What is a scraper conveyor?

Scraper conveyor is a type of material handling equipment designed to transport bulk materials, such as coal, sand, or grain, over long distances and inclines. It works by using a series of scrapers or flights attached to a chain that moves along a trough. These scrapers push the material forward, effectively conveying it from one point to another.

How does a scraper conveyor work?

A scraper conveyor consists of a channel or trough and a continuous chain or chain or belt with scrapers or flies. The scrapers or flies are attached to the chain or belt to help push or scrape the material along the conveyor path. When working, the chain or belt with the scrapers will continue to move in a closed loop, pulling the material along the conveyor path. The scrapers come into contact with the material and push it forward as the chain or belt moves.

Key components of a scraper conveyor

Trough: A channel-shaped structure that guides the material being transported.

Chain: A continuous chain that runs along the bottom of the trough.

Scrapers or flights: Attachments on the chain that push the material forward.

Drive mechanism: A motor or other power source that drives the chain.

Return idler: A device that supports the return run of the chain.

Advantages of using scraper conveyors over other types of conveyors

Scraper conveyors offer several advantages over other types of conveyors in certain applications. Here are some of the key advantages of using scraper conveyors:

1.Handling of Abrasive Materials: Scraper conveyors are well-suited for handling abrasive materials such as sand, gravel, and ores. The scrapers or flights help to move these materials without causing excessive wear on the conveyor components.

2.Handling of Sticky Materials: They are effective for transporting sticky materials that may adhere to the conveyor belt or chain. The scrapers help to prevent material buildup and ensure smooth material flow.

3.Durability: Scraper conveyors are known for their durability and robust construction. They are designed to withstand harsh operating conditions and heavy loads, making them suitable for rugged industrial environments.

4.Versatility: Scraper conveyors can be used for horizontal, inclined, or vertical transport of materials. They are versatile and can be customized to suit different applications and layouts.

5.Effective Cleaning: The scrapers on the conveyor help to clean the bottom of the trough or channel, preventing material buildup and ensuring efficient material transport.

6.Low Maintenance: While regular maintenance is essential, scraper conveyors generally require less maintenance compared to some other types of conveyors like belt conveyors. This can result in lower maintenance costs and less downtime.

Application of scraper conveyor

Scraper conveyors find a wide range of applications across various industries due to their ability to effectively transport bulk materials. Some common applications of scraper conveyors include:

Mining Industry: Scraper conveyors are commonly used in the mining industry for transporting coal, ore, and other minerals. They are suitable for handling abrasive materials and can operate in rugged mining environments.

Agriculture: In agriculture, scraper conveyors are used for handling grains, seeds, and other agricultural products. They can be employed in grain handling facilities, seed processing plants, and feed mills.

Cement Production: Scraper conveyors play a vital role in the cement industry for transporting raw materials such as limestone, clay, and gypsum. They help in the efficient movement of materials within cement plants.

Waste Management: Scraper conveyors are utilized in waste management facilities for handling municipal solid waste, recyclables, and other waste materials. They help in the efficient movement of waste for processing and disposal.

Chemical Industry: Scraper conveyors are employed in the chemical industry for transporting bulk chemicals, powders, and granular materials. They help in the safe and reliable movement of hazardous materials.

Recycling Facilities: In recycling facilities, scraper conveyors are used for handling recyclable materials such as plastic, paper, and metal. They assist in the sorting and transportation of materials for recycling processes.

Overall, scraper conveyors are robust and reliable equipment used for transporting bulk materials over short to medium distances. They are valued for their durability, versatility, and effectiveness in handling a wide range of materials in different industries.
