Abstract

Valssimyllyssä rehuraaka-aineen murskaamista ja/tai litistämistä varten, 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), säätövälineet ensimmäisen valssin ja toisen valssin välisen etäisyyden muuttamiseksi, voimansiirtomekanismi ensimmäisen valssin pyörimisliikkeen välittämiseksi toiseen valssiin halutulla välityssuhteella, voimansiirtoakseli voimakoneeseen kytkeytymistä varten, syöttölaite (40) rehuraaka-aineen syöttämiseksi ensimmäisen valssin ja toisen valssin väliseen rakoon ja ohjausyksikkö (22) mainittujen säätövälineiden ja syöttölaitteen toiminnan ohjaamista varten. Valssimylly käsittää lisäksi ensimmäisen kierroslukumittarin voimansiirtoakselin pyörimisnopeuden mittaamista varten, joka kierroslukumittari on yhdistetty ohjausyksikköön ja ohjausyksikkö on järjestetty ohjaamaan säätövälineiden ja/tai syöttölaitteen toimintaa mitatun pyörimisnopeuden perusteella.In a roller mill for crushing and/or flattening feed raw material, there is a body, at least one pair of rollers, which comprises a first roller (12) and a second roller (14), which first and second roller are parallel in such a way that there is a gap (16) between them, adjusting means for changing the distance between the first roller and the second roller, a power transmission mechanism for transmitting the rotational movement of the first roller to the second roller with the desired transmission ratio, a power transmission shaft for connecting to the power machine, a feeding device (40) for feeding the feed raw material into the gap between the first roller and the second roller, and a control unit (22) for the operation of said adjusting means and the feeding device for steering. The roller mill also comprises a first tachometer for measuring the rotation speed of the power transmission shaft, which tachometer is connected to the control unit and the control unit is arranged to control the operation of the adjustment means and/or the feed device based on the measured rotation speed.
