In the fields of chemical engineering, building materials, food, and new energy, the transportation of powdery materials has long been plagued by problems such as dust pollution, material damage, limited transportation distance, and excessive energy consumption. Traditional spiral conveyors, due to design limitations, can only meet simple short-distance transportation needs and are difficult to adapt to the complex production conditions of modernization.
The Tubular Drag Chain Conveyors we have developed is a specialized equipment tailored for the characteristics of powdery material transportation. With advantages such as sealed transportation, three-dimensional layout, low loss and high efficiency, and multi-material compatibility, it comprehensively breaks through the bottlenecks of traditional equipment and becomes a breakthrough solution for powdery material transportation.
Tubular Drag Chain Conveyors
Core Definition And Working Principle
The Tubular Drag Chain Conveyors is a continuous conveying equipment with a closed pipe as the conveying channel and a chain + disc as the core traction component. Its working principle is that the motor drives the chain to perform a circular motion, and the wear-resistant discs on the chain push the materials to move along the preset trajectory of the pipe. It can achieve three-dimensional combined conveying, including horizontal, vertical, and inclined directions.
During the manufacturing process, we have optimized the shape and material of the discs multiple times to make them more in line with the contact with the powder materials, and to ensure a more uniform pushing force, so as to form a stable material flow in the pipe and avoid jamming and material breakage. This design logic is fundamentally different from the way the Screw Conveyor uses the rotation of the blades to push the materials - the frictional conveying of the screw conveyor cannot fundamentally solve the damage and dust problems of powder materials from the root cause.
Customized Structural Design
In the manufacturing of the Tubular Drag Chain Conveyors, we adopt a modular design combined with fully enclosed pipelines to give the equipment extremely high flexibility and environmental friendliness:
① Core Functional Components:The drive unit uses an efficient and energy-saving motor, which can precisely adjust the power according to the conveying volume; the tensioning device is equipped with an automatic adjustment system to ensure the stability of the chain tension in real time; the turner supports any angle from 0 to 90 degrees, suitable for complex factory layouts;
② Pipeline Material Selection: According to different industry requirements, we provide various pipeline materials such as food-grade stainless steel, wear-resistant carbon steel, and anti-corrosion nylon. The food industry can choose 304/316 stainless steel, and the chemical industry can customize anti-corrosion-coated pipelines;
③ Layout Adaptation Design:The pipeline can be designed to bend and loop according to the customer's factory structure. A single equipment can be equipped with multiple feed ports and multiple discharge ports, maximizing the utilization of workshop space and meeting the multi-station feeding requirements.
Why Tubular Drag Chain Conveyors Are The First Choice For Powder Material Conveying?
Fully Enclosed And Environmentally Friendly
We adopt a seamless welded closed pipeline design, with the materials being transported throughout the pipeline without any possibility of dust leakage. This design not only complies with national environmental protection standards and occupational health requirements, but also effectively protects the materials from external humidity and impurities, especially suitable for industries such as fine chemicals, food, and medicine that require high purity of materials.
In contrast, theScrew Conveyor, even with a sealed cover, will still have dust leakage at the feed and discharge ports. For powdery materials prone to dust, it simply cannot meet the environmental protection requirements - this is the core reason why many enterprises have abandoned the screw conveyor and chosen the Tubular Drag Chain Conveyors.
Low Loss And High Efficiency
● Low Energy Consumption: By optimizing the contact area between the discs and the inner wall of the pipeline, the friction resistance is minimized. Compared to the screw conveyor, the energy consumption of the Tubular Drag Chain Conveyorscan be saved by more than 30%. For example, in a working condition of transporting 10 tons of powder per hour, it can save tens of thousands of yuan in electricity costs annually;
● Low Material Loss:The residual amount of materials in the equipment can be controlled below 0.1%, with almost no material waste; at the same time, the low-speed and stable conveying method avoids the crushing of materials, which can significantly reduce quality losses for high-priced powdery materials such as titanium dioxide and lithium battery positive and negative electrode materials;
● Low Maintenance Cost:The core components use wear-resistant polyethylene and stainless steel materials. The disc life can reach 2-3 years, and the chain only needs a simple check every 3-6 months, with maintenance costs much lower than the frequent replacement of blades required for the screw conveyor.
Three-Dimensional Flexible Layout
The Tubular Drag Chain Conveyors we manufacture can achieve long-distance transportation of 60 meters horizontally and 40 meters vertically. It can also complete three-dimensional combined transportation with bends and inclinations, easily bypassing equipment and beams in the workshop, enabling vertical transportation from the first-floor storage to the third-floor production line, or multi-path transportation from multiple raw material storages to mixing equipment.
In contrast, the screw conveyor can only perform short-distance horizontal transportation. Once the workshop layout is complex, multiple equipment will be needed for transfer, which not only increases equipment investment but also increases the risk of material damage and dust leakage.
Wide Material Compatibility
The Tubular Drag Chain Conveyors can transport various powder materials with a bulk density ranging from 0.2 to 2.0 t/m³, from light food powder such as flour and milk powder, to heavy building materials powder such as cement and fly ash, to chemical powder such as resin and titanium dioxide, all can be transported stably.
For corrosive powder materials, we can replace the fluorine rubber discs and anti-corrosion pipelines; for sticky powder materials, we can customize anti-sticking coated discs to solve the problem of Screw Conveyors being unable to transport sticky powder materials and being prone to blockage. Currently, our Tubular Drag Chain Conveyors have been adapted to over 200 types of powder materials, covering 10+ industries such as chemicals, food, building materials, and new energy.
Simple maintenance
The Tubular Drag Chain Conveyors adopts a modular design. Daily maintenance only requires regular checks of the chain tension. The chain needs to be checked once every 3-6 months.
Even if the discs are severely worn and need to be replaced, it can be completed quickly. The modular component design allows maintenance personnel to quickly locate the problem, significantly reducing equipment downtime and improving production efficiency.
Limitations Of Screw Conveyor
Compared with the comprehensive advantages of Tubular Drag Chain Conveyors, screw conveyors have many limitations in the transportation of powdery materials that are difficult to overcome. These limitations stem from its inherent design flaws and cannot be simply resolved through simple modifications:
- Limited Conveying Capacity: It can only achieve short-distance horizontal transportation, with a conveying distance generally not exceeding 10 meters, unable to meet the requirements for long-distance and high-volume transportation;
- Insufficient Material Protection: The high-speed rotation of the screw blades will cause friction and compression with the materials, resulting in a high rate of powder material fragmentation and easy residue of materials in the material trough, causing waste;
- Poor Environmental Performance: The sealing performance is limited, and during powder material transportation, dust escapes severely, not meeting the environmental protection requirements of modern industry;
- High Maintenance Cost: The blades and material trough wear out quickly, and generally need to be replaced every 3-6 months, and the equipment is prone to blockage, making cleaning time-consuming and labor-intensive;
- Low Flexibility In Layout: It cannot achieve vertical or curved transportation, and is limited in application in complex factory buildings.
