Abstract

Treflls-knuseanordning (20) som benytter motsatt roterende valser (24, 26) med overflater (32, 34) av matriser av pyramldeformede projeksjoner (38). Pyramidene (38) står på linje rundt omkretsen slik at gapet mellom de omkretsllggende radene av pyramider danner kontinuerlige V-formede spor (41) som omskriver valsene (24, 26). For å rense valsenes (24, 26) overflater (32, 34) og forhindre oppbygging av treflis (56) eller annet materiale mellom disse, benyttes en skraper (22). Skraperen (22) består av en støtteplate (60) montert stivt i forhold til rammen (30) på hvilken valsene (24, 26) er montert og et utsklftbart, segmentert blad (62) laget av 6 mm tykt rustfritt stål med høy slitasjebestandlghet. Kanten av bladet (62) har triangulære tenner (64) som passer inn mellom pyramlde- radene på valsenes (24, 26) overflater (32, 34). Bladets (62) tenner (64) står l en avstand på 1-2 mm fra pyramidenes (38) sider som danner valsenes (24, 26) overflater (32, 34). Tennene (64) forhindrer oppbygging av materialet mellom de pyramideformede projeksjonene (38).
