Dab tsi peb yuav tsum tau them sai sai rau hauv cov txheej txheem ntawm pellet tshuab granulation?

Cov khoom siv raw hauv kev tsim cov khoom ua ntej, yuav tsum tau tempered, ces lub siab xav tau ntawm chav yuav tsum ruaj khov (4 ~ 8bar), thiab tempering chav ua ntej tempering yuav tsum de-watered, vim hais tias lub chav muaj ib tug loj npaum li cas ntawm cov dej. , uas yuav ua rau clogging ntawm granulation. Tom qab tempering, cov khoom yog raug mus rau ib tug tej yam kev mob ntawm maturation, uas yuav ho txhim kho tus nqi ntawm cov as-ham nyob rau hauv pub.

Nyob rau hauv cov txheej txheem ntawm granulation, cov av noo thiab kub ntawm cov khoom yuav tsum tau xyuas ntau zaus. Kev ntsuas dej noo yog: tes pinch, cov khoom siv tuaj yeem ua tau zoo li thaiv. Kub yuav tsum sib txawv raws li ntau hom granulation, kom ruaj khov ntawm 75 ~ 95 degree. Qhov txias ntawm cov khoom granulation yuav tsum tsis txhob ceev dhau los yog tsis txaus txias, yog hais tias qhov txias yog ceev heev, nws yuav ua rau saum npoo ntawm cov khoom tawg, cua txias tsis txaus, qhov kub thiab txias heev, nws yuav ua rau cov khoom hygroscopic. , ua rau cov pwm pwm. Cov khoom txias txias yuav tsum ua raws li chav tsev kub.
