Chain Conveyor
The scraper conveyor is a continuous conveying equipment that uses scraper chains as the traction component and a chute as the material carrying and guiding channel.
The scraper conveyor is a continuous conveying equipment that uses a scraper chain as the traction component and a chute as the material carrying and guiding channel. Its core structure consists of the scraper chain (formed by the connection of the scraper and the chain), the chute, the driving device, the tensioning device, and other components. During operation, the driving device drives the scraper chain to run cyclically within the chute, and by utilizing the friction or pushing force between the scraper and the materials, it conveys coal, ores, sand, stones, grains and other bulk solid materials along the length of the chute continuously to the target position.
This equipment has the characteristics of a sturdy structure, stable conveying capacity, and the ability to adapt to harsh working conditions (such as environments with high dust and high humidity). It is widely used in industries such as mining (especially in the mining face and drifts of coal mines), metallurgy, building materials, chemical industry, and grain processing, and is one of the key equipment for achieving efficient transportation of bulk materials.
Characteristics of the scraper conveyor：
Maximum conveying distance: less than 50 meters
Load-bearing depth: 250 – 800 mm
Sturdy and durable, with flexible conveying path adaptability, fully enclosed dust-free conveying, stable and reliable transmission system, convenient maintenance and modular design, wide material compatibility, adaptability to multiple industries, adaptability to special environments, efficient and energy-saving drive technology, intelligent collaborative operation.
Suitable for various materials, with the option of stainless steel.
Applications of the scraper conveyor：
The scraper conveyor is a device that uses a scraper chain as the traction component and realizes the transportation of bulk materials through the continuous movement of the scraper in the chute. It is composed of core components such as the head drive section, tail drive section, scraper chain, chute, tensioning device, etc. With its sturdy structure, stable conveying capacity, and adaptability to complex working conditions, it plays a key role in multiple industries.
1. Mining industry
The mining industry is the most widely used field for scraper conveyors, especially in underground mining scenarios. In coal mining, the scraper conveyor is one of the core equipment in the comprehensive mining face, together with the coal shearer and hydraulic support, forming a “three-machine matching” system. It can directly receive the coal mined by the coal shearer and continuously convey it from the working face to the transfer machine or transportation machine alley, achieving integrated coal mining and transportation operations. Due to the complex environment underground, including dust, humidity, and impact, mining-use scraper conveyors usually use high-strength wear-resistant materials and have explosion-proof capabilities to ensure safe and stable operation under harsh conditions.
In non-mining mines, such as metal and non-metal mining, the scraper conveyor also undertakes important material transportation tasks. It can be used to transport bulk materials like ores and gangue, adapting to different working conditions in underground or open-pit mining sites. For example, in underground mining of metal ores, the scraper conveyor can transport the blasted ores from the working face to the crushing equipment, providing raw materials for subsequent beneficiation processing; in open-pit mining sites, the scraper conveyor can be combined with other equipment to achieve short-distance transportation and stacking of stone materials.
Advantages: Stable operation in harsh environments, large conveying capacity.
2. Industrial sector
In the building materials industry, scraper conveyors are widely used for the transportation of materials such as cement, lime, sand, and stone. In the cement production process, the scraper conveyor can transport raw materials (such as limestone, clay, iron powder, etc.) from the raw material storage area to the clinker mill, transport raw cement from the clinker storage area to the cement mill, and also be used for transporting cement products. Due to the hardness and wear resistance of the materials in the building materials industry, the scraper conveyors used in this industry usually adopt wear-resistant liners and high-strength scraper chains to extend the equipment’s service life.
In the power industry, scraper conveyors are mainly used to handle solid waste such as fly ash and coal slag. In thermal power plants, the fly ash and coal slag produced after coal combustion need to be promptly cleared and transported. The scraper conveyor can transport these wastes from the bottom of the boiler or dust removal equipment to storage areas or processing equipment, achieving centralized treatment and reuse of waste materials and reducing environmental pollution.
In the metallurgical industry, a large amount of raw materials and by-products are produced during the production process, such as coke, ore, and steel slag. The scraper conveyor can be used for the transportation of these materials. For example, in steel mills, the scraper conveyor can transport coke from the coke storage area to the blast furnace, transport ore from the material storage area to the sintering machine, and also be used to transport steel slag generated during the steelmaking process, ensuring the continuous operation of metallurgical production.
Advantages: Sturdy and durable, long service life, good sealing performance, strong environmental adaptability.
3. Agricultural sector
In agricultural production, scraper conveyors can be used for the transportation of bulk materials such as grains, feed, and straw. In the grain storage process, the scraper conveyor can transport harvested grains from the transportation vehicle to the grain storage area or from the grain storage area to the processing equipment; During the feed processing process, the scraper conveyor can transport various feed raw materials (such as corn, soybean meal, bran, etc.) in proportion to the mixing machine, granulator, and other equipment, achieving the automation of feed production. Agricultural scraper conveyors usually have a relatively simple structure, are easy to operate, and can adapt to the production environment in rural areas.
Advantages: Simple structure, easy operation, strong adaptability.
