METHOD AND SYSTEM ARRANGEMENT FOR PROVIDING AND ACTIVATING A RAW MATERIAL

摘要

The invention relates to a method for providing and activating a raw material. The raw material is comminuted by grinding rollers in a mill/classifier combination. The mill/classifier combination is set and operated so as to produce a milled product with a fineness between D50 = 3 μm and D50 = 12 μm. In the process, a part of the milled product is comminuted to a diameter of < 5 μm by means of the mill/classifier combination. The milled product then undergoes further classification in a fine grain classifying assembly which has a separation limit in order to separate a very fine grain with a fineness of < D50 = 6 μm. The invention further relates to a system arrangement for carrying out the method according to the invention.
