The main components of the screw conveyor which is used to transport granular materials in horizontal and slightly oblique directions are: semicircular trough and the spiral installed on the suspension bearing, which is driven by the driving device to rotate the spiral, and the materials are loaded into the trough through the feeding Hopper, and the materials are unloaded at the middle unloading port.
The vertical screw conveyor, which is used to transport scattered materials in the vertical direction, is spirally hung on the bearing at the top, while the lower part is centered by the self-aligning ballbearing. The trough body of the feeding section is a conical tube, and the rest is a cylindrical tube.The driving device at the top drives the screw to rotate, and the materials are fed into the top and discharged from the bottom.
Advantages of screw conveyor equipment
1.The structure is relatively simple and compact, easy to manage and operate;
2 The work can be tested, the maintenance is not very complicated, and the cost is low
3.Because the trough is closed, it is convenient to transport materials that are easy to raise dust, hot (200℃) and have strong smell, reducing environmental pollution and improving working conditions;
4.It can conveniently realize multi-point feeding and multi-point unloading;
5.A conveyor can deliver materials to two directions at the same time, I .e. centralizing to the center or away from the center;
6.In the conveying process, it can be combined with mixing, stirring, cooling and other technological processes;
7.The rigidity of the trough is relatively large, so it can well withstand a certain bending moment.
