Kun hienojakoista ainetta, esim. malmirikastetta muutetaan puristeiksi tavanomaisilla puristelautasilla voidaan käyttää yhtä tai useampaa raapimalai-tetta, jolla pidetään briketöintilautasen pohja ja sivuseinät puhtaina ja estetään aineksen kasautuminen. On tunnettua käyttää sekä kiinteitä että pyöriviä raapimia. Raapimapinta kussakin yksittäisessä raapimessa on usein renkaanmuotoinen ja muodostettu kovametallista tai vastaavasta tarkoituksena pienentää raa-pimapinnan kulutusta. Tämä käytetty kovametalli on kuitenkin hyvin kallista hankkia ja kustannukset yhteydessä kulumiseen saattavat muodostua useiksi sadoiksi markoiksi sataa tonnia tuotettuja brikettejä kohden. Tämän johdosta on taloudelliselta merkitykseltään huomattavaa pystyä pienentämään näitä kustannuksia.When a finely divided material, e.g. ore concentrate, is converted into compacts with conventional press plates, one or more scraper devices can be used to keep the bottom and side walls of the briquetting plate clean and to prevent the material from accumulating. It is known to use both fixed and rotary scrapers. The scraper surface in each individual scraper is often annular and formed of carbide or the like for the purpose of reducing the wear of the scraper surface. However, this spent carbide is very expensive to obtain and the cost associated with wear and tear can amount to several hundred marks per hundred tons of briquettes produced. As a result, it is of considerable economic importance to be able to reduce these costs.
Keksijä on nyt havainnut, että voidaan käyttää piikarbidia raapima-aineena. Piikarbidia käytetään tällöin sauvojen muodossa, jotka sovitetaan sisään ympäröivään teräksiseen tai vastaavaan putkeen siten, että alimpana oleva osa sauvasta on vapaana. Piikarbidisauvat voidaan kiinnittää putkeen esim. täyttämällä putki täyteen sulatettua rikkiä tai muuta täyteainetta, joka jähmettyy piikarbidisauvan ja ympäröivän putken väliin. Sitä mukaa kun sauva kuluu voidaan 2 59122 sitä yksinkertaisesti työntää eteenpäin yhdessä ympäröivän putken kanssa. Edullisimmin pelkästään alimpana oleva osa raapimasauvassa muodostuu piikarbi-dista.The inventor has now discovered that silicon carbide can be used as a scraper. The silicon carbide is then used in the form of rods which are inserted into the surrounding steel or similar pipe so that the lowest part of the rod is free. The silicon carbide rods can be attached to the pipe, e.g., by filling the pipe with fully molten sulfur or other filler that solidifies between the silicon carbide rod and the surrounding pipe. As the rod wears out, it can be simply pushed forward along with the surrounding tube. Most preferably, only the lowest part of the scraper rod consists of silicon carbide.
On suoritettu erityisiä kokeita teollisessa mittakaavassa sarjalla erilaisen tyyppisiä raapimia magneetin priketöintiä eli pilleröintiä varten ja tulokset ovat esiteltävissä alempana olevalla taulukolla*Specific experiments have been carried out on an industrial scale with a series of scrapers of different types for magnet briquetting, and the results are shown in the table below *

Kuten tästä taulukosta käy ilmi aikaansaivat sauvat suhteellisen vähän kulumista ja olivat ne paljon halvempia käytössä kuin muut aineet. Kokeet osoittivat myös, että oli tarpeen sauvojen asettelminen uudestaan ainoastaan noin aina 14 päivän välein, mikä merkitsee, että sauvoja käytännössä tarvitsee asetella uudelleen ainoastaan luonnollisten pysäytysten yhteydessäAs can be seen from this table, the rods caused relatively little wear and were much cheaper to use than other materials. The experiments also showed that it was necessary to reposition the rods only approximately every 14 days, which means that in practice the rods only need to be repositioned during natural stops.
