Using a Continuous Belt Filter in a Wet Process Cement Plant

The production of Portland cement requires that four basic elements – calcium, silica, alumina and iron be ground to a fine powder, homogenized, and fed to the pyroprocessing unit, where it is burned to a cement clinker. The raw material must either be ground wet in a slurry form or dried and ground to a dry powder, with a fineness of approximately 85% passing the 200 M screen. We then .
