Opfindelsen angår en slaglemølle af den i indledningen til krav 1 angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention

Der kendes sådanne slaglemøller, hvor malekammerets cylindriske væg udgøres af et sold, hvorigennem en fraktion af det malede 5 gods kan fraføres. Dette sold bliver jævnligt tilstoppet og må derfor periodisk renses med driftsstop for slaglemøllen til følge.Such slag mills are known in which the cylindrical wall of the painting chamber is constituted by a screen through which a fraction of the painted material can be carried. This screen is regularly clogged and must therefore be periodically cleaned with a shutdown of the mower.

Fra USA-patent nr. 3.214.105 kendes endvidere en slaglemølle, hvor malekammeret har en fraførselsåbning for malet gods 10 i malekammerets sidevæg samt har fremspring i form af justeringsplader og lejebærere med afbøjningsorganer nær sidevæggen, hvilket erfaringsmæssigt sætter en øvre grænse på ca. 1000 o/m for rotoren.Furthermore, US Patent No. 3,214,105 discloses a slaughter mill, in which the painting chamber has a discharge opening for painted goods 10 in the side wall of the painting chamber and has projections in the form of adjustment plates and bearing carriers with deflection members near the side wall, which experience has an upper limit of approx. 1000 rpm for the rotor.

Sådanne fremspring vil uvægerligt hindre malegodsets rote-15 rende strømning langs malekammerets cylindriske væg, og da nævnte slaglemølle endvidere har en helt lukket bund, vil i hvert fald fugtigt eller olieholdigt malegods hurtigt tilstoppe møllens fraførselsvej for malegods.Such protrusions will inevitably impede the rotating flow of the milling material along the cylindrical wall of the milling chamber, and since said slag mill also has a fully closed bottom, at least moist or oily milling goods will quickly clog the mill's path of milling.

Slaglemøllen ifølge opfindelsen er ejendommelig ved det i 20 den kendetegnende del af krav 1 angivne. Som følge heraf undgås ovennævnte ulemper, og der tilvejebringes en slaglemølle, der arbejder med længere slaglelevetider samt ved lave vedligeholdelses- og reparationsomkostninger, og som ud over at være velegnet til findeling af malegods generelt også er 25 velegnet til formaling af olieholdigt korn og foderstoffer, der på traditionelle slaglemøller hyppigt vil forårsage tilstopning af soldet eller møllens fraførselsåbning for malegods. Møllens luftforbrug kan desuden reduceres til 10-15% af normalværdien for tilsvarende, hidtil kendte møller.The slag mill according to the invention is characterized by the characterizing part of claim 1. As a result, the above-mentioned drawbacks are avoided, and a slaughter mill is provided which works with longer stroke life as well as low maintenance and repair costs, and which, in addition to being suitable for comminuting grinding materials, is generally also suitable for grinding oily grains and feedstuffs, which will often cause clogging of the sill or the mill's discharge opening for painting goods on traditional slaughter mills. The mill's air consumption can also be reduced to 10-15% of the normal value for similar, previously known mills.

30 Dette lave luftforbrug bevirker desuden større sikkerhed mod støveksplosion. Endvidere vil der kunne opereres med langt højere rotoromdrejningstal.30 This low air consumption also provides greater protection against dust explosion. Furthermore, much higher rotor speed can be operated.

En forklaring herpå kan være, at de manglende fremspring sammen med den helt åbne fraførselsbund, hvis tværsnits-areal er mindst lige så stort som malekammerets eller det nederste malekammers bund og forbliver uændret eller voksende i nedadgående retning fra det nederste malekamner, danner en kombination af foranstaltninger, der tillader væsentligt højere rotoromdrejningshastighed end de kendte møllers, højst 3000 o/m, uden risiko for tilstopning af kammer eller udløb eller hindring af slaglernes bevægelse rundt langs den fremspring-fri cylindriske 10 kammervæg. Ved fedtindhold over 6% fungerer møllen ifølge opfindelsen upåklageligt, medens de kendte møller tilstoppes og ideligen får driftsstop. Der er således tilvejebragt et nyt maleprincip, hvor relativhastigheden mellem slagler og malegods under malingen opnås ved en fremspringfri kammer-15 vægs samvirken med slagler, der roterer ved høje omdrejninger på 3.000-10.000 o/m, og det uden at det allerede malede gods på grund af den helt åbne bund kan hindre fraførslen af under maling værende gods.One explanation for this may be that the missing projections, together with the fully open discharge bottom, whose cross-sectional area is at least as large as the bottom of the painting chamber or the lower painting chamber and remains unchanged or growing downward from the lower painting chamber, form a combination of measures which permit substantially higher rotor speed than the known mills, at most 3000 rpm, without the risk of clogging of chambers or outlets or obstruction of the movement of the slag around the projection-free cylindrical chamber wall. At grease content above 6%, the mill according to the invention works impeccably, while the known mills are clogged and are constantly stopped. Thus, a new principle of painting has been provided, whereby the relative velocity between slag and grinding material during the grinding is achieved by the interaction of a projection-free chamber-wall with slats rotating at high revolutions of 3,000-10,000 rpm, and this without the already painted cargo of Due to the completely open bottom, it can prevent the shipment of goods under paint.

