Process, Resource Impacts

False Air Inspection Instead of leaking out from within the process, there is now a problem with ambient air being sucked into the system, called false air. Depending on the point of entry, false air has different undesired effects. That is why a lot of effort is made to keep process systems tight. Main Impacts of False Air

FALSE AIR INFILTRATION • Coal mill intensive bag filter gas analyzer oxygen concentration must be less than 10% in order to avoid any accident and also for efficient mill operation. • If oxygen concentration at Intensive bag filter is high then do mill audit for the identification & rectification of false air infiltration points.

Cement mill - Wikipedia

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
