It has a high degree of customization.
Tubular Chain Drag Conveyor Structure

Tubular Chain Drag Conveyor Details








Tubular Chain Drag Conveyor Feature
Fully Enclosed Transportation
Our tubular chain drag conveyor enables the material to complete the entire transportation process within an enclosed pipeline, completely preventing dust from escaping. This not only meets the environmental emission requirements but also protects the occupational health of the on-site operators, avoiding health risks caused by dust pollution.
Low Wear Rate
Our tubular chain drag conveyor operates at a slow speed, with static or low-speed friction between the materials and the equipment. This not only effectively protects the particle shape of the materials, reduces the material breakage rate, but also minimizes the wear on the equipment itself, thereby extending the service life of the equipment.
High Production Capacity
Our domestically produced large-capacity tubular chain drag conveyor, when applied in building silos, can ac tubular chain drag conveyor, ency of 300 tons per hour with a single operation. It can meet the demands for large-scale and high-yield material transportation, helping you enhance the overall production operation efficiency.
Volume-based Conveying
Our tubular chain drag conveyor supports volumetric conveying, allowing for precise control of the material conveying volume according to production needs. This meets the requirements for material conveying accuracy in refined production, and is particularly suitable for industries such as food and chemical that have high precision requirements for ingredient mixing.
Large Spacing Design
Our tubular chain drag conveyor can be flexibly adjusted according to the feeding situation. The imported spacing can exceed 10 meters. It can easily adapt to the feeding layout of different production lines, and does not require you to make additional adjustments to the production line spacing, significantly improving the compatibility between the equipment and the production line.
Not Prone To Clogging
Our tubular chain drag conveyor relies on the thrust of the chain links and lateral side pressure to form a stable material flow. There are no dead zones in the pipeline, and the material is less likely to get clogged. Compared to screw conveyors, it has a stronger tolerance for overload and uneven feeding, fully ensuring the continuity of your conveying process.

Tubular Chain Drag Conveyor Applications
The Tubular Chain Drag Conveyor is suitable for a variety of materials. The following is a detailed summary of the applicable materials:
| Powdered materials | Common materials: cement, lime, carbon black, fertilizers, pigments, dyes, paints, titanium dioxide, iron oxide, ceramic powder, silica gel powder, activated carbon, etc. Features: During the transportation process of these materials by the tubular chain drag conveyor , they can achieve stable and continuous flow without causing wear to the equipment. The sealing performance of the tubular chain drag conveyor can effectively prevent dust from escaping, protecting the working environment and the health of the employees. |
| Granular Materials | Common materials: grains, sand, stones, ores, plastic particles (such as PVC, PP, PE, etc.), urea, ammonium chloride, ammonium bicarbonate, etc. Features: The tubular chain drag conveyor can ensure that these granular materials do not break or get clogged during the conveying process, guaranteeing the conveying efficiency. At the same time, its stable conveying performance also helps to reduce energy consumption and operating costs. |
| Small Particle Materials | Common materials: coal, mineral fragments, solid pesticides, fish oil, etc. Features: During the transportation process of these materials through the tubular chain drag conveyor, by appropriately adjusting the conveying speed and angle, it is ensured that the materials can flow smoothly within the pipeline. The flexibility and adaptability of the tubular chain drag conveyor enable it to handle block-shaped materials of different shapes and sizes. |
| Other Special Materials | Such as copper ore powder, coal powder, block phosphate, bauxite, clay powder, silica, dolomite powder, sawdust powder, glass fiber, etc. Features: These materials may possess unique physical or chemical properties, such as being fragile, flammable, or explosive. The airtightness and stability of the tubular chain drag conveyor make it an ideal choice for transporting these special materials. |
