Sezvo nyika ichikoshesa kuchengetedzwa kwezvakatipoteredza, semhando yemarara akaoma, mashandisirwo esimbi slag ave nyaya inokosha. Chinyorwa chino chinopa mhinduro yakakwana yehunyanzvi yekudzokorodza simbi slag. Tekinoroji yekugadzirisa yakaoma inofanira kuve nechokwadi chekuti simbi dzinodzoserwa zvakanaka kune rumwe rutivi uye kushandiswa kwakakwana kwemarara kune rumwe rutivi. Matanho anotevera ekugadzirisa simbi slag anotsanangurwa: Kupwanya kwekusarudza; kupatsanurwa kwemagineti uye basa remuchina mutsva une simba rekushandisa simbi slag zvakanyanya; kushandiswa kwemidziyo mitsva kunogona kuderedza zvakanyanya mutengo wekupwanya simbi slag, nokudaro zvichigadzira mabhenefiti akawanda ekushandiswa kwesimbi slag. Kukurudzirwa kwekushandiswa kwakakwana kwesimbi slag kwakagadzira mukana. Kusimudzirwa kwepfungwa iyi yakazara muindasitiri kunoda kushanda pamwe chete kwemakambani anogadzira simbi, nyanzvi dzekugadzirisa zvicherwa nenyanzvi, kushandiswa kwese kwekushandisa, uye madhipatimendi ekushambadzira nekusimudzira.
Mashandisirwo esimbi yesimbi pakuvaka
1) Simbi inoshandiswa kugadzira simende nekongiri. Simbi iyi ine zvicherwa zvinoshanda zvakaita se tricalcium silicate (C3S), dicalcium silicate (C2S) uye iron aluminate ine hunhu hwe hydraulic cementing, zvinoenderana nehunhu hwesimende. Nokudaro, inogona kushandiswa sechinhu chisina kugadzirwa uye semende inoshandiswa kugadzira simende isingatsvedzere, isina simende ye clinker. Simende yesimbi ine hunhu hwakanaka hwakadai sekudzivirira kupera, simba rakawanda re flexural, kuramba ngura uye kuramba chando.
2) Simbi inotsiva matombo akapwanyika nematombo akasanganiswa zvakanaka. Simbi inopwanyika ine mabhenefiti ekuva nesimba guru, nzvimbo isina kusimba, kugara kwenguva refu uye kusakara, vhoriyamu yakakura, kugara zvakanaka, uye kusanganiswa kwakasimba neasphalt. Kana ichienzaniswa nematombo akapwanyika, inodzivirirawo kupwanyika kwekupisa kwakaderera, saka inogona kushandiswa zvakanyanya mukugadzira migwagwa. Simbi inopwanyika, senzira yekufambisa njanji, ine mabhenefiti ekusakanganisa mashandiro enharembozha dzechitima uye kufambisa magetsi zvakanaka. Nekuti simbi inopwanyika zvakanaka uye inoyerera zvakanaka mumvura, zvikamu zvesimende zviri mairi zvinogona kuita kuti iome kuita zvidimbu zvikuru. Simbi inopwanyika yakakodzerawo kuvaka migwagwa mumadhamu nemahombekombe.
Parizvino, nzira inonyanya kushandiswa mukushandisa simbi yemumba ndeyekupwanya simbi kusvika pa -5mm kutsiva jecha remurwizi sechinhu chekuvaka, kana kupwanya simbi yakapwanywa kuita upfu hwakatsetseka kuti ishandiswe sekuwedzera simende. Shandong Huate Magnetoelectric Technology Co., Ltd. yakaitawo tsvakiridzo yakadzama pakushandiswa kwakazara kwesimbi yesimbi, yakashandisa nehunyanzvi chigayo chemagetsi chinodhonza simbi ine simba remagetsi rimwe chete pakupwanya simbi yesimbi, yakavandudza tekinoroji yekugadzirisa simbi yesimbi, uye yakawana mabhenefiti akanaka ehupfumi. Yakashandiswa zvinobudirira muPangang Mining uye mune rimwe bhizinesi resimbi yesimbi yesimbi muLianyungang.
Maitiro ekugadzira simbi yesimbi yechinyakare ndeaya anotevera:
1) Zvidimbu zvikuru zvinopwanywa nejaw crusher kusvika -50, uye simbi yemagineti inoparadzaniswa nepulley yemagineti.
2) Isa saizi yekuparadzanisa simbi kusvika pa +45 mm. Yasara 0-45 mm inowanzo shandiswa senzira yekuvaka migwagwa nezvinhu zvekuzadza. Kuti iwedzere kukosha kwayo, simbi inogona kukamurwa kuita 0-4, 4-8 nedzimwe mhando dzakasiyana. Tekinoroji iyi inoda mari shoma uye mari shoma yekushandisa. Zvisinei, inopfuura 50% yesimbi iri musimbi inenge yakabatana nesimba re -10 mm, saka tekinoroji iyi ichaita kuti simbi irasikirwe zvakanyanya, asi simbi inorema ichawedzera.
Saka, kukuya kwakanyorova kwave kuchishandiswa zvakanyanya kunyanya kune slag inogadzirwa mukugadzira simbi ine Cr, Ni, Mo, nezvimwewo. Maitiro akajairika anosanganisira kupwanya nekukuya kwakatsetseka kwematanho maviri (rod mill/ball mill). Sezvo simbi ine ductility isiri nyore kukuya, kupatsanurwa kwesimbi nesimbi kunogona kuwanikwa nekusiiwa kana kupatsanurwa. Kupfava kwechikamu chemineral cheslag kunowanzova pamusoro pe95% uye pasi pe0.2mm. Mwero wekudzoreredzwa kwesimbi weiyi nzira unodarika 95%, uye goho resimbi inogadzirwa i90 kusvika 92%. Kubva pamaonero ekuparadzanisa simbi neslag, maitiro aya anogona kunzi ndiwo maitiro akanakisa.
Dambudziko guru rekuita izvi nderekuti simbi yakaparadzaniswa ine matope akatsetseka. Nekuti maitiro acho anonyorova, zvakaoma kushandisa mukuvaka. Saka, zvinhu zvakawanda zvesimbi zvinosara mushure mekusarudza simbi zvinoraswa, uye izvi zvinowanzokonzerwa nemutengo wakakwira wekuomesa zvakanyorova uye zvirambidzo zvepamutemo pasi rese. Chero kushandisa kwakakosha kunoda dzimwe nzira dzekurapa matope akanyorova (kuomesa, kukora, nezvimwewo).
Sarudzo inofanira kuitwa pakati pehuwandu hwekudzoserwa kwesimbi kana kuwanikwa kwetsvina yasara. Kazhinji, sarudzo iyi inoenderana nekukosha kwesimbi yadzoserwa.
Maitiro akajairika padanho rino ndeaya anotevera:
Zvidimbu zvikuru zvinopwanywa nejaw crusher kusvika -50, uye simbi yemagineti inoparadzaniswa nepulley yemagineti.
-50 simbi inopwanywa nehammer crusher kana cone crusher, impact crusher, yakasefewa ne multi-layer sesefa, -20-10 grit product inogona kushandiswa sejecha, -10–1 grit product inogona kushandiswa sejecha rakatsetseka.
Tafura I
Kuongororwa kwehukuru hwechimedu che50mm feed muhammer crusher
-10 tsanga yesimbi inokuyiwa muchina wekugadzira bhora wakaoma kuita -200 mesh fine powder, uye magnetic powder dry separator inoshandiswa kubvisa simbi sechinhu chinowedzerwa nesimende.
