In industries such as grain storage, nut processing, pet food production, and powder chemical engineering, the sealing, integrity, and stability of the material conveying equipment directly determine the production efficiency and product quality of the production line. Traditional belt conveyors and bucket elevators have many drawbacks such as high dust emission, high material damage rate, limited layout, and easy contamination of materials, which cannot meet the requirements of modern clean production and environmental protection reduction.
Tubular Drag Conveyors, with its core advantages of full-sealed transportation, low energy consumption, flexible layout, and convenient operation, has become the mainstream equipment for conveying particles, powders, and easily crushed materials. This article will comprehensively analyze the application value of Tubular Drag Conveyors from the aspects of equipment principle, core parameter selection, traditional equipment pain points, new technology upgrades, and multi-industry application scenarios, providing professional references for enterprise equipment procurement, renovation, and expansion.
Core Working Principle and Advantages
Equipment Working Principle
Tubular Drag Conveyors is a closed-loop, sealed transportation equipment. Its core consists of a power housing, a turning housing, a tensioning housing, a conveying pipeline, a sprocket, a chain, a scraper, and a power unit. The equipment uses the sprocket and chain as the core transmission structure, driven by the power unit to rotate the active sprocket, which in turn drives the chain and the evenly arranged scrapers to move in a closed pipeline in a circular motion.
After the material enters the closed pipeline from the equipment's feed port, relying on the stable pushing force of the scrapers, it moves along the preset conveying channel at a constant speed and is finally precisely discharged from the discharge port, achieving continuous closed, no scattering, and no drifting transportation throughout the process. At the same time, the equipment supports empty-load and half-load operation, which can adapt to complex working conditions such as uneven feed and short-term material interruption, and has extremely strong operational stability.
Core Advantages
Full-sealed dust-free transportation
The overall pipeline is sealed design, completely eliminating dust emission, leakage, moisture absorption, and impurity contamination problems, meeting environmental protection and food-grade clean production requirements;
Low material loss rate
The scraper's flexible pushing ensures no high-speed impact and no material crushing, maximizing the integrity of core materials such as nuts and feed particles;
Flexible layout
It can be arranged in various forms such as planar ring, vertical ring, top of the silo, and mobile layout, adapting to complex workshop layout;
Energy-saving, low consumption, durable
The equipment is lightweight, has high transmission efficiency, and has a lower operating energy consumption than similar conveying equipment, suitable for long-term continuous operation;
Easy expansion and renovation
No need to replace the entire machine, only by replacing the pulley and V-belt, the running speed can be adjusted, adapting to the demand for later capacity upgrade.
Mainly Applicable Materials and Industries
Tubular Drag Conveyor has extremely strong versatility and can be adapted to various characteristic materials. Its core covers three main fields: first, for grain storage such as wheat, corn, and rice; second, for food processing such as nuts and dried fruits; third, for livestock production such as expanded pet feed and granular feed. It can also be adapted to various dry powder and granular materials in the chemical and construction industries.
Tubular Drag Conveyors Selection Parameters
Selection by Material Characteristics
Dry, non-migratory, and non-abrasive materials
For ordinary powders and dry granular grains, a small-sized model can be selected, combined with a high-speed operation mode of 10-17m/min, suitable for short-cycle, high-frequency transportation operations, and improving basic production capacity.
Easily crushed, prone to contamination, and medium-flowing materials
For core materials such as nuts and pet feed, high-speed transportation is prohibited. These materials are loose in texture, prone to fragmentation and easy to be sorted. Therefore, medium-sized or large-sized machines need to be selected, along with medium-low speed operation mode, to reduce the friction and impact between the scraper and the materials, as well as between the materials and the pipeline. The material damage rate should be strictly controlled to ensure the quality of the finished products.
Long-term capacity expansion selection techniques
Most enterprises have lagged behind in equipment upgrading compared to capacity expansion. Frequent equipment replacement is extremely costly. Industry senior selection scheme recommendations: Initially, prioritize the selection of large-sized machines and low-speed operation. Reserve sufficient production capacity in the equipment, and when the capacity is to be increased later, there is no need to disassemble and assemble the entire machine. Just by simply replacing the pulley and V-belt, the chain running speed can be quickly increased, achieving low-cost expansion, and significantly improving the equipment service life and adaptability.
Adaptation solutions for complex feed conditions
In actual production, feed surges and uneven feed are common problems, which can easily lead to equipment load fluctuations and transportation jams. For this condition, a surge hopper can be used in combination, which can balance the instantaneous feed volume and stabilize the transportation load. At the same time, relying on the unique no-load and half-load operation capabilities of Tubular Drag Conveyors, it can effectively buffer the equipment impact caused by feed fluctuations, even with medium-sized machines, it can ensure stable operation of the equipment.
Multi-industry application scenarios
Application in the grain storage industry
During the storage, transfer and transportation of grains, dust pollution, grain spillage and high labor costs are core pain points. Tubular Drag Conveyors with a fully enclosed transportation structure completely solve the problem of dust pollution in grain transportation, meeting the environmental protection standards of grain storage. At the same time, the equipment supports various layout forms such as plane layout inside the warehouse, vertical plane layout on the warehouse roof, and mobile type, perfectly adapting to the complex layout of grain storage, achieving automated and mechanized transportation of loose grains, significantly improving the efficiency of grain entry and exit, and reducing labor costs.
Application in the nut and pet feed industry
Nuts and pet feed are special materials that are fragile, prone to contamination and have high cleanliness requirements. High-speed transportation is prone to cause material fragmentation and dust contamination, and open transportation is prone to moisture and contamination by impurities, affecting the quality of the finished products.
Customized Tubular Drag Conveyors adopt medium-sized machines, medium-low speed stable transportation mode, and flexible scraper push structure, minimizing the material damage rate to the greatest extent; the fully enclosed pipeline design isolates external pollution, ensuring the hygiene standards of food and feed production. At the same time, the equipment can be adapted to multi-point feed and multi-point discharge requirements of production lines, flexibly adapting to nut deep processing and pet feed mass production lines, effectively reducing material loss and improving the qualified rate of finished products.
Application of powder and granular materials
For powder and granular materials with good fluidity, no wear and special requirements for cleanliness, such as those in the chemical, building materials and dry powder food industries, small-speed Tubular Drag Conveyors are the optimal choice. The equipment has stable high-speed transportation, no dust dispersion, no material waste, low energy consumption and high efficiency, and can be adapted for 24-hour continuous industrial operations, meeting the needs of large-scale powder material transportation.
