Document Type and Number:
WIPO Patent Application WO1999054044
Kind Code:
B1
Abstract:
The invention relates to a method and corresponding device for the fine grinding of solid mineral and non-mineral substances, preferably cement raw materials and clinker, by application of moderate to high pressure once or several times followed by disagglomeration of the obtained ground products in the same device. The ground product is extracted by gravimetric feeding in the form of a defined layer from a feeding container, by means of the upper strand, moving in a translatory manner, of an endless plate conveyor which is guided around a drive and deviation tumbler. The ground product is then pre-ground or subjected to other processing pretreatment depending on requirements, for example dried or wetted, and then ground under pressure by an elastically adjusted grinding roller, after which it is disagglomerated in the same device by a high-speed hammering machine.
