Abstract

1. Jauhatusjärjestely veteen suspendoitujen selluloosakuitujen jauhamiseksi jauhatusraon (1) muodostavien kahden, toistensa suhteen liikkuvan kartiomaisen jauhatuspinnan (3, 4) välissä, joissa on jauhatusliuskoja (6) ja niiden välissä jatkuvia uria (7), jolloin vähintään yksi jauhatuspinta (3) pyörii kartioakselin ympäri ja jauhatusliuskat (6) jatkuvat vastaavalla kartiomaisella jauhatuspinnalla (3, 4) siten, että suuntakomponentti on säteittäinen pyörimisakseliin (10) nähden, tunnettu siitä, että jauhatusrakoon (1) nähden kohtisuorassa jatkuvat jauhatusliuskojen (6) sivupinnat koostuvat kulloinkin useista suorista, keskenään kulmassa olevista säteittäisesti ulospäin suuntautuneista osioista ja ainakin yksi jauhatuspinta (3, 4) koostuu useista, kehäsuunnassa vierekkäin järjestetyistä jauhatussektoreista (8), jolloin kunkin jauhatussektorin (8) jauhatusliuskat (6) jatkuvat kulloinkin keskenään yhdensuuntaisesti. Lisäksi suojavaatimukset 2-14.Grinding arrangement for grinding cellulose fibers suspended in water between two mutually moving conical grinding surfaces (3, 4) forming a grinding gap (1) with grinding strips (6) and continuous grooves (7) therebetween, wherein at least one grinding surface (3) rotates on a conical axis around and the grinding strips (6) extend on a corresponding conical grinding surface (3, 4) so that the directional component is radial with respect to the axis of rotation (10), characterized in that the continuous side surfaces of the grinding strips (6) and the at least one grinding surface (3, 4) consists of a plurality of circumferentially arranged grinding sectors (8), the grinding strips (6) of each grinding sector (8) in each case continuing parallel to each other. In addition, protection requirements 2-14.
