Tubular screw conveyor is the use of helical rotation and the passage of continuous material conveying equipment, pipe conveyors suitable for transporting flour, grains, cement, fertilizer, ash, sand, gravel, coal, small lump coal and other materials. Due to the small effective flow area of ??the body, pipe conveyors should not lose pounds perishable, too viscous, easy caking materials. Tubular screw conveyor may be arranged to form a horizontal or inclined conveyor, screw conveyor pipe To change to the delivery, should make a special order. Applications :: screw conveyor screw conveyor is widely used in various industrial sectors such as building materials, electricity, chemical, metallurgy, coal, aluminum and magnesium, machinery, light industry, food and food industries; for horizontal, inclined or vertical transport, conveying powder, granular and small block materials, such as cement, coal, grain, fertilizer, ash, sand, etc., the following material temperature 200 ℃. Not screw conveyor transport perishable viscous, easy caking materials, because these materials at the time of delivery will be bonded to the spiral, and rotates without moving forward or volume of materials formed at the hanging bearing plug, leaving the screw machine is not working properly. Screw Conveyor Category: Screw diameters from 200 mm to 500 mm, a total of five sizes, length from 4 m to 70 m, at intervals of 0.5 m of a file, when the selection standard nominal length, special needs can be when matching type presented separately. Tubular screw conveyor rotating helical blade will be the passage of a screw conveyor transporting material, so that the material is not rotated together with the screw conveyor blade force is the material of its own weight and friction of the material the screw conveyor housing. Welding rotating shaft helical screw conveyor blade, blade face type depending on the transport of materials have a physical face, a belt face, the blade surface type and other types. Screw conveyor screw axis in the direction of material movement terminal has thrust bearings with the material to spiral axial reaction force, the longer the captain, should be added to the intermediate hanger bearings.
