Tubular screw conveyer is continuous conveyor equipment ，it uses  a rotating spiral to move materials。 It is suitable for transporting flour, grain, cement, chemical fertilizer, ash, sand and gravel, coal powder, small lump coal and other materials，as the effective flow area is small，It is not suitable for transporting perishable material, and the material with larger caking viscosity。Tubular screw conveyer is divided into the level and tilt of transmission, the customer should make a special order for other transportation.
      Screw conveyor is widely used in various industrial sectors, such as building materials, electric power, chemical industry, metallurgy, coal, aluminum, magnesium, machinery, light industry, food and food industry, it is suitable for horizontal or less than 20 ° tip angle. . Screw conveyor is with simple structure, low making cost, sealing strong, convenient unloading and operation, Remove the hanging bearing without moving screw,The machine has high reliability, long life, strong adaptability, easy installation and maintenance. It is not suitable for transporting perishable material, and the material with larger caking viscosity。These materials will be stuck on the spiral blade when transporting, so it can not move forward，the ematerial jam is occured in hanging bearing so it leads to  not work properly. The  diameter of screw has five kinds of specifications from 200 mm to 500 mm, the length is from 4 m to 70 m,every 0.5 meter is one grade, about special requirements ,the customer should inform the manufacturer when matching
