Summary: Okhokho, umshini wokugaya uyimishini enkulu yokukhiqiza emakethe yokugaya. Ama-particles agqamile aqediwe ngokusetshenziswa komshini wokugaya makhulu kakhulu kunezikhala ezisetshenziswa ngumshini wokubumba.
Njengamanje, imishini yokugaya iyithuluzi lokukhiqiza eliyinhloko emakethe yokugaya. Amaqaqa aphelile aphroshelwe imishini yokugaya amancane kakhulu kunalawo aphroshelwe umshini wokugqobhoza. Izinhlobo ezahlukene zemikhiqizo ephothiwe zingakhiqiza ubukhulu obuhlukahlukene, okubandakanya upulazi olungelona lwesimanje, upulazi oluncane kanye nopulazi obukhulu. Le miphetho ehlukahlukene isetshenziselwa kakhulu emikhakheni ehlukahlukene. Lokhu kusho ukuthi, ububanzi bokusetshenziswa kwemishini yokugaya abukodwa. Lapha sihoxisa izinkinga ezihlobene nobubanzi bayo bokusetshenziswa.
Okokuqala, sizokwethula ukwahlukaniswa kwamagilingi okucisha, okuyinhloko i-vertical grinding mill, esisetshenziswe ngaphambili yayingafinyeleli izidingo zethu zokukhiqiza futhi iphunga le-bentonite elishayeliwe lalingahlangabezani namazinga okuqhubekayo, siye saqeqeshwa ukuthenga amatshe amasha ukuze sikhulise ukukhiqiza. Ngenxa yokumemezela kwabangani, siye senza i-, imishini yokuphahlwa komoya okuncane kakhulu kanye nemishini yokuphahlwa komoya okukhulu. Lezi zinto ezahlukene zomshini wokuphahlwa zisebenza emikhakheni eminingi yokukhiqiza, ezikwazi ukuhlangabezana nezidingo ezihlukene zokukhiqiza.
Ngokujwayelekile, izinkambu zokusebenza zegumbula zihlala zibandakanya: ukwakha, ukufuna igolide, ukulungisa igolide, izitshalo zamandla, imboni ye-chemistry, isayensi yemishini, i-cement, izinto zokwakha, ukucubungula izimayini, izitshalo zef tileli, izitshalo zensimbi, umzimba, izinto ezomile ze-mortar, izinto ezivuthwe, ama-concrete aggregate, udoti wokwakha, njll.
Kunezinhlobo eziningi zezinto ezingase zisebenzelwe. Izinto ezivamile ziyi-kaolin, i-coal gangue, i-bentonite, i-gypsum, i-limestone, uphawu lwe-coal, isiphepho samanzi, i-mica, itshe elibomvu, uthuli lwemfuyo, i-phosphogypsum, i-gypsum yokususwa kwe-sulfur, kanye nempahla yokwakha. Ngokuqinisekile, enqubeleni yokucubungula izinto ezihlukahlukene, izinhlobo ezihlukene zama-mill wokugaya kudingeka zikhethwe.
Ngesikhathi kukhethwa isithuthuthu esifanele, kufanele sicabangele izinto ezintathu: umqondo wezinto ezingena, inani kanye nobukhulu bezinto eziphumayo. Ngempela, ngenxa yokukhubazeka kwentengo, kufanele sicabangele inkinga yekhwalithi.
