Abstract

The invention relates to a method and a device for grinding moist material in a vertical roller mill and is in particular suitable for the cement industry and the grinding of moist cement raw material and cement clinker and moist additional materials. In order to prevent adverse reactions between moist materials or between moist and dry materials in particular in the production of cement mixtures and in order to achieve an optimization of the grinding and sifting process an improved energy efficiency and the maintenance of the desired product quality and mill throughput a predrying of the moist material is provided in a predrying device integrated into the roller mill. The predried material passes via the reject circuit and the sifter where the fine material is separated for the first time into the grinding chamber and is supplied to the grinding stage. Direct current tubular dryers are preferably incorporated as integrated predrying devices into the vertical roller mill and extend from at least one charging device in the upper mill region up to virtually an annular gas outlet opening for a hot gas stream said gas outlet opening surrounding the grinding bowl.
