Installation and Management
Of Side Draw Systems
Grain Systems designs and manufacturers bins to the highest standards, however proper installation and good
usage practices for a commercial flume system are essential, regardless of manufacturer . The following practices
address general usage and installation criteria for such systems.
SIDE DRAW INST ALLA TION SIDE DRAW MANAGEMENT AND USAGE
1.) Side discharge is only permitted in GSI
commercial bins when a GSI manufactured side
draw flume system has been installed. No
corrugated steel bin should be unloaded through
the sidewall without installation of such a system
and permission of the manufacturer.
2.) Installation of a flume system may require
installation of additional wind rings and 3/4"
diameter anchor bolts. Reference the tank gauge
sheet for wind ring placement or contact GSI.
Reference the attached page on 1" anchor bolt
usage.
Installation of multiple systems may require
additional wind rings and must be placed a
minimum of 90° apart. Installation of multiple
systems requires approval of GSI.
3.) A side draw should not be the only discharge
system available. A standard center discharg e
and conveyor should be installed.
1.) Side draw systems are intended for use with dry
flowable grain. Side draws are not to be used for
poorly flowing products. This is not unique to GSI
bins and flume systems but is a general rule for such
systems.
2.) In multiple system installations only one side draw
may be used at any one time.
3.) Filling should not be occurring at the same time as
grain is being withdrawn through the side draw
flume system.
4.) Prolonged storage of grain in the sloped condition
produced by side draw discharge may accelerate
differential settlement and result in deformations of
the bin/silo. After using the side draw system the
sloped grain should be returned to a near level
condition by use of the center discharge. Leveling
of the grain should also allow more even consolidation of foundation and fill soils and produce more
even settlement of the bin/silo.
5.) If geotechnical investigations or past experience
indicate significant foundation soil level variations or
a site propensity toward differential settlement, side
draw usage may be prohibited or severely restricted. In this situation the use of a flume system
should be reviewed with geotechnical consultants
or the foundation engineer.
