2PGC double tooth roller crusher structure diagram
Specifications
LS, GX type screw conveyor specifications and technical parameters see the table below, length from 3.5m to 80m, standard interval 0.5m first gear, drive device is divided into two kinds, C1 method -- screw conveyor length is less than 35m single end drive, C2 method -- screw conveyor length is greater than 35m double end drive.
Considerations for selection:
A. Spiral diameter
The minimum spiral diameter shall be determined by the rotating speed and the conveying capacity, and meet the following conditions: for conveying bulk materials, the spiral diameter D shall be at least 10 times the maximum side length of particles. If the content of large particles is small, a smaller spiral diameter can be selected, but at least 4 times the maximum side length of particles.
B, rotational speed
The speed of screw conveyor is not allowed to be too large, otherwise the material is transported by strong centrifugal force, so that the conveying process is affected, according to JB/T7679-95 "Screw conveyor" standard each specification has 4 kinds of speed for selection.
