Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically a screw conveyor for cement production. Background Technology

[0002] A screw conveyor for cement production is a mechanical device specifically designed for conveying powdery, granular, or small lump materials during the cement production process. It uses rotating screw blades to push materials along a fixed casing, achieving horizontal, inclined, or short-distance vertical conveying. It is widely used in cement plants for conveying raw materials, clinker, fly ash, pulverized coal, and other materials.

[0003] When using a screw conveyor, it needs to be connected to the discharge port of the silo. However, the inlet height of the screw conveyor is fixed. When there is a large difference between the height of the silo discharge port and the screw conveyor inlet height, it is necessary to manually tie the material bag or weld a section of material pipe to physically connect the silo discharge port and the screw conveyor inlet. This operation is time-consuming and labor-intensive. Therefore, a screw conveyor for cement production is proposed to solve the above problems. Utility Model Content
