Zipper feeder building material sand feeder chain conveyor, the spiral body mandrel of this machine is flexible, so the conveying route can be arranged according to spatial curves as needed. Depending on the length ratio of horizontal and vertical (large inclination) sections in the layout, its working principle is designed based on either an ordinary screw conveyor or a vertical screw conveyor. It is used in situations where the conveying route needs to be arbitrarily arranged according to spatial curves to avoid material transfer; when too much material or hard block material enters the machine casing, the spiral body will float freely without causing blockage; low noise. Mainly used for simultaneously completing horizontal and vertical conveying of materials. During vertical conveying, the rotational speed is generally required to be high and not lower than 1000r/min.

Screw conveyors are suitable for non-viscous dry powder materials and small granular materials (e.g., cement, fly ash, lime, grain, etc.), while shaftless screw conveyors are suitable for conveying viscous and easily entangled materials. Screw conveyors are divided into two types based on conveying form: shaft screw conveyors and shaftless screw conveyors. In terms of appearance, they are classified into U-type screw conveyors and tubular screw conveyors. Shafted materials (e.g., sludge, biomass, garbage, etc.). The working principle of a screw conveyor is that the rotating spiral blades push the material for conveying. The force that prevents the material from rotating with the screw conveyor blades is the material's own weight and the frictional resistance of the screw conveyor casing against the material. The spiral blades welded onto the rotating shaft of the screw conveyor come in different surface types depending on the material being conveyed, including solid surface type, belt surface type, and blade surface type. At the end of the material movement direction on the screw shaft of the screw conveyor, there is a thrust bearing to withstand the axial reaction force from the material. When the machine length is long, intermediate hanging bearings should be added. Zipper feeder building material sand feeder chain conveyor.
