Wet suppression is used for fugitive dust control of the tertiary crusher. There are water spray nozzles loed at the discharge point of the inlet conveyor, midway
“Fugitive dust” is a term used to describe any particulate matter (PM) emissions released through any means other than a stack or duct of some kind.
Dust emissions in quarries come from multiple point, surface and linear emissions sources Material processing: crushing, screening and transfer points .
Foam suppression, however, is often the preferred option on a crushing plant ( and also reduces dust emission when the aggregate is subsequently offloaded).
