1.What are the structural characteristics of the screw conveyor?
The spiral blades are welded on the rotating shaft of the screw conveyor. The blade surface type includes solid surface type, belt surface type, blade surface type, etc. according to the different conveying materials. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to give the spiral axial reaction force along with the material. When the machine is long, an intermediate hanging bearing should be added.
2.What is the relationship between the rotation direction of the screw conveyor and the conveyed material?
The direction of rotation of the screw conveyor shaft determines the direction of material conveying, but generally the screw conveyor is designed with rotating blades based on unidirectional conveying. When conveying in the reverse direction, the service life of the conveyor will be greatly reduced.
3.How to solve the problem of material blockage in screw conveyor?
Increase the discharge port or lengthen the end of the trough to solve the problem of poor discharge or too late discharge. At the same time, a small section of counter-rotating blades can be installed at the end of the discharge trough to prevent end blockage, such as the speed of the slow screw conveyor cannot be too large. Strictly implement the operating procedures to achieve no-load start and no-load parking; ensure continuous and even feeding; perform necessary cleaning of the materials entering the conveyor to prevent large or fibrous impurities from entering the machine and causing blockage. Install a silo level meter and a blockage sensor to achieve automatic control and alarm; open an anti-blocking valve on the discharge end cover. Minimize the lateral size of the intermediate suspension bearing as much as possible to reduce the possibility of blockage when the material passes through the intermediate bearing.
4.How to choose a suitable screw conveyor?
(1) Ideal screw conveyor output
What is your ideal screw conveyor output? It is easier to find the ideal screw conveyor price by determining this question.
(2) Screw conveyor model
After knowing the screw conveyor model you want, you can clearly find the specific screw conveyor price. How to know the screw conveyor model? You can read the screw conveyor technical parameters.
(3) Are there any requirements for the material of the screw conveyor?
(4) Whether the screw conveyor accessories are included in the purchase.
