Mineral sizersyog hom tshiab crusher uas tau tshwm sim hauv xyoo 1970s, uas tuaj yeem siv los xaiv cov khoom noj los ntawm kev xaiv cov hniav sib txawv thiab kev npaj. Lub tshuab tau nrov nrov hauv kev lag luam thee ntxhua khaub ncaws vim tias nws cov yam ntxwv ntawm kev sib tsoo tsawg dua thiab siab thaiv kev sib sau. Txawm li cas los xij, ntau hom thiab cov ntsiab lus ntawm kev tsim, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej nyuaj feem ntau tshwm sim tag nrho cov kev siv sib txawv. Raws li kev sib piv ntawm ob hom mineral sizers nyob rau tib lub sij hawm ua hauj lwm, daim ntawv no tham txog yuav ua li cas xaiv mineral sizers. Lub peev xwm ua tiav ntawm yangquan tsis muaj . 1 thee npaj cog tom qab kev hloov pauv tau mus txog 7 lab t / a, feem ntau yog ntxuav cov thee nyoos tsis muaj . 3 thiab tsis muaj . 15 thee seams mined hauv mine. Cov txheej txheem ntxuav yog raws li hauv qab no: Cov pob zeb nyoos ntawm ob lub coal seams yog txheeb los ntawm qhov hnyav nruab nrab inclined log cais, thiab qhov kawg ntawm cov thee tsis muaj . 3 thee seam yog txheeb los ntawm jig. Raw thee npaj Rhiav txais lub puab tsaig crusher rau pretreat loj pob thee. Vim tias cov thee nyoos yog qhov tsis yooj yim, cov txiaj ntsig ntawm cov pob zeb tsis tshua muaj. Txhawm rau kom paub qhov txuas ntxiv ntawm tag nrho cov txheej txheem, ib qho siv ib qho standby ob - cov hniav rau cov menyuam crusher yog siv los ua cov pob zeb loj. Lub Hoobkas tau yuav ob hom mineral sizers, tsis muaj . 108 thiab tsis muaj . 107, ua los ntawm cov tuam txhab sib txawv. Tom qab ze li ntawm ob xyoos ntawm kev xyaum ua daim ntawv thov, nws pom tau tias kev xaiv ntawm ob lub cuab yeej yog qhov pib zoo ib yam, tab sis cov nyhuv siv txawv.
1. Ob ob -toothed roller crusher nyob rau hauv lub raw coal rhiav tau siv rau ze li ntawm 2a lub sij hawm, thiab tsis muaj . 108 crusher muaj ntau yam tsis ua hauj lwm, ntau zaus lub reducer puag ntsia hlau loosening, coupling ntsia hlau txiav, txo qhov kub thiab txias, tam sim no hloov amplitude (80 ~ 300a) thiab lwm yam teeb meem, thiab ob lub sij hawm reducer tau raug puas tsuaj. thawb, crushing hniav cov menyuam rhuav cov hniav. Lub iav riser tsis tau nruab rau hauv qhov chaw, thiab kev txhim kho hollow crushing iav nplhaib tseem tawg tiag tiag, thiab nws tsis tshua siv tam sim no. Tam sim no, cov thee nyoos crushing hauv cov khoom siv raw khoom yog tsis muaj . 107, thiab tag nrho cov cuab yeej muaj kev saib xyuas me me, tsis tshua muaj nqi thiab pom tseeb crushing nyhuv. Cov khoom ntawm txoj siv conveyor nyob rau sab sauv thiab qis ntws 105 thiab 201 "Ntawm qhov tsis muaj. 107 crusher tau kuaj nyob rau ntawm qhov chaw, thiab cov kev sib tsoo crushing efficiency nkhaus ntawm qhov tsis muaj . 107 qauv raug soj ntsuam. Nws tuaj yeem pom tau tias qhov tawg thaiv tus nqi hloov pauv ua ntej thiab tom qab cov khoom tawg.
2.Mineral sizers nrog rau kev kawm ntxiv ntawm txoj kev xav ntawm fractional crushing thiab txawv teb tej yam kev mob, cov fractional crushing styles ntawm ob-toothed rollers sib txawv, feem ntau yog reflected nyob rau hauv daim ntawv tsav tsheb, hniav qauv thiab tsis ntawm cov hniav yob. Daim ntawv tsav tsheb: Muaj ib qho tsav thiab tsav ob. Ib qho kev tsav tsheb ib leeg yog ib lub cev muaj zog uas tsav cov hniav yob thiab tsav kev sib hloov ntawm lwm cov hniav yob los ntawm lub iav; ob chav tsav rau ob lub cev muaj zog feem ntau tsav ob cov hniav sib hloov mesh cov khoom siv crushing, thiab kev xaiv ntawm tib lub zog tsav lub zog kuj txawv. Hniav qauv: Muaj ntau hom kev sib tsoo cov hniav, feem ntau muaj cov hniav phaj, hniav hau hom, hniav nplhaib hom, iav hom, hloov tau cov hniav thiab lwm yam. Iav yob tsis: Muaj ntau qhov tsis sib xws ntawm cov iav yob, feem ntau yog txoj kab uas hla ntawm lub iav yob, qhov ntev ntawm lub iav yob, qhov nruab nrab ntawm lub iav yob, qhov ceev ntawm lub iav yob, thiab lwm yam.
