Method and installation for comminuting or milling moist materials and their drying in a hot gas flow

摘要

In order to comminute and dry moist materials, e.g. moist cement raw material, for the purpose of feeding into a cement clinker production line, in such a manner that the expenditure on apparatus and operation for the comminution or milling and drying is very low, it is proposed according to the invention that the moist cement raw material (10) is subjected to a material bed comminution in the roller gap of a high-pressure roller press (11), with agglomerates (scabs) being formed, and that the moist scabs (13) are if appropriate deagglomerated in a sifter (14) which is operated by the hot exhaust gas flow of the cement clinker production line and is necessary in any case for the cement raw meal manufacture, and the deagglomerated material is dried and sifted in the same sifter. <IMAGE>
