Share the structural characteristics of single-shaft and double-screw conveyors

Screw conveyor, also known as Jiaolong conveyor, is suitable for vertical and inclined conveying of various powder granular materials. The machinery can be customized according to customer requirements, so as to meet customer needs to the greatest extent. Recently, some customers have ordered double screw conveyors. Here, the conveyor manufacturer introduces the structural characteristics of the single-shaft and double-screw conveyors: the rotating shaft of the single-screw conveyor is welded with spiral blades, and the surface of the blades includes solid surface, belt surface, and blade according to the different materials to be conveyed. Face type and other types. The screw shaft of the single screw conveyor has a thrust bearing at the end of the material movement direction to give the axial reaction force of the screw with the material. When the length of the machine is long, an intermediate suspension bearing should be added. A double screw conveyor is a screw loading conveyor with two rotating shafts welded with rotating blades. To put it bluntly, it is to organically combine two screw conveyors to form a screw conveyor. The rotation direction of the rotating shaft of the screw conveyor determines the conveying direction of the material, but in general, the screw conveyor is designed to design the rotating blades in accordance with the single-item conveying.

From screw conveyor to scraper conveyor application

In the development process of the conveyor, it has experienced the development era from screw conveyor to scraper conveyor to air conveying chute.　　 At first in the 1930s, screw conveyors entered China. It began to be applied to industrial production. At first, it was applied to the cement industry, and slowly it was also applied in the chemical industry. Later, it was applied to various industries such as agriculture, food, and mining. Until now, the screw conveyor is also used for conveying. The mainstay of machinery.　　 But the times are constantly developing, and the screw conveyor has shortcomings in the process of using it. It was also constantly exposed, so the scraper conveyor was developed later. The development of the scraper conveyor is later than the screw conveyor, but the application of the scraper conveyor in some industries such as mining is better than that of the screw conveyor. The buried scraper conveyor is remarkable in conveying materials such as dust, small particles and small blocks. Horizontal and inclined conveying, when conveying materials, the conveying distance is long, and it can convey a lot of hot materials.
