Abstract (en)
[origin: DE4442099A1] The invention concerns a roller mill with a rotating pan (2), grinding rollers (6) which roll over the pan and retaining devices (10) designed to influence the movement between the grinding rollers of the material being ground. In order to raise the throughput of such a mill, while keeping capital costs low, the invention calls for efficient, wear-resistant retention devices (10) to be located between the grinding rollers (6), each device comprising a rotating wall made up of one or more retention rollers (10). The retention rollers have retention faces (12, 15) which block the movement of material outwards, thus retaining it for further grinding. In a first embodiment, one retention face (12) is the inwards-facing side of the retention roller. In another embodiment, the retention rollers are fitted with radially projecting rings (17), thus giving additional retention faces (15).
