Waxtarka kiln-ka simenteedka ayaa muhiim u ah hagaajinta soo saarka clinker-ka oo ku lug leh mabaadi'da thermodynamic iyo foomamka la xidhiidha wareejinta tamarta, falgalka kiimikada, iyo dheellitirka kuleylka. Fikradaha muhiimka ah waxaa ka mid ah yareynta khasaaraha tamarta iyo kordhinta adeegsigii kuleylka si loo hagaajiyo waxtarka gubashada loona yareeyo isticmaalka shidaalka. Halkaan waxaa ku yaal foomam iyo fikrado thermodynamic muhiim ah oo maamula waxtarka kiln-ka simenteedka:
Isku dheelitirka tamarta ee foornooyinka waxaa lagu qori karaa sida:\[Q{\text{ku}} = Q{\text{bax}} + Q_{\text{lumis}}\]Hal:
Hufnaanta gubashada waxaa lagu xisaabiyaa iyadoo lagu saleynayo kuleylka wax ku oolka ah ee la isticmaalo versus kuleylka la bixiyo: \[\eta_{\text{gubashada}} = \frac{\text{Tamarta faa'iidada leh ee soo saarista clinker}}{\text{Tamarta ka jirta shidaalka}} \times 100\]Yaraynta shidaalka aan guban ama hawada xad-dhaafka ah waxa ay ka caawisaa hagaajinta hufnaantan.
Mekaanisyada wareejinta kulaylka (saldhig, wareeg, shucaac) ee foornooyinka iyo kululeeyaha hore ayaa xukuma waxtarka kulaylka. Xeerka Stefan-Boltzmann ee wareejinta kulaylka shucaac wuxuu khuseeyaa:\[Q_{\text{radiation}} = \sigma \cdot A \cdot T^4\]Meesha:
Hagaajinta (T) (yareynta khasaaraha xad-dhaafka ah ee iyada oo loo marayo heerkul sare) iyo dahaadhka saxda ah ayaa lagama maarmaan u ah yareynta (Q_{\text{radiation}}).
Khasaaraha enthalpy-ga ee gaasaska qashinka waa muhiim. Waxa lagu xisaabin karaa iyadoo la isticmaalayo:\[Q_{\text{exhaust}} = \dot{m} \cdot C_p \cdot \Delta T\]Halkey:
Nidaamyada soo kabashada kulaylka qashinka ayaa inta badan la hirgeliyaa si loo yareeyo khasaarahan.
Isticmaalka kulaylka gaarka ah wuxuu cabbiraa tamarta la isticmaalay halkii unug ee clinker-ka la soo saaray: \[H{\text{gaar}} = \frac{Q{\text{totaal}}}{m_{\text{clinker}}}\]Hal:
Hawlgalladu waxay ujeedadoodu tahay in la yareeyo (H_{\text{specific}}) iyadoo la hagaajinayo waxtarka kala goynta kulaylka, hababka hore u kululayn, iyo shidaalka kale.
Falalka kicin (burburinta dhagxaanta lime-ka ilaa lime iyo CO)2), samaynta silikaatka iyo alumiinatooyinka) waxay u baahan tahay tamar kulul oo gaar ah oo ku saleysan enthalpies-ka falcelinta:\[\Delta H{\text{falcelin}} = \sum \Delta H{\text{samaynta}} (\text{alaabooyinka}) – \sum \Delta H{\text{qaab}} (\text{walxaha la falgalaya})\]Xakameynta isku darka alaabta ceeriin iyo heerkulka falcelinta waxay saameyn ku leedahay waxqabadka tamarta.
Waxtarka ayaa la xiriiri karaa soo saarista entropy iyo aan dib loogu laaban karin hababka kulaylka iyo shaqada: \[\Delta S = \frac{Q}{T}\] Yareynta khasaaraha entropy ee gudbinta kulaylka iyo gubashada waxay hagaajineysaa waxtarka guud ee foornooyinka.
Iyadoo la adeegsanayo mabaadi'dan iyo foomamka thermodynamic, warshadaha cementku waxay ujeedadoodu tahay in ay yareeyaan isticmaalka tamarta iyagoo ilaalinaya tayada clinker-ka iyo yaraynta saameynta deegaanka.
Shanghai Zenith Mineral Co., Ltd. waa soo saare hogaaminaya qalabka burburinta iyo hadhka ee Shiinaha. Iyada oo leh in ka badan 30 sano oo khibrad ah warshadaha mashiinada macdanta, Zenith waxay dhistay sumcad xooggan oo ku saabsan keenista burburiyayaal, mills, mashiinnada sameeya ciid, iyo qalabka farsamaynta macdanta tayada sare leh macaamiisha adduunka oo dhan.
Xafiiska dhexe ee Zenith wuxuu ku yaal Shanghai, Shiinaha, wuxuuna isku daraa cilmi-baaris, soo saarid, iib, iyo adeeg, isagoo bixiya xalal dhammeystiran oo loogu talagalay warshadaha uruurinta, macdan qodista, iyo shiididda macdanta. Qalabkeedu si weyn ayaa loogu isticmaalaa metallurgy, dhismaha, injineeriyada kiimikada, iyo ilaalinta deegaanka.
Ku hawlan hal-abuurka iyo qancinta macaamiisha, Shanghai Zenith waxay sii wadaysaa horumarka wax soo saarka caqliga leh iyo soo saarista cagaaran, iyadoo bixineysa qalab la isku halayn karo iyo adeeg ka dib iib oo dhamaystiran si ay macaamiisha u caawiyaan inay gaaraan hawlo waxtar leh oo waara.
