VERFAHREN ZUR HERSTELLUNG VON ZEMENTKLINKER

摘要

Cement clinker may be prepd. from as-mined materials, which because of their high water content and other physical properties are unsuitable for dry processing, and for which filtration after wet processing is also unsuitable. The raw materials are not dressed to raw powder, sludge or filter cake before burning, but are mechanically reduced and homogenised from the as-received condition and then fired with the original moisture content or after pre-drying. Lower grade raw materials may be used. Less energy is required for firing than with wet processing.
