screw conveyor has a simple structure, making low-cost, sealing strong, safe and convenient operation, etc., in the middle of multi-point loading and unloading. widely used in chemical industry, building materials, metallurgy, food and other departments in the inclination angle β <20 °the case, the viscosity of conveying small, non-perishable, not locust caking powder, granular and small pieces of material. shaft screw conveyor traditional shaft screw and belt conveyors is not possible or difficult to transport materials such as granular and powdered materials. wet and pasty materials. semifluid and viscous materials. easy winding and easy to plugmaterials. shaftless screw conveyor special health requirements of the material. shaftless screw conveyor performance characteristics: shaftless screw conveyor and tradition have shaft screw compared to no center shaft design, the use of certainoverall flexible steel spiral push the material, and thus has the following outstanding advantages: good environmental performance compared with a shaft screw conveyor, weight and cost will reduce a lot. concern: pam / pac dosing device
