Introduction

In industrial material transportation operations such as those in the chemical, building materials, new energy, and food industries, traditional equipment like belt conveyors, screw conveyors, and bucket elevators are mostly of open or semi-open transportation structures. They have long suffered from problems such as dust leakage, material spillage and loss, impurities mixing in, and workshop pollution. Tubular Drag Conveyors, relying on a fully enclosed pipeline transportation structure, break through the structural limitations of traditional equipment and achieve dust-free, loss-free, and pollution-free transportation from the root cause, suitable for various complex industrial conditions.

Tubular Drag Conveyors

Tubular Drag Conveyors is a new type of closed-loop continuous conveying equipment. Its core operating principle is: through the motor driving the chain and the scraper to rotate in the closed pipeline, the scraper drags and pushes the materials to complete the fully automatic conveying operations in horizontal, vertical, inclined, and multi-turn points.

Compared with open-loop conveying equipment, the biggest feature of Tubular Drag Conveyors is the fully enclosed pipeline operation and no exposed conveying links, which fundamentally eliminates the problems of material spillage and dust diffusion. At the same time, the equipment has a compact structure and stable transmission, and can be adapted to various dry and wet materials such as powder, granules, and small blocks. It has strong versatility and is the core equipment for modern dust-free conveying and energy-saving conveying.

Applications of Tubular Drag Conveyors

Chemical industry

The materials in the chemical industry are mostly powder and granular raw materials, such as fertilizer raw materials, resin particles, pigment powder, chemical additives, inorganic salt powder, etc. They generally have the characteristics of easy dust flying, easy moisture absorption, easy pollution, and slight corrosiveness, and the environmental protection requirements in the production workshop are extremely high. The fully enclosed conveying structure of Tubular Drag Conveyors can completely avoid the pollution of chemical dust leakage to the workshop and the environmental over-limit problems, and at the same time prevent the introduction of external impurities into the materials, ensuring the purity of chemical raw materials.

Building materials and mining industry

The materials in the building materials and mining industry are mainly large-density, high-hardness granules and powders, including cement, fly ash, limestone powder, quartz sand, mineral particle, gypsum powder, etc. They have extremely high requirements for the wear resistance, stability, and load-bearing capacity of the conveying equipment. Tubular Drag Conveyors adopt thickened pipelines and wear-resistant scraper chains, which are resistant to impact and wear, and can be adapted to heavy materials for continuous conveying for a long time without deformation or failure. At the same time, it can achieve long-distance, large-angle, and multi-turn-point conveying, suitable for the complex layout of mining and building material factories.

Food and feed industry

Tubular Drag Conveyors can be customized with food-grade stainless steel material, with no dead corners, easy cleaning, and no residue. The closed conveying process isolates water vapor, dust, and debris, fully meeting the safety production standards of food and feed industries. At the same time, the equipment operates smoothly, does not cause material fragmentation or classification, ensures the integrity of the materials, and effectively reduces the material loss cost in food and feed production.

Other industrial scenarios such as metallurgy, medicine, etc.

In the metallurgy industry for transporting metal powder and mineral powder, the pharmaceutical industry for transporting powder and raw particle materials, and the transportation of chemical auxiliary materials, plastic particles, and construction powder in the pharmaceutical and building materials factories, Tubular Drag Conveyors are also highly adaptable.

Core equipment advantages of Tubular Drag Conveyors

Fully enclosed dust-free conveying

The entire machine adopts a closed pipeline structure, with no material exposure or dust dispersion throughout the process. This fundamentally solves the dust pollution problem in the workshop and avoids environmental supervision risks. At the same time, it improves the working environment in the workshop and reduces the risk of dust explosion, suitable for all industrial production scenarios with high environmental protection requirements.

Flexible layout

Tubular Drag Conveyors break through the limitations of traditional equipment conveying, and can achieve horizontal, vertical, inclined, S-shaped, multi-turn-point multi-dimensional conveying, without being restricted by the space of the factory building, the height of the equipment, and the layout of the site.

Stable and durable operation

The equipment adopts a chain and scraper transmission structure, with a simple and stable structure, wear-resistant and durable. During operation, it is not prone to blockage, jamming, or deviation, and has a very low failure rate. The equipment has low noise, low energy consumption, and simple daily maintenance, requiring no frequent replacement of parts, and the service life is much longer than traditional conveying equipment, significantly reducing the enterprise's later operation and maintenance costs.

Strong versatility One piece of equipment can be compatible with various materials such as powders, particles, small blocks, dry-wet mixed types, etc. Both heavy and light materials can be transported stably. There is no need to replace the equipment to adapt to multiple types of production lines. The equipment has strong versatility and extremely high cost performance.

Tubular Drag Conveyors vs Traditional Conveying Equipment

Comparison with Belt Conveyors

Belt conveyors have open design, resulting in high dust emission, prone to deviation, and serious material leakage, and cannot achieve vertical transportation; while Tubular Drag Conveyors are dust-free and dust-free, flexible in layout, and can perform vertical feeding, without being restricted by the site.

Comparison with Screw Conveyors

Screw conveyors are prone to blockage, have a lot of residues, have a short conveying distance, and high energy consumption; Tubular Drag Conveyors have a longer conveying distance, no residues, less material blockage, and stronger stability in large-scale transportation.

Comparison with Bucket Elevators

Elevators can only perform vertical transportation and cannot turn; their layout is simple, and there is a large dust hazard; Tubular Drag Conveyors can perform multi-dimensional transportation and are adaptable to multiple turning points, and have comprehensive leading performance in terms of sealing and working condition compatibility.

Summary

Tubular Drag Conveyors, with its multiple advantages such as closed and environmentally friendly operation, zero loss, flexible layout, stable operation, and strong versatility, has completely solved the various problems of traditional industrial conveying equipment, and is widely applicable to all industries including chemical, building materials, new energy, food, metallurgy, and medicine.
