Nhanganyaya ye clinker ye simende
Simende clinker zvigadzirwa zvakapedzwa zvakavakirwa pa limestone nevhu, zvinhu zvesimbi sezvinhu zvikuru, zvakagadzirwa kuita zvinhu zvitsva zvichienderana nehuwandu hwakakodzera, zvichitsva kusvika chikamu kana zvese zvakanyungudutswa, uye zvinowanikwa mushure mekutonhora. Muindasitiri yesimende, zvikamu zvikuru zvemakemikari zvePortland cement clinker zvinonyanya kushandiswa icalcium oxide, silica uye huwandu hushoma hwealumina ne iron oxide. Muumbirwo mukuru wemineral itricalcium silicate, dicalcium silicate, tricalcium aluminate uye iron aluminate tetracallic acid, Portland cement clinker pamwe nehuwandu hwakakodzera hwegypsum mushure mekukuyiwa hunogona kugadzirwa kuita portland cement.
Kushandisa simende clinker
Parizvino, simende ye clinker inoshandiswa zvakanyanya mumapurojekiti ekuvaka ehurumende nemaindasitiri, akadai sekusimbisa minda yemafuta neminda yegesi, madhamu makuru mumapurojekiti ekuchengetedza mvura, mapurojekiti ekugadzirisa mauto, pamwe nezvinhu zvine acid ne refractory, kupinza mu tunnels pachinzvimbo chegomba. Pamusoro pezvo, huni nesimbi zvinogona kushandiswa pachinzvimbo chehuni kune zvakasiyana-siyana zvakaita sematanda efoni, zvigadziko zvechitima, mapaipi emafuta negesi, uye matangi ekuchengetera mafuta negesi.

Ongororo yemamodheru ekugaya
Chigayo chinotenderera chakamira:
Midziyo mikuru uye zvigadzirwa zvakawanda zvinogona kusangana nekugadzirwa kukuru.Simende yeClinker Milline kugadzikana kwakanyanya. Zvakashata: mari yakawanda yekudyara michina.
Danho rekutanga:Ckumhanya kwezvinhu zvakagadzirwa
Hombe yachosimende clinkerChinhu chinopwanywa ne crusher kusvika chanyatsonaka (15mm-50mm) chinogona kupinda mu grinding mill.
DanhoII: Gkukwenya
Vakapwanyikasimende clinkerZvinhu zvidiki zvinotumirwa kunzvimbo yekuchengetera zvinhu neelevator, uye zvinozotumirwa kuimba yekukuya yemuchina wekugaya zvakaenzana uye nehuwandu nefeeder kuti zvikuyiwe.
Danho rechitatu:Gadzira muzvikamuing
Zvinhu zvakagayiwa zvinoongororwa nehurongwa hwekugadza, uye hupfu husina kukodzera hunoongororwa nechikamu chekuongorora uye hunodzoserwa kumuchina mukuru kuti ugocherwe zvakare.
DanhoV: Ckuunganidzwa kwezvinhu zvakapedzwa
Upfu hunoenderana nekupfava hunoyerera nemupaipi negasi uye hunopinda mumuchina wekuunganidza guruva kuti huparadzaniswe uye huunganidzwe. Upfu hwakapedzwa hunounganidzwa hunotumirwa kunzvimbo yekugadzirwa kwapera nemudziyo wekutakura kuburikidza nechiteshi chekuburitsa, uye hwozoputirwa netangi rehupfu kana otomatiki.
Mienzaniso yekushandiswa kwekugadzira upfu hwesimende hunogadzirwa ne clinker
Muchina wekukuya simende weGuilin Hongcheng wakasimba uye michina nezvigadzirwa zvakanaka kwazvo. Pakati pazvo, pfungwa yekudzivirira zvakatipoteredza inonyanya kuzivikanwa. Guruva rinopfachukira muworkshop yekupwanya idiki kwazvo, nharaunda yese yakachena uye yakarongedzeka, uye kushandiswa kwesimba kwakadererawo. Izvi zvakakosha kumabhizinesi ekugadzira, izvo zvinoderedza zvakananga mari yekugadzira nekushanda uye zvinochengetedza mari yakawanda kumabhizinesi ekupwanya. Saka, iyi igeyo ine mashandiro akanaka kwazvo.
