Tailings inogadzirwa mubeneficiation process.Nekuda kwegiredhi yakaderera ore, nhamba huru yemaswe inogadzirwa mubeneficiation process, inoverengera ingangoita 90% yeiyo mbishi ore.Huwandu hwemachira muChina hwakakura, uye mazhinji acho haashandiswe zvinobudirira.Anonyanya kuchengetwa mumadhamu emarara kana mumigodhi yemarara, zvichikonzera kutambisa zviwanikwa.Kuunganidzwa kukuru kwemiswe hakungotore zviwanikwa zvevhu chete, asi kunosvibisa nharaunda uye kunokanganisa hutano hwevanhu.Naizvozvo, kushandiswa kwakadzama kwemisara idambudziko rekukurumidza kugadziriswa muindasitiri yemugodhi yeChina.HCMilling(Guilin Hongcheng), semugadziri we tailingsvertical roller chigayo, ichasuma nzira yekugadzira simende clinker kubva kumiswe.

Maminerari makuru ari mu sulphoaluminate simenti clinker ndeye calcium sulphoaluminate uye dicalcium silicate (C2S).Calcium, silica, aluminium uye sulfur mbishi zvinhu zvinodiwa mukugadzirira.Sezvo sulphoaluminate simende clinker ine zvinhu zvakasiyana-siyana uye zvishoma zvinodiwa zvegiredhi, tsvina yakasimba inogona kushandiswa zvakakodzera kutsiva zvimwe zvigadzirwa.Iyo huru yemakemikari zvikamu zvematailings zvinosanganisira SiO2, Fe2O3, Al2O3, CaF2, nezvimwewo, pamwe chete nediki diki reW, Mo, Bi uye zvimwe zvinoteedzera zvinhu.Nemhaka yokuti zvikamu zvemakemikari zvemasikisi zvakafanana nezvigadzirwa zvesilica raw materials inoshandiswa kugadzira sulphoaluminate simenti clinker, tailings inogona kushandiswa kutsiva silica raw materials, iyo isingangochengetedzi zviwanikwa zvevhu, asiwo inodzivirira zvakatipoteredza.CaF2 mu tungsten tailings inonyatsoshanda mineralizer, iyo inogona kukurudzira kuumbwa kwemaminerari akasiyana mu clinker uye kuderedza sintering tembiricha ye clinker.Panguva imwecheteyo, simende clinker inogona kugadzirisa Ti mu titanium gypsum uye W, Mo, Bi uye zvimwe zvinoteedzera zvinhu mu tungsten tailings.Zvimwe zvinhu zvinogona kupinda mucrystal lattice yemaminerari.Nekuti iyo radius yezvinhu zvakapinda zvakasiyana kubva kune ekutanga lattice zvinhu, iyo lattice paramita inoshanduka, zvichikonzera kukanganisa kwelatisi, Inogona kuvandudza basa remaminerari uye kushandura zvimiro zveclinker.

Nzira yekugadzira simende clinker kubva kumiswe: shandisa tailings kutsiva zvachose siliceous mbishi zvinhu zvinoshandiswa mukugadzirwa kwezvakajairwa sulphoaluminate simende clinker, uye zvishoma kutsiva aruminiyamu mbishi zvinhu.Mushure mekugaya kune imwe fineness, dzora kuumbwa kwecement clinker uye C2S zvicherwa kuburikidza nealkalinity coefficient Cm uye sulfur aluminium ratio P, uye gadzira sulphoaluminate simende clinker nealuminium ash, calcium carbide slag, titanium gypsum nezvimwe zvinhu.Matanho aya ndeaya: tailings, aluminium ash, carbide slag uye titanium gypsum zvakateerana pasi kusvika pasi pe200 meshes;Weresa chimwe nechimwe chezvakagadzirwa chiyero maererano nereshiyo yezvakagadzirwa, sanganisa uye kurunga zvakaenzana, dzvanya musanganiswa mukeke rekuyedza nemuchina wepiritsi, woomesa kwe10h ~ 12h pa100 ℃ ~ 105 ℃ yekumira;Iro rakagadzirirwa bvunzo keke rinoiswa muchoto chekushisa chepamusoro, chinopisa kusvika 1260 ℃～1300 ℃, inochengeterwa 40～55min, uye yakadzimwa kusvika kukamuri tembiricha kuti uwane tungsten tailings sulphoaluminate simende clinker.Pakati pavo, kushandiswa kwematailings verticalroller mill yekukuya ndiyo main process step.

HCMilling(Guilin Hongcheng) ndiye anogadzira tailing vertical roller mill.YeduHLM yakatevedzanavertical roller chigayoinogona kukuya 80-600 mesh tailing poda, ichipa yakanaka midziyo tsigiro yenzira yekugadzira simende clinker kubva mukuswe.Kana uine zvinodiwa zvekutenga, ndapota taura neHCM kuti uwane ruzivo rwemidziyo.
