Making blasting technology efficient – a decisive cost factor
The coordination of air pressure, air volume (CFM), media feed, and nozzle size significantly influences productivity and abrasive consumption in the blasting process. An optimal setup saves time, reduces costs, and improves blasting results.
What makes an efficient setup?
For a blasting system to work efficiently, the abrasive-laden air mixture must hit the surface with maximum kinetic energy. The higher the energy, the faster the blasting process with lower material usage. (elcometer.com)
Elcometer practical knowledge: key variables
- Air pressure & air volume: High pressure + high airflow deliver more kinetic energy → more efficient blasting. (elcometer.com)
- Adjusting media valves: Too little abrasive reduces speed, too much slows airflow – the goal is the optimal balance. (elcometer.com)
- Selecting nozzle size: Larger nozzles enable higher coverage at high pressure, but only with sufficient air volume. (elcometer.com)
Practical tip:
Start with medium air pressure and volume, adjust the media valve gradually, and change nozzle size step-by-step. Measure blasting progress and abrasive usage – the goal: maximum surface area with minimal consumption.
