4. Find the point at which these two values meet on
the table (see example below). This box shows
the Optimal Flow Rate for this liquid application
(0.74 gal/min).
5. To achieve the desired liquid rate in this example,
you would adjust the system to 0.74 gal/min. For
details, refer to "Adjusting the Flow" on page 15.
Material Application Example:
A HELIXX™ hopper spreader is running at auger
speed 7. The desired liquid rate is 8 gallons per ton.
Use the following procedure to determine the optimal
fl
ow rate in gal/min.
1. On the Application Rate chart on page 16,
fi
nd
the point on the graph where the 7 on the Auger
Speed axis and the line intersect.
2. Follow from the point of intersection across to
the Auger Flow Rate axis, as shown below. The
delivery
fl
ow rate for this example is 2.5 ft³/min.
3. On the Optimal Flow Rate table on page 17,
fi
nd the Delivery Flow Rate value (previously
determined in Step 2 (2.5 ft³/min) and the
Application Rate (8 gal/ton).
