Screw conveyor is characterized by simple structure, the cross-section of small size, good sealing, reliable, low cost, easy to intermediate loading and unloading screw conveyor, conveying direction reversible screw conveyor works, would also have to two opposite directions transportation. Transport process of materials can also be stirring, mixing, heating and cooling operations. Adjustable material flow through the loading and unloading gate. But not transport perishable viscous, easy caking and large pieces of material. Easily broken during transportation of materials, spiral and trough easy to wear. Larger units of power. Use to maintain the seal between the trough and screw and trough proper clearance. Screw conveyors operate at far more than the resonance condition, good amplitude stability. Change the frequency of exciting force, while adjusting the eccentric shaft and the eccentric mass centroid location, ensure constant amplitude of exciting force. With the increase of the frequency can screw conveyor, the conveying speed of the material decreases. Screw conveyor to change the frequency of the exciting force, while maintaining the quality of the eccentric shaft and the eccentric centroid constant screw conveyor chart, the increase in the frequency of the exciting force at the same time, the amplitude of the exciting force will also increase accordingly . With increasing frequency, the conveying speed of the material gradually increases accordingly. Cause screw conveyor capable of conveying the material due to the presence of green tea force between the material and the trough. Directly affects the size of the friction conveyor speed. Therefore, the coefficient of friction between the material and the trough of the transport properties of the material have a significant impact.
