Tubular screw conveyor main components with the use of the characteristics of the tube screw conveyor device has been widely used in powder and granular material transport; the pipe conveyor using carbon steel, suitable surface finishing, the main components include : At least with the inlet and outlet of the tubular tank, welded pipe flange both ends of the spiral blades welded on the central tube coupling bush leaves both ends, with two self-adjusting shaft sealing unit end bearing assembly, the overall length of the middle number is determined by a screw conveyor hanger bearings; In addition, to meet user requirements, can be equipped with gear motors. Rotating helical screw conveyor is the use of the material along the continuous passage of the housing is conveyed, and is an important job cement silo transportation equipment. The machine has a simple structure, small size, low cost, safe operation, according to process requirements can meet the multi-point feeding and nesting. Screw machine is widely used in various industries, such as building materials, chemicals, power, metallurgy, coal carbon, food and other industries, for horizontal or inclined conveying powder, granular and small block materials, such as coal, ash, slag, cement, food and so on, the material temperature is less than 200 ℃. In concrete mixing station, the role of screw conveyor has been the greatest expression. Tubular screw conveyor application features: 1, standard parts assembly, transportation convenience. 2, the adequate spare parts, complete specifications. 3, screw machine adopts high-quality steel, the overall rigidity. 4, optional universal ball to make installation easy to adjust the steering. 5. Double pitch blades, reducing material handling is the degree of compression. 6, forming a helical blade, double pitch design, never blocking material. 7, with a good quality of bearing and rear bearing hanging, and easy to install. 8, using high-quality gear box, heavy duty design, with torque, low noise characteristics. 9, used a lot of stocking 168,219,273,325,402 diameter, size and angle can be customized according to customer requirements.
