (for total corrosion protection), depending on the chemical nature of your material.
Q: How do you ensure the interior is hygienic for food processing?
A: We provide specialized surface finishes, ranging from industrial acid-washing to 2B or mirror-polishing, to eliminate crevices where bacteria could grow.
