Munguva ichangopfuura, simbi slag poda yekugadzira mutsara nehukuru hukuru hwekugadzira muChina yakapedzwa uye yakaiswa mukushanda muShagang Group.Mari yese yechirongwa ichi ingangoita 170 miriyoni yuan, uye inofungidzirwa kuti 600000 matani esimbi slag poda ichagadzirwa gore rega.Nekuda kwekuoma kwakanyanya kwesimbi slag, iyo dhayamita yeyakajairwa bhora chigayo uye roller chigayo chichiri chinenge 6-8mm mushure mekupwanya, izvo zvinoda kuti mabhizinesi ekugadzira simende agadzirise zvakare.Thesimbi slagvertical roller chigayo inoshandiswa mumutsara wekugadzira wesimbi slag mill yeShagang, iyo yakananga "inosiya" iyo yepakati link.Iyo dhayamita yakatsetseka yesimbi slag inogona kusvika kusvika 0.003mm.Pamusoro pekudzikisa simba rekushandisa kwemaitiro, inogona kuderedza njodzi dzezvakatipoteredza, kuvandudza kukosha kwechigadzirwa, kuwedzera kusimudzira shanduko yesimbi slag kubva ku "marara yakasimba" kuenda ku "chigadzirwa", uye kuwana "kuvandudza kaviri. ” yemabhenefiti ekuchengetedzwa kwezvakatipoteredza uye mabhenefiti ehupfumi.Izvi zvinoratidza kuti chigayo chesimbi chine tarisiro yakanaka yemusika.Senyanzvi yesimbi slag yakatwasuka roller chigayo, HCMilling (Guilin Hongcheng) ichaunza kushandiswa kwemusika kwesimbi slag yakatwasuka roller chigayo.

simbi slag kukuyachigayo

Zvinonzwisiswa kuti "simbi slag grinding" iindasitiri inozivikanwa kuchengetedza nharaunda, chirongwa chehupfumi chinodzokororwa, uye zvakare "yechipiri kusvetuka" kwesimbi slag kurapwa muShagang.Muna 2020, Shagang ichavaka yakakura 3.3 miriyoni matani simbi slag kurapwa chirongwa muChina, uye inowana zana rekushandisa yakazara yesimbi slag kuburikidza nemagineti kupatsanurwa, kupwanya, kukuya tsvimbo, kuongorora uye kumwe kugadzirisa kwakadzika.Pakupera kwaGumiguru wegore rimwe chetero, angangoita mazana matanhatu ematani esimbi slag kubva kuShagang akaiswa zvakabudirira kupurojekiti yekushandura siponji yeZhangjiagang migwagwa yemunisiparati.Mushure mesimbi slag kukuyachigayomutsara wekugadzira unoiswa mukushanda, iyo simbi slag yakanyatso kushanduka kubva ku "marara yakasimba" kuenda ku "chigadzirwa", uye zviwanikwa zvekudzokorora "zvakaomeswa uye zvakasvinwa", zvichiwedzera kuwedzera girini yehupfumi cheni."Dhayamita yezvigadzirwa zvinosvika 6-8mm, tobva tazvikuya nesimbi slag vertical roller mill, uye hunyoro hunosvika 0.003mm muhupamhi."Sekureva kwenyanzvi kubva kumusangano wekushambadzira weShagang New Materials Co., yakajairwa simbi slag yekugadzira mutsara ingangoita 300000 matani muindasitiri yese.Yedu nyowani 600000 tani yekugadzira mutsara ireferensi yeindasitiri yese uye inonyanya kubatsira mukuumbwa kwemaitiro anoshanda eindasitiri.

