Product Introduction

　　The shaftless screw conveyor is like a rotating screw shaft that drives a nut to move along its axial direction.The screw body is equivalent to the screw shaft,and the material is equivalent to the nut.When the screw body rotates continuously,the material is also transported continuously.The spiral body of the shaftless screw conveyor is a thick belt shaped blade,which is driven by the driving end shaft.There is no shaft in the middle,and the spiral body contacts the bottom lining plate of the inner wall of the casing.

　　Product Usage

　　Spiral conveyors have the advantages of simple structure,low manufacturing cost,strong sealing,safe and convenient operation,and can be loaded and unloaded at multiple points in the middle Widely used in chemical,building materials,metallurgy,grain and other sectors,it can transport powdery,granular and small pieces of materials with low viscosity and low susceptibility to deterioration at an inclination angleβ<20°Compared with traditional screw conveyors with shafts,shaftless screw conveyors have the following outstanding advantages due to the adoption of a centerless shaft design and the use of a flexible integral steel screw to push materials:strong resistance to entanglement.
