2-meter Mini Tubular Screw Feeder with Excellent Powder Conveying Quality

The 2-meter micro tubular feeding screw conveyor excels in powder material transportation quality, Application Scope and Features:(1) Hebei screw conveyor is a widely used conveying equipment in chemical, building materials, grain, and other sectors, mainly for transporting powdered, granular, and small lump materials. It is not suitable for conveying perishable, sticky, and easily agglomerated materials. (2) The operating environmental temperature for screw conveyors is —20~50℃ ; the conveyor's inclination angle β≤20°; the conveying length is generally less than 40m, with a maximum not exceeding 70m. (3) Compared to other conveying equipment, screw conveyors have advantages such as simple structure, small cross-sectional dimensions, 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 on components, lower conveying capacity, high power consumption, and the tendency for materials to break during transportation.

Classification and Structural Features:(1) The screw blades of screw conveyors come in three types: solid spiral surface type, belt spiral surface type, and blade spiral surface type. The solid spiral surface is called the S method, with its screw pitch being 0.8 times the blade diameter for the GX type, and the LS type screw conveyor is suitable for conveying powdered and granular materials. The belt spiral surface, also known as the D method, has a screw pitch equal to the screw blade diameter and is suitable for conveying powdered and small lump materials. The blade spiral surface is less commonly used, mainly for conveying highly viscous and compressible materials, and it can simultaneously complete processes like mixing and blending during transportation, with a screw pitch approximately 1.2 times the blade diameter. (2) The screw blades of screw conveyors come in two rotational directions: left-hand and right-hand.The 2-meter micro tubular feeding screw conveyor excels in powder material transportation quality.
