The harmless fumes comes out in HMS during the melting process is to be safely collected and let out into atmospheric air outside the factory. We need to install three suction system to collect the fumes in three different points of HMS which has to be integrated and connected to a high power suction ID fan for the collection of fumes.
Such a way you can maintain clean ambience inside the factory premises for continues operation of plant into 24 x 7 period.
