Description
538 2 System for en krossplatta Uppfinningen avser ett system fOr en krossplatta, sarskilt en krossplatta avsedd att anvandas i en sa kallad kaftkross eller liknande. The invention relates to a system for a crushing plate, in particular a crushing plate intended to be used in a so-called shaft crusher or the like.
Det finns olika slags krossar for krossning av material. En sorts kross som är kand sedan lange är en kaftkross som har en kaft med en rOrlig krossyta och en stillastaende krossyta, som krossmaterialet placeras mellan krossytorna och krossas nar den rorliga krossytan trycks mot den stillastaende krossytan. There are different types of crushers for crushing materials. A type of crusher that has been known for a long time is a shaft crusher which has a shaft with a movable crushing surface and a stationary crushing surface, which the crushing material is placed between the crushing surfaces and crushed when the movable crushing surface is pressed against the stationary crushing surface.
Krossytorna ar fiirsedda med ett flertal krossplattor som monteras pa ett ramverk anordnat pa krossytorna. Vanligtvis anvands 2-4 krossplattor pa vardera krossyta. The crushing surfaces are provided with a plurality of crushing plates which are mounted on a framework arranged on the crushing surfaces. Usually 2-4 crushing plates are used on each crushing surface.
De tidigare kanda krossplattorna är gjutna i gjutgods i ett enda stycke. Varje krossplatta är forsedd med ett bakstycke som monteras i ramverket och tander som ar riktade mot materialet som skall krossas. Bakstycket motsvarar ca 70% gjutgodsmaterialet, och endast ca 30% av materialet är del av krosskammarna som slits av krossmaterial. En vanlig typ av krossplatta vager ca 1000 kg. The previously known crushing plates are cast in castings in a single piece. Each crushing plate is provided with a back piece which is mounted in the framework and teeth which are directed towards the material to be crushed. The backing corresponds to about 70% of the casting material, and only about 30% of the material is part of the crushing chambers which are worn by crushed material. A common type of crushing plate weighs about 1000 kg.
Nar tanderna pa krossplattan slitits ner av krossmaterialet byts krossplattan ut och ersatts med en ny krossplatta. When the teeth on the crushing plate have been worn down by the crushing material, the crushing plate is replaced and replaced with a new crushing plate.
Detta innebar att hela bakstycket av krossplattan kasseras vid utbytet, vilket medfor stora materialforluster. Den kasserade krossplattan kan forvisso atervinnas men med avsevard energiatgang i form av transporter och nedsmaltningsarbete, vilket ocksa är negativt ur miljohanseende. Utover det är kostnaderna for varje krossplatta hog eftersom ravarupriserna idag är avsevart hOgre an tidigare. This meant that the entire back piece of the crushing plate was discarded during the replacement, which entailed large material losses. The discarded crushing plate can certainly be recovered, but with considerable energy access in the form of transport and smelting work, which is also negative from an environmental point of view. In addition, the costs for each crushing plate are high because raw material prices today are considerably higher than before.
Uppfinningen har till syfte att astadkomma ett system for en krossplatta som pa ett enkelt satt minskar materialfOrbrukningen och sanker kostnaderna for anvandarna av krossplattor. The object of the invention is to provide a system for a crushing plate which in a simple way reduces the material consumption and reduces the costs for the users of crushing plates.
Detta uppnas med systemet for en krossplatta enligt uppfinningen, som har sardragen angivna i krav 1 samt en fastplatta for systemet for en krossplatta enligt uppfinningen med sardragen angivna i krav 14 och krossprofilen for systemet for en krossplatta enligt uppfinningen med sardragen angivna i krav 15. This is achieved with the system for a crushing plate according to the invention, which has the wound features stated in claim 1 and a fixed plate for the system for a crushing plate according to the invention with the wounds stated in claim 14 and the crushing profile for the system for a crushing plate according to the invention.
FOrdelaktiga utforingsformer av uppfinningen framgAr av underkraven. Advantageous embodiments of the invention appear from the subclaims.
