Isitini esijikelezayo se-simende esiphikisayoiwuhlobo oluyinhloko lwendwangu yokushisa okuphezulu yokukhiqiza usimende ama-rotary obstruction. Njengengxenye ebalulekile yokuvikela yezinhlelo ze-oven, ithinta ngqo ukuzinza kwemishini, ukusebenza kahle kwamandla kanye nokuphila kwenkonzo iyonke. Ama-oven esimende asebenza ezimweni ezimbi kakhulu ngokushisa okuphezulu okuqhubekayo, ukujikeleza okushisa njalo, ukuguguleka komshini kanye nokugqwala kwe-alkali, okwenza izitini eziqinile eziqinile zibe yinto ebalulekile ekukhiqizweni kwe-clinker okuzinzile.
Izindawo zokusebenza ezinzima zidinga ukusebenza okuphezulu okuvela ezitini eziqinile. Imikhiqizo yekhwalithi ephezulu inokumelana okuhle kakhulu nokushisa okuphezulu, ibekezelela amazinga okushisa angaphezu kuka-1350°C ngaphandle kokuguquka noma ukulimala kwesakhiwo. Iphinde inikeze ukumelana okuhle kakhulu nokushisa, imelana nokuqhekeka kanye nokuqhekeka okubangelwa ukushintsha kwezinga lokushisa njalo ngesikhathi sokuqalisa i-oven, ukuvala kanye nokusebenza kwansuku zonke.
Lezi zitini ezimelana nokugqwala zinamandla okumelana nokugqwala kwamakhemikhali ngokumelene nezinto ze-alkaline, amakhemikhali esibabule kanye ne-clinker slag ekhiqizwa yi-calcination, okuvimbela ngempumelelo ukulimala kwendwangu kanye nokuguga ngaphambi kwesikhathi. Amandla azo aphezulu okusebenza kanye nokumelana nokuguguleka kubekezelela ukungqubuzana okuqhubekayo kanye nengcindezi evela ezintweni zokusetshenziswa kanye ne-clinker, okuqinisekisa ukusebenza kwe-kiln isikhathi eside futhi okuzinzile.
Izinhlobo ezahlukene zezitini ezingaphikisi ziklanyelwe izimo zokusebenza zehhavini elihlukanisiwe.
Izitini ze-alumina ephezulu zifanela izindawo zokushisa zangaphambi kwesikhathi kanye nezokushintsha ezinezimbobo ezincane, amandla aphezulu okushisa kanye nokusebenza kahle kwezindleko.
Izitini ze-Magnesia-spinel zilungele izindawo ezishisa kakhulu ngenxa yokuqina okuhle kokushisa kanye nokumelana ne-alkali.
Izitini ezivimbela ukukhuhla zisetshenziswa ezindaweni ezishintshashintshayo zokushisa ukuze kugwenywe ukuxebuka nokwandisa isikhathi sokuphila kwendwangu.
Izitini ezigoqekayo zesimende ezijikelezayo zezinga eliphezulu zakha inani eliphawulekayo lezomnotho ezitshalweni zesimende.
Zinciphisa ukulahleka kokushisa, zikhuphule ukusebenza kahle kokushisa ngo-5%-10% futhi zinciphise izindleko zikaphethiloli. Ukuqina kwazo okuphezulu kunciphisa imvamisa yokushintsha nokulungisa, kunciphisa isikhathi sokungasebenzi kwesitofu futhi kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza jikelele.
Ngamafuphi, izitini eziqinile neziqinile zibalulekile ekukhiqizweni kahle kwesimende. Ukuqina kwazo okuthembekile kokushisa okuphezulu, ukumelana nokugqwala kanye nokuqina kuqinisekisa ukusebenza okuphephile, okuphumelelayo nokungabizi kakhulu kwama-oven ajikelezayo esimende.
Ufuna izitini eziqinile nezisebenza kahle kakhulu zesimende esijikelezayo esinamathelayo esitsheni?
Sinikeza izixazululo eziguquguqukayo ezenziwe ngokwezifiso ezenzelwe amamodeli ahlukahlukene esitofini kanye nezimo zokusebenza. Imikhiqizo yethu isetshenziswa kabanzi ezimbonini zesimende zomhlaba wonke ezinekhwalithi ezinzile, amanani ancintisanayo kanye nokusekelwa kobuchwepheshe bochwepheshe.
Xhumana nathi namuhla ukuthola imingcele yomkhiqizo yamahhala, izixazululo ezenziwe ngokwezifiso kanye nezilinganiso zakamuva zasefektri.
