Abstract (en)
[origin: EP0399192A1] In order to ensure that the ability of the rollers to draw in material is improved, in particular for carrying out the material bed milling in the roller gap of a high-pressure roller mill, especially if fines also such as sifted grit of high loose porosity have to be drawn into the roller gap, and in order thus to increase, among other things, the mass throughput capacity of the roller mill and to obtain further advantages, it is proposed according to the invention to arrange at least one pre-compacting roller (15 or 21) in the area above at least one of the two milling rollers (10 or 11) for pre-compacting the feed material before it is drawn into the roller gap. <IMAGE>
