    • The invention relates to a method for grinding mill material and to a roller mill and is suited in particular to a finest grinding of relatively hard and dry materials, for example cement clinker and granulated blast furnace slag and also for relatively large roller mills.In order to avoid mill vibrations due to over-grinding of the mill material and to reduce the specific work requirement as well as increasing the throughput a fine material nozzle is arranged after each grinding roller, from which fine material nozzle an air jet with defined impulse is directed from above onto a fine material concentration zone. The fine material concentration zone is formed directly after the grinding zone of each grinding roller and is virtually free of supplied material to be ground and accumulated on a retention rim region. The fine material blown outwards and upwards is fed to a rising conveying air flow and subsequent classifying process.
    • 本发明涉及一种用于研磨研磨材料和辊磨机的方法,特别适用于相对硬和干的材料(例如水泥熟料和粒状高炉矿渣以及相对较大的辊磨机)的最佳研磨。 为了避免由于研磨材料过度研磨引起的磨机振动,并且为了降低特定工作要求以及提高生产量,在每个研磨辊之后设置精细喷嘴,精细材料喷嘴具有限定冲程的空气喷射 从上方引导到细料浓度区。 精细材料浓度区域直接在每个研磨辊的研磨区之后形成,并且基本上不含待研磨的物料并且积聚在保持边缘区域上。 向外吹出的精细材料被送入上升的输送空气流和随后的分级过程。
