Determination of basic parameters of a screw
1) Screw rotation speed
300r/min is used in this example.
2) Outer diameter of screw
In the formula: dS- -outside diameter of screw
Q-output of straw fuel extrusion forming machine
β - -empirical factor, 0.005
Taking a standard value DS＝55mm
3) Length determination of each section of screw
Aspect ratio
Then L is 6DS＝6×55＝310mm
Length L of feed section1＝(10％-25％)L＝25％×310＝82.5mm
Length L of homogenizing segment2＝(50％-60％)L＝50％×310＝165mm
Length L of extruded section3＝(10％-25％)L＝25％×310＝82.5mm
4) Depth of screw groove
5) Lead I: the leading edges of one thread run axially a distance from the leading edge of the same thread after one revolution forward at their outer diameter. Because the machine adopts a screw with equal pitch and depth, the lead I is 30mm
