SUBJECT: Fast Pack. Dust Suppression Purging Procedure
In some operation areas, the water in the dust
suppression hoses on the Fast Pack assembly
may freeze damaging the dust suppression system. Variables such as absolute temperature,
wind speed, and low flow are all contributing factors affecting freeze up. While it is difficult to
pinpoint the exact causes for freezing, KolbergPioneer, Inc. recommends that extreme care be
taken when using dust suppression when temperatures are below 32 degrees Fahrenheit. The
temperature inside the control trailer must be
maintained above 32 degrees Fahrenheit.
When the temperature is expected to drop
below 32 degrees Fahrenheit overnight, water
must be purged from the dust suppression hoses
to avoid freeze damage to components.
IMPORTANT
The following is a general procedure only. This
procedure may vary depending on the Fast Pack
configuration and components using dust suppression.
pressor turned on this will allow the main water
line to fill with air down to the AMS screen plant
(or the last core plant). When the drain is closed,
the water line will act as a reservoir for the air.
Starting at the plant closest to the control van,
turn on each ball valve to purge the water through
the nozzles. Close the valve when the line is completely purged. Finally, open the sub-main line
valves to purge the water through nozzles on the
off plant conveyors. Close the valve once purging is complete. Repeat this procedure for applying the glycol mist to the hoses. See drawing
on page 4 for more information.
Use the following procedure to drain the dust
suppression hoses.
1. On the touch screen, touch STOP to turn off
the dust suppression. In the control van,
make sure the air compressor is on.
General Purging Instructions
In purging the Fast Pack dust suppression
system, the operator purges the majority of water from the AMS screen plant, or the last core
plant from the control van. The manifold valves
on the main water line (1-1/2” hoses) must remain open while the ball valves (1” hoses) on
each component are closed. With the air com-

2. If equipped, turn off the valve to the filter
baghouse.
Air compressor regulator
should be set to 30 psi.

5. On each component along the main water
line, make sure all ball valves are turned off.
3. Make sure the air valve from the compressor is turned on. If it is off, turn it on.
6. On the AMS screen plant, or the last core
plant from the control van, open the drain
line. Once the water has purged, close the
drain line.

4. In the control van, turn off the water pump
feed line valve and turn on the air compressor purge line valve.
7. On each core plant, locate the ball valves.
On some plants these might be located
near the main manifold; on other plants
they may be located in different places.
Open each ball valve purging the water
through the nozzles until air begins to come
through. Close the valve.

12. Beginning again with the primary crushing
plant, open the main mainifold valve and the
plant’s ball valves to allow air combined
with a glycol mist to coat the hoses. When
the mist begins to exit the nozzles, close
the ball valve and move to the next valve.
Repeat this for all valves along the main
water line.

conveyors.
14. Turn off the valve from the air compressor.

9. Repeat this procedure for each component
along the main water line: screens, conveyors and crushers. Use the drawing on
page 4 as a guide (The main water line is
shown in red, water line for off plant conveyors is in blue)
10. After the main water line has been purged,
purge the water from the off plant conveyors.
11. Once the lines have been drained, go back
to the control van and open the glycol line
valve.
Glycol pressure gauge
should be set at 30 psi.
