Description
Den foreliggende oppfinnelse vedrører parvis anordnete valser for knusing av relativt mykt materiale, f.eks. kull, hvor valseflåtene er utstyrt med ringformet pålagte tannkranser og roterer med forskjellig periferihastighet i motsatte retninger, idet spalten mellom valsene danner knuseråpningen. The present invention relates to rollers arranged in pairs for crushing relatively soft material, e.g. coal, where the roller fleets are equipped with ring-shaped superimposed tooth rings and rotate at different peripheral speeds in opposite directions, the gap between the rollers forming the crusher opening.
Parvis anordnete valser av denne type er tidligere kjent fra DE-off.skrift 27 02 177. Dette valsepar av kjent type har den ulempe, at de perifere avstander mellom valsetennene må Rollers arranged in pairs of this type are previously known from DE-off.skrift 27 02 177. This pair of rollers of a known type has the disadvantage that the peripheral distances between the roller teeth must
være tilstrekkelig store, slik at tennene på den overforlig-gende valse kan opptas i mellomrommene, og av denne grunn er tannantallet lite. Jo større forskjellen er mellom valsenes periferihastigheter desto større må tennenes periferiavstand være. Valsenes periferihastigheter må dessuten være innbyrdes synkronisert, for at valsetennene ikke skal kollidere med hverandre . be sufficiently large, so that the teeth of the overlying roller can be accommodated in the spaces, and for this reason the number of teeth is small. The greater the difference between the peripheral speeds of the rollers, the greater the peripheral distance of the teeth must be. The peripheral speeds of the rollers must also be mutually synchronized, so that the roller teeth do not collide with each other.
Formålet med den foreliggende oppfinnelse er å avhjelpe de ovennevnte mangler. Knusevalseparet ifølge oppfinnelsen kjennetegnes ved at enkeltvalsenes tenner er anordnet i inngrep med hverandre. The purpose of the present invention is to remedy the above-mentioned deficiencies. The crushing roller pair according to the invention is characterized by the fact that the teeth of the individual rollers are arranged in engagement with each other.
I overensstemmelse med oppfinnelsen kan valsenes omkretsflater være tett besatt med knusetenner. Som følge av at tennene befinner seg i inngrep med hverandre, vil det utøves en kom-binert trykk- og skyvevirkning på de kullpartikler som skal knuses. Skyvekraften forsterkes grunnet den i og for seg kjente forskjell i valseperiferihastighet. Tennene på den ene knuservalse føres forbi tennene på den annen knuservalse, hvorved kullet sønderdeles ved skyvevirkning. Det er konstatert at kullet knuses på fordelaktig måte utelukkende ved skyvevirkning. Det har derved lykkes å knuse kull ved lavt energiforbruk. In accordance with the invention, the circumferential surfaces of the rollers can be densely studded with crushing teeth. As a result of the teeth being in engagement with each other, a combined pressure and thrust effect will be exerted on the coal particles to be crushed. The thrust force is enhanced due to the per se known difference in roller peripheral speed. The teeth on one crushing roller are guided past the teeth on the other crushing roller, whereby the coal is broken up by pushing action. It has been established that the coal is advantageously crushed exclusively by thrust. It has thereby succeeded in crushing coal with low energy consumption.
En fordelaktig utførelsesform av oppfinnelsen kjennetegnes ved at baksiden av tennene på valsen med den største rotasjons- An advantageous embodiment of the invention is characterized by the fact that the rear of the teeth on the roller with the greatest rotational

Oppfinnelsen vil bli nærmere beskrevet i det etterfølgende under henvisning til den medfølgende tegning, hvori: The invention will be described in more detail below with reference to the accompanying drawing, in which:
Fig. 1 viser et enderiss av et knuservalsepar.Fig. 1 shows an end view of a pair of crusher rollers.
Fig. 2 viser et fremre sideriss av knuservalseparetFig. 2 shows a front side view of the crusher roller pair
ifølge fig. 1.according to fig. 1.
Omkretsflåtene av valsene i og 2 er utstyrt med ring-The peripheral rafts of the rollers i and 2 are equipped with ring-
formet pålagte tannkranser 3 og 4. Valsene 1 og 2 roterer i hver sin retning med innbyrdes forskjellige periferihastigheter. Den minste av valsene roterer ifølge figuren i urviserretningen, mens den største roterer med større periferihastighet mot urviserretningen. Knuseråpningen dannes av mellomrommet mellom valsene 1 og 2. De enkelte valsers 1 og 2 tannkranser 3 og 4 er slik plassert i forhold til hverandre, at de bringes i innbyrdes inngrep, som vist i fig. 2. Baksiden av tennene 5 shaped superimposed tooth rings 3 and 4. The rollers 1 and 2 rotate in separate directions with mutually different peripheral speeds. According to the figure, the smallest of the rollers rotates in the clockwise direction, while the largest rotates with a greater peripheral speed in the anti-clockwise direction. The crusher opening is formed by the space between the rollers 1 and 2. The tooth rings 3 and 4 of the individual rollers 1 and 2 are placed in relation to each other in such a way that they are brought into mutual engagement, as shown in fig. 2. The back of the teeth 5
på den valse 2 som roterer med størst periferihastighet er avfaset, slik at kullstykkene som havner mellom tennene, lettere kan løsne. Grunnet det store antall tenner på valsenes 1 og 2 omkretsflater, er valsene rikelig utstyrt med skjærekanter. on the roller 2 which rotates with the greatest peripheral speed is chamfered, so that the pieces of coal that end up between the teeth can come loose more easily. Due to the large number of teeth on the circumferential surfaces of the rollers 1 and 2, the rollers are abundantly equipped with cutting edges.
Den største knuservalsen 2 har større periferihastighet ennThe largest crusher roller 2 has a greater peripheral speed than
den minste valsen. Da den minste knuservalsen er utstyrt med tenner av rektangulær form, sett fra siden, vil også tennenes bakside danne en skjærekant. Mellomrommet som avgrenses av valsene 1 og 2, omfatter et større antall skjæretenner og the smallest roller. As the smallest crushing roller is equipped with teeth of a rectangular shape, seen from the side, the back side of the teeth will also form a cutting edge. The space delimited by rollers 1 and 2 includes a larger number of cutting teeth and

Det vil være åpenbart for den fagkyndige, at de forskjellige utførelsesformer av oppfinnelsen kan varieres innenfor rammen av de etterfølgende krav. It will be obvious to the person skilled in the art that the different embodiments of the invention can be varied within the scope of the following claims.
