The difference between shaftless screw conveyor and shaft screw conveyor

At present, screw conveyors on the market can be divided into shaftless screw conveyors and shaft screw conveyors. In order for everyone to have a better understanding of screw conveyors and to facilitate the purchase, Guo Sheng Xiao Bian specifically The differences existed in the conveyors are summarized and hopefully helpful to the users who need the conveyors. Please take a look!
First of all, to distinguish from their internal structure, in fact, from a literal point of view, it is sufficient to understand that there is no intermediate shaft in the middle of the shaftless screw conveyor. Usually, wear-resistant linings are used. Of course, its spiral blades are also better. The shaft screw conveyor is thicker, and the shaft screw conveyor is supported by a screw shaft in the middle, and the blades do not need to be thick enough to satisfy the material transportation.
The second is that the materials they need to convey will be different. The non-shaft screw conveyor generally conveys some viscous materials that are easier to wind, and they are easy to stick on the screw shaft. Therefore, the non-shaft spiral must be selected when conveying these materials. Conveyor, while the shaft screw conveyor has a wide range of conveying materials, it can also transport some powdery material.
Then there are also differences in the appearance of their appearance. Most of the non-shaft screw conveyors will use the U-shaped cross-section shape, and the shaft screw conveyor has two options, one is the tube type and the other is the U-shape. No harsh shaftless screw conveyors are required.
The last is the difference between the two forms of transport. The conveying angle of the shaftless screw conveyor generally cannot exceed 30 degrees, otherwise the material may be easily dropped when the material is conveyed, and the shaft screw conveyor may support more than 30 degrees due to the support of the screw shaft, and can even achieve Close to the vertical conveying material, of course, these are customized according to the actual needs of the user.
Here, Guo Sheng Xiao Bian also reminded the users who need screw conveyors to choose the screw conveyors that are suitable for themselves according to the characteristics of the materials they need to transport when purchasing screw conveyors. It is necessary to do well with the technicians of the manufacturers. After understanding the communication can be customized, and finally wish each user can choose their own wishful screw conveyor, Guosheng Machinery Company is willing to be your most faithful guide and explainer!
