Tubular Screw Conveyor ÇKTH Çift Kartal: High-Performance Enclosed Transport

The tubular screw conveyor ÇKTH (also known as a tube auger) manufactured by the leading Turkish brand Çift Kartal is the benchmark for reliability in bulk material handling. This equipment is specifically designed for the continuous movement of powdery, fine-grained, and granular raw materials that exhibit low adhesive properties (non-sticky materials).

Thanks to its completely enclosed cylindrical design, the tubular screw conveyor ÇKTH can satisfy the most stringent requirements across all industrial sectors. It allows for the transportation of products not only in a strictly horizontal position but also at significant angles of inclination (including perpendicular or near-vertical lifts), ensuring the uninterrupted flow of your plant’s technological process.

Operating Principle and Advantages of the Cylindrical Design

Traditional U-trough screw conveyors have a significant drawback: as the angle of inclination increases, conveying efficiency drops sharply due to the material falling back down the trough. The tubular screw conveyor ÇKTH completely eliminates this problem.

Its working component (the flighting or screw) rotates inside a solid, seamless steel tube. Because there is minimal clearance between the edge of the screw flighting and the internal wall of the tube, this conveyor can transport products at much higher speeds. The material moves in a solid, continuous flow, which prevents segregation and reduces the mechanical degradation of granules. This is absolutely critical for preserving the quality of pelleted feed or fragile extruded products during transit.

The Ultimate Solution for Precision Dosing

Very often, a tube auger conveyor is utilized as a volumetric feeder or doser. It is typically installed directly beneath a finished product bin ÇKKB to extract the accumulated material. The primary advantage of the ÇKTH series in this process is the ability to maintain precise control. The dosing speed is regulated using an inverter (Variable Frequency Drive – VFD), which alters the motor’s RPM. This allows operators to perfectly synchronize the product output with downstream packaging machines, bagging scales, or industrial mixers.

8 Reasons to Choose the ÇKTH Tubular Screw Conveyor

Investing in high-quality conveying equipment is an investment in the overall stability of your manufacturing facility. By choosing this specific powder dosing auger, you gain:

1. High Throughput Capacity: The optimized screw pitch allows large volumes of raw material to be moved in minimal time.

2. Maximum Hygiene: The fully enclosed transport path eliminates dust emissions into the factory environment and protects the internal product from moisture and dirt.

3. Operational Safety: The absence of exposed moving parts brings the risk of personnel injury down to zero.

4. Low Energy Consumption: Premium gear motors and high-quality bearing assemblies minimize friction losses.

5. Silent Operation: The noise level during operation complies with the strictest European occupational health and safety standards.

6. Extended Service Life: The use of wear-resistant carbon or stainless steel guarantees years of trouble-free operation.

7. Minimal Maintenance: Very low periodic maintenance requirements and a highly reduced need for spare parts replacement.

8. Ease of Use: Simplified operation and fast, seamless integration into automated control systems (SCADA/PLC).

Industrial Applications for ÇKTH Tube Augers

The exceptional versatility of the tubular screw conveyor ÇKTH makes it highly sought after in almost all heavy and light manufacturing sectors:

🌾 Food and Agricultural Industry

• Flour, semolina, and pearl barley milling facilities.

• Animal feed and compound feed production plants.

• Biscuit, pasta, and snack manufacturing enterprises.

• Dry fruit and tea processing factories.

🧪 Chemical and Polymer Industry

Tubular conveyors are ideal for handling chemical reagents due to their air-tight construction. They are actively used in plants producing dyes, industrial detergents, washing powders, and plastics (such as conveying PVC granules).

🏗 Heavy Industry and Construction

• Cement Industry: Transporting dry cement, lime, and gypsum.

• Wood Processing Industry: Moving sawdust, wood chips, and supporting wood pellet production lines.

• Non-ferrous metallurgy plants and stone/soil mining facilities (transporting sand, mineral dust, and ash).

• Tobacco processing factories.

To create a comprehensive and highly efficient bulk handling line, we highly recommend combining our tubular screw conveyors with our vertical grain bucket elevators.

Frequently Asked Questions (FAQ)

What is the main difference between a tubular and a U-trough screw conveyor?

A tubular (tube) auger is completely enclosed, making it the ideal choice for transporting products at steep angles of inclination or even vertically, without allowing the material to spill over or fall back down.

Can the product feed rate be adjusted?

Yes. The tubular screw conveyor ÇKTH is frequently used for precise volumetric dosing. By connecting the drive motor through a frequency inverter (VFD), you can smoothly adjust the rotational speed of the screw, controlling the discharge volume with exceptional accuracy.

Are there any materials unsuitable for this conveyor?

It is designed primarily for raw materials with low adhesive qualities. For extremely sticky, wet, or highly cohesive materials that are prone to caking and wrapping around a central shaft, specialized shaftless screw conveyors might be a better alternative.
