Solution Summary: Add-on Wet Dust Suppression Systems for Rock Crushers
Description:
National Environmental Service Company (NESCO) High Pressure Water Spray Systems
- Wet dust suppression systems can cost from $15,000, for small portable rock crushers, to $75,000, for large stationary aggregate plants. The average installed cost of a system for a typical stationary aggregate plant processing 1,000 tons per hour is between $40,000 and $50,000. Costs will vary significantly with the addition of accessories, such as compressed air and antifreeze systems and heat tracing spray lines.
- Used for dust control at crushing plants processing more than 500 tons per hour
- Pump pressure: 200 pounds per square inch
- Pump flow rate: 10, 20 or 40 gallons per minute
-
Standard Features:
- Pressure gauge and relief valve
- Remote control panel
- Brass plumbing

Risks Addressed:
Crushing rock and masonry material is a high dust activity that in the absence of controls would place workers at risk of lung disease, cancer, chronic obstructive pulmonary disease (COPD), lung scarring, silicosis, renal disease and autoimmune disorders, such as lupus and rheumatoid arthritis, with prolonged exposure. Silicosis is an incurable, sometimes fatal, disease. The NIOSH-recommended exposure limit is 0.05 mg/m3 as a time-weighted average concentration for up to a 10-hour workday during a 40-hour workweek. This is one-half of the OSHA standard when the dust is pure silica, but still twice the ACGIH-recommended threshold limit value of 0.025 mg/m3. Silica has also been associated with lung cancer and chronic obstructive pulmonary disease (COPD).
