Kukho ubuninzi benkunkuma eyenziwa ngexesha lokuveliswa kwemigodi, ngokukodwa inkunkuma eqinile eveliswa kwiinkqubo zokumbiwa kwemigodi kunye ne-ore dressing, njengamatye e-slag, izinto zodaka, i-coal gangue, njl.
Kangangexesha elide, ubuninzi benkunkuma yeentsinga bufumbe okweentaba. Oku akuhlali nje kuphela kwisixa esikhulu sobutyebi bomhlaba obuxabisekileyo kodwa kubangela ungcoliseko olumandla kwimo engqongileyo. Le nkunkuma ye-tailings iqulethe iintlobo zesinyithi ezinzima kunye nezinto ezinobungozi, ezibeka umngcipheko kwindalo engqongileyo kunye nempilo yabantu.
Umatshini wokwenza izitena zeBrand Wangda: Isixhobo somlingo sokuguqula ukubola sibe sisimangaliso
Umatshini wokwenza izitena we-brand Wangda wamkela itekhnoloji ephezulu kunye neenkqubo kwaye uyilwe ngokukodwa ngokuhambelana neempawu zenkunkuma ezifana nenkunkuma ye-tailings. Iyakwazi ukuguqula inkunkuma ye-tailings ibe yizitena ezikumgangatho ophezulu emva kothotho lonyango.
Inkqubo yokusebenza yomatshini wokwenza izitena we-brand Wangda ikakhulu inamanyathelo amane aphambili: ukulungiswa kwezinto ezikrwada, ukuxuba, ukubumba, kunye ne-sintering.
Ukwenziwa kweMpathi ekrwada: Okokuqala, inkunkuma ye-tailings eqokelelweyo iyajongwa kwaye ityunyuzwe ukususa amaqhekeza amakhulu okungcola kunye nezinto zangaphandle, ukuqinisekisa ukuba ubungakanani bamasuntswana buhlangabezana neemfuno zokusetyenzwa okulandelayo. Emva kokuhluzwa kunye nokutyunyuzwa, inkunkuma ye-tailings ityiswa kwisisele esizinikezeleyo semathiriyeli ekrwada, ilindele inyathelo elilandelayo lokulungisa. [Faka imifanekiso yezixhobo zokulungisa imathiriyeli ekrwada (ezinje ngezityuli kunye nezikrini ezingcangcazelayo) zisebenza]
Ukuxuba: Kwinqanaba lokuxuba, inkunkuma ye-tailings esetyenzisiweyo kunye nesixa esifanelekileyo sezongezo (ezinjengama-binders, njl.) zongezwa kwi-mixer ngokomlinganiselo othile. Ngokuxutywa kwesantya esiphezulu somxube, inkunkuma ye-tailings kunye nezongezo zixutywe ngokupheleleyo kwaye zixutywe ngokulinganayo ukwenza izinto eziluhlaza kwizitena ezingenanto kunye neplastiki elungileyo. [Faka imifanekiso yeencakuba zokuxuba ngaphakathi kwesixhumi esisebenzayo kunye nokuxutywa kwezinto ezikrwada]
Ukubumba: Izinto ezixutywe kakuhle zekrwada zihanjiswa kwi-molding die of the brick-making machine. Umatshini wokwenza izitena zohlobo lweWangda wamkela itekhnoloji yokubumba i-hydraulic ephucukileyo, enokuthi icinezele izixhobo ezikrwada zibe zizitena ezingenanto ezichazayo kunye neemilo ngexesha elifutshane. Izitena ezibunjiweyo ezibunjiweyo zinobuninzi obuphezulu kunye namandla, zibeka isiseko esihle senkqubo ye-sintering elandelayo. [Faka imifanekiso eshukumayo okanye imizobo ecwangcisiweyo yesitena-izitena zokubumba umatshini wokwenza izitena ezingenanto]
Sintering: Emva kokuba izitena ezivaliweyo zenziwe, zondliwa kwindawo yokushisa ephezulu ye-sintering process ye-sintering process. Kwiindawo zokushisa eziphakamileyo zokushisa, ukungcola kweekhemikhali ezahlukeneyo ezinobungozi kwizitena ezivaliweyo zitshiswa, kwaye ekugqibeleni, izitena ezinobunzima obuphezulu ziveliswa. I-kiln ye-sintering ehambelana ngokukodwa nomatshini wokwenza izitena we-brand Wangda yamkela umbane osebenzayo kunye noyilo oluphezulu. Olu luyilo lunokunciphisa ngokufanelekileyo ukusetyenziswa kwamandla kunye nokwandisa ukusebenza kakuhle kwemveliso. [Faka imifanekiso yangaphandle ye-onti yokutshisa kunye nenkqubo yokutshisa izitena ezingenanto ngaphakathi.]
Sintering: Emva kokuba izitena ezivaliweyo zenziwe, zithunyelwa kwindawo yokushisa ephezulu yokutshisa i-sintering. Kwimeko yokudubula kobushushu obuphezulu, ukungcola okwahlukeneyo kweekhemikhali eziyingozi kwizitena ezivaliweyo kutshiswe, kwaye ekugqibeleni, izitena ezinamandla ezinzulu zenziwe. I-kiln sintering elungiselelwe ngokukodwa isitena sophawu lweWangda - umatshini wokwenza umatshini wamkela amandla - okonga kunye noyilo olusebenzayo, olunokunciphisa ngokufanelekileyo ukusetyenziswa kwamandla kunye nokuphucula ukusebenza kakuhle kwemveliso. [Faka imifanekiso yenkangeleko ye-onti etshisayo kunye nenkqubo yokutshisa izitena ezingenanto ngaphakathi]