En fordel med systemet for krossplattan enligt uppfinningen är att genom att anvanda en grundplatta av stAlplAt sjunker framstallningskostnaden for krossplattan. An advantage of the system for the crushing plate according to the invention is that by using a base plate of steel plate, the manufacturing cost of the crushing plate decreases.
Eftersom grundplattan inte kommer i kontakt med krossmaterialet under operation, slits inte stalplaten och kan dart& ateranvandas som grundplatta. Since the base plate does not come into contact with the crushing material during operation, the steel plate does not wear and can be dart & reused as a base plate.
Detta innebar att kostnaden sanks avsevart da endast de nedslitna krossprofilerna behover bytas, samt vid behov aven slitplaten, istallet for att byta hela krossplattan som är den vanligaste losningen idag. This meant that the cost was reduced considerably as only the worn crushing profiles need to be replaced, and if necessary also the wear plate, instead of replacing the entire crushing plate, which is the most common solution today.
Den uppfinningsenliga losningen medfor darmed en avsevard besparing av material. 1 538 2 Dessutom kan materialet i grundplattan vara av ett billigare slag an slitplaten och krossprofilerna, vilket ocksa är en kostnadsbesparing. Dessutom ar det battre ur miljOsynpunkt att inte behova kassera en hel krossplat vane gang da krosskammarna an slitna, vilket sker idag. The solution according to the invention thus entails a considerable saving of material. 1 538 2 In addition, the material in the base plate can be of a cheaper type than the wear plate and the crushing profiles, which is also a cost saving. In addition, it is better from an environmental point of view not to have to discard an entire crushing plate as usual when the crushing chambers are worn, which is happening today.
Uppfinningen beskrivs nedan i detalj med hanvisning till flera utforingsformer som visas i bifogade ritningar dar Figur la visar en vy over ovansidan av en utforingsform av systemet for en krossplatta enligt uppfinningen. The invention is described in detail below with reference to several embodiments shown in the accompanying drawings, in which Figure 1a shows a view of the upper side of an embodiment of the system for a crushing plate according to the invention.

Figur 3a-3b visar andra utforingsformer av fastplattan for ett system enligt uppfinningen. Figures 3a-3b show other embodiments of the fixed plate for a system according to the invention.
Figur 4 visar en annan utforingsform av en krossprofil. Figure 4 shows another embodiment of a crushing profile.
Figur la — id visar ett system for en krossplatta 1 enligt uppfinningen som innefattar en bottenplatta 2 bestaende av en grundplatta 3 och en fastplatta 4 . Pa bottenplattans oversida 2i ar ett flertal krossprofiler 5 lOstagbart monterade. Figure 1a - id shows a system for a crushing plate 1 according to the invention which comprises a bottom plate 2 consisting of a base plate 3 and a fixed plate 4. On the upper side 2i of the base plate, a plurality of crushing profiles 5 are removably mounted.
Grundplattan 3 visad i figur lb har en undersida 6 som fixeras mot en ram 7 i en krossmaskin (ej visad i figur) samt en oversida 8 som anligger mot fastplattans undersida 9. I en annan utforingsform kan grundplattan anligga direkt mot undersidan av de lOstagbara krossprofilerna (ej visad i figur). The base plate 3 shown in figure 1b has an underside 6 which is fixed to a frame 7 in a crushing machine (not shown in figure) and an upper side 8 which abuts against the underside 9 of the fixed plate. In another embodiment the base plate can abut directly against the underside of the removable crushing profiles (not shown in figure).
Grundplattan 3 bestar av en skiva av stal av konventionellt slag, exempelvis en valsad stalplat exempelvis av den vanligt forekommande stalkvaliteten 355. I en alternativ utforingsform an grundplattan gjord av hardat borstal. The base plate 3 consists of a sheet of steel of a conventional type, for example a rolled steel plate, for example of the commonly used steel grade 355. In an alternative embodiment, the base plate is made of hardened brush steel.
