We’re having trouble with our dust collector that separates milled material from our pneumatic conveying airflow. We’ve needed to replace the filters every 4 to 8 weeks, and the material doesn’t reliably discharge from the dust collector. Do you have any suggestions to help us?
Our new batch uses the same composition and is supposed to match our first batch, but the onset of bubbling when the material is fluidized occurs at higher superficial gas (or air) velocities than with the previous batch. What could be causing this difference?
Six months ago we bought a centralized vacuum cleaning system (CVCS). The system worked great when it was new, but lately the system has been plugging frequently and doesn’t perform well. Our CVCS is designed for three simultaneous operators with a 2-inch-diameter, 25-foot-long hose for each connection station. What could be wrong?
Our plant has experienced canopy hood issues causing dust collection failure and ongoing filter media plugging. Can you share some examples of dust collector problem solving you’ve done related to these two issues?
My facility is a food processing plant, and I know I have a relatively short time to complete my dust hazards analysis (DHA). However, I’m confused and frustrated by the need to have so many NFPA standards to accomplish the required DHA. Can you give me some advice?
We just completed our DHA and were told our dust collection systems don’t work properly. In fact, the dust collection systems have been deemed a combustible dust hazard because of poor design, especially the hoods. Why is hood design so important?
