URobert Shenk, FLSmidth, unika isishwankathelo sokuba izityalo zesamente 'eziluhlaza' zinokujongeka njani kwixesha elizayo elingekude.
Ishumi leminyaka ukusuka ngoku, ishishini lesamente liza kujongeka lahluke kakhulu kunanamhlanje.Njengoko iinyani zokutshintsha kwemozulu ziqhubeka zifika ekhaya, uxinzelelo lwentlalo kwii-emitters ezinzima luya kwanda kwaye uxinzelelo lwezemali luya kulandela, ukunyanzela abavelisi besamente ukuba benze.Akusayi kuphinda kubekho ixesha lokuzifihla emva kweethagethi okanye kwiimephu zendlela;unyamezelo lwehlabathi luya kube luphelile.Ishishini lesamente linoxanduva lokulandela zonke izinto elizithembisileyo.
Njengomthengisi okhokelayo kwishishini, i-FLSmidth iluva olu xanduva ngokunyanisekileyo.Inkampani inezisombululo ezikhoyo ngoku, kunye nophuhliso olungaphezulu, kodwa eyona nto iphambili kukunxibelelana nezi zisombululo kubavelisi besamente.Kuba ukuba awukwazi ukubona ukuba isityalo sesamente siya kujongeka njani - ukuba awukholelwa kuyo - ayizukwenzeka.Eli nqaku liyinkcazo yesityalo sesamente kwixesha elizayo elikufutshane, ukusuka kwi-quarry ukuya kwi-dispatch.Isenokungabonakali yahluke kangako kwisityalo obuya kusibona namhlanje, kodwa injalo.Umahluko kwindlela esebenza ngayo, into efakwa kuyo, kunye nobunye ubuchwepheshe obuxhasayo.
Ikwari
Ngelixa uguqulo olupheleleyo lwekwari lungalindelekanga kwixesha elizayo elingekude, kuya kubakho umahluko ophambili.Okokuqala, ukufakelwa kombane wezinto eziphathekayo kunye nokuthutha - ukutshintshela kwi-diesel ukuya kwizithuthi ezisebenza ngombane kwi-quarry yindlela elula yokunciphisa ukukhutshwa kwekhabhoni kule nxalenye yenkqubo ye-samente.Enyanisweni, iprojekthi yokulinga yakutsha nje kwikwari yase-Sweden ibone ukuncitshiswa kokukhutshwa kwekhabhoni ngama-98% ngokusetyenziswa koomatshini bombane.
Ngaphaya koko, inkwali inokuba yindawo eyedwa kuba uninzi lwezi zithuthi zombane ziya kuba zizimela ngokupheleleyo.Oku kufakelwa kombane kuya kufuna imithombo yombane eyongezelelweyo, kodwa kwishumi leminyaka elizayo, amaziko esamente amaninzi kulindeleke ukuba alawule unikezelo lwazo lwamandla ngokwakha umoya nofakelo lwelanga kwisiza.Oku kuya kuqinisekisa ukuba banawo amandla acocekileyo abawadingayo ukuze banike amandla kungekuphela nje imisebenzi yabo yekwari kodwa bandise ukufakwa kombane kuwo wonke umzi-mveliso.
Ngaphandle kokuzola kweenjini zombane, iikwari zisenokungabonakali zixakeke njengakwiminyaka 'yencopho ye-clinker', ngenxa yokwanda kokuthathwa kwemathiriyeli yesamente eyongezelelweyo, kubandakanywa nodongwe oluyingxolo, ekuza kuxutyushwa ngalo ngokubanzi kamva kwinqaku.
Ukutyumza
Imisebenzi etyumzayo iya kuba krelekrele kwaye isebenze ngakumbi, ithatha ithuba loBuchwephesha be-Industry 4.0 ukugcina amandla kunye nokwandisa ukufumaneka.Iinkqubo zombono eziqhutywa ngoomatshini ziya kunceda ukukhusela izithintelo, ngelixa ugxininiso kwiindawo ezithwele kanzima kunye nokugcinwa lula kuya kuqinisekisa ixesha elincinci lokunciphisa.
