Bins with Stirring Devices
Selecting the Appropriate “Series” Grain Bin
Grain storage tanks 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 systems should be used in the “re-circulating” series bins. Re-circulating devices include
products such as the grain flow, foreway, shivers units or similar devices.
General Instructions for Stirring Devices
Bins are offered in more than one structural series for specific uses. In order to maintain warranty, the
appropriate “series” grain bin must be used. Consult the sales catalog or contact the engineering
department for current recommendations. Especially note that 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: Additional loads on grain bin sidewalls, roofs and floors can be created by stirring devices. If
high-moisture grain is loaded too deep and too fast, any unstiffened bin wall can be overloaded.
Observe the following installation and operation procedures if the bin is to be equipped with the
stirring device.
1. Read the 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 three feet (3') of grain, run the unit for 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 the 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 the 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 the bottom of the 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.
WARNING
Stirring devices may create additional loads on grain bin sidewalls, roofs and
floors. If high-moisture grain is loaded too deep and too fast, bin walls can
become overloaded. Observe the following installation and operation procedures
if the bin is to be equipped with a stirring device.
