Comparison of the advantages of the three types of screw conveyors

- Mar 23, 2018-

There are many types of screw conveyors, in addition to horizontal screw conveyors that can be made into U-shaped screw conveyors and tube screw conveyors, as well as vertical screw conveyors and shaftless screw conveyors, each of which has its own advantages. Need a simple grasp.


The characteristics of the horizontal screw conveyor are very obvious. On the one hand, the equipment is simple in structure and low in cost, reliable in operation, and easy to maintain. In addition, it has a small footprint. On the other hand, it can achieve sealed transmission through it to reduce the degree of environmental pollution.


In addition, the installation and disassembly of the horizontal screw conveyor must also be easy and easy to operate. In the conveying direction, reverse conveying can be realized, and two conveyings can be carried out at the same time. It is required that there should be a reverse spiral piece at the material outlet end to prevent the problem of material clogging; there can also be a choice of multiple conveying directions. .


The vertical screw conveyor is more adept at the short distance lifting of materials, and its conveying height can not be more than 8m; and solid surface spiral blades should be used. In addition, the vertical screw conveyor must also have a horizontal spiral feed to ensure a certain feed pressure.


The shaftless screw conveyor is also one of the screw conveyors. Its advantages in material transportation include two points. One point is that the shaft screw conveyor and the belt conveyor cannot convey the material because it has no central axis. It can transport easily windable materials, such as paste materials, as well as semi-fluid and semi-stick materials. Another point is that it is also applicable to some materials that are easy to wind and clog, as well as materials that have special sanitary requirements.
