Abstract (en)
[origin: WO2014075815A1] The invention relates to a vertical mill for grinding a product to be milled and a method therefor, wherein the vertical mill has a grinding plate and one or more grinding rolls. A blade ring annular channel is provided for a transport gas flow rising around the grinding plate. An annular gap is provided between a downwards projecting middlings cone and the upper range of the grinding rollers through which gap even a fines content is recirculated back to the grinding plate. To overcome this disadvantage, a barrier gas flow is provided flowing from the inside towards the outside, by means of which the recirculation of ground particles of a defined size can be prevented.