Qhov sib sib zog nqus mining ntawm cov thee tau ua rau muaj kev hloov pauv loj hauv qhov chaw ntxhua khaub ncaws. Raw thee pov tseg, pob zeb hardness, bulk particle loj cov ntsiab lus, thiab lwm yam, yog nce, uas maj mam kuaj cov kev ua tau zoo ntawm lub crusher. Yog li ntawd, nws yog ib qho nyuaj los daws cov teeb meem tswv yim hauvmineral sizerstsim raws li ib txwm muaj tswv yim. Nyob rau tib lub sijhawm, thaum qhia cov cuab yeej siv thiab thev naus laus zis txawv teb chaws, nws tsis tuaj yeem ua tes - kuv- nqes, thiab nws yog qhov yuav tsum tau ua ke nrog Tuam Tshoj cov xwm txheej tiag tiag, ntawm - qhov chaw thee zoo, cov thev naus laus zis thev naus laus zis thiab kev siv thev naus laus zis los ua kom tau raws li kev tsim kho kom zoo, thiab cov cuab yeej siv ntau yam khoom siv txawv teb chaws los teeb tsa rau - thaj chaw, uas yuav ua rau muaj teeb meem. Nyob rau hauv kev pom ntawm crushing mob ntawm cov pob zeb loj loj nrog ntau cov av hauv qhov chaw, cov nram qab no yuav tsum tau xav txog hauv kev tsim ntawm crusher.
3.1 Rau cov ntaub ntawv loj, loj yob txoj kab uas hla xaiv tsim lub tswv yim yog saws. Raws li lub hauv paus ntsiab lus ntawm graded crushing, nce txoj kab uas hla thiab nruab nrab ntawm cov hniav yob nyob rau hauv ib tug tsim nyog ntau yam yuav ua rau kom lub meshing lub kaum sab xis, txhim khu lub meshing muaj peev xwm, thiab ua rau kom qhov tshwm sim ntawm ib tug - sij hawm crushing cov ntaub ntawv thiab cov khoom muaj peev xwm dhau mus. Nyob rau tib lub sijhawm, vim qhov txo qis kev sib cuag ntawm cov ntaub ntawv thiab cov hniav sib tsoo, qhov ntau tshaj - crushing raug txo thiab qhov thaiv kev sib sau tau nce. Cov theem disguised tsub kom lub neej ntawm cov hniav yob . 3.2 tsim nyog xaiv hom hniav thiab layout rau cov ntaub ntawv sib txawv ua ntej, vim muaj kev cuam tshuam loj ntawm crushing ntawm cov ntaub ntawv nyuaj, kev ntseeg siab ntawm cov hniav crushing yog feem ntau suav hais tias. Cov hniav tsoos hom hniav hau thiab hniav phaj hom yog qhov nyuaj rau kev hloov mus rau qhov mob no, thiab cov qauv crushing nplhaib yog thawj qhov kev xaiv. Thib ob, nrog kev tshwm sim ntawm cov mines loj, kev ua haujlwm loj yog qhov yuav tsum tau ua tshiab rau lub crusher. Raws li txoj kev xav ntawm graded crushing, qhov ntev ntawm cov hniav yob yog qhov tseem ceeb los xyuas kom meej lub peev xwm ua. Vim qhov kev txwv ntawm kev pub mis, kev xaiv tsim nyog ntawm kev npaj crushing iav tuaj yeem ua tiav qhov kev tsim muaj peev xwm, txwv tsis pub yuav muaj teeb meem xws li cov hniav yob thaiv, kev ua haujlwm tsis txaus thiab kev hnav hauv zos.
Txhawm rau kom ntseeg tau tias cov ntaub ntawv smoothness, ntau qhov kev hloov pauv ntawm qhov loj me yog qhov kev loj hlob ntawm kev sib tsoo crushing, thiab thaj chaw yuav tsum muaj ntau qhov kev hloov pauv ntawm cov khoom siv tuaj yeem hloov mus rau kev hloov pauv sai sai, thiab cov khoom siv nws tus kheej kuj yuav tsum tau hnav cov nyiaj them. Mineral sizers tuaj yeem hloov kho ntau txoj hauv kev. Qhov tseem ceeb tshaj plaws yog los xyuas kom meej qhov kev hloov pauv ntawm cov khoom siv kho, yog li xav tau kev xaiv xaiv.
Cov kev ua haujlwm ntawm cov thee mine yog qhov nyuaj thiab hloov tau, yog li nws yog ib qho tseem ceeb heev uas yuav tsum xaiv cov hniav rau cov pob zeb ntxhia qhov loj ntawm txoj cai raws li kev ua haujlwm ntawm qhov chaw. Kev xaiv cov ntsiab lus ntawm cov tswv yim qee zaum txiav txim siab seb tag nrho cov cuab yeej tuaj yeem daws qhov teeb meem tiag tiag ntawm qhov chaw. Kev siv tswv yim ntawm yangquan no . 1 thee npaj cog ua pov thawj qhov no. Raws li qhov tseeb daim ntawv thov ntawm kev sib piv teb, cov kev xaiv ntawm cov hniav yob, cov hniav zoo thiab layout, particle loj hloov hom thiab lwm yam yuav tsum tau ua tib zoo txiav txim siab nyob rau hauv kev xaiv ntawm tsim.
