Twin-Screw Conveyor

As a professional manufacturer and supplier of twin-screw conveyors, Jiangteng offers equipment specifically customized to suit diverse operating conditions. Our solutions are designed to effectively resolve issues such as material adhesion, clogging, and caking, thereby boosting conveying efficiency by over 40%.

Why Choose a Twin-Screw Conveyor?

1. No More Clogging Worries: By utilizing counter-rotating twin shafts, this equipment generates powerful shearing forces to break up caked materials, effortlessly handling viscous substances such as sludge, starch, and chemical waste residues.

2. Virtually Zero Residue: Precision gap control combined with synchronized twin-shaft propulsion ensures material residue levels remain below 0.5%, minimizing waste and simplifying cleanup.

3. Flexible, Space-Saving Installation: The Twin Screw Conveyor features a compact structure with a footprint just one-third the size of comparable belt conveyors; it can be customized for horizontal, inclined, or vertical layouts.

4. Wear-Resistant, Durable, and Long-Lasting: The screw blades are available in wear-resistant alloy options or with hard-facing treatment, while the casing supports stainless steel construction—offering superior resistance to corrosion and abrasion for more reliable, continuous operation.

5. Intelligent Control and Easy Maintenance: Supports variable frequency speed control and PLC-based remote monitoring; features a quick-opening access door design that reduces maintenance time by 60%.

How Does a Twin-Screw Conveyor Work?

Material Infeed: Material enters through the inlet and falls into the intermeshing zone located between the two shafts.

Bidirectional Propulsion: The two shafts rotate synchronously in opposite directions; their interlocking blades engage with one another to propel the material forward.

Anti-Clogging and Crushing: During rotation, the system automatically crushes material lumps and agglomerates, effectively preventing entanglement and blockages.

Stable Output: The material is conveyed uniformly toward the discharge port, thereby completing the continuous conveying process.

Whether dealing with corrosive chemical waste or high-moisture sludge, we meticulously optimize details—such as blades, materials, and seals—to ensure our equipment perfectly aligns with your specific requirements.

✅In-House Core Components

The spiral shafts, wear-resistant blades, and specialized reducers used in our twin-screw conveyors are all independently developed and manufactured in-house and are ISO 9001 certified.

Every batch of components undergoes rigorous dynamic balancing and wear resistance testing, resulting in a failure rate of less than 1% and ensuring highly stable operation.

✅Full Lifecycle Service

From model selection consultation and installation guidance to post-sales maintenance, we provide 24-hour technical support. We offer a 2-year warranty on core components, along with lifetime provision of spare parts and technical assistance, ensuring a worry-free purchasing experience.

✅Energy Efficiency & Cost Savings

Compared to many competitors' equipment, our products offer a 30–50% lower price point. Furthermore, thanks to structural optimization, our unit energy consumption is 15% lower than the industry average.

✅Modular Design

The machine casing features quick-access inspection doors, and the spiral shaft can be extracted as a complete unit. This allows for cleaning and component replacement without the need to dismantle the entire machine, significantly reducing downtime and labor costs.

Which Industries and Materials Are Suitable for Twin-Screw Conveyors?

FAQ

Q: What are the main differences between twin-shaft and single-shaft conveyors?

A: Single-shaft conveyors are suitable for loose, dry materials (such as grains or sand), whereas twin-shaft conveyors utilize the shearing action between two shafts to effectively handle viscous or prone-to-caking materials, ensuring more uniform conveyance and minimizing residual buildup.

Q: What is the maximum inclination angle supported by the equipment?

A: For standard models, the maximum recommended inclination is 30°. If a steeper angle is required, we can customize the design to include lifting flights or integrate the unit with a bucket elevator.

Q: What materials should be selected when conveying corrosive substances?

A: We recommend using 316L stainless steel for the casing and spiral shaft, and employing corrosion-resistant fluororubber for the seals to ensure long-term resistance against erosion by acidic or alkaline materials.

Q: What are the key considerations for the routine maintenance of a twin-screw conveyor?

A: Conduct monthly inspections of the flights for wear, ensure the seals remain intact, apply lubricant regularly, and promptly clean out any residual material from the interior of the machine when shutting down to prevent caking.

Q: How do I select the model that best suits my needs?

A: Please provide the following information, and we will develop a customized solution for you free of charge:

①Material name and characteristics (viscosity, moisture content, particle size)

②Required conveying capacity (tons/hour or m³/h)

③Conveying distance and installation angle
