Spiral shaft

Product Introduction

A Spiral Shaft is the core rotating component of screw conveyors, screw feeders, and spiral mixers, consisting of a central shaft with continuous or sectional helical flights that move, lift, and blend bulk materials through a trough or tube. Manufactured from high-grade stainless steel, carbon steel, or alloy steel and reinforced with a precision-applied Tungsten Carbide Coating on the flight surfaces, outer edges, and shaft wear zones, this component delivers exceptional hardness, abrasion resistance, and dimensional stability under continuous heavy-duty operation. The Tungsten Carbide Coating forms a metallurgically bonded layer that preserves flight profile and pitch accuracy even when conveying highly abrasive powders, granules, and slurries, making it a reliable component for material handling systems worldwide.

Applications

The Spiral Shaft is widely used across global industries including lithium battery materials, chemicals, minerals and mining, food and beverage, agriculture, plastics, construction materials, and waste water treatment. It is installed in horizontal screw conveyors, inclined screw feeders, vertical screw elevators, spiral mixers, and dosing feeders to transport and meter powders, granules, pellets, pastes, and sludge with precise volumetric control.

Advantages

The Spiral Shaft with Tungsten Carbide Coating delivers significant advantages for bulk material handlers around the world. First, the Tungsten Carbide Coating provides outstanding abrasion resistance on flight surfaces and outer edges, maintaining pitch accuracy and conveying efficiency up to five times longer than standard steel or chrome-plated shafts when handling abrasive mineral concentrates, ceramic powders, battery cathode materials, sand, and granular chemicals. Second, the hard, smooth carbide surface reduces friction and material adhesion on flights and shaft, preventing buildup, caking, and bridging that would otherwise reduce conveying capacity and require frequent cleaning stops. Third, the carbide-reinforced flight edges resist wear at the critical contact point with the trough, maintaining tight clearance and preventing material bypass that would degrade metering accuracy and volumetric efficiency. Fourth, the corrosion-resistant carbide layer protects the shaft from acidic powders, alkaline materials, moist bulk solids, and chemical additives, expanding the range of materials that can be safely conveyed without component degradation or product contamination. Fifth, the spiral shaft is available in continuous or sectional flight designs with customizable pitch, diameter, length, and shaft coupling configurations, and can be engineered to fit all major screw conveyor and feeder brands. Finally, by extending service life, reducing maintenance downtime, improving metering accuracy, and lowering total cost of ownership, the Spiral Shaft with Tungsten Carbide Coating delivers a strong return on investment for customers in every major global market.

FAQ

Q1: What materials can a Spiral Shaft convey?
A: The shaft transports and meters powders, granules, pellets, pastes, and sludge across battery materials, chemicals, mining, food, agriculture, plastics, construction, and wastewater treatment industries.

Q2: Why is Tungsten Carbide Coating applied to the Spiral Shaft?
A: The coating is applied to flight surfaces and outer edges to provide superior abrasion resistance, maintaining pitch accuracy and conveying efficiency up to five times longer than standard steel shafts.

Q3: What sizes and conveying capacities are available?
A: Shaft diameters range from 50mm to 500mm with lengths up to 6000mm, delivering conveying capacities from 1 to 100 cubic meters per hour with customizable flight pitch.

Q4: Can the Spiral Shaft fit different conveyor brands?
A: Yes, continuous or sectional flight designs are available with customizable pitch, diameter, length, and shaft coupling configurations, and can be engineered to fit all major screw conveyor and feeder brands.
