Instructions for Stirring Devices
Bins are offered in more than one structural series for specific uses. To maintain the warranty, the
appropriate “series” grain bin must be used. Consult the sales catalog or contact the Engineering
Department for current recommendations. Note that the use of any stirring device with three (3) or more
vertical screws may require a heavier than “standard” series bin. Any re-circulating device or system
should be used in the “re-circulating” series bins. NOTE: For GSI bins larger than 33' diameter an
alternate method of mounting is to attach suspension chain to intermediate center collar.
1. Read owner’s manual for the stirring device and follow all instructions set forth by the manufacturer.
IMPORTANT: Install the switch for the stirring device near the roof manway opening so that the
unit can be observed while stirring.
2. Make sure there are no obstructions, such as protruding ladders.
3. After loading approximately 3' of grain, run the unit one complete revolution to determine if it is
working properly.
4. If the unit is functioning properly, operate the stirring device continuously while filling and drying to
avoid compacted grain around the vertical screws.
5. If it becomes necessary to stop a stirring device using laterally moving screws, try to stop it with the
vertical screws nearest to the center of the bin, away from the sidewall. Should a device stop or stall
for any reason and remain inoperable for any length of time, the auger carriage should be supported
to the grain surface before restarting. The vertical auger should be turned by hand, with a pipe
wrench, before power is applied.
6. For best results, fill the bin to one-half of the final intended depth. Dry grain to 16% and continue
filling. Use filling rates specified by stirring device manufacturer. If necessary to fill to the top without
stopping, reduce the filling rate and drying air temperature so that the stirring rate can keep up with
the drying rate.
7. Do not overfill bin. Filling should be stopped at bottom of top ring or 30" below the track.
8. The preceding steps are only general instructions which apply to the majority of stirring devices.
Since there are different manufacturers of these devices, it is important to read the operator’s manual
thoroughly for specific instructions applicable to the machine.
Stirring devices may create additional loads on grain bin sidewalls, roofs and
floors. If high-moisture grain is loaded too deep and too fast, unstiffened bin
walls can become overloaded. Observe the following installation and operation
procedures if the bin is to be equipped with the stirring device.
