How to diagnose and solve ducting problems in your dust collection system

Plants that handle bulk solids rely on dust collection systems not only to keep the workplace clean and healthy for workers, but to protect equipment and other valuable assets from fires and explosions. Yet more often than not, these dust collection systems underperform, leading to an unhealthy work environment, expensive ongoing maintenance, and premature equipment failure. This article explains how to diagnose problems with your dust collection system’s ducting system, a common trouble source. Sections explain how poor design, fabrication, and installation can lead to these problems and what you can do to remedy them.

Poorly performing dust collection systems are common in bulk solids handling plants. In fact, as many as 90 percent of the systems presently installed in US plants don’t perform up to expectations. Of these, up to 80 percent have performance problems associated with the ducting system, which includes the pickup hoods (also called capture hoods), dust containment enclosures (like chutes and belt conveyor skirting), and ducting. Unfortunately, these performance problems lead many plants to place unjustifiable blame on the dust collector itself.
