Chipolopolo Chozungulira Mano Chozungulira
Mu makampani opanga ma pellet, makina opangira ma ring die kapena ma flat die pellet nthawi zambiri amagwiritsidwa ntchito kukanikiza zinthu za ufa kuti zilowe mu chakudya cha ma pellet. Ma flat ndi ma ring die onse amadalira kayendedwe ka pressure roller ndi die kuti agwire zinthuzo kuti zigwire bwino ntchito ndikuzifinya kuti zikhale bwino. Pressure roller iyi, yomwe imadziwika kuti pressure roller shell, ndi gawo lofunika kwambiri la pellet mill, monga momwe zimakhalira ndi ring die, ndipo ndi imodzi mwa zigawo zomwe zimavala.
Chozungulira cha pressure cha granulator chimagwiritsidwa ntchito kufinya zinthuzo mu mphete. Pamene chozunguliracho chikuphwanyidwa ndi kufinya kwa nthawi yayitali, kuzungulira kwakunja kwa chozunguliracho kumapangidwa kukhala mizere, zomwe zimapangitsa kuti chisawonongeke komanso kuti chikhale chosavuta kugwira zinthuzo.
Mikhalidwe yogwirira ntchito ya ma rollers ndi yoipa kuposa ya ring die. Kuwonjezera pa kuwonongeka kwabwinobwino kwa zinthu zopangira pa ma rollers, silicate, SiO2 mumchenga, chitsulo, ndi tinthu tina tolimba mu zinthu zopangira zimawonjezera kuwonongeka kwa ma rollers. Popeza liwiro la pressure roller ndi ring die zili zofanana, kukula kwa pressure roller ndi 0.4 yokha kuposa kukula kwa mkati mwa ring die, kotero kuchuluka kwa pressure roller ndi kokwera ndi 2.5 kuposa kwa ring die. Mwachitsanzo, moyo wa kapangidwe ka pressure roller ndi maola 800, koma nthawi yeniyeni yogwiritsira ntchito si yoposa maola 600. M'mafakitale ena, chifukwa cha kugwiritsa ntchito molakwika, nthawi yogwiritsira ntchito ndi yochepera maola 500, ndipo ma rollers olephera sangathenso kukonzedwa chifukwa cha kuwonongeka kwakukulu pamwamba.
Kuwonongeka kwambiri kwa ma rollers sikuti kumangochepetsa kuchuluka kwa mafuta a pellet komanso kumawonjezera ndalama zopangira, komanso kumakhudza mwachindunji zokolola. Chifukwa chake, momwe mungakulitsire moyo wa ntchito ya ma rollers a pellet ndi nkhani yofunika kwambiri kwa makampani.
