Cement is a powdered substance made primarily of burned lime, clay, and fly ash. Cement manufacturing involves
many processes including mining, crushing, screening, recovery, calcining, finishing, grinding, conveying and
shipping. Particulates can be emitted from any of these steps. Facilities can also operate on a variety of fuels
requiring additional air pollution control. This course covers the production processes of cement manufacture with
corresponding air pollution control issues. There will be a field visit in the afternoon. Participants must bring their
hard hats, safety shoes, hearing and eye protection. SITE VISIT RECOMMENDED.
