Iintsalela zezimbiwa ziveliswa kwinkqubo yoncedo.Ngenxa yomgangatho ophantsi wentsimbi ekrwada, inani elikhulu leentsimbi ziveliswa kwinkqubo yoncedo, libalelwa malunga ne-90% yentsimbi ekrwada.Inani lemisila eTshayina likhulu, kwaye uninzi lwazo alusetyenziswanga ngokufanelekileyo.Zigcinwa ikakhulu kumadama eentsalela zezimbiwa okanye kwimigodi yokulahla inkunkuma, ebangela inkcitho yobutyebi.Ukuqokelelana okukhulu kweentsalela zezimbiwa akuthathi nje kuphela izibonelelo ezininzi zomhlaba, kodwa kungcolisa imo engqongileyo kwaye kuchaphazela impilo yabantu.Ke ngoko, ukusetyenziswa okubanzi kweentsalela zezimbiwa yingxaki engxamisekileyo ekufuneka isombululwe kwishishini lemigodi yaseTshayina.HCMilling(Guilin Hongcheng), njengomvelisi we imisilailitye lokusila elithe nkqo, iya kwazisa indlela yokulungiselela i-cement clinker ukusuka kwii-tailings.
Iiminerali eziphambili kwi-sulphoaluminate cement clinker yi-calcium sulphoaluminate kunye ne-dicalcium silicate (C2S).I-calcium, i-silica, i-aluminiyam kunye ne-sulfure izinto eziluhlaza ziyafuneka kwinkqubo yokulungiselela.Njengoko i-clinker ye-samente ye-sulphoaluminate inoluhlu olubanzi lwezinto kunye neemfuno eziphantsi zebakala, inkunkuma eqinile ingasetyenziselwa ngokufanelekileyo ukubuyisela ezinye izinto eziluhlaza.Iinqununu eziphambili zeekhemikhali ze-tailings ziquka i-SiO2, i-Fe2O3, i-Al2O3, i-CaF2, njl., kunye nenani elincinci le-W, Mo, Bi kunye nezinye izinto zokulandelela.Ngenxa yokuba iikhemikhali ze-tailings ze-tailings zifana neempawu ze-silica ezisetyenziselwa ukulungisa i-samente clinker ye-sulphoaluminate, i-tailings ingasetyenziselwa ukuthatha indawo ye-silica eluhlaza, engagcini nje ukusindisa umhlaba, kodwa ikhusela nokusingqongileyo.I-CaF2 kwi-tungsten tailings yi-mineralizer esebenzayo kakhulu, enokukhuthaza ukubunjwa kwamaminerali ahlukeneyo kwi-clinker kunye nokunciphisa ukushisa kwe-sintering ye-clinker.Ngelo xesha, i-cement clinker inokusombulula i-Ti kwi-titanium gypsum kunye ne-W, i-Mo, i-Bi kunye nezinye izinto zokulandelela kwi-tungsten tailings.Ezinye izinto zinokungena kwi-crystal lattice yeminerali.Ngenxa yokuba i-radius yezinto ezifakiweyo zihluke kwizinto zokuqala ze-lattice, iiparamitha ze-lattice ziya kutshintsha, okubangelwa ukuphazamiseka kwe-lattice, kunokuphucula umsebenzi wamaminerali kunye nokutshintsha iimpawu ze-clinker.
Indlela yokulungisa i-cement clinker ukusuka kwii-tailings: sebenzisa ii-tailings ukuze utshintshe ngokupheleleyo izinto eziluhlaza ze-siliceous ezisetyenziselwa ukuveliswa kwe-clinker ye-samente ye-sulphoaluminate yesiqhelo, kwaye ngokuyinxenye indawo ye-aluminiyam ekrwada.Emva kokugaya kwi-fineness ethile, lawula ukubunjwa kwe-cement clinker kunye ne-C2S minerals ngokusebenzisa i-alkalinity coefficient Cm kunye ne-sulfur aluminium ratio P, kwaye ulungiselele i-sulphoaluminate sement clinker kunye ne-aluminium ash, i-calcium carbide slag, i-titanium gypsum kunye nezinye izithako.Amanyathelo alandelayo: umsila, umlotha we-aluminium, i-carbide slag kunye ne-titanium gypsum ngokulandelanayo phantsi kwee-meshes ezingaphantsi kwama-200;Ukulinganisa icandelo ngalinye lezinto eziluhlaza ngokomlinganiselo wezinto eziluhlaza, xuba kwaye uvuselele ngokulinganayo, cinezela umxube kwikhekhe lovavanyo kunye ne-tablet press, kwaye uyomise i-10h ~ 12h kwi-100 ℃ ~ 105 ℃ yokulinda;Ikeyiki yovavanyo elungisiweyo ifakwa kwiziko lobushushu obuphezulu, ifudunyezwe kwi-1260 ℃~I-1300 ℃, igcinwe kwi-40~I-55min, kwaye yacinywa kwiqondo lokushisa ukuze ufumane i-tungsten tailings sulphoaluminate sement clinker.Phakathi kwabo, ukusetyenziswa komsila nkqoi-roller mill yokugaya inyathelo lenkqubo ephambili.
I-HCMilling(Guilin Hongcheng) ngumvelisi welitye lokusila elithe nkqo.YethuHLM series umsilailitye lokusila elithe nkqoinokugaya i-80-600 ye-mesh tailing powder, inika inkxaso yezixhobo ezilungileyo kwindlela yokulungisa i-cement clinker ukusuka kwi-tailing.Ukuba uneemfuno zokuthenga ezifanelekileyo, nceda uqhagamshelane ne-HCM ngeenkcukacha zesixhobo.
