Dust
Collection System Evaluation
Purpose
- To determine the operating efficiency of all aspects
of a dust
collection system
- To identify capture containment, conveyance and filtration
limitations
- To make specific recommendations for improvement
in the operation and
maintenance of the system
Procedure
- Determine exhaust stream total volume and duct static pressures
- Measure duct velocities in all locations to ensure conveyance
velocity
maintenance
- Measure enclosure / capture hood in-draft velocities and evaluate
for
dust containment / control
- Evaluate filter unit design and application, check
filter reconditioning
system operation
- Inspect material discharge device
- Evaluate exhaust fan characteristic
curve / system curve intersection
point
Report
- Provide a written report outlining system operational status,
identifying design and operating deficiencies
- Provide a schematic
duct diagram illustrating exhaust volumes,
velocities and static pressures in all parts of the system
- Provide
specific recommendations for improvement