Hardat borstal har de fordelaktiga mekaniska egenskaperna att det ar extremt motstandskraftigt mot notning och ar speciellt anvandbart i hoghallfasta strukturella tillampningar, vilket ger en langre livslangd pa strukturerna och lagre kostnader ifraga om nOtning och Grundplattan 3 framstalls genom att en ohardad stalplat skars till forutbestarnd storlek och form. Grundplattan är forsedd med genomgaende hal 10 samt forsankningsurtag 11 for att mottaga bultforband avsedda att lostagbart montera fastplattan 4 och/eller krossprofilerna 5 vid grundplattan. Halens 10 antal och placering pa plattan anpassas till krossprofilernas placering och de krafter som paverkar krossprofilerna under operation. 2 538 2 Det är fordelaktigt att grundplattan 3 framstalls av stal av konventionellt slag, det relativt sett mjukare materialet an hardat borstal, tar upp krafterna fran krossoperationen och har en dampande funktion som medfiir god anliggning mot 5 krossmaskinens ramverk 7. Hardened brush brush has the advantageous mechanical properties that it is extremely resistant to wear and is especially useful in high-strength structural applications, which gives a longer service life of the structures and lower costs if welded and the base plate 3 is produced by cutting an uncured steel plate to a predetermined size and form. The base plate is provided with a through hole 10 and a countersunk recess 11 for receiving bolted joints intended to releasably mount the fixed plate 4 and / or the crushing profiles 5 to the base plate. The number and placement of the tail on the plate is adapted to the placement of the crushing profiles and the forces that affect the crushing profiles during operation. It is advantageous that the base plate 3 is made of steel of conventional type, the relatively softer material than hardened brush bristles, absorbs the forces from the crushing operation and has a steaming function which provides a good abutment against the framework 7 of the crushing machine.
Fastplattan 4 ar utformad som en slitplat, och är utformad att placeras mellan grundplattan 3 och krossprofilerna 5. Fastplattan 4 innefattar en platskiva av hardat borstal. Fastplattan framstalls genom att en skiva av ohardat borstal skars till forutbestamd storlek och form och fOrses med genomgaende hal 12. Darefter hardas fastplaten till en fOrutbestamd hardhet. Placeringen av de genomgaende halen korresponderar mot de genomgaende halen pa grundplattan 3. Fastplattan visad i figur 1 har en plan fastyta 13 vand mot krossprofilerna 5. The fixed plate 4 is designed as a wear plate, and is designed to be placed between the base plate 3 and the crushing profiles 5. The fixed plate 4 comprises a hard disk of hardened brush plate. The fixed plate is made by cutting a sheet of uncured brush bristle to a predetermined size and shape and providing a continuous hole 12. The hard plate is then cured to a predetermined hardness. The location of the through-holes corresponds to the through-holes on the base plate 3. The fixed plate shown in figure 1 has a flat fixed surface 13 water against the crushing profiles 5.
Fastplattan 4 monteras lostagbart pa grundplattan 3 med bultforband 14. The fixed plate 4 is detachably mounted on the base plate 3 with bolted connection 14.
Bade fastplattan och krossprofilerna är utformade for att vara utbytbara medans grundplattan behalls och ateranvands. Both the fixed plate and the crushing profiles are designed to be replaceable while the base plate is retained and reused.
Under krossoperationen kan krossmaterial komma i kontakt med fastplattan 4, som darmed utsatts for slitage, darfor ar fastplattan utformad sa att den kan bytas ut. During the crushing operation, crushing material can come into contact with the fixed plate 4, which is thus subjected to wear, therefore the fixed plate is designed so that it can be replaced.
Fastplattan byts dock betydligt mer sallan an krossprofilerna. However, the fixed plate is replaced significantly more than the crushing profiles.
Bottenplattan 2 ar pa oversidan 2i forsedd med ett flertal krossprofiler 5. Krossprofilerna framstalls genom att ohardade langstrackta stalelement av borstal med ett fiirutbestamt tvarsnitt kapas till Onskade langder. The bottom plate 2 is provided on the upper side 2i with a plurality of crushing profiles 5. The crushing profiles are produced by cutting uncured elongate steel elements of brush steel with a predetermined cross section to desired lengths.
