Description

Den foreliggende oppfinnelse vedrører en anordning for knusing av relativt mykt materiale, såsom kull, som omfatter en beholder for materialet som tilføres anordningen for å The present invention relates to a device for crushing relatively soft material, such as coal, which comprises a container for the material which is supplied to the device in order to

knuses, og en transportør, innmontert i beholderen, for inn-føring av materialet som skal knuses, mellom knuservalser i tilknytning til anordningen. is crushed, and a conveyor, installed in the container, for introducing the material to be crushed, between crushing rollers in connection with the device.

Formålet ved oppfinnelsen er å frembringe en anordningThe purpose of the invention is to produce a device

av ny type med vesentlige fordeler i forhold til tidligere kjente anordninger. Anordningen ifølge oppfinnelsen kjenne- of a new type with significant advantages compared to previously known devices. The device according to the invention known

tegnes ved at transportøren består av en siktrullesats for utsikting av materiale av tillatt kornstørrelse, og at det, umiddelbart bakenfor knuservalsene (3,4) er anordnet en siktinnretning for utskilling av det knuste materiale fra uknus- is drawn in that the conveyor consists of a screening roller set for screening material of permitted grain size, and that, immediately behind the crusher rollers (3,4), a screening device is arranged for separating the crushed material from uncrushed

bare, uønskete gjenstander, såsom stener og trepartikler. Oppfinnelsen gjør det mulig å anvende knuservalser av redusert størrelse og kraft, i og med at en stor del av materialet som skal knuses, utsiktes på et tidligere stadium og ikke vil passere gjennom valsene. Siktinnretningen bakenfor knuservalsene i samme anordning utskiller de uønskete substanser, uten at dette krever noen egen siktmekanisme. bare, unwanted objects, such as stones and wood particles. The invention makes it possible to use crushing rollers of reduced size and power, in that a large part of the material to be crushed is screened at an earlier stage and will not pass through the rollers. The screening device behind the crusher rollers in the same device separates the unwanted substances, without this requiring any separate screening mechanism.

En fordelaktig utførelsesform av oppfinnelsen kjenne-* tegnes ved at transportøren heller noen grader oppad i transportretningen. Sikteffekten øker når massestrømmen således bibringes en noe stigende bevegelse. An advantageous embodiment of the invention is characterized by the conveyor tilting a few degrees upwards in the direction of transport. The visibility effect increases when the mass flow is thus imparted with a somewhat upward movement.

En annen utførelsesform av oppfinnelsen kjennetegnesAnother embodiment of the invention is characterized

ved en for-knuser som er anordnet i tilknytning til transpor-tøren. For-knuseren sønderdeler de største fragmenter, samtidig som det dannes mindre, knusningspartikler som utskilles ved hjelp av siktrullesatsen. by a pre-crusher which is arranged in connection with the conveyor. The pre-crusher breaks up the largest fragments, while at the same time smaller, crushing particles are formed, which are separated with the help of the screening roller set.

Oppfinnelsen vil bli nærmere beskrevet i det etterfølgende under henvisning til den medfølgende tegning som viser et snitt av anordningen ifølge oppfinnelsen. The invention will be described in more detail below with reference to the accompanying drawing showing a section of the device according to the invention.

Anordningen omfatter en beholder 1 for kullmaterialeThe device comprises a container 1 for coal material

som tilføres for knusing. En rulletransportør 2 for innføring av kullmateriale som skal knuses mellom knuservalser 3 og 4 which is supplied for crushing. A roller conveyor 2 for introducing coal material to be crushed between crushing rollers 3 and 4

i tilknytning til anordningen, er innmontert i beholderen.in connection with the device, is installed in the container.

En siktinnretning 5 for utskilling av knust kullmateriale 6A screening device 5 for separating crushed coal material 6

fra uknusbareStener og trepartikler 7, er anordnet bakenfor knuservalsene. Transportøren består av en siktrullesats hvori de allerede ferdigknuste fragmenter 8 i kullmaterialet som innstrømmer i beholderen 1, utsiktes. Transportøren heller noen grader oppad i transportrefningen. Det er i tilknytning til transportøren 2 anordnet en for-knuser 9 som sønderdeler de største fragmenter til passende størrelse for knuservalsene. from unbreakable Stones and wood particles 7, are arranged behind the crusher rollers. The conveyor consists of a screening roller set in which the already crushed fragments 8 in the coal material flowing into the container 1 are screened. The conveyor tilts a few degrees upwards in the transport rack. A pre-crusher 9 is arranged in connection with the conveyor 2, which breaks up the largest fragments into a suitable size for the crusher rollers.

Kullmaterialet som skal knuses, innmates i anordningens beholder 1, hvor siktrullesatsen 2 utskiller de kullstykker 8 av passende, endelig størrelse, som allerede forefinnes i kullmaterialet som tilføres beholderen 1. Det øvrige materiale videreføres til for-knuseren 9, hvor de største fragmenter knuses til mindre størrelse. I forbindelse med for-knusingen blir det også dannet mindre kullstykker 10 som siktes i siktrullesatsen og derved faller gjennom denne. Den egentlige knusing finner sted mellom knuservalsene 3 og 4. Stener og trestykker kan også havne mellom valsene 3 og 4, og den ene av valsene vil i slike tilfeller gi etter i slik grad at nevnte gjenstander kan passere gjennom valsene. Disse gjenstander utskilles i den underliggende siktinnretning 5. Samtlige knuste partikler overføres til en transportrenne (ikke vist) under anordningen, for videretransportering. The coal material to be crushed is fed into the device's container 1, where the screening roller set 2 separates the coal pieces 8 of suitable final size, which are already present in the coal material fed into the container 1. The other material is passed on to the pre-crusher 9, where the largest fragments are crushed to smaller size. In connection with the pre-crushing, smaller pieces of coal 10 are also formed, which are sieved in the sieve roll set and thereby fall through this. The actual crushing takes place between the crusher rollers 3 and 4. Stones and pieces of wood can also end up between the rollers 3 and 4, and one of the rollers will in such cases yield to such an extent that said objects can pass through the rollers. These objects are separated in the underlying screening device 5. All crushed particles are transferred to a transport chute (not shown) below the device, for further transport.

Da en meget stor del av kullmaterialet som skal knuses foreligger, allerede ved fremkomsten i anordningen, i slik form at det ved hjelp av siktrullesatsen 2 kan utsiktes direkte i anordningen, uten å måtte passere mellom knuservalsene 3 Since a very large part of the coal material to be crushed is already present in the device when it appears, in such a form that it can be viewed directly in the device with the help of the screening roller set 2, without having to pass between the crusher rollers 3

og 4, er knuservalsenes kraftbehov atskillig mindre enn ved tidligere kjente anordninger. and 4, the crusher rollers' power requirement is considerably less than with previously known devices.

Det vil være åpenbart for den fagkyndige, at oppfinnelsens ulike utførelsesformer kan variere innenfor rammen av de etter-følgende krav. It will be obvious to the person skilled in the art that the various embodiments of the invention may vary within the framework of the following claims.
