The majority of material in the silo free flows, first through the discharge opening in the floor center and
secondly through the discharge wells on top of the reclaim tunnel. When free flow stops, the Weaver Bin
Sweep with its center drive will automatically sweep the grain on both sides of the reclaim tunnel into the
center discharge as it rotates around the floor of the silo. Its powerful, compact and efficient design, with
high capacity, will obtain maximum emptying of the silo with one or two passes. No personnel entry, health
hazards, equipment modifications, or belts, bearings, motors, steel/rubber carrier drive wheels, etc. are
needed inside the silo. That’s right! It’s all done automatically.

Reclaimers have
low power requirements.
The electric drive motor
on the discharge auger
unloads almost the entire
silo. Mill capacity and
discharge auger volume
are easily matched for
smooth operation and
performance. An access
door to the parking
garage is located in the
silo wall, through which
the parking garage can
be easily removed for
reclaiming the material in the bottom of the
silo. The parking garage
can be removed without interfering with any
equipment in the control
room. In addition, the
location of the silo access
door outside the control
room can be used for
side drawing materials
for surplus sales. Our
silo access door design
allows you to release the
sweep auger for 18” of
travel before making a
full commitment to a
360 degree sweep for
final clean out of the silo.
