Nyob rau hauv cov khoom noj pellet ntau lawm, thawj kauj ruam hauv kev tsim cov pellets yog crushed pob kws, soybean pluas noj thiab qee qhov loj ntawm cov khoom noj, sib tov ua ke, cov txheej txheem no yog tib yam li peb tus kheej crusher crushing. Qhov txawv ntawm peb cov crushed pub tsuas yog hais tias cov khoom muaj kev txwv nruj, cov khoom tsis tuaj yeem loj dhau peb tuaj yeem ua peb tus kheej crusher, tab sis feem ntau peb tsis paub tias loj npaum li cas yog qhov tsim nyog.
Tom qab crushing yog muab tso rau hauv lub tshuab tov khoom thiab cov tub ntxhais hu ua thiab cov khoom me me sib tov, sib tov zoo rau hauv lub granulation rau hauv tos granulation. Nyob rau hauv lub sij hawm granulation yuav tsum tau siav hauv 75-85 degrees Celsius chav, thiab tom qab ntawd hauv granulator granulation, peb nco ntsoov tias qhov zoo ntawm cov khoom siv granular nyob ntawm no. Cov pellets zoo dua absorbed tom qab maturing. Qhov yuav tsum tau ya raws ntawm granule yog 14.5, qhov dej noo no tiv taus kev cia, feem ntau peb lub tsev tsis yog raws li qhov yuav tsum tau muaj dej noo.
