Screw conveyor according to the conveying form is divided into shaft screw conveyor and shaftless screw conveyor. According to the appearance, it is divided into U shape screw conveyor and tube type screw conveyor. Shaft screw conveyor is suitable for the non-sticky powder material and small particle material such as cement, fly ash, lime, food, etc. Shaftless screw conveyor is suitable for conveying sticky and easy-winding materials such as sludge, biomass, litter, fibers, etc.
Conveying Distance
≤30m
Conveying Capacity
100m³/h
Application Industry
uitable for various industries such as building materials, chemical industry, electric power, metallurgy, coal mining and food etc..
Applicable Materials
Applicable for conveying powder, granules and small lump materials block in horizontal or oblique such as cement, fly ash, pesticides, titanium dioxide, paint, etc..The material temperature is less than 200 ℃. Screw conveyor is not suitable for transportation of perishable, high viscosity, or easy to agglomerate materials.

Working Principle
When the screw shaft is rotating, due to the gravity of the material and the friction between the materials and the wall, it makes the material moving forward along the conveyor bottom under the push of the blade. It looks like an un-rotatable nut does translational movement along the rotating screw. The materials movement at the mid bearing is pushed by the moving-forward materials from back. Therefore, the materials delivery inside the conveyor is like a kind of slip movement. To have the screw shaft under better pulled state, normally have the motor and discharging port at same side of the screw conveyor. And have the outlet at the other end of screw. The screw blade push the materials to realize materials-delivery. Because of the materials gravity and also the friction between the materials and shell, the materials will not rotate together with the screw. The screw blade surface type according to the to-be-conveyed materials, it can be: entity type, belt type, and leaf surface type. The screw shaft of the Screw Conveyor is with thrust bearing at the end of the materials moving direction to give the screw shaft reverse force together with the materials. When it is comparatively long, then mid hanging bearing is required.