Krossprofilerna 5 ar utformade att stracka sig fran en ytterkant 2' pa bottenplattan till en motstaende ytterkant 2" pa bottenplattan 2. The crushing profiles 5 are designed to extend from an outer edge 2 'of the base plate to an opposite outer edge 2' of the base plate 2.
Varje krossprofil 5 kan vara indelad i tva eller fler langstrackta segment 5i,5ii, 5iii med likadant tvarsnitt som monteras efter varandra i langdled. Each crushing profile 5 can be divided into two or more elongate segments 5i, 5ii, 5iii with the same cross section which are mounted one after the other in longitudinal direction.
Exempelvis kan en krossprofil vara tre eller fyrdelad sa aft de olika segmenten kan skiftas till olika positioner pa bottenplattan for att erhalla ett jamnt slitage. For example, a crushing profile can be three or four-part so that the different segments can be shifted to different positions on the base plate to obtain an even wear.
Krossprofilerna 5 kan vara utformade sa att de kan roteras 180 grader kring en axel vinkelrat mot langden, se figuren. Detta är fordelaktigt genom att ojarrint slitage kan kompenseras. The crushing profiles 5 can be designed so that they can be rotated 180 degrees about an axis perpendicular to the length, see the figure. This is advantageous in that unearthly wear can be compensated.
I en alternativ utforingsform har krossprofilen varierande tvarsnitt utmed langden, se figur 4. In an alternative embodiment, the crusher profile has varying cross-sections along the length, see figure 4.
Krossprofilerna forses med hal 15 for mottagande av bultforband. Haien kan vara genomgaende fran undersida till oversida, eller vara utformade som blindhal. The crusher profiles are provided with hall 15 for receiving bolted joints. The shark can be continuous from bottom to top, or be designed as a blind hall.
Darefter hardas krossprofilerna till en forutbestarnd hardhet. The crushing profiles are then hardened to a predetermined hardness.
Det ar fordelaktigt att fastplattan, dvs slitplaten, och krossprofilerna har samma hardhet, da slits materialet pa samma satt. Vanligtvis hardas slitplaten och krossprofilerna till en hardhet motsvarande atminstone 500 Brinell eller hogre. It is advantageous that the fixed plate, ie the wear plate, and the crushing profiles have the same hardness, then the material wears in the same way. Usually the wear plate and the crush profiles are hardened to a hardness corresponding to at least 500 Brinell or higher.
FOretradesvis i intervallet 500-550 Brinell. Flardheten kan dock anpassas efter det 3 538 2 material som skall krossas. Det är naturligtvis tankbart att hardheten är lagre, sasom exempelvis 450-500 Brinell. Preferably in the range 500-550 Brinell. However, the flatness can be adapted to the 3,538 2 material to be crushed. It is of course conceivable that the hardness is lower, such as for example 450-500 Brinell.
I en alternativ utforingsform äí fastplattan hardad till en hogre hardhet an krossprofilerna. In an alternative embodiment, the fixed plate is hardened to a higher hardness than the crushing profiles.
Krossprofilens tvarsnittsform valjs och anpassas till det material som skall krossas. The cross-sectional shape of the crushing profile is selected and adapted to the material to be crushed.
I figur 2a-e visas olika tankbara utforingsformer av krossprofilens tvarsnittsform 5a-e. Figures 2a-e show various conceivable embodiments of the cross-sectional shape 5a-e of the crushing profile.
Tvarsnittet kan vara triangulart, bagformat eller flerhOrnigt i olika former eller en kombination av dessa former. Det flerherniga tvarsnittet kan vara rektangulart eller formad som en likbent parallelltrapets eller liknande. I figur 2d visas en utforingsfrom av krossprofiltvarsnitt 5d som ar avsedd att samverka med en sarskild utforingsform av fastplattan som visas i figur 3b. The cross-section can be triangular, bag-shaped or polygonal in different shapes or a combination of these shapes. The polygonal cross-section may be rectangular or shaped like an isosceles parallelogram or the like. Figure 2d shows an embodiment of a crushed profile cross-section 5d which is intended to cooperate with a special embodiment of the fixed plate shown in Figure 3b.
