U-Robert Shenk, we-FLSmidth, unikeza isifinyezo sokuthi izitshalo zikasimende 'eziluhlaza' zingabukeka kanjani esikhathini esizayo esiseduze.
Eminyakeni eyishumi kusukela manje, imboni kasimende izovele ibukeke yehluke kakhulu kunanamuhla.Njengoba amaqiniso okuguquguquka kwesimo sezulu eqhubeka nokushaya, ingcindezi yenhlalo kuma-etters anamandla izokwanda futhi ingcindezi yezezimali izolandela, okuphoqa abakhiqizi bakasimende ukuba benze okuthile.Ngeke sisaba khona isikhathi sokucasha ngemuva kokuhlosiwe noma kumamephu emigwaqo;ukubekezelelana komhlaba wonke kuyobe sekuphelile.Imboni kasimende inesibopho sokulandela zonke izinto ezithembisile.
Njengomphakeli oholayo embonini, i-FLSmidth izwa lesi sibopho ngokujulile.Inkampani inezixazululo ezitholakalayo manje, nokuningi okusathuthukiswayo, kodwa okubalulekile wukuxhumana nabakhiqizi bakasimende ngalezi zixazululo.Ngoba uma ungakwazi ukubona ngeso lengqondo ukuthi isitshalo sikasimende sizobukeka kanjani - uma ungakholelwa kuso - ngeke kwenzeke.Lesi sihloko sichaza kabanzi ngesitshalo sikasimende sesikhathi esizayo esiseduze, kusukela enkwalini kuya ekuthumeni.Kungase kungabonakali kwehluke kakhulu esitshalweni ongasibona namuhla, kodwa kunjalo.Umehluko usendleleni esebenza ngayo, okufakwa kuyona, nobunye ubuchwepheshe obusekelayo.
Inkwali
Nakuba ukuguqulwa okuphelele kwenkwali kungabonwa kusengaphambili esikhathini esizayo esiseduze, kuzoba nomehluko obalulekile.Okokuqala, ukufakwa kukagesi kokukhishwa kwempahla kanye nokuthutha - ukushintsha kusuka kudizili kuya ezimotweni ezinamandla kagesi ekwalini kuyindlela elula yokunciphisa ukukhishwa kwekhabhoni kule ngxenye yenqubo yesimende.Eqinisweni, iphrojekthi yakamuva yokuhlola inkwali yase-Swedish yehliswe ngo-98% ekukhishweni kwekhabhoni ngokusebenzisa imishini kagesi.
Ngaphezu kwalokho, inkwali ingase ibe indawo eyedwa ngoba eziningi zalezi zimoto zikagesi zizobe sezizimele ngokuphelele.Lokhu kufakwa kukagesi kuzodinga imithombo yamandla eyengeziwe, kodwa eminyakeni eyishumi ezayo, izitshalo zikasimende ezengeziwe kulindeleke ukuthi zilawule ukutholakala kwazo kwamandla ngokwakha umoya nokufakwa kwelanga esizeni.Lokhu kuzoqinisekisa ukuthi banamandla ahlanzekile abawadingayo ukuze banikeze amandla hhayi nje ukusebenza kwabo kwenkwali kodwa bakhulise ukufakwa kukagesi kuyo yonke indawo.
Ngaphandle kokuthula okuvela ezinjinini zikagesi, izinkwali zingase zingabonakali zimatasa njengaseminyakeni 'ye-peak clinker', ngenxa yokwanda kokuthathwa kwezinto zikasimende ezengeziwe, okuhlanganisa nobumba olubaliwe, okuzoxoxwa ngakho ngokuningiliziwe kamuva esihlokweni.
Ukuchoboza
Imisebenzi yokuchoboza izohlakanipha futhi iphumelele kakhudlwana, isebenzisa ubuchwepheshe be-Industrial 4.0 ukonga amandla nokwandisa ukutholakala.Amasistimu okubona aqhutshwa ngomshini azosiza ekuvimbeleni ukuvinjwa, kuyilapho ukugcizelela ezingxenyeni ezigqoke kanzima kanye nokugcinwa kulula kuzoqinisekisa ukuphumula okuncane.
