Abstract

Valssimyllyssä on runko, ainakin yksi valssipari, joka käsittää ensimmäisen valssin (12) ja toisen valssin (14), jotka ensimmäinen ja toinen valssi ovat rinnakkain siten, että niiden välissä on rako (16). Raon leveys on säädettävissä ensimmäisen valssin ja toisen valssin välistä etäisyyttä muuttamalla ja ensimmäinen ja toinen valssi on yhdistetty toisiinsa voimansiirtomekanismilla, joka on sovitettu välittämään ensimmäisen valssin pyörimisliike toiseen valssiin halutulla välityssuhteella. Mainittu voimansiirtomekanismi käsittää vapaakytkimen (72), joka on järjestetty sallimaan toisen valssin pyöriminen välityssuhteen perusteella määräytyvää pyörimisnopeutta suuremmalla pyörimisnopeudella.The roller mill has a frame, at least one pair of rollers, which comprises a first roller (12) and a second roller (14), the first and second rollers being parallel with a gap (16) between them. The gap width is adjustable by changing the distance between the first roller and the second roller, and the first and second rollers are connected to each other by a power transmission mechanism, which is adapted to transmit the rotational movement of the first roller to the second roller at a desired transmission ratio. Said power transmission mechanism comprises a freewheel (72) which is arranged to allow the second roller to rotate at a rotational speed greater than a rotational speed determined on the basis of the transmission ratio.
