Triboelectric Monitoring Systems and the Cement Industry

Posted by Justin Dechene on Feb 8, 2017 10:45:00 AM

Cement is a building block industry of global progress.  Roads, buildings, bridges, factories, stadiums, airports and more - everywhere we go, and everything we do is built on cement.  And because it’s everywhere many take it for granted….but not all of us

In fact, we’re focused on the cement industry and Auburn’s triboelectric detection devices are used for many different functions in cement plants around the world.

Dust Detection

It’s a dusty business.  Period.  And environmental, pollution, emissions control and compliance requirements are tough.  That demands not only effective cement dust collection systems, but also effective monitoring.  Triboelectric bag leak detection systems built on unified (DC & AC) digital signal processing are engineered for use in standard and hazardous locations, and provide more than simple compliance monitoring. 

Certain triboelectric sensors can monitor not only absolute levels of particulate emissions, but trends.  And with that capability they provide predictive maintenance information and early warning.  Dust events can be prevented and deteriorating bags often replaced BEFORE they break.  These capabilities make dust control in the cement industry a function companies can proactively manage rather than one to which they must respond


Fugitive Ambient Dust Monitoring

In addition to optimizing the kiln and controlling emissions, cement plants must monitor fugitive dust to reduce risk of explosion and ensure package integrity.

It’s a dirty, dusty business, and even locations with strong safety programs can experience explosive buildup (just as a cement plant in Boston did in 2006.)  Therefore it’s important to have easy, reliable fugitive dust control in a cement plant - and consistent monitoring. With increased emphasis on the dangers of silica in the work place, ambient fugitive dust monitors can provide a solution.

Ease Regulatory Burden

The installation of triboelectric dust and monitoring equipment solved two tough monitoring problems for this major cement manufacturer. Previously, dust monitoring rules required daily visual inspection of each dust collector for 6 minutes (Method 22) and if dust was detected, followed by another visual inspection (Method 9, which can only be performed by certified "smoke readers"). The operators successfully eliminated Method 22, freeing up about 2 hours of manpower a day. If the monitors detect a leak, the plant must perform corrective action within 24 hours.
