Granite yog cov pob zeb intrusive nyob rau hauv cov pob zeb uas tsis muaj zog, muaj cov ntsiab lus quartz siab, feem ntau yog li ntawm 20-50%, thiab qee zaum mus txog 50-60%. Nws yog lub pob zeb uas muaj zog hardness thiab muaj zog abrasiveness, ua rau nws nyuaj rau txheej txheem thiab muab siab xav tau ntawm crushing khoom, tshwj xeeb tshaj yog cov durability ntawm hnav qhov chaw.
Feem ntau, lub ntsiab crushers tuaj yeem xaiv los ua lub puab tsaig crushers (rau thawj crushing), lub khob hliav qab crushers (rau theem nrab thiab theem nrab crushing), thiab ntsug ncej feem crushers (rau xuab zeb ua thiab shaping). Cov crushers sib txawv yog tsim rau ntau theem crushing thiab yuav tsum tau siv ua ke. Rau granite, ib qho nyuaj pob zeb, 2- mus rau 4-theem crushing txheej txheem tuaj yeem saws nyob ntawm seb qhov ntau lawm thiab cov khoom yuav tsum tau ua.
Raws li lub chaw ua haujlwm ncaj qha - ua haujlwm nrog lub hauv paus tsim 42,000 m², DUMA tau tsim tshwj xeeb hauv siab -manganese alloys (xws li Mn18Cr2 thiab Mn22Cr2) thiab cov khoom sib xyaw ua ke- cov ntaub ntawv tiv thaiv kom haum rau siab abrasiveness ntawm granite. Los ntawm cov txheej txheem kev kho cua sov zoo, peb cov khoom siv coj los ua haujlwm zoo heev - muaj peev xwm ua kom tawv nqaij thaum tuav cov khoom siv nrog cov ntsiab lus quartz siab, ua kom muaj kev pab cuam lub neej ntev li 20% -40% thiab txo koj cov nqi khiav lag luam ib tuj.
Ob -theem Crushing: Lub puab tsaig Crusher + Lub khob hliav qab Crusher
Qhov no yog qhov ntau tshaj ob - theem teeb tsa rau granite aggregate kab ntau lawm. Lub puab tsaig crusher yog lub luag haujlwm rau thawj zaug crushing, rhuav tshem cov pob zeb nyoos loj mined los ntawm lub roob mus rau qhov nruab nrab qhov loj (qhov loj me feem ntau nyob ib ncig ntawm 5-30 cm). Lub khob hliav qab crusher ua haujlwm theem nrab thiab zoo crushing. Nrog cov kab noj hniav sib txawv (nqaij, nruab nrab, lossis nplua), nws tuaj yeem tsim ntau yam kev qhia ntawm cov khoom tiav xws li 5-10 hli, 10-20 hli, thiab 20-31.5 hli tom qab kuaj xyuas. Qhov kev teeb tsa no yog qhov yooj yim, txhim khu kev qha, thiab ua haujlwm zoo, ua rau nws muaj txiaj ntsig zoo thiab siv tau zoo rau cov haujlwm me me thiab nruab nrab ntawm granite crushing.
Nyob rau hauv cov nqe lus ntawm hnav qhov chaw, lub puab tsaig daim hlau thiab sab guard daim hlau ntawm lub puab tsaig crusher, raws li zoo raws li lub mantle thiab concave ntawm lub khob hliav qab crusher, yog lub ntsiab consumables. Vim granite lub siab hardness thiab siab quartz ntsiab lus, hnav qhov chaw muaj kev hnav ceev heev. Nws raug nquahu kom ua qhov tseem ceeb rau siab -manganese steel lossis siab -chromium cam khwb cia hlau cov ntaub ntawv, thiab cov khoom siv sib xyaw- cov thev naus laus zis tiv thaiv (xws li cov khoom siv tawv tawv los yog cov tawv tawv tawv) tuaj yeem siv los ua kom ntev lub neej kev pabcuam ntawm cov khoom hnav thiab txo tus nqi hnav ib tuj ntawm cov khoom.
Peb-theem Crushing: Lub puab tsaig Crusher + Lub khob hliav qab Crusher + Vertical Shaft Impact Crusher
Lub tsev nyob rau hauv ob-theem txheej txheem, ib tug ntsug ncej feem crusher (xuab zeb ua tshuab) yog ntxiv los ua ib tug classic peb-theem crushing txheej txheem. Ntawm ib sab, VSI crusher tuaj yeem tsim cov khoom sib sau los ntawm kev tshem tawm cov npoo ntse, ua kom cov duab zoo sib npaug thiab tag nrho, uas ua tau raws li qhov siab - tus qauv yuav tsum tau siv rau hauv siab - qib highways, railways, thiab lwm yam nqi zoo. Ntawm qhov tod tes, nws tuaj yeem tsoo ib feem ntawm cov aggregates, pob zeb hmoov, thiab cov ntaub ntawv ntug rau hauv 0-5 hli tsim cov xuab zeb, ua rau ib txoj kab ntau lawm los tsim cov khoom sib xyaw thiab cov xuab zeb ib txhij.
