Pa Julayi 26, 2022, makina owumitsa ndi kuchotsa fumbi la makina opangira feteleza omwe makasitomala aku Sri Lanka adamaliza ndikupereka. Zipangizo zazikulu za gulu ili la zida makamaka ndi zida zowumitsira ndi zochotsera fumbi la mphepo yamkuntho. Makinawa amagwiritsidwa ntchito kukulitsa kufunikira kwa pulojekiti yopanga feteleza ya makasitomala aku Sri Lanka pachiyambi kuti awonjezere mphamvu zopangira. Nthawi yomweyo, zida zowonjezera za mzere wopanga zimaphatikizapo zida zomwe zatumizidwa motsatizana kale: granulator yophatikizana ya organic-inorganic, crusher, mixer, conveyor, ndi zina zotero. Zipangizo zomwe zaperekedwa nthawi ino zimagwiritsidwa ntchito makamaka poyeretsa fumbi pochotsa zinthu zomwe zimafunikira kuti ziwonjezere mphamvu zopangira.
Makhalidwe a choumitsira feteleza Liwiro lozungulira la ng'oma ndi chipangizo chophwanyira likhoza kusinthidwa ndipo limatha kugwira ntchito mosalekeza. Njira yowumitsa yoyenda ndi yotsekedwa imagwiritsidwa ntchito kuti ichepetse kugwiritsa ntchito mphamvu. Zolakwika zochepa, ndalama zochepa zosamalira komanso kugwiritsa ntchito mphamvu zochepa. Powumitsa, imathanso kukwaniritsa cholinga choyeretsa ndi kuchotsa fungo.
Chifukwa tinthu tambiri ta fumbi tomwe timapangidwa pakagwiritsidwe ntchito ka makasitomala ndi toposa 8μm. Kutengera mtundu uwu wa chosonkhanitsira fumbi, tinthu ta 5μm pamwamba pake tili ndi mawonekedwe a kuchotsa fumbi mwachangu komanso kusungunuka mwachangu, kotero chosonkhanitsira fumbi ichi chimasankhidwa. Zinthu zomwe zimaperekedwa nthawi ino zimakhala ndi chimphepo chapadera kuti zithetse vuto la kuipitsa - mpweya wotulutsa utsi ndi fumbi - zomwe zimapangidwa ndi zinthu za kasitomala powumitsa. Mothandizidwa ndi mphamvu ya centrifugal, tinthu ta fumbi timalekanitsidwa ndi mpweya wotuluka ndikulumikizidwa pamwamba pa dzenje lamkati, kenako timagwera mu phulusa pogwiritsa ntchito mphamvu yokoka. Gawo lililonse la chimphepo chamkuntho lili ndi kukula kwake, ndipo kusintha kulikonse mu ubale wa kuchuluka kungakhudze magwiridwe antchito ndi kutayika kwa mphamvu ya chimphepo chamkuntho, momwe kukula kwa chosonkhanitsira fumbi, kukula kwa malo olowera mpweya ndi kukula kwa chitoliro cha utsi ndizomwe zimapangitsa kuti chikhale chachikulu. Samalani kukula kwa kutulutsa kwa mpweya mukamagwiritsa ntchito.
