Sezvo nyika inokoshesa kuchengetedzwa kwezvakatipoteredza, semhando yemarara yakasimba, mashandisirwo esimbi slag yava nyaya inokosha.Ichi chinyorwa chinosuma yakazara tekinoroji mhinduro yesimbi slag recycling.Dry processing tekinoroji inofanirwa kuve nechokwadi chekudzoreredza kwesimbi kune rumwe rutivi uye kushandiswa kwakadzama kwemarara kune rimwe divi.Aya anotevera simbi slag kugadzirisa matanho anotsanangurwa: Sarudzo kupwanya;kupatsanurwa kwemagineti uye basa remuchina mutsva-dhiraivha yakakwira-kudzvanya roller mill mukushandiswa kwakazara kwesimbi slag;kushandiswa kwemidziyo mitsva kunogona kuderedza zvakanyanya mutengo wesimbi slag kupwanya, nekudaro kugadzira mabhenefiti akawanda ekushandiswa kwesimbi slag.Kusimudzirwa kwekushandiswa kwakazara kwesimbi slag kwakagadzira mukana.Kusimudzirwa kweiyi pfungwa yakazara muindasitiri kunoda kuedza kwakabatana kwemakambani ekugadzira simbi, nyanzvi dzekugadzira zvicherwa nenyanzvi, kuitwa kwese kwechikumbiro, uye madhipatimendi ekushambadzira nekusimudzira.
Kuvaka kushandiswa kwesimbi slag
1) Simbi slag inoshandiswa kugadzira simende uye kongiri admixtures.Iyo simbi slag ine inoshanda zvicherwa senge tricalcium silicate (C3S), dicalcium silicate (C2S) uye iron aluminate ine hydraulic cementing zvivakwa, izvo zvinoenderana nehunhu hwesimende.Naizvozvo, inogona kushandiswa seyakaomeswa zvinhu uye simende admixture yekugadzira isiri-clinker simende, shoma clinker simende.Simbi slag simende ine hunhu hwakanakisa senge kupfeka kuramba, yakakwira flexural simba, corrosion resistance uye chando kuramba.
2) Simbi slag inotsiva dombo rakapwanyika uye yakaunganidzwa yakanaka.Steel slag yakapwanyika dombo ine zvakanakira simba rakakwirira, rough surface, yakanaka kupfeka kuramba uye kusimba, vhoriyamu hombe, kugadzikana kwakanaka, uye kusanganiswa kwakasimba neasphalt.Kuenzaniswa nedombo rakajairwa rakapwanyika, zvakare inopokana neIyo maitiro ekudzika kwekushisa kwekushisa, saka inogona kushandiswa zvakanyanya mumigwagwa engineering backfill.Steel slag, se njanji ballast, ine hunhu hwekusakanganisa njanji yekufambisa nhare basa uye yakanaka magetsi conductivity.Nekuda kwekuti simbi slag ine mvura yakanaka kupinza uye kudhiraivha, iyo simende zvikamu mairi zvinogona kuomesa kuita zvidimbu zvakakura.Steel slag inokodzerawo kugadzirwa kwemigwagwa mumachakwi nemahombekombe.
Parizvino, iyo inonyanya kushandiswa mudzimba simbi slag nzira ndeyekupwanya simbi slag kusvika -5mm kutsiva rwizi jecha sechinhu chekuvakisa, kana bhora-kugaya yakapwanyika simbi slag kuita hupfu hwakatsetseka kuti hushandiswe sekuwedzera simende.Shandong Huate Magnetoelectric Technology Co., Ltd. yakaitawo tsvakiridzo yakadzama pamusoro pemashandisirwo akazara esimbi slag, nehunyanzvi yakaisa imwe-dhiraivha yepamusoro-inomanikidza roller chigayo pakupwanya kwakanaka kwesimbi slag, yakavandudza simbi slag yekugadzirisa tekinoroji, uye akawana zvakanaka zveupfumi.Yakave yakabudirira kuiswa muPangang Mining uye imwe simbi slag bhizinesi muLianyungang.
