Powder Screw Conveyor is a continuous conveyor for transporting powdery materials. Utilizing the rotational thrust of the screw shaft and blades, it propels the material smoothly axially within a closed cylinder, completely avoiding the problems of dust and material spillage associated with traditional conveying equipment. It is adaptable to horizontal, inclined, and vertical conveying, and can control conveying speed and material flow rate to ensure uniform and stable batching. Available in carbon steel, stainless steel, and polypropylene, it easily adapts to different types of material conveying. Single-unit lengths can reach 30 meters, supporting non-standard customization, and can be customized for production in conjunction with upstream and downstream equipment.
We can provide customers with different types of screw conveyors to meet your conveying needs.
Flexible screw conveyor: It has a certain degree of softness and can be bent arbitrarily. It can flexibly adjust the conveying height and is suitable for occasions where materials need to be conveyed at different heights.
Stainless steel screw conveyor: Made of stainless steel, it has the characteristics of corrosion resistance and easy cleaning, and is suitable for occasions with high hygiene requirements.
Double-axis screw conveyor: It has two screw shafts and can convey materials more stably. It is suitable for occasions with large conveying volume and high stability requirements.
Vertical screw conveyor: It is designed for vertical material conveying and can realize ascending or descending conveying, such as conveying from the ground to the upper floor or from the upper floor to the ground.
The Powder Screw Conveyor relies on a motor to drive the internal spiral blades to rotate. The material enters the barrel from the feed inlet, and the axial extrusion force generated by the rotating blades pushes the powdered material to move smoothly forward along the inside of the shell.
Feed port: The material enters the conveying pipe of the screw conveyor through the feed port.
Spiral blade push: Inside the conveying pipe, the spiral blades installed on the spiral shaft begin to rotate. The rotation of these spiral blades pushes the material forward.
Material conveying: The material is wrapped by the spiral blades and is pushed forward along the direction of the conveyor as the spiral shaft rotates.
Discharge port: Finally, the material reaches the discharge port and is released from the conveyor to complete the conveying process.
The Powder Screw Conveyor mainly consists of a drive unit, inlet, conveying cylinder, spiral blades, main shaft, outlet, and frame. The overall structure is compact and simple, with the internal spiral blades as the core conveying component, the external cylinder being sealed and dustproof, and bearing seats at both ends supporting its operation.
Screw shaft: It is the core component of the conveyor and is responsible for transmitting power and rotational force.
Spiral blade: It is installed on the screw shaft and is responsible for pushing the material along the direction of the conveyor. It is mostly spiral-shaped and helps to wrap and push the material.
Conveying pipeline: It provides a channel for material transportation and maintains the directionality of the material during the transportation process. It has carbon steel, stainless steel or other special materials.
Transmission device: It provides the power required by the screw shaft to drive the spiral blade to rotate.
