How does a chain conveyor work?
The chain conveyor (referred to as “scraper chain conveyor“) is a new generation of conveying equipment developed by Darko manufacturer. We integrate the advantages of similar domestic products and address common issues encountered in the practical application of general conveying equipment. Its principles are advanced, and its structure is innovative and rational, making it efficient and energy-saving. It is an ideal replacement for screw conveyors and has been widely applied in industries such as building materials, chemicals, thermal power, grain processing, mining, machinery, metallurgy, transportation, and ports.
There is internal friction and pressure between the particles of bulk materials. When the conveyor chain and its attachments move, the bulk material experiences a pulling force in the same direction as the chain’s movement, which increases the internal pressure between the particles. This, in turn, increases the internal friction among the bulk materials. When this internal friction exceeds the friction between the bulk material and the side walls of the trough, the materials will move forward in the direction of the chain’s motion. The increased internal pressure ensures a stable state among the layers of bulk material, resulting in a continuous flow like that of water. ( When the ratio of the height of the material layer to the height of the trough meets certain conditions, the flow of material is stable, and the flow rate is approximately equal to the chain speed.)

Darko’s highlight
| Characteristics | Description |
| Large carrying capacity | A scraper conveyor has the advantages of small size and large conveying capacity. It only needs 1/5 of the space of the belt conveyor or 2/3 of the space of the screw conveyor to transport the same flow of materials. Conveying capacity is 6m3/h~500m3/h. |
| Long service life & low cost | The scraper conveyor chain made of alloy steel by scientific heat treatment processing has a normal life of more than 5 years. And the life of the roller on the chain is not less than 1 year (the most vulnerable part of the whole machine). This ensures that the annual maintenance is less than once, which greatly reduces the use cost and improves the production efficiency. |
| Low energy consumption | The chain conveyor uses the internal friction of the material to convert most of the work done by the moving parts into effective work. The use of chain hook transportation greatly reduces the resistance of the material to it, so that its energy consumption is only 30% to 60% of the screw conveyor. |
| Sealed and secure | The whole scarper machine is fully sealed, making the dust seamless drilling, waterproof and rainproof, easy to operate, safe and reliable operation. |
| Flexible process | The chain machine allows a variety of types of inlet and outlet at any location in the casing. It can be elevated, ground or pit arrangement and can be mounted horizontally or uphill (≤15°). |
