Cement Plants

Multiple applications for triboelectric detection in cement plants

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 collection

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 (AC & DC) 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.


Pulverized coal injection

Making great cement requires consistent, precise processes.  And accurately monitoring and controlling the pulverized coal injection into large scale kilns is critical to that consistency.

Unstable flame, varying ignition point, risk of flame out and even potential explosion risk are common concerns related to inconsistent fuel delivery.  Additionally suboptimal fuel/air feed ends up creating excessive CO, SOx and NOx emissions...not to mention increasing carbon content in the clinker.

The good news is that there’s an efficient solution to optimize kiln operation for reduced emissions and product quality control.  And it’s essentially the same technology that is used in other flow control monitoring applications such as replacing impact flow meters for better measure of material flow through a reject air slide from the high efficiency seperator.

Controlling fugitive dust

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

It’s a dirty, dusty business, and even locations with strong safety programs can experience dust buildup that can be harmful to employee health. 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.
