The Drag Conveyor is a conveying device for continuously conveying powder, granules and small pieces of granular materials in a closed casing by means of a moving scraper chain. Since the scraper chain is buried in the material to be conveyed, it is called a buried scraper conveyor.
When transporting horizontally, the material is subjected to the thrust of the scraper chain in the running direction.The material is conveyed forward with the scraper chain to form a continuous overall material flow.
When lifting vertically, the material is lifted by the scraper chain in the moving direction.The continuous feeding of the lower part also causes the falling of the upper material to be subjected to continuous resistance, forcing the material to move upward with the scraper chain.
When these forces are greater than the friction between the material and the shell wall and the weight of the material, the material forms a continuous overall stream that is lifted.