Opfindelsen vil i det følgende blive nærmere forklaret 20 i forbindelse med en udførelsesform og under henvisning til tegningen, som viser et udsnit af et aksialsnit gennem en vertikalt stillet slaglemølle ifølge opfindelsen.The invention will be explained in more detail below in connection with one embodiment and with reference to the drawing, which shows a section of an axial section through a vertically positioned impactor according to the invention.

Pra en tilførselstragt øverst til venstre tilføres malegods til slaglemøllen, hvis cylindriske væg 1 indeslut-25 ter tre sammenkoblede og i samme retning roterende rotorer 2, 3 og 4. Slaglemøllen er opdelt i tre sektioner indeholdende hver sin rotor, og mellem sektionerne er anbragt lederinge 5 og 6 for malegodset. Lederingene leder malegodset fra væggen 1 radialt indad og aksialt ned-30 ad til en mindre diameter i slaglemøllen.From a supply funnel in the upper left, grinding material is supplied to the slag mill, whose cylindrical wall 1 includes three interconnected and rotating rotors 2, 3 and 4 in the same direction. The slag mill is divided into three sections containing each rotor, and between the sections are conductor rings. 5 and 6 for the paint. The conduits guide the grind from the wall 1 radially inwardly and axially downward to a smaller diameter in the slag mill.

3 Øverst på slaglemøllen er flere i kreds anbragte, indstillelige lufttilførselsåbninger eller -dyser 8 til regulering af indsugnings- eller blæseluft til slaglemøllen. Indsugningsluften gennem dyserne 8 kan reguleres til 5 mindskning eller forøgelse af materialehastigheden i aksial retning gennem møllen til opnåelse af et optimalt effektforbrug. Rotorernes 2, 3 og 4 og den cylindriske kammervægs 1 akse 9 er her sammenfaldende, men i tilfælde, hvor rotorernes fælles akse er skråtstillet, kan kammervæg-10 gens akse 1 være beliggende højere end rotorernes fælles akse parallelt med denne. Hver rotor er forsynet med et antal slagler 12, der udgør slaglemøllens sliddele, og er hængslet forbundet med respektive rotorer. Hver rotor 2, 3, 4 med slagler 12 er anbragt i sit respektive 15 afsnit eller malekammer 16, 17 og 18 i slaglemøllen.3 At the top of the mower mill are several circularly adjustable air supply openings or nozzles 8 for regulating suction or blower air to the mower. The suction air through the nozzles 8 can be adjusted to reduce or increase the material velocity in the axial direction through the mill to obtain optimum power consumption. Here, the axis 9 of the rotors 2, 3 and 4 and the axis 9 of the cylindrical chamber wall 1 coincide, but in cases where the common axis of the rotors is inclined, the axis 1 of the chamber wall 10 may be located higher than the common axis of the rotors parallel thereto. Each rotor is provided with a plurality of pulleys 12, which constitute the wear parts of the paddle mill, and are hingedly connected to respective rotors. Each rotor 2, 3, 4 with impeller 12 is disposed in its respective 15 sections or grinding chamber 16, 17 and 18 of the impactor.

På tegningen ses møllen med tre sektioner, men dette sektionsantal kan øges eller formindskes til én. Møllen har fortrinsvis variabel hastighed og er velegnet til computerstyret drift. Den variable periferihastighed gør møllen 20 velegnet til homogen formaling, idet slaglernes periferihastighed kan afpasses efter malegodsets art. Ved heterogene materialer indstilles periferihastigheden efter det vanskeligst formalelige gods. Dette gælder, uanset om rotorerne roterer samme vej eller skiftevis roterer i modsatte retnin-25 ger.The drawing shows the mill with three sections, but this section number can be increased or decreased to one. The mill preferably has variable speed and is suitable for computer controlled operation. The variable peripheral speed makes the mill 20 suitable for homogeneous milling, since the peripheral speed of the slag can be adjusted according to the nature of the milling material. For heterogeneous materials, the peripheral speed is set according to the most difficult to formulate goods. This applies whether the rotors rotate in the same direction or alternately rotate in opposite directions.

I tilfælde, hvor malegodset ikke er olieholdigt eller klæbrigt på anden vis, kan kammervæggen 1 i et eller flere nederste malekamre 17, 18 erstattes af en perforeret plade eller sold, medens kammervæggen i det eller de 30 øverste kamre er af massiv plade.In cases where the paint is not oily or otherwise sticky, the chamber wall 1 of one or more lower painting chambers 17, 18 may be replaced by a perforated plate or screen, while the chamber wall of the upper chamber or chamber 30 is of solid plate.
