General indications
for efficient operation
Sweep auger efficiency is dependent on the type of grain being unloaded. The highest output measured in tons
extracted per hour is obtained with grains that run well. Free running grain results in more efficient auger
operation, a higher discharge rate and less stress on mechanical components.
The opposite is true of grain that does not run so well, that clusters together because of contamination with straw
or twigs, excessive moisture, or because grain shape lends itself to interlocking. In these less than ideal
conditions, work speed
is necessarily compromised.
The following drawings depict magnitudes A, B, C & D. The text that follows can help you assess how
these parameters interact with each other and with different grains to help optimize operation:
“A” is the height that grain within the bag can be taken to by increasing or reducing the pickup roller's RPM's. This
level must not exceed the roller's height to prevent grain from being picked up with the plastic sheet. With this
constraint, grain level should normally be maintained as high as possible so that, with the aid of gravity, it can
readily fall back onto the sweep augers and be directed to the discharge auger.