Ukuphathwa kwezitoko
Ukuxuba okusebenza kahle kakhulu kuzokwenza ukulawulwa kwamakhemikhali nokusebenza kahle kokugaya - ngakho-ke ukugcizelelwa kulesi sigaba sesitshalo kuzoba sebuchwephesheni obuthuthukisiwe bokubona inqwaba yesitoko.Izinto zokusebenza zingabukeka zifana, kodwa ukulawulwa kwekhwalithi kuzocwengisiswa kakhulu ngenxa yokusetshenziswa kwezinhlelo zesofthiwe ezifana ne-QCX/BlendExpert™ Pile ne-Mill, ezisiza abaqhubi bezitshalo zikasimende ukuthi bathole ukulawula okukhulu kokuphakelayo kwabo kokugaya okungavuthiwe.Ukumodela kwe-3D nokuhlaziya okusheshayo, okunembayo kunikeza ukuqonda okukhulu ngangokunokwenzeka ekubunjweni kwenqwaba, okuvumela ukuthuthukiswa kokuhlanganisa ngomzamo omncane.Konke lokhu kusho ukuthi impahla eluhlaza izolungiselelwa ukwandisa ukusetshenziswa kwama-SCM.
Ukugaya okuluhlaza
Imisebenzi yokugaya izogxila ezigayweni zama-roller eziqondile, ezikwazi ukuzuza ukusebenza kahle kwamandla kakhudlwana, ukukhiqiza okukhulayo nokutholakala okuphezulu.Ukwengeza, amandla okulawula ama-VRM (lapho idrayivu eyinhloko ifakwe i-VFD) aphakeme kakhulu kunezigayo zamabhola noma ngisho nokucindezela kwe-hydraulic roller.Lokhu kuvumela izinga elikhulu lokuthuthukisa, okubuye kwenze ngcono ukuqina kweziko futhi kusize ukwanda kokusetshenziswa kwamanye amafutha kanye nokusetshenziswa kwezinto zokusetshenziswa ezihlukahlukene kakhulu.
I-Pyroprocess
Izinguquko ezinkulu kakhulu esitshalweni zizobonakala kuhhavini.Okokuqala, i-clinker encane izokhiqizwa ngokulingana nokukhiqizwa kukasimende, esikhundleni sobuningi obukhulayo ngama-SCM.Okwesibili, ukwakheka kukaphethiloli kuzoqhubeka nokuvela, kusetshenziswa izimbawula ezithuthukisiwe nobunye ubuchwepheshe bokuvutha ukuze kuqhunyiswe ingxube yamanye amafutha ahlanganisa udoti, i-biomass, amafutha asanda kwakhiwa asuka emfuleni kadoti, ukunothisa komoyampilo (okuthiwa i-oxyfuel). umjovo) ngisho ne-hydrogen.Ukudosa okunembayo kuzonika amandla ukulawula okucophelela kweziko ukuze kukhuliswe ikhwalithi ye-clinker, kuyilapho izixazululo ezifana ne-HOTDISC® Combustion Device zizovumela inhlobo ebanzi yamafutha ukuthi asetshenziswe.Kubalulekile ukuqaphela ukuthi ukushintshwa kukaphethiloli we-fossil okungu-100% kungenzeka ngobuchwepheshe obukhona, kodwa kungase kuthathe elinye ishumi leminyaka noma ngaphezulu ukuze imifudlana yemfucuza ihlangabezane nesidingo.Ukwengeza, imboni kasimende eluhlaza yesikhathi esizayo kuyodingeka icabangele ukuthi lezi zinto ezisetshenziswayo ezihlukile ziluhlaza kangakanani.
Ukushisa okulahlwayo kuzophinde kusetshenziswe, hhayi nje ku-pyroprocess kodwa nakwezinye izindawo zesikhungo, isibonelo ukufaka esikhundleni samajeneretha egesi eshisayo.Ukushisa okulahlwayo okuvela ohlelweni lokukhiqiza ama-clinker kuzobanjwa futhi kusetshenziselwe ukuvala izimfuno zamandla ezisele zesikhungo.