Iyo yechinyakare kugadzirwa kwesimbi slag ndeyekutevera:
1) Zvidimbu zvakakura zvakapwanyika nejaw crusher kusvika -50, uye iyo magnetic iron inoparadzaniswa nemagnetic pulley.
2) Isa saizi yekuparadzanisa yesimbi kusvika +45 mm.Iyo yakasara 0-45 mm inowanzoshandiswa sekugadzira mugwagwa uye zvinhu zvekuzadza.Kuti uwedzere kukosha kwayo kwekushandisa, simbi slag inogona kukamurwa kuita 0-4, 4-8 uye mamwe mamakisi akasiyana.Iyo tekinoroji inoda mari shoma uye yakaderera mari yekushandisa.Zvisinei, inopfuura 50% yesimbi yemukati mu slag yakanyanyisa mu -10 mm simba, saka teknolojia iyi ichaita kuti vazhinji varasikirwe nesimbi, asi simbi inorema inowedzera.
Naizvozvo, kunyorova kwakanaka kukuya kwakashandiswa zvakanyanya kunyanya kune slag inogadzirwa mukugadzirwa kwesimbi yepamusoro-yesimbi ine yakakwirira-giredhi Cr, Ni, Mo, etc. Maitiro akajairika anosanganisira kupwanya uye nhanho mbiri kukuya (tsvimbo mill / bhora chigayo. )Sezvo simbi ine ductility isiri nyore kugaya, kupatsanurwa kwesimbi nesimbi slag kunogona kuwanikwa nekusenga kana kurongedza.Iko kunaka kwemaminerari chikamu che slag kazhinji kunopfuura 95% uye pasi pe 0.2mm.Iyo simbi yekudzoreredza mwero weiyi nzira inodarika 95%, uye goho resimbi concentrate inogadzirwa i90 kusvika 92%.Kubva pakuona kwekuparadzanisa simbi uye slag, iyi nzira inogona kunzi ndiyo nzira yakanakisisa.
Iko kusakosha kukuru kweiyi nzira ndeyokuti iyo yakaparadzana simbi slag ndeye yakanaka-grained slurry.Nemhaka yokuti nzira yacho inzira yemvura, zvakaoma kushandisa mukuvaka kwekuvaka.Nokudaro, zvizhinji zvesimbi slag zvinhu zvakasara mushure mekusarudzwa kwesimbi kunoraswa, uye izvi zvinowanzokonzerwa nekudhura kwakanyanya kwekuoma kwemvura uye mitemo yepamutemo pasi rose.Chero chepamusoro kukosha kwekushandisa kunoda dzimwe nzira dzekurapa matope akanyorova (kuomesa, kukora, nezvimwewo).
Sarudzo inofanira kazhinji kuitwa pakati pesimbi yekudzoreredza mwero kana kuwanikwa kweiyo slag yasara.Kazhinji, sarudzo iyi inobva pakukosha kwesimbi yakadzorerwa.
Maitiro akajairika panguva ino ndeaya anotevera:
Zvidimbu zvakakura zvakapwanyika nejaw crusher kusvika -50, uye iyo magnetic iron inoparadzaniswa nemagnetic pulley.
-50 simbi slag inopwanyika nesando crusher kana cone crusher, impact crusher, inopepetwa kuburikidza nemulti-layer sieve, -20-10 grit chigadzirwa chinogona kushandiswa sematombo, -10-1 grit chigadzirwa chinogona kushandiswa sejecha rakanaka.
Tafura I
Ongororo yehukuru hwe 50mm feed mune sando crusher
-10 zviyo simbi slag inokuyiwa kuita bhora rakaoma mu -200 mesh poda yakatsetseka, uyezve electromagnetic yakaoma poda yemagineti separator inoshandiswa kubvisa simbi sekuwedzera simende.
