Selecting the Appropriate “Series” Grain Bin
Grain storage tanks are offered in more than one structural series for specific uses. In order to maintain
the 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
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
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. Run the unit one complete revolution after about 3' of grain has been put into the bin, to see that the
unit is operating correctly.
4. 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 with laterally moving screws, attempt 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 inoperative for any length of time, the auger carriage should be
supported to the grain surface before re-starting. 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 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 general instructions which apply to the major types of stirring devices. Since
there are several different manufacturers, it is important that you read the operator’s manual
thoroughly for specific instructions applicable to the machine.
WARNING
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 bin wall can be
overloaded. Observe the following installation and operation procedures if the bin
is to be equipped with a stirring device.
