Cooling Screw Conveyor

The cooling screw conveyor is a piece of equipment designed by Jiangteng specifically for high-temperature, sticky, or temperature-sensitive materials; by balancing conveying efficiency with temperature control, it helps reduce production costs.

Equipment Operating Principle

The cooling screw conveyor is not merely a conveyor; it is an intelligent temperature-control unit designed to integrate seamlessly into your automated production line. At the core of the equipment lies a dual-layer, water-cooled helical structure:

Synchronous Conveying and Cooling: As materials are propelled forward by the internal screw, a cooling medium continuously circulates through the external jacket and the hollow screw shaft, creating an enveloping heat exchange effect.

Patented Pitch Design: The unique screw pitch design optimizes the material's travel path and maximizes its contact surface area with the cooling medium, resulting in significantly enhanced heat exchange efficiency and ensuring more uniform, rapid cooling.

Intelligent Temperature Control System (Optional): Equipped with temperature sensors and automatic control valves, this system monitors conditions in real-time and automatically adjusts the cooling flow rate to maintain a stable target temperature without the need for manual intervention.

Why Is Our Structural Design More Reliable and Durable?

As a professional and responsible manufacturer, Jiangteng spares no expense on critical components to ensure your complete peace of mind:

1. Dual-Circuit Cooling (Jacket + Hollow Shaft): The barrel jacket and the hollow spiral shaft form two independent cooling circuits, creating a highly efficient, three-dimensional cooling network with temperature control capabilities far superior to single-circuit methods.

2. Modular, Segmented Blades: We utilize segmented spiral blades made from wear-resistant alloy steel. These segments can be replaced individually as they wear out, reducing maintenance costs by over 60% while ensuring easy installation.

3. Externally Mounted, High-Temperature-Resistant Bearing Housing: This design isolates the bearings from the high-temperature material zone. Coupled with high-quality seals, it effectively prevents dust ingress and material leakage, thereby extending the service life of the bearings several-fold.

4. Fully Enclosed Casing: This design completely eliminates dust leakage, meeting the stringent requirements of clean manufacturing environments. Simultaneously, it minimizes heat loss, thereby enhancing both cooling efficiency and workplace safety.

What Specific Challenges Can a Cooling Screw Conveyor Resolve for Your Industry?

Jiangteng’s cooling screw conveyors have been successfully deployed in numerous demanding operating environments. The following are several typical application scenarios:

1. Chemical Industry

Conveying high-temperature resins, catalysts, salts, and similar materials.

Solutions: Prevents material caking, decomposition, and equipment corrosion.

Case Study: Used to convey PET chips at 280°C; the discharge temperature is stably controlled below 80°C, allowing for direct packaging and eliminating the need for a separate cooling section.

2. Food Industry

Conveying chocolate, syrups, baking ingredients, and similar materials.

Solutions: Prevents material melting, sticking, and loss of flavor.

Case Study: At a confectionery plant, the system conveys sugar paste at 90°C, precisely cooling it to the optimal molding temperature; this resulted in a significant improvement in both product gloss and textural consistency.

3. Metallurgy / Building Materials Industry

Conveying cement clinker, slag, high-temperature dust, and similar materials.

Solutions: Prevents equipment burnout, mitigates severe dust emissions, and extends equipment service life.

Case Study: At a cement plant, the unit replaced traditional conveyors for the short-distance transport of clinker at 500°C; the equipment has operated continuously for two years without major repairs, and on-site environmental conditions have been vastly improved.

4. Environmental Protection Industry

Conveying dried sludge, biomass pellets, and similar materials.

Solutions: Prevents spontaneous combustion caused by residual heat and eliminates odors from flue gases.

Case Study: Assisted a client in cooling materials from 120°C down to a safe storage temperature during the conveying process, thereby completely eliminating storage-related safety hazards.

Equipment Parameters

Note: The above specifications represent standard parameters. Conveying capacity and final discharge temperature are closely dependent on specific material characteristics and cooling water conditions.
