Velocity Chart
To be used in layout and selection
of velocity reduction equipment.
This chart is a guideline for spouting corn, soybeans or wheat in round steel spouting. You should run spouts
in the green area. The yellow area requires ow retarders. The red area is too at to ow.
Velocity can be reduced by lowering angle of spout. In 90° spouts, a ow retarder is recommended every
12 feet. In 60° spouts, a ow retarder is recommended every 25 feet. In 45° spouts, a ow retarder is
recommended every 40 feet. In 35° spouts, a ow retarder is recommended every 95 feet.
PREFERRED SPOUTING RUNS. By dropping vertical and installing vertical ow retarders and vertical drop
turnout, you can often eliminate inline ow retarders. The reduction of velocity protects and helps maintain
quality of product being handled and reduces wear on spouting and accessories.
Green area represents
spout that does not require
Inline Flow Retarders.
***Urethane lined spouting requires 38 degrees or greater. UHMW lined spouting will increase velocity. Wet corn or ground feed ingredients will not ow
at 35 degrees. Feed pellets have varying ow rates. Flow retarders help maintain quality of feed pellets. Chart information is for guidelines only -- actual
results will vary.
