1,Screw conveyor is a powdered material handling device, and its structure is simple and compact structure, reliable performance and low cost,which is widely used in food industry, building materials industry, chemical industry, transportation and other departments, such as the transportation of cement, chemicals, sand, flour, salts etc.
2,The selection of screw conveyor
(1)the selection of screw conveyor, first of all in the material for screw conveyor under the premise, users according to the design parameters submitted single provide parameters and site layout to determine the specifications of models of screw conveyor, position and length.
(2)for the larger proportion of the conveying materials of concrete mixing station screw conveyor, the angle should not be greater than 50 degrees, otherwise the transmission efficiency is greatly reduced.
(3)the minimum screw diameter of the screw conveyor depends on the required yield and the size of the bulk particle size.
For the transmission block material:
unsorted material: D ≥(8~10)d d= material average block size (mm)
sorting material: D≥(4~6)dm dm=maximum block size of the material(mm)
