Field case of screw conveyor manufacturer

Number of visits: Release date: 2020-03-28 10:52 source: admin

When the screw shaft rotates, due to the gravity of the material and the friction force generated by the wall of the tank, the material can only move forward along the bottom of the conveyor under the push of the blade, which is similar to the translational movement of the nut that cannot be rotated along the rotating screw. The movement of materials in the intermediate bearing depends on the thrust of the material moving forward behind. Therefore, the transportation of materials in the conveyor is completely a sliding movement. In order to make the screw shaft in a more favorable tension state, the driving device and the discharge port are generally placed at the same end of the conveyor, and the feed port is placed near the tail of the other end as far as possible. The rotating spiral blade moves the material and carries on the transportation. The force that makes the material not rotate with the screw conveyor blade is the material weight and the friction resistance of the screw conveyor shell to the material. According to the different conveying materials, there are three types of blade surface, such as solid surface, belt surface, blade surface, etc. A thrust bearing is provided at the end of the screw shaft of the screw conveyor in the direction of material movement to give the axial reaction force to the screw along with the material. When the length of the machine is long, the middle hanging bearing should be added.
