Tubular screw conveyor is widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal mine charcoal, food and other industries, suitable for horizontal or inclined transport of powdery, granular and small block materials, such as coal mine, ash, slag, cement, food, etc., the material temperature is less than 200℃.Tubular screw conveyor is not suitable for conveying perishable, viscous, easy to agglomerate materials.Concrete mixing plant, the role of the screw conveyor has been reflected.
1.The ambient temperature of screw conveyor is -20 ~50℃;Inclination Angle of conveyor beta ≤20°;The conveying length is generally less than 40m and less than 70m.
2.Compared with other conveying equipment, spiral conveying has the advantages of simple structure, small cross section size, good sealing performance, intermediate multi-point loading and unloading, convenient operation and low manufacturing cost.Its disadvantages are more serious wear and tear parts, lower throughput, large consumption of power and materials in the transport process is easy to be broken.
3. screw conveyor is widely used in the chemical industry, building materials, food and other departments of a conveying equipment, mainly used for conveying powder, particle and small block materials.It is not suitable for transporting perishable, viscous and caking materials.
Tubular screw conveyor generally consists of three parts: the conveyor body, the inlet and outlet, and the drive device.Screw conveyor of the screw blade entity helicoid, belt type spiral blades of screw surface and surface three forms, among them, the spiral vane surface application is relatively small, it is mainly used for transporting materials in large viscosity and compressibility of the screw surface type, in complete conveying operation process, at the same time with and complete mixing, mixing of materials, and other functions.The characteristics of tubular screw conveyor are: simple structure, small cross section size, good sealing, reliable work, low manufacturing cost, convenient for intermediate loading and unloading, the direction of transport can be reversed, but also to the opposite direction of two directions.It can also stir, mix, heat and cool the materials during transportation.The material flow can be adjusted through the loading and unloading gate.But should not transport perishable, viscous, easy to agglomerate and bulk materials.The material is easy to be broken and the spiral and trough are easy to wear.Larger unit power.In use to maintain the sealing of the trough and the appropriate gap between the screw and the trough.
Compared with other conveying equipment, tubular screw conveyor has the advantages of small cross section size, good sealing performance, stable and reliable operation, middle multi-point loading and unloading, simple operation and maintenance, etc.Tubular screw conveyor is not suitable to transport perishable, viscous, easy to agglomerate materials, because these materials will be bonded to the screw in the transmission, and then rotate and do not move forward or in the bearing to form a material accumulation plug, so that the screw machine can not work normally.LS type screw machine screw diameter from 200 mm to 500 mm, a total of five specifications, length from 4 m to 70 m, every 0.5 m a gear, when the selection of standard nominal length, special needs can be separately put forward in the selection section.
