Assessment of Air Pollutants Emissions from a Cement Plant ...

clinker, and (3) the cement mills. Dust [which includes (Total Suspended Particulates (TSP), Particulate Matter smaller that 10µm (PM10) and Particulate Matter smaller than 2.5 µm (PM2.5)], SO2, NOx and CO are expected to exit from the raw mill and kiln stack. Dust is the only expected emission from the cooler stack and the cement mills stack.

01/12/2012  In cement plants, fugitive emissions of raw materials and cement dust may be appreciable and can cause ill health by skin contact, eye contact, or inhalation. Risk of injury depends on duration and level of exposure and individual sensitivity. Cement may contain hazardous substances like crystalline silica (quartz), lime, gypsum, nickel, cobalt, and chromium compounds

Dealing with dust - International Cement Review

The simple question of what to do with baghouse dust when the raw mill is out of operation has plagued the cement industry since the invention of the rotary kiln. In wet kilns the dry dust was difficult to mix back in as it impacted the slurry characteristics. New inventions such as dust insufflation and mid-kiln dust scoops were developed to manage the problem. In long dry kilns dust was less ...