Tsvagiridzo yekuvandudza uye kushandiswa kwesimbi slag micro poda inyaya inopisa zvichitevera kushandiswa kwakakura kweslag micro powder mumakore achangopfuura.Kugadzirwa kwe micro powder kana composite micro powder nesimbi slag inogona kubvisa mutsauko mukukuya mukugadzirwa kwesimbi slag simenti.Kana simbi slag inogadzika kune imwe fineness nesimbi slag vertical roller chigayo, kana iyo chaiyo nzvimbo yakakura kupfuura 400m2Kg, simbi yesimbi inogona kubviswa kusvika pamwero mukuru.Chimiro chekristaro chechinhu chacho chinorongwazve ne-ultra-fine grinding, uye chidimbu chepamusoro mamiriro ezvinhu anoshanduka, Iyo yepamusoro inogona kuvandudza uye nemichina inomutsa basa resimbi slag, ichipa kutamba kune maitiro e hydraulic cementing zvinhu.Kana simbi slag poda uye slag poda inosanganiswa, ivo vane mukana weiyo superposition.Calcium hydroxide inoumbwa apo C3S neC2S musimbi slag yakanyoroveswa ndiyo inonyanya activator ye slag.Iyo yazvino data inoratidza kuti kunyangwe kushandiswa kweiyo slag poda sekongiri admixture inogona kuvandudza simba rekongiri uye kugadzirisa kushanda uye kusimba kwekongiri musanganiswa, iyo yakaderera alkalinity yekuputika furnace slag (% CaO+% MgO)/(% SiO2+% Al2O3) , inenge 0.9 ~ 1.2, ichaderedza zvakanyanya alkalinity yechikamu chemvura mukrete, inokuvadza passive firimu yekusimbisa mukrete (pH <12.4 iri nyore kukuvadza), uye inokonzera kuora kwekusimbisa mukrete.Pamusoro pezvo, iyo blast furnace slag muviri une vitreous une C3AS uye C2MS2 sezvinhu zvikuru.Iyo gellability ye granulated blast furnace slag poda inobva pakuparara kweiyo slag vitreous chimiro.Hydration zvigadzirwa zvinogona kuumbwa chete pasi pechiito cheCa (OH) 2. Slag yesimbi ine alkalinity yakakwirira (% CaO +% MgO) / (% SiO2), iyo inenge 1.8 ~ 3.0.Zvicherwa zvinonyanya C3S, C2S, CF, C3RS2, RO, etc. Iyo fCaO uye inoshanda zvicherwa musimbi slag inoburitsa Ca (OH) 2 pamusangano wemvura, inovandudza alkalinity yemvura yekongiri system, Inogona kushandiswa se alkaline activator ye slag poda.Iko konkiti yakasanganiswa nesimbi slag powder ine maitiro ekusimba kwepamusoro munguva inotevera.Naizvozvo, simbi slag uye slag composite poda inogona kudzidza kubva kune mumwe nemumwe, uye kuita kwacho kwakanyanya kukwana.

Nzira yekugadzira ye simbi slag vertical roller chigayo inosanganiswa nekupwanya, kugaya, kuomeswa uye kusarudzwa kweupfu, iyo inoratidzirwa nekushandiswa kwesimba shoma, kushanda zvakanaka kwekuvhara, nzvimbo duku yepasi, nzira iri nyore, nezvimwewo. Izvo zvinodiwa fineness uye particle size kugoverwa kunogona kuwanikwa nekugadzirisa kukurumidza kutenderera kwe poda concentrator, mwero wekuyerera kwemhepo yefani yechigayo uye nekukuya.Nekuchinja kwemaitiro ekugadzira uye pfungwa uye kuwedzera kukura muitiro tekinoroji, kudyara kweiyo vertical roller mill system inodzikiswa zvakanyanya, iyo yakaenzana yakaenzana kana kuti yakakwira zvishoma pane iyo yakavharwa yedunhu bhora chigayo system.Nekuda kwemabhenefiti ayo mukuita uye kushandiswa kwesimba, iyo sisitimu ichashandiswa zvakanyanya uye zvakanyanya.HCMilling(Guilin Hongcheng) inyanzvi simbi slag vertical roller chigayo.YeduHLM simbi slagvertical roller chigayo chigayo chakanakira kubatsira vertical roller mill kuwedzera musika wesimbi slag poda.Inogona kukuya simbi slag poda ine yakakwirira chaiyo nzvimbo inopfuura 700, kuchengetedza maitiro maviri ekutanga-kugaya uye kwekupedzisira kugaya, uye kupedzisa kugadzirwa kwesimbi slag poda mune imwe nhanho.

Kana uine zvinodiwa zvinodiwa, tapota taura nesu kuti uwane ruzivo rwemidziyo.