Ulawulo lwempahla
Ukudibanisa okusebenzayo ngakumbi kuya kwenza ulawulo lwekhemistri kunye nokusebenza kakuhle kokusila - ngoko ugxininiso kweli candelo lomzimveliso luya kuba kubuchwepheshe obuphezulu bokubonwa kwempahla.Isixhobo sinokujongeka ngokufanayo, kodwa ulawulo lomgangatho luya kucokiswa kakhulu ngenxa yokusetyenziswa kweenkqubo zesoftware ezifana ne-QCX/BlendExpert™ Pile kunye neMill, ezinceda abaqhubi bezityalo zesamente bafumane ulawulo olukhulu kwifidi yabo yokusila ekrwada.Imodeli ye-3D kunye nokukhawuleza, uhlalutyo oluchanekileyo lubonelela ngombono omkhulu onokwenzeka ekuqulunqweni kwempahla, okwenza ukulungelelaniswa kokudibanisa ngomzamo omncinci.Konke oku kuthetha ukuba imathiriyeli ekrwada iya kulungiselelwa ukwandisa ukusetyenziswa kweeSCMs.
Ukusila ekrwada
Imisebenzi yokusila eluhlaza iya kugxininiswa kwii-roller mills ezithe nkqo, ezikwazi ukuphumeza ukusebenza kakuhle kwamandla, ukunyuka kwemveliso kunye nokufumaneka okuphezulu.Ukongeza, amandla okulawula ii-VRMs (xa eyona drive ixhotyiswe ngeVFD) ingaphezulu lee kunezingqusho zebhola okanye ucinezelo lwe-roller olwenziwa ngamanzi.Oku kuvumela iqondo elikhulu lokusebenzela, nto leyo iphucula uzinzo kwiziko kwaye iququzelele ukusetyenziswa okwandisiweyo kwezinye izibaso kunye nokusetyenziswa kwemathiriyeli ekrwada eyohlukeneyo.
I-Pyroprocess
Utshintsho olukhulu kwisityalo luya kubonakala kwi-oven.Okokuqala, i-clinker encinci iya kuveliswa ngokomlinganiselo wemveliso yesamente, endaweni yayo ngemithamo eyandisiweyo yi-SCMs.Okwesibini, i-fuel make-up iya kuqhubeka nokuvela, ithatha ithuba lezitshisi eziphambili kunye nezinye itekhnoloji yokutshisa ukudibanisa umxube wamafutha angamanye aquka iimveliso zenkunkuma, i-biomass, amafutha asandul 'ubunjineli asuka kwimijelo yenkunkuma, ukutyebisa i-oxygen (ebizwa ngokuba yi-oxyfuel). inaliti) kunye ne-hydrogen.Ukuchaneka kwe-dosing kuya kwenza ukuba i-kiln ilawule ngokucokisekileyo ukunyusa umgangatho we-clinker, ngelixa izisombululo ezifana ne-HOTDISC® i-Combustion Device iya kwenza ukuba kusetyenziswe uluhlu olubanzi lwamafutha.Kubalulekile ukuqaphela ukuba i-100% yokutshintshwa kwamafutha efosili kunokwenzeka ngobuchwepheshe obukhoyo, kodwa kungathatha elinye ishumi leminyaka okanye ngaphezulu ukuba imijelo yenkunkuma ifikelele kwimfuno.Ukongeza, umzi-mveliso wesamente oluhlaza wexesha elizayo kuya kufuneka uqwalasele ukuba aluhlaza kangakanani na la mafutha angamanye.
Ubushushu benkunkuma buya kusetyenziswa, kungekuphela nje kwi-pyroprocess kodwa nakwezinye iindawo zomzi-mveliso, umzekelo ukutshintsha iijenereyitha zerhasi eshushu.Ubushushu benkunkuma obusuka kwinkqubo yokuvelisa i-clinker buya kubanjwa kwaye busetyenziselwe ukukhawulelana neemfuno zamandla eziseleyo zomzi-mveliso.
