Chain Scraper Conveyor Working Principle
The chain scraper conveyor transports bulk materials through a sealed trough using circulating chains with attached flights. Driven by a motor, the head sprocket pulls dual strands of chains, causing the welded flights to push materials along the trough via positive displacement. As the material layer is agitated by the flights, internal pressure and friction are generated. When this force exceeds the friction between the material and trough walls, the bulk material flows in a fluidized state (mass-flow principle) at a speed nearly matching the chain velocity (0.1-0.5 m/s).
This system excels in three-dimensional conveying and dust containment. Specially designed flight angles (typically 45°-60°) and trough profiles enable horizontal, inclined (≤45°), and vertical configurations. The fully enclosed trough with wear-resistant linings ensures minimal dust leakage. Unlike conventional chain conveyors that rely solely on frictional drag, the scraper mechanism forcibly propels materials, making it ideal for powders and granular materials with poor flowability (e.g., cement, coal powder, grains). Energy consumption is 30%-50% lower than screw conveyors for equivalent capacity.

Our chain conveyor, also known as a scraper conveyor or enclosed drag chain conveyor, is meticulously engineered to provide an efficient solution for handling powders, granules, and small lump bulk materials. Compared to traditional equipment, it demonstrates significant advantages across several key performance dimensions:
-
High Conveying Capacity, Space-Saving Design
The equipment features a compact structure while delivering impressive conveying capacity. To achieve the same material flow rate, it requires considerably less installation space than a conventional belt conveyor and is also more space-efficient than a screw conveyor. It offers a wide range of conveying capacities, flexibly meeting demands from several cubic meters to hundreds of cubic meters per hour. -
Long Service Life & Minimal Maintenance Cost
Key components, such as the conveying chain, are made from alloy steel and undergo scientific heat treatment processes, ensuring an extended service life of over five years under normal operation. Even wear parts like the chain rollers are designed for a service life typically not less than one year. This results in an average of less than one maintenance event per year, significantly reducing long-term operating costs and ensuring continuous, efficient production line operation. -
Low Energy Consumption, High Efficiency
The equipment ingeniously utilizes the internal friction between materials for conveyance, efficiently converting the work done by the driving components into effective transport work. The unique chain-and-flight pulling mechanism greatly reduces the resistance of material movement, resulting in overall energy consumption that is only 30% to 60% of a comparable screw conveyor under the same conditions. It is an ideal choice for energy-efficient, sustainable production. -
Fully Enclosed Structure, Safe & Eco-Friendly
The entire machine adopts a fully sealed design, completely preventing dust escape during conveyance and achieving dust-free conveying. It also offers good waterproof and rainproof performance. Easy to operate and safe and reliable in function, it creates a better working environment and fully complies with modern industrial environmental standards. -
Flexible Layout & High Adaptability
Various types of inlet and outlet points can be installed at any required location along the casing to suit specific process needs, offering great flexibility. The equipment supports multiple installation configurations, including horizontal, inclined (typically at angles ≤15°), or vertical setups. It can be arranged overhead, at ground level, or in a pit, perfectly adapting to complex workshop spaces and diverse process layouts.
Suitable for powdered, granular, and bulk materials such as cement, ores, coal, fertilizers, and grains.
Consider factors like capacity, material characteristics, temperature, and conveying distance. Our engineers provide model selection support.
Routine maintenance every 3-6 months, including chain tension inspection, scraper wear check, and lubrication of key components.
Yes, we provide explosion-proof motors and anti-static structures for flammable and explosive environments.

Both the FU Series and the MS Series (typically referring to en-masse or drag chain conveyors) are efficient chain conveying solutions, but they differ significantly in design, suitable materials, and typical applications. In short, the choice depends primarily on the characteristics of the material you need to convey.
| Aspect | FU Series Chain Conveyor | MS Series (En-Masse) Chain Conveyor |
|---|---|---|
| Working Principle | Conveys material using internal friction with smaller flights. | Drags material using larger flights that closely fit the housing. |
| Structure | Trough is relatively narrow and shallow; compact and lighter build. | Rectangular/box-type housing; more robust and heavy-duty construction. |
| Key Advantages | Excellent sealing, low energy consumption, cost-effective, ideal for continuous flow. | High capacity, superior impact resistance and abrasion resistance, built for harsh conditions. |
| Typical Materials | Powdery, fine granules, small pellets with good flowability. e.g., Cement, fly ash, flour, animal feed, plastic pellets. |
Dense, abrasive, or lumpy bulk materials. e.g., Coal, ore, slag, grain, wood chips, biomass pellets. |
| Selection Keywords | “Powder conveying”, “Dust-tight”, “Energy-efficient” | “Heavy-duty conveying”, “Abrasion-resistant”, “Lumpy materials” |
Chain, belt, and screw conveyors are three primary types of conveying systems, with core differences as follows:
-
Chain Conveyor: Uses steel chains as the traction/carrying component, equipped with attachments like flights, aprons, or plates. Key advantages include durability, high load capacity, suitability for high-temperature or abrasive materials, and fully sealed dust-proof operation. It is ideal for conveying powders, granules, small lumps, high-temperature materials, or abrasive substances.
-
Belt Conveyor: Relies on rubber or fabric belts as the carrying medium, suitable for regular packaged items or bulk materials with low density. Benefits include smooth operation, low noise, and long-distance conveying, but it is not resistant to high temperatures, prone to damage from sharp materials, and offers poor sealing.
-
Screw Conveyor: Moves materials via rotating helical blades, suitable for powders or non-sticky small lumps and capable of fully sealed operation. However, it has limited conveying distance and capacity, relatively high energy consumption, and is less adaptable to highly abrasive materials compared to chain conveyors.
In industries like mining, cement, and coal, chain conveyors are essential for transporting raw materials, semi-finished products, and waste slag, such as ores, coal, limestone, cement clinker, and slag.
Special design requirements include:
-
Exceptional Wear Resistance: Key components (e.g., chains, flights, troughs) must use high-strength wear-resistant steel or undergo wear-resistant treatment to handle highly abrasive materials.
-
Heavy-Duty Structure: The equipment requires reinforced design to withstand impacts from large lumps and high loads, ensuring greater strength and rigidity.
-
Dust Prevention and Sealing: For powdery materials (e.g., coal dust, cement), a fully sealed structure is necessary to prevent dust leakage, ensuring safety and environmental compliance.
-
High-Temperature Resistance: For materials like cement clinker, heat-resistant steel and specialized designs are needed to adapt to high-temperature environments.
