Installation and Management Of Side Draw
Systems in FCDL Series Bins/Silos
1.) Side discharge is only permitted in GSI stiffened
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 installa-
tion of additional wind rings and 3/4" diameter
anchor bolts. Reference the attached pages or
contact GSI. Installation of multiple systems
requires additional wind rings and must be placed
minimum of 90 degrees apart. Installation of
multiple systems requires approval of GSI.
3.) A side draw should not be the only discharge
system available. A standard center discharge and
conveyor should be installed.
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.
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grain is being withdrawn through the side draw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 consolida-
tion of foundation and fill soils and produce more
even settlement of the bin/silo.
5.) If geotechnical investigations or past experience
indicate significant foundation level soil variations or
a site propensity toward differential settlement, side
draw usage may be prohibited or severely re-
stricted. In this situation the use of a flume system
should be reviewed with geotechnical consultants
or the foundation engineer.