Krossprofilen 5 har en anliggningsyta 16 som ar vand mot bottenplattan 2 och en krossyta 17 som ar vand mot krossmaterialet. Krossprofilen har tva langsgaende sidoytor 18 som ar vanda mot de intilliggande krossprofilerna. Sidoytorna mot& anliggningsytan langs de nedre kanterna 19. The crushing profile 5 has a contact surface 16 which is water against the bottom plate 2 and a crushing surface 17 which is water against the crushing material. The crusher profile has two longitudinal side surfaces 18 which face the adjacent crusher profiles. The side surfaces towards the abutment surface along the lower edges 19.
Krossprofilerna monteras pa bottenplattan med bultforband, bultar 14, som infors i de genomgaende Mien i bottenplattan samt i de korresponderande Mien i krossprofilen. The crusher profiles are mounted on the base plate with bolted joints, bolts 14, which are inserted into the through holes in the base plate and in the corresponding joints in the crusher profile.
Bultforbandet bestar av bultar 14 som är anpassade fOr de pafrestningar som krossprofilerna utsatts for. The bolt joint consists of bolts 14 which are adapted to the stresses to which the crushing profiles have been subjected.
Det är fordelaktigt att valja en bulttyp av sadant material att bulten slits ner tillsammans med krossprofilen, i synnerhet i det fall dar krossprofilerna ar forsedda med genomgaende hal. It is advantageous to choose a bolt type of such material that the bolt wears down together with the crusher profile, especially in the case where the crusher profiles are provided with a continuous slide.
Krossprofilerna är placerade pa bottenplattan sa att de nedre kanterna av tva intilliggande krossprofiler ligger mycket nara varandra. Det innebar aft det finns eft spel 20 mellan de nedre kanterna hos de intilliggande krossprofilerna for att underlatta monteringen. The crushing profiles are placed on the bottom plate so that the lower edges of two adjacent crushing profiles are very close to each other. This means that there is a clearance 20 between the lower edges of the adjacent crusher profiles to facilitate assembly.
I en annan utfOringsform är krossprofilerna placerade pa bottenplattan sa att de nedre kanterna av tva intilliggande krossprofiler vasentligen anligger varandra. Detta är fOrdelaktigt genom att skjuvkrafter pa krossprofilerna eller tryckkrafter fran krossmaterialet tas upp av fler bultforband. In another embodiment, the crushing profiles are placed on the bottom plate so that the lower edges of two adjacent crushing profiles substantially abut each other. This is advantageous in that shear forces on the crushing profiles or compressive forces from the crushing material are absorbed by more bolt joints.

Sparet anpassas efter krossprofilens form och storlek. Sparet 22 är utformat med sidoytor 23 och bottenyta 24. Sparet är utformat for att anligga mot krossprofilens anliggningsyta 16 samt nedre langsgaende kant 19 utmed krossprofilens sida. Sparen har till syfte att minska paverkan av tvarkrafter pa krossprofilerna under krossoperationen. Sparen underlattar aven vid monteringen av krossprofilerna pa 4 538 2 fastplattan 21 . Naturligtvis ar de genomgaende Mien i fastplattan anordnade i sparen. The spar is adapted to the shape and size of the crushing profile. The recess 22 is formed with side surfaces 23 and bottom surface 24. The recess is designed to abut against the abutment surface 16 of the crusher profile and the lower longitudinal edge 19 along the side of the crusher profile. The purpose of the savings is to reduce the influence of transverse forces on the crushing profiles during the crushing operation. The spares also facilitate the mounting of the crushing profiles on the 53 53 2 2 fixed plate 21. Of course, the continuous Mien in the fixed plate are arranged in the spares.
