START-UP DUST CONTROL SYSTEMS
1. Fan or blower system
A. Start the fan or blower and check rotation.
B. Check dust pickup points for proper suction; balance airflow in individual
ducts.
C. Check for air leakage at all flanged connections.
2. Equipment start-up sequence
A. Start the pulse arm drive motor (direction of rotation is not critical).
B. Start the PD pump motor and check rotation.
C. Adjust timer Off-time by watching pressure gauge on PD pump. The
pressure in the tank should peak between 7-8 PSI. Increase or Decrease time
to obtain the correct pressure. Note: Verify the Weighted relief valve in the
clean air plenum is not activating – decrease Off-time if it is bleeding air.
D. Dust take away equipment such as rotary airlocks, screw conveyors,
horizontal unloading valves, live bottom bin activators, and pneumatic
conveying systems can now be started in their correct sequence.
E. Check that all access doors, hatches, ports, and other openings are closed and
latched or bolted.
F. The main exhaust fan can now be started and brought up to speed.
G. Start the dust laden air through the collector. The collector should be started
under partial load to allow the bags to become slowly and evenly coated with
dust particles.
On pneumatic conveying systems, watch the differential pressure gauge
closely for the first hour or so. If unstable, the collector discharge system
may be too small for the volume it is seeing. A quick fix is to reduce the
material feed until the discharge rate can be increased.
