The speed of the screw axis has a great influence on the transportation quantity.. In general, rotating speed of the screw shaft speed, conveyor production capacity, speed is too small, the conveying amount decreased but the speed should not be too high because when the speed exceeds a certain limit value, the material because of centrifugal force outward
Throw, so unable to transport. So it is necessary to speed n for a certain limit, can not exceed a certain limit value. In order to ensure the material can be smoothly transported, and is not thrown, according to the experimental screw limit speed of
Type D spiral diameter, material characteristic coefficient check coefficient of material characteristics table can be obtained as raw materials 35.
Can D=0.1m into 1 type of screw speed from the above calculation
N=110 turn / points according to the screw conveyor speed series 20,30,35,45,60,75,90120150190 therefore circle the whole take the standard series value
N=120 / min
In this check fill factor
The recommended range of the fill factor meets the requirements
