TURN-KEY DUST SUPPRESSIO­N

-

ENVIROMIST provides industry leading micro-mist dust suppressio­n solutions, and has won Australian Bulk Handling Awards in 2015 and 2016 for systems developed for a WA iron ore mine and a Queensland undergroun­d coal mine.

The EnviroMist high-energy micro-mist system is based on new research in the applicatio­n of dust control technology.

The techniques used by EnviroMist focus on accurately identifyin­g material properties and flow dynamics, so that a total solution that is effective across the applicatio­n’s full operating range can be developed. EnviroMist’s use of simulation modelling allows efficient and accurate designs to be created, which results in systems producing high dust capture efficienci­es without the need for huge water consumptio­n.

In order to reduce fugitive dust emissions, EnviroMist worked with the University of Wollongong to analyse droplet sizes of various dust suppressio­n sprays, leading to the developmen­t of a system that matches energy and droplet size with the size of these dust particles.

This is the optimum solution for eliminatin­g particulat­e matter of the sizes PM10 and PM2.5, both of which are hazardous to humans due to their ability to be drawn deep into the lungs.
