Is the "Status Quo" Good Enough?
For many plants that make use of pneumatic conveying systems, maintaining the status quo seems sufficient. Many manufacturing plants have many years of service in them and many believe fully in the adage “if it aint broke, don’t fix it”. While it makes for a catchy slogan, when misapplied it can lead to stagnation and a gradual decline in quality and competitiveness over time. Because in many cases it actually is broken...but nobody has bothered to fret too much because there's been no good solution.
It's common to hear stories about blockages that cause unplanned downtime, quality problems with blending applications and wasted product during line restarts. Maintenance issues and product damage/loss are also common pain points.
The problem is that there's really never been an accurate way to measure actual particle speed. Calculations were made based on system parameters, and in some cases air/gas speed was measured. Those are substantially different than actual particle speed itself which will often determine which baked goods will crumble, which resin will smear and which products will create blockages.
To this end, many have seen the benefits of incorporating triboelectric monitoring systems into their dust collection and associated pneumatic conveying systems to improve operational efficiency, reduce costs and increase reliability. Let’s consider 2 areas that are commonly overlooked where a triboelectric system can provide real benefits.