Hais txog qhov hnav, peb - theem teeb tsa muaj qhov xav tau ntau dua rau kev hnav tsis kam. Ntxiv nrog rau lub puab tsaig crusher lub puab tsaig daim hlau thiab lub khob hliav qab crusher mantle thiab concave, lub rotor, tshuab tuav (los yog ntuav taub hau), cov phaj cuam tshuam, thiab cov phaj tiv thaiv sab hauv ntawm cov ncej ntsug feem crusher yog cov khoom siv tseem ceeb. Lub zog abrasiveness ntawm granite ua rau cov khoom no hnav sai sai. Nws raug nquahu kom siv siab -chromium alloy los yog ceramic composite cov ntaub ntawv rau lub rotor thiab tshuab tuav, thiab siab - hnav-resistant manganese steel los yog imported coj-cov hlau resistant rau daim hlau peripheral guards. Tsim nyog rotor ceev thiab pub tswj yuav tsum tau siv los txo qhov zaus ntawm kev hloov pauv thiab txhim kho tag nrho cov kev khiav hauj lwm ntawm cov kab ntau lawm.
Plaub-theem Crushing: Lub puab tsaig Crusher + Ib zaug -lub tog raj kheej Hydraulic Cone Crusher + Ntau-lub tog raj kheej Hydraulic Cone Crusher + Vertical Shaft Impact Crusher
Plaub-theem crushing txheej txheem tsuas yog siv ob lub khob hliav qab crushers (ib zaug-lub tog raj kheej hydraulic lub khob hliav qab + ntau-lub tog raj kheej hydraulic cone) nyob rau theem nrab thiab theem nrab crushing. Ob lub khob hliav qab crushers ua hauj lwm ua ke los qhia lub crushing siab thiab hnav load, uas ua rau crushing efficiency ntau dua thiab ntau dua ib zaug - tshuab muaj peev xwm. Qhov kev teeb tsa no tshwj xeeb yog tsim rau nruab nrab thiab loj - nplai pob zeb crushing tej yaam num.
Hais txog qhov hnav, plaub- txheej txheem theem muaj qhov zoo meej. Ib qho -lub tog raj kheej thiab ntau- lub tog raj kheej hydraulic lub khob hliav qab tuaj yeem nruab nrog ntau hom kab noj hniav thiab hnav cov khoom siv raws li kev ua haujlwm sib txawv. Pem hauv ntej-theem cone crusher tsom rau kev sib tsoo muaj peev xwm thiab tuaj yeem siv tuab dua -manganese steel mantles thiab concaves; lub nraub qaum-theem tsom rau kev ua kom zoo thiab ua kom zoo thiab tuaj yeem txais siab -chromium lossis ceramic composite hnav qhov chaw. Qhov "gradient noj" txoj hauv kev no ua rau tag nrho cov hnav ib feem ntawm lub neej sib npaug thiab txo tus nqi hnav ib tuj ntawm cov xuab zeb thiab pob zeb. Lub caij no, qhov hnav ntawm cov ncej ntsug feem cuam tshuam crusher ua raws li kev xaiv ib yam li hauv peb- cov txheej txheem theem, tab sis vim muaj ntau yam khoom noj loj, qhov hnav tiag tiag yog me me, txo tus nqi saib xyuas ntxiv.
Ntxiv nrog rau lub ntsiab crushers, ua tiav granite crushing ntau lawm kab kuj yuav tsum tau txhawb cov khoom siv xws li feeders, vibrating screen, thiab siv conveyors los lis cov khoom noj, conveying, thiab tshuaj ntsuam.
Cov saum toj no sawv cev rau kev teeb tsa dav dav rau granite crushing ntau lawm kab. Kev xaiv cov cuab yeej tshwj xeeb thiab hnav cov kev daws teeb meem yuav tsum tau ua kom zoo raws li lub peev xwm ntau lawm, cov yam ntxwv ntawm cov khoom siv raw, thiab cov khoom yuav tsum tau ua. Hauv granite nyuaj pob zeb crushing, kev xaiv thiab kev saib xyuas ntawm cov khoom siv ncaj qha cuam tshuam rau cov nqi tsim khoom thiab sijhawm poob. Nws raug pom zoo kom xav txog tag nrho cov khoom siv, cov qauv, thiab kev yooj yim ntawm kev hloov cov khoom hnav thaum lub sij hawm xaiv cov khoom siv kom ua tiav ntev - lub sij hawm kev lag luam thiab kev ua haujlwm tau zoo.
