Robert Shenk, FLSmidth, akupereka chithunzithunzi cha zomera za simenti 'zobiriwira' zomwe zingawonekere posachedwa.
Zaka khumi kuchokera pano, makampani a simenti adzawoneka kale mosiyana kwambiri ndi momwe amachitira lero.Pamene zenizeni za kusintha kwa nyengo zikupitirirabe, kukakamizidwa kwa anthu kwa anthu otulutsa mpweya wambiri kudzawonjezeka ndipo mavuto azachuma adzatsatira, kukakamiza opanga simenti kuchitapo kanthu.Sipadzakhalanso nthawi yobisala kumbuyo kwa zolinga kapena mapu amisewu;kulolerana kwapadziko lonse kudzakhala kutatha.Makampani a simenti ali ndi udindo wotsatira zonse zomwe adalonjeza.
Monga ogulitsa otsogola kumakampani, FLSmidth imamva bwino udindowu.Kampaniyo ili ndi mayankho omwe alipo tsopano, ndi zina zambiri zomwe zikukula, koma chofunika kwambiri ndikudziwitsa anthu opanga simenti.Chifukwa ngati simungathe kuwona momwe chomera cha simenti chidzawoneka - ngati simukhulupirira - sichingachitike.Nkhaniyi ndi chithunzithunzi cha chomera cha simenti cha posachedwapa, kuchokera ku miyala mpaka kutumiza.Zingawoneke zosiyana kwambiri ndi zomera zomwe mungawone lero, koma ziri.Kusiyana kwake ndi momwe zimagwiritsidwira ntchito, zomwe zikuyikidwamo, ndi zina zamakono zothandizira.
Quarry
Ngakhale kusinthika kwathunthu kwa miyalayi sikunawonekere posachedwa, padzakhala kusiyana kwakukulu.Choyamba, magetsi opangira zinthu ndi zoyendetsa - kusintha kuchokera ku dizilo kupita ku magalimoto oyendetsa magetsi m'mabowo ndi njira yosavuta yochepetsera mpweya wa carbon mu gawo ili la ndondomeko ya simenti.M'malo mwake, pulojekiti yoyeserera yaposachedwa pa malo osungiramo miyala ku Sweden idachepetsa 98% ya mpweya wotulutsa mpweya pogwiritsa ntchito makina amagetsi.
Kuonjezera apo, malo osungiramo miyala amatha kukhala osungulumwa chifukwa ambiri mwa magalimoto amagetsiwa adzakhalanso odzilamulira okha.Kuyika magetsi kumeneku kudzafuna magwero owonjezera a magetsi, koma m'zaka khumi zikubwerazi, mafakitale ambiri a simenti akuyembekezeka kuwongolera mphamvu zawo pomanga zida zamphepo ndi dzuwa pamalopo.Izi ziwonetsetsa kuti ali ndi mphamvu zoyera zomwe angafunikire kuti aziyendetsa osati ntchito zawo zokha, komanso kuwonjezera magetsi pamalo onse.
Kupatulapo kukhala chete kwa injini zamagetsi, miyala yamtengo wapatali sangawoneke ngati yotanganidwa monga zaka za 'peak clinker', chifukwa cha kuchuluka kwa zinthu zowonjezera cementitious, kuphatikizapo dongo lopangidwa ndi calcined, lomwe liyenera kukambidwa mwatsatanetsatane pambuyo pake m'nkhaniyo.
Kuphwanya
Ntchito zophwanyidwa zidzakhala zanzeru komanso zogwira mtima kwambiri, kutengera mwayi paukadaulo wa Industry 4.0 kusunga mphamvu ndikukulitsa kupezeka.Makina owonera masomphenya oyendetsedwa ndi makina amathandizira kuletsa kutsekeka, pomwe kutsindika pazigawo zolimba komanso kukonza kosavuta kudzatsimikizira kuti nthawi yocheperako.
Kasamalidwe ka katundu
Kuphatikizana koyenera kumathandizira kuwongolera bwino kwa chemistry ndi kugaya bwino - kotero kugogomezera gawo ili la mbewuyo kudzakhala paukadaulo wapamwamba wowonera masheya.Zida zitha kuwoneka chimodzimodzi, koma kuwongolera kwabwino kudzayengedwa bwino kwambiri chifukwa chogwiritsa ntchito mapulogalamu apulogalamu monga QCX/BlendExpert™ Mulu ndi Mill, omwe amathandiza oyendetsa mafakitale a simenti kukhala ndi mphamvu pazakudya zawo zosaphika.Kujambula kwa 3D komanso kusanthula kwachangu, kolondola kumapereka chidziwitso chambiri chotheka pakupanga masheya, ndikupangitsa kukhathamiritsa kwa kusakanikirana ndikuyesa kochepa.Zonsezi zikutanthauza kuti zopangirazo zidzakonzekera kukulitsa kugwiritsa ntchito ma SCM.
Yaiwisi akupera
Ntchito zogaya zaiwisi zidzayang'ana pa mphero zodzigudubuza, zomwe zimatha kupeza mphamvu zowonjezera mphamvu, zowonjezera zokolola komanso kupezeka kwakukulu.Kuphatikiza apo, kuthekera kowongolera ma VRM (pamene choyendetsa chachikulu chili ndi VFD) ndichopambana kwambiri kuposa mphero za mpira kapena makina osindikizira a hydraulic roller.Izi zimathandizira kukhathamiritsa kwakukulu, komwe kumapangitsa kuti ng'anjo ikhale yokhazikika komanso kumathandizira kugwiritsa ntchito mafuta ena komanso kugwiritsa ntchito zinthu zosiyanasiyana.
Pyroprocess
Kusintha kwakukulu kwa zomera kudzawoneka mu ng'anjo.Choyamba, ma clinker ochepa adzapangidwa molingana ndi kupanga simenti, kusinthidwa ndi kuchuluka kwa ma SCM.Kachiwiri, mafuta opangira mafuta apitiliza kusinthika, kutengera mwayi wowotcha wapamwamba kwambiri ndi matekinoloje ena oyatsira moto kuti aziphatikiza mafuta osakanikirana, kuphatikiza zinyalala, biomass, mafuta ongopangidwa kumene kuchokera ku zinyalala, kulimbikitsa mpweya (otchedwa oxyfuel). jekeseni) komanso ngakhale haidrojeni.Kuwongolera kolondola kudzathandiza kuwongolera mosamala ng'anjo kuti kukulitsa mtundu wa clinker, pomwe mayankho ngati HOTDISC® Combustion Device amathandizira kuti mafuta ambiri agwiritsidwe ntchito.Ndikoyenera kudziwa kuti 100% mafuta opangira mafuta ndi kotheka ndi matekinoloje omwe alipo kale, koma zingatenge zaka khumi kapena kuposerapo kuti mitsinje ya zinyalala ikwaniritse zofunikira.Kuphatikiza apo, chomera cha simenti chobiriwira chamtsogolo chiyenera kuganizira momwe mafuta ena amakhalira obiriwira.
Kutentha kwa zinyalala kudzagwiritsidwanso ntchito, osati mu pyroprocess komanso m'madera ena a fakitale, mwachitsanzo kusintha majenereta a gasi otentha.Kutentha kwa zinyalala kuchokera ku njira yopangira clinker kudzalandidwa ndikugwiritsidwa ntchito kuthetsera mphamvu zotsalira za mbewuyo.
