Shaft / shaftless screw conveyor

Screw conveyor by shaft diameter classification, can be divided into a shaft screw conveyor and no shaft screw conveyor. Shaftless screw conveyor is not easy to use the larger angle environment, the general level or small angle of the transport. Shaft screw conveyor disadvantages: easy to transport block, easy to wrap, too much sticky material.
There are shaft and shaftless screw conveyor mechanical principle, the role is basically the same, are used for the transport of materials equipment. Different types of screw conveyors are different, have their own unique little, they are based on customer requirements, the application of different industries from the ordinary screw conveyor improved. The non-shaft screw conveyor can deliver materials that are not or are not easily conveyed by conventional shaft screw conveyors and belt conveyors, such as granular and powdered materials, wet and pasty materials, semi-fluid and viscous materials, Materials, materials with special hygiene requirements.
shaftless screw conveyor anti-winding strong, because the machine without the central axis, so the transport of materials in the winding when there is no interference, can be easily and quickly transported, which a shaft screw conveyor cannot do.
Advantages: Shaftless screw conveyor compared with the traditional shaft screw conveyor, due to the usage of a non-center shaft design, the usage of a certain flexibility of the overall steel spiral push material, it has the following outstanding advantages: strong anti-winding. No center axis interference, for the conveyor belt, easy winding material has a special advantage.
As the spiral without shaft, the material is not easy to plug, the discharge port is not blocked, which can be lower speed operation, smooth transmission, reduce energy consumption. Torsional force is large, the amount of delivery.
Can be transported with conventional shaft conveyor and belt conveyor cannot or not easy to transport the material, such as granular and powdery materials, wet and paste materials, semi-fluid and viscous materials, easy to wrap and easy to block the material, with special hygiene required material.
Product shortcomings: easy to damage the leaves for two main reasons:
1. Because there is no intermediate shaft, all the force points are on the blade, so the thickness of the blade on the actual usage of the device has a very important impact. Choose a suitable thickness of the spiral blade, a direct impact on the usage of results.
2. Equipment transport materials, leaves and the bottom liner contact rotation, easy to wear.
Screw conveyor selection design needs to be based on different material properties to the right choice, the different properties of the material for the shaftless screw conveyor selection design plays a decisive impact. Decided to the future production of the practicality and efficiency.
