Working principle of the screw conveyor When the buried scraper conveyor is transported horizontally, the material is subjected to the thrust of the scraper chain in the moving direction. When the internal friction between the layers of the buried scraper conveyor is greater than the external friction between the material and the groove wall, the material moves forward with the scraper chain. When the ratio of the height of the layer to the width of the groove meets certain conditions, the buried scraper conveyor is stable in the flow of the buried scraper conveyor.
When the buried scraper conveyor is transported vertically, it mainly depends on the arching characteristics of the material. When the material enclosed in the slotted conveyor is subjected to the thrust of the scraper chain in the moving direction, and the resistance of the lower part is continuously fed to prevent the upper material from sliding down, the buried scraper conveyor generates lateral side pressure, thereby increasing the material. The internal friction force, when the internal friction between the materials is greater than the external friction between the material and the wall of the tank and the weight of the material, the material of the buried scraper conveyor is transported upward with the scraper chain to form a continuous stream. Since the scraper chain of the buried scraper conveyor vibrates during the movement, the material arch of some materials is sometimes destroyed and formed. Therefore, the buried scraper conveyor causes a hysteresis to the chain during the conveying process, which affects the conveying capacity. .
Screw conveyor technology principle
The use of screw conveyor M296563 screw conveyor, including screw conveyor in the chemical plant is widely used, screw conveyor is mainly used to transport powder, granular and small pieces of materials, such as coal powder, soda ash, reclaimed rubber Powder, zinc oxide, calcium carbonate and small pieces of coal, etc., screw conveyor is not suitable for conveying materials that are easy to deteriorate, sticky and easy to agglomerate.
