Izinsalela zikhiqizwa ohlelweni lokuhlomula. Ngenxa yezinga eliphansi le-ore, inani elikhulu lemisila liyakhiqizwa ohlelweni lokuzuza, okubalelwa ku-90% wensimbi eluhlaza. Inani lemisila e-China likhulu, futhi iningi lazo alisetshenziswa ngempumelelo. Ikakhulukazi igcinwe emachibini e-tailings noma ezimayini zokulahla imfucumfucu, okubangela ukumoshwa kwezinsiza. Ukunqwabelana okukhulu kwezinsalela akugcini nje ngokuthatha izinsiza eziningi zomhlaba, kodwa futhi kungcolisa imvelo futhi kuthinte nempilo yabantu. Ngakho-ke, ukusetshenziswa okuphelele kwezinsalela kuyinkinga ephuthumayo okufanele ixazululwe embonini yezimayini yaseShayina. HCMilling(Guilin Hongcheng), njengomkhiqizi we imisilampo roller mill, izokwethula indlela yokulungisa i-cement clinker kusuka kuma-tailings.

Amaminerali amakhulu ku-sulphoaluminatecement clinker yi-calcium sulphoaluminate ne-dicalcium silicate(C2S). I-calcium, i-silica, i-aluminiyamu nesibabule izinto zokusetshenziswa ezisetshenziswayo ziyadingeka ekulungiseni. Njengoba i-clinker kasimende ye-sulphoaluminate inezinhlobonhlobo zezinto zokwakha kanye nezidingo eziphansi zebanga, imfucuza eqinile ingasetshenziswa ngokufanele ukufaka esikhundleni sezinto ezingavuthiwe. Izingxenye zamakhemikhali eziyinhloko ze-tailings zifaka i-SiO2, i-Fe2O3, i-Al2O3, i-CaF2, njll., kanye nenani elincane le-W, i-Mo, i-Bi nezinye izakhi zokulandelela. Ngenxa yokuthi izingxenye zamakhemikhali ze-tailings zifana nezakhiwo ze-silica raw materials ezisetshenziselwa ukulungisa i-sulphoaluminate cement clinker, i-tailings ingasetshenziswa esikhundleni se-silica raw materials, engagcini nje ngokusindisa izinsiza zomhlaba, kodwa futhi ivikela imvelo. I-CaF2 kuma-tungsten tailings iyi-mineralizer esebenza kahle kakhulu, engakhuthaza ukwakheka kwamaminerali ahlukahlukene ku-clinker futhi yehlise izinga lokushisa le-sintering le-clinker. Ngesikhathi esifanayo, i-clinker kasimende ingakwazi ukuxazulula i-Ti ku-titanium gypsum kanye ne-W, Mo, Bi nezinye izakhi zokulandelela ku-tungsten tailings. Ezinye izakhi zingangena ku-crystal lattice yamaminerali. Ngenxa yokuthi i-radius yezinto ezifakiwe ihluke ezintweni zokuqala ze-lattice, imingcele ye-lattice izoshintsha, okuholela ekuhlanekeni kwe-lattice, Ingathuthukisa umsebenzi wamaminerali futhi iguqule izakhiwo ze-clinker.

Indlela yokulungisa i-clinker kasimende kusuka kuma-tailings: sebenzisa i-tailings ukuze ubuyisele ngokuphelele izinto zokusetshenziswa ze-siliceous ezisetshenziswa ekukhiqizeni i-clinker ye-sulphoaluminate ye-cement evamile, bese ubuyisela ingxenye ye-aluminium eluhlaza. Ngemva kokugaya kube ukucoleka okuthile, lawula ukwakheka kwe-cement clinker namaminerali e-C2S ngokusebenzisa i-alkalinity coefficient Cm kanye ne-sulphur aluminium ratio P, futhi ulungise i-sulphoaluminatecement clinker nge-aluminium ash, i-calcium carbide slag, i-titanium gypsum nezinye izithako. Izinyathelo zimi kanje: imisila, umlotha we-aluminium, i-carbide slag kanye ne-titanium gypsum zigaywe ngokulandelana zibe ngaphansi kwamameshe angama-200; Kala ingxenye ngayinye yezinto ezingavuthiwe ngokwesilinganiso sempahla eluhlaza, xuba futhi ugovuze ngokulinganayo, cindezela ingxube ibe ikhekhe lokuhlola ngomshini wethebhulethi, bese uyomisa 10h~12h ku-100℃~105℃ kokubekwe eceleni; Ikhekhe lokuhlola elilungisiwe lifakwa esithandweni sokushisa okuphezulu, sishisiswe ku-1260 ℃～I-1300 ℃, igcinwe ku-40～Imizuzu engu-55, futhi yacinywa ekamelweni lokushisa ukuze kutholwe ama-tungsten tailings sulphoaluminate usimende clinker. Phakathi kwabo, ukusetshenziswa tailings mpoi-roller mill yokugaya iyisinyathelo esiyinhloko senqubo.

I-HCMilling(Guilin Hongcheng) ingumkhiqizi wokugaya umsila oqondile. EyethuUchungechunge lwe-HLM olulandelanayompo roller millingagaya i-80-600 mesh tailing powder, inikeze ukusekela okuhle kwemishini yendlela yokulungisa i-clinker kasimende kusuka ekusikeni. Uma unezidingo zokuthenga ezifanele, sicela uthinte i-HCM ukuze uthole imininingwane yesisetshenziswa.
