Isingeniso ku-clinker yesimende
I-cement clinker yimikhiqizo eqediwe kancane esekelwe ku-limestone nobumba, izinto zokusetshenziswa zensimbi njengezinto zokusetshenziswa eziyinhloko, ezakhiwe zibe izinto zokusetshenziswa ngokwesilinganiso esifanele, zishiswe kuze kube yilapho ingxenye noma yonke into encibilikisiwe incibilikisiwe, futhi itholakale ngemva kokupholisa. Embonini ye-cement, izingxenye zamakhemikhali eziyinhloko ze-Portland cement clinker esetshenziswa kakhulu yi-calcium oxide, i-silica kanye namanani amancane e-alumina kanye ne-iron oxide. Ukwakheka okuyinhloko kwamaminerali yi-tricalcium silicate, i-dicalcium silicate, i-tricalcium aluminate kanye ne-iron aluminate i-tetracallic acid, i-Portland cement clinker kanye nenani elifanele le-gypsum ngemva kokugaya kungenziwa kube yi-portland cement.
Ukusetshenziswa kwe-clinker yesimende
Njengamanje, i-cement clinker isetshenziswa kabanzi kumaphrojekthi okwakha ezimbonini, njengokufaka usimende ezindaweni zikawoyela kanye nezindawo zegesi, amadamu amakhulu kumaphrojekthi okulondoloza amanzi, amaphrojekthi okulungisa amasosha, kanye nezinto ezi-acid kanye ne-refractory, ukufakwa kwe-tunnels cap esikhundleni se-pit. Ngaphezu kwalokho, izinkuni nensimbi kungasetshenziswa esikhundleni sezinkuni ezinhlobonhlobo zezicelo ezifana nezigxobo zocingo, izitulo zesitimela, amapayipi kawoyela negesi, kanye namathangi okugcina uwoyela kanye negesi.
Ukugeleza kwenqubo yokugaya i-clinker yesimende
Ishidi lokuhlaziya izithako eziyinhloko ze-simende clinker (%)
| I-CaO | I-SiO2 | Fe2O3 | Al2O3 |
| 62%-67% | 20%-24% | 2.5%-6.0% | 4%-7% |
Uhlelo lokukhetha imodeli yomshini wokwenza i-cement clinker powder
| Imininingwane | 220-260㎡/kg(R0.08≤15%) |
| Uhlelo lokukhetha imishini | Umshini wokugaya oqondile |
Ukuhlaziywa kwamamodeli okugaya
Umshini wokugaya oqondile:
Imishini emikhulu kanye nomkhiqizo ophezulu kungahlangabezana nokukhiqizwa okukhulu.Isigayo se-Clinker sikasimendeinokuqina okuphezulu. Okubi: izindleko eziphezulu zokutshalwa kwezimali kwemishini.
Isigaba I:Cukushesha kwezinto zokusetshenziswa
Inkului-clinker yesimendeIzinto ezisetshenziswayo zichotshozwa yi-crusher kuze kube yilapho zinobuncane bokuphakela (15mm-50mm) obungangena emshinini wokugaya.
IsitejiII: Gukugoqa
Abachotshoziwei-clinker yesimendeIzinto ezincane zithunyelwa endaweni yokugcina izinto nge-lifti, bese zithunyelwa ekamelweni lokugaya lesitsha ngokulinganayo nangobuningi yi-feeder ukuze zigaywe.
Isigaba III:Hlela ngezigabaing
Izinto ezigayiwe zilinganiswa ngohlelo lokulinganisa, kanti impuphu engafaneleki ilinganiswa ngohlelo lokuhlukanisa bese ibuyiselwa emshinini oyinhloko ukuze igaywe kabusha.
IsitejiV: Cukuqoqwa kwemikhiqizo eqediwe
Impuphu evumelana nobuncane igeleza ngepayipi kanye negesi bese ingena eqoqweni lokuqoqa uthuli ukuze ihlukaniswe futhi iqoqwe. Impuphu eqoqwe ithunyelwa esigungwini somkhiqizo oqediwe ngedivayisi yokudlulisa ngembobo yokukhipha, bese ipakishwa yithangi lempuphu noma i-automatic packer.
Izibonelo zokusetshenziswa kokucubungula i-cement clinker powder
Umshini wokugaya we-clinker we-cement kaGuilin Hongcheng uqinile futhi imishini nemikhiqizo mihle kakhulu. Phakathi kwayo, umqondo wokuvikelwa kwemvelo uvelele kakhulu. Ukugcwala kothuli endaweni yokusebenzela yokugaya kuncane kakhulu, indawo yonke ihlanzekile futhi icocekile, futhi ukusetshenziswa kwamandla nakho kuphansi kakhulu. Lokhu kubaluleke kakhulu kumabhizinisi okukhiqiza, okunciphisa ngqo izindleko zokukhiqiza nokusebenza futhi konga izindleko eziningi zamabhizinisi okugaya. Ngakho-ke, lesi isigayo esisebenza kahle kakhulu.
