Sectional Screw Flights
|
SINGLE FLIGHT STANDARD PITCH
Conveyor screw with pitch spacing equal to the diameter are considered standard and are suitable for most augers of conventional horizontal design.
|
DOUBLE FLIGHT STANDARD PITCH
Double pitch flights produce a smooth gentle flow, and assist in removing product from hoppers, or post hole digging.
|
SINGLE FLIGHT HALF PITCH
Half pitch conveyors are recommended for inclined or vertical conveying and for materials which are very free flowing.
|
|
FLIGHT RIBBON
Ribbon flights are excellent for sticky or gummy materials where the gap between the screw and the pipe prevent material build-up.
|
SINGLE FLIGHT VARIABLE PITCH
Flights with pitch progressively increased are used to draw fine, free flowing materials uniformly from the entire length of the feed opening.
|
The screw flight periphery is notched to supplement the conveying action with a moderate mixing action.
|
|
SINGLE TAPERED FLIGHT STANDARD PITCH
Tapering flight screw are generally recommended to draw lumpy materials from bins or hopers.
|
The paddle conveyor is made of steel paddles on threaded rod shanks inserted through the pipe. Conveying action can be controlled by adjusting the paddle angle. Excellent for stirring, blending or mixing dry or fluid materials.
