Scraper Chain Conveyor: Structure & Advantages

In heavy industries such as mineral mining, cement production, metallurgy, or coal processing, the transportation of blocky bulk materials, especially in harsh environments. Conventional conveyors sometimes cannot meet the requirements for durability and abrasion resistance. That is when the scraper chain conveyor becomes an optimal solution. With a special structure and the ability to work in harsh environments, this type of conveyor has affirmed its position as a reliable companion. Join Naltako to learn about the structure, advantages, and applications of this conveyor type.

What is a scraper chain conveyor?

A scraper chain conveyor is a specialized conveyor system that uses a chain as the main load-bearing component to move materials from one point to another. Its basic structure includes:

Chain system

This is the core component, usually high-strength chains with great durability. The chain is designed to withstand heavy loads and operate in dusty, high-temperature environments.

Scraper plates

The scraper plates (or scraper bars) are fixed to the chain, tasked with “scraping” and pushing material in the direction of the chain’s movement. These scraper plates are designed with shapes and sizes suitable for each type of material.

Material trough

Materials are contained in a closed trough, helping to prevent spillage and ensure environmental hygiene.

Motor and transmission system

The electric motor provides strong traction, helping the chain move continuously. The transmission system may include reducers to adjust the speed appropriately.

Common types of scraper chain conveyors today

Depending on material characteristics and usage needs, scraper chain conveyors can be divided into the following types:

• Bottom scraper chain conveyor: Most common, material is scraped on the trough surface.
• Tubular scraper conveyor: Material is transported in a closed tube, suitable for toxic materials or those requiring hygiene.
• Vertical scraper conveyor: Designed to transport material vertically, saving space.

What jobs are scraper chain conveyors suitable for?

Scraper chain conveyors are the optimal choice for:

• Transporting bulk, granular, powder materials: Suitable for moving cement, coal, ore, sand, gravel…
• Working in harsh environments: Withstands high temperatures, dusty, and corrosive environments.
• Transporting material uphill: The ability to scrape and push helps the conveyor operate effectively even on steep slopes.
• Transporting material over short and medium distances: Suitable for factories, workshops, ports…

Advantages of using scraper chain conveyors

Using scraper chain conveyors brings many outstanding benefits:

• High durability and longevity: Chains and scraper plates are made from wear-resistant materials with high durability, helping the system operate stably and durably over time.
• Stable operation: Scraper chain conveyors are less affected by external factors such as rain, wind, and dust, ensuring continuous transport.
• Minimize material loss: The closed trough and scraper plates help prevent material spillage, minimizing loss.
• Cost savings: Compared to other transport methods, scraper chain conveyors help reduce labor, fuel, and maintenance costs.
• Application flexibility: Can be combined with other lifting devices such as mini cranes to unload and transfer material into the conveyor system easily and effectively.
