Robert Shenk, FLSmidth, inopa tarisiro yekuti 'girinhi' simende zvirimwa zvingaite sei munguva pfupi iri kutevera.
Makumi gumi kubva zvino, indasitiri yesimende ichatotaridzika zvakasiyana zvakanyanya pane zvazvinoita nhasi.Sezvo chokwadi chekuchinja kwemamiriro ekunze chiri kuramba chichiuya kumba, dzvinyiriro yemagariro kune zvinorema emitter ichawedzera uye dzvinyiriro yemari ichatevera, ichimanikidza vanogadzira simende kuita chimwe chinhu.Hapachazove nenguva yekuhwanda kuseri kwezvinangwa kana mepu dzemigwagwa;kushivirira kwenyika yose kuchave kwapera.Indasitiri yesimende ine basa rekutevedzera zvese zvayakavimbisa.
Semutengesi anotungamira kuindasitiri, FLSmidth inonzwa basa iri zvakanyanya.Kambani iyi ine mhinduro dziripo iko zvino, iine zvakawanda mukusimudzira, asi chinokosheswa ndechekuzivisa mhinduro idzi kuvagadziri esimende.Nekuti kana iwe usingakwanise kuona kuti simendi ichataridzika sei - kana iwe usingatendi mazviri - hazvisi kuzoitika.Ichi chinyorwa chitarisiko chesimende chirimwa chenguva pfupi iri kuuya, kubva kugori kuenda kukutumira.Inogona kunge isingaratidzike yakasiyana nechirimwa chaungaona nhasi, asi chakadaro.Musiyano uri munzira iyo inoshandiswa, chii chiri kuiswa mairi, uye imwe yeinotsigira tekinoroji.
Quarry
Nepo shanduko yakazara yekwari isingafanoonekwe munguva pfupi iri kutevera, pachava nemisiyano yakakosha.Kutanga, kuiswa kwemagetsi ekuchera zvinhu uye kutakura - kushandura kubva kudhiziri kuenda kumotokari dzine simba remagetsi mugomba inzira iri nyore yekuderedza kubudiswa kwekabhoni muchikamu chino chesimende.Muchokwadi, chirongwa chechangobva kuitika chekuyedza pane imwe quarry yekuSweden yakaona kudzikiswa kwe98% mukuburitswa kwekabhoni kuburikidza nekushandisa muchina wemagetsi.
Uyezve, iyo quarry inogona kuve nzvimbo yakasurukirwa nekuti mazhinji emotokari dzemagetsi idzi achange achizvitonga zvizere.Kuiswa kwemagetsi uku kunoda mamwe magetsi, asi mumakore gumi anotevera, mamwe mafekitari esimende anotarisirwa kutora masimba ekupa simba rawo nekuvaka kuisirwa nemhepo uye solar panzvimbo.Izvi zvichava nechokwadi chekuti vane simba rakachena ravanoda kuti vagone kugonesa kwete mabasa avo ekwari chete asi kuwedzera magetsi muchirimwa chose.
Kunze kwekunyarara kweinjini dzemagetsi, zvicherwa zvingasaratidzika kunge zvakabatikana sezvakaita mumakore e'peak clinker', nekuda kwekuwedzera kutorwa kwezvinhu zvekuwedzera simende, kusanganisira ivhu rakacherwa, iro richazokurukurwa zvakadzama gare gare muchinyorwa.
Kupwanya
Kupwanya mashandiro achave akangwara uye anoshanda zvakanyanya, kutora mukana weIndasitiri 4.0 tekinoroji kuchengetedza simba uye nekuwedzera kuwanikwa.Michina yekudzidza-inotyairwa yekuona masisitimu inozobatsira kudzivirira kuvharika, nepo kusimbisa kune yakaoma-kupfeka zvikamu uye nyore kugadzirisa kunovimbisa kushoma kuderera.
Stockpile management
Kunyanya kusanganisa kusanganisa kunogonesa hukuru hukuru kudzora makemikari uye kugona kukuya - saka kusimbiswa kwechikamu ichi chechirimwa kuchave kuri kwepamusoro stockpile visualization tekinoroji.Midziyo yacho inogona kutaridzika zvakafanana, asi kutonga kwemhando kuchakwenenzverwa zvakanyanya nekuda kwekushandiswa kwesoftware zvirongwa zvakaita seQCX/BlendExpert™ Pile neMill, izvo zvinobatsira vanogadzira simende kuti vawane kutonga kukuru pamusoro pechigayo chavo chegayo.3D modhi uye nekukurumidza, kunyatsoongorora kunopa nzwisiso huru inogoneka mu stockpile kuumbwa, ichigonesa optimization yekusanganisa nekuita kushoma.Zvese izvi zvinoreva kuti iyo mbishi ichagadzirirwa kuwedzera kushandiswa kweSCMs.
Kukuya mbishi
Raw grinding mashandiro anozotariswa kune vertical roller mill, iyo inokwanisa kuwana hukuru hwesimba, kuwedzera kubereka uye kuwanikwa kwepamusoro.Pamusoro pezvo, kugona kwekutonga kweVRMs (kana iyo main drive ine VFD) yakakura kwazvo kupfuura yebhora zvigayo kana kunyange hydraulic roller press.Izvi zvinogonesa dhigirii yakakura yekugonesa, iyo inovandudza kugadzikana kwechoto uye inobatsira kuwedzera kushandiswa kwemamwe mafuta uye kushandiswa kwezvinhu zvakasiyana siyana.
Pyroprocess
Kuchinja kukuru kune chirimwa kuchaonekwa muchoto.Chekutanga, clinker shoma ichagadzirwa zvinoenderana nekugadzirwa kwesamende, inotsiviwa nekuwedzera huwandu neSCMs.Chechipiri, mafuta ekugadzira acharamba achishanduka, achitora mukana wezvinopisa uye mamwe matekinoroji ekupisa kubatanidza musanganiswa wemamwe mafuta anosanganisira marara, biomass, mafuta achangobva kugadzirwa kubva kunzizi dzemarara, hupfumi hweokisijeni (inonzi oxyfuel. jekiseni) uye kunyange hydrogen.Precision dosing inogonesa kungwarira kwehuni kutonga kuti uwedzere kunaka kweclinker, nepo mhinduro dzakaita seHOTDISC® Combustion Device inogonesa kuwanda kwemafuta kuti ashandiswe.Zvakakosha kucherechedza kuti 100% fossil kutsiva inogoneka nehunyanzvi huripo, asi zvinogona kutora mamwe makore gumi kana kupfuura kuti nzizi dzemarara dziwane kudiwa.Pamusoro pezvo, simende yakasvibirira yeramangwana ichafanirwa kufunga nezvekusvibira kwemamwe mafuta aya.
Kupisa kwemarara kuchashandiswawo, kwete mupyroprocess chete asiwo mune dzimwe nzvimbo dzechirimwa, semuenzaniso kutsiva majenareta egasi rinopisa.Kupisa kwemarara kubva mukugadzira clinker kuchabatwa uye kushandiswa kugadzirisa yasara simba rekuda kwechirimwa.
