What advice can you give us to improve the material discharge from our storage vessel?

What’s the most efficient mechanical conveying method for a cohesive material?

Our company has used bag- and cartridge-type dust collectors for years, but they’re no longer doing the job we need effectively. Is there an alternative you could recommend?

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?

Electrostatic sparks cause many industrial fires and explosions every year. What advice can you offer on what to look for to avoid electrostatic sparks in our plant?

We’re having trouble optimizing and stabilizing our hammermill’s performance. Do you have any suggestions?

We plan to retrofit our pneumatic conveying system soon. How can we ensure that our system’s line routing best avoids plant obstacles?

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?

I work for a major bakery and one of my responsibilities is to ensure that we comply with the NFPA combustible dust standards. It appears we must comply with both NFPA 652 and 61. Is this correct?

Our facility handles a low-melting-point sugar in our process. Are a material’s properties really all that important in pneumatic conveying?

Our plant’s dust collection system experiences consistent buildup inside the ducts and in other areas. How can we avoid plugging so our system operates smoothly?

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?

We want to improve our hopper design. How can we use angle of slide, angle of repose, and internal angle of friction to improve our hopper?

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?

What’s an unstable pneumatic conveying zone, and how do we overcome one?

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?

How can we avoid material flow problems that might result from a poorly designed storage vessel?
