The single-tube dust conveying equipment weighing quantitative feeder operates stably. The vertical screw conveyor is suitable for short-distance vertical conveying. The flexible screw conveyor consists of a flexible shaft and synthetic rubber blades, which are easy to bend and can be arranged arbitrarily according to on-site or process requirements for spatial conveying. Screw conveyor blades are available in wound and whole-drawn types. Wound blades can be made to any thickness and specification, while whole-drawn blades are not suitable for non-standard spirals.

From the perspective of material displacement direction, screw conveyors are divided into two main types: horizontal screw conveyors and vertical screw conveyors. They are mainly used for horizontal conveying and vertical lifting of various loose materials such as powders, granules, and small lumps. This type of screw conveyor is not suitable for conveying special materials that are prone to deterioration, highly viscous, prone to caking, high-temperature, pressure-sensitive, or highly corrosive.

Application scope and characteristics: (1) Screw conveyors are widely used in chemical, building materials, grain, and other sectors for conveying powdered, granular, and small lump materials. They are not suitable for conveying materials that are prone to deterioration, viscous, or caking. (2) The operating environmental temperature for screw conveyors is -20°C to 50°C; the conveyor inclination angle β ≤ 20°; the conveying length is generally less than 40m, with a maximum of 70m. (3) Compared to other conveying equipment, screw conveyors have advantages such as simple structure, small cross-sectional size, good sealing performance, the ability to load and unload at multiple points along the length, safe and convenient operation, and low manufacturing costs. Their disadvantages include severe wear of components, low conveying capacity, high power consumption, and the tendency for materials to break during transportation.
