Imathiriyeli echasayo esetyenziswa kwinkunkuma eyingozi yokutshisa i-rotary kiln ibalwa ngezinto ezintsonkothileyo nezingazinzanga.Injongo yokubala kukutshisa inkunkuma eyingozi ibe yi-slag nokunciphisa izinga lokunciphisa ubushushu kwintsalela ibe ngaphantsi kwe-5%.xa kungekho crust eziko. ,indlela yokhetho echasayo yenkunkuma enobungozi yokutshisa i-rotary kiln yahluke ngokupheleleyo kuhlobo lwe-rotary kiln.
Kwizinto ezichasayo ezisetyenziswa kwi-rotary kiln kunyango lwenkunkuma enobungozi, ubume bekhemikhali benkunkuma enobungozi buntsonkothile ngenxa yeentlobo ezahlukeneyo, ngoko ke kugqitywe ukuba ukwakheka kweekhemikhali zenkunkuma enobungozi kutshiswa kubushushu obungama-700-1000 kwiikhilo ezijikelezayo, kwaye Ukwakhiwa okuphambili kokukhutshwa kwerhasi emva kokubalwa kwenkunkuma enobungozi kuneasidi encinci.
Kwi-refractory, i-refractory castable kwi-gas ene-acidic inozinzo oluhle, i-AL2O3 SiO2 inkunkuma ejikelezayo ye-rotary kiln yinto efanelekileyo yokuxhathisa i-corrosion kunye ne-castable refractory, xa ukhetha izinto eziphikisayo, kungekhona ukukhethwa kweemveliso eziphikisayo, umxholo we-Fe2O3 kangangoko kunokwenzeka ngenxa ye-Fe2O3 FeCL3 isabela ngayo. Irhasi yeklorini, isigaba segesi, iguquguqukayo kunye nokugqithisa ngaphezulu isitena esiphikisayo, i-sement rotary kiln isetyenziswa ngokuqhelekileyo ekuxhathiseni ukubola kwemveliso yokhuseleko lwendalo esingqongileyo iMagnesia iron spinel isitena, kwinkunkuma enobungozi yokujikeleza iziko lokukhetha izinto ezichaseneyo akufanelekanga, kwindawo enobungozi. inkunkuma rotary iziko feed kunye outlet castable, kufuneka kwakhona kukhethwe isamente ephantsi castable, kuba isamente CaO kunye reaction chlorine, ukubunjwa isigaba ulwelo CaC1 kuya kunciphisa ukumelana nobushushu kunye nozinzo lobushushu eliphezulu lokugalela.
Ekukhethweni kwezinto eziphikisayo, inkunkuma ejikelezayo enobungozi kufuneka isebenzise izinto ezichasayo ezinokumelana nokunxiba kakuhle, ukuzinza kokutshatyalaliswa kwe-thermal kunye nokuxhathisa ukubola. Inkqubo yokuvelisa i-rotary kiln yenkunkuma eyingozi ngokuqhelekileyo isebenzisa inkqubo yokutshisa inkunkuma. Inkunkuma eyingozi yomoya engundoqo ingena kwicala elinye kwaye ubude beziko bufutshane xa kuthelekiswa (umlinganiselo wobude obuyi-3-5m kuphela). Ukusabela kwi-ziko kulula, oko kukuthi, ukusabela kwe-oxidation yokutshisa. Phakathi kweemveliso eziqhelekileyo zangoku, isitena se-mullite sic yimveliso efanelekileyo ngakumbi, kwaye izinto ezichithwayo zingakhethwa i-mullite.
