Zipangizo Zosanthula

Zipangizo zabwino kwambiri zimakhala zopambana. Ntchentche phulusa, Tailings, zomangamanga zinyalala, Shale, Mtsinje silt, Zinyalala nthaka, Loess, Moyo sludge, Gangue.

Ntchito yoyambira kukhazikitsa chomera cha njerwa: Zipangizo zopangira mankhwala ndi zinthu zina (kuphatikiza kutentha kwamkati, ndi zina) kuyesa, pakadali pano kuyeza chinyezi cha njerwa zobiriwira zomwe zimapanga & extrusion.

 

Kusanthula Kwamagetsi

Kusanthula kwamankhwala nthawi zambiri kumayesedwa ngati SiO2, Al2O3, Fe2O3, MgO, CaO, magnesium oxide, sulfure gangue, kutayika poyatsira ndi zina zambiri.

 

SiO2: Zolemba ndizokwera kwambiri, pulasitiki wapansi, ngakhale zili bwino kuyanika mwachangu, komabe zinthu zomalizidwa ndi mphamvu zochepa.

Al2O3: Ngati ndi ochepera 12%, mphamvu yamagetsi yazogulitsayo yafupika, ngati kupitirira 24%, kutentha kowotcha kukuwonjezeka, kukulitsa malasha.

Fe2O3: Okhutira kwambiri kumachepetsa zinthu zomwe zimapangidwanso, zomwe zimapangitsa kuti kutentha kuzikhala kotsika kwambiri.

CaO: Kupereka m'chigawo cha CaCo3 pazinthu zopangira, zotchedwa zinthu zowopsa, Ngati tinthu tating'onoting'ono tolimba kuposa 2mm, titha kuyambitsa njerwa kapena kuphulika poyaka.

MgO: Pomwe zimakhala zochepa, apo ayi, zinthu zomwe zimakula mosavuta zimapangitsa magnesium, kuyambitsa hoarfrost yoyera.

Sulfa Dagan: Kukhala sulphate muzopangira, zomwe zili mkati siziyenera kupitilira 1%. Mukayaka, ipangitsa SO2 ndikuwononga zida zopangira, zovulaza thanzi la ogwira ntchito.

Kutaya poyatsira: Zoyambitsa ndi zinthu zopangira. Ngati kutayika kwakukulu pamayeso, kuchuluka kwa mabowo pazogulitsa.
