# Spiral Shaft
## Product Overview
Core Keywords: Spiral Shaft, Screw Conveyor Shaft, Lime Silo Discharge Shaft, Conveyor Central Shaft
The spiral shaft acts as the central load-bearing and driving core of shaft screw conveyors, widely supporting discharge feeding systems of lime silo, sand buffer silo and lime saturator. It adopts solid round steel as the main body, with wear-resistant spiral blades fully welded on the surface to push lime powder, quartz sand and other granular materials for stable quantitative conveying.
We provide carbon steel and stainless steel 304/316 spiral shafts to adapt to different working conditions. Carbon steel shafts with wear-resistant surfacing treatment suit general sand conveying; stainless steel shafts feature excellent alkali corrosion resistance, perfectly matching hydrated lime storage and feeding systems to avoid rust and material contamination. Customized length, shaft diameter and blade pitch are available to fit all sizes of vertical lime silo and horizontal lime silo discharge screw equipment.
## Product Features
1. High structural rigidity, not easy to bend and deform during long-distance operation, stable rotating operation
2. Integral welding of spiral blades and main shaft, high connection strength, no blade falling off during long-term material pushing
3. Optional wear-resistant overlay welding on blade surface, greatly reducing abrasion from sand and lime powder
4. Stainless steel anti-corrosion shaft optional, suitable for long-term conveying of moist, alkaline lime materials
5. Complete size customization, direct interchangeable matching with our supporting screw conveyor under lime silo
## Matching Application
- Discharge screw conveyor supporting vertical & horizontal lime silo
- Quantitative feeding equipment for lime saturator
- Sand conveying screw under sand buffer silo
- Dry powder dosing system for wastewater and desulfurization projects
