Crushed limestone yog siv hauv kev ua tiav, nrog rau kev tsim cov ntxhia chiv thiab txiv qaub. Cov khoom no yog tsim los ntawm crushing thiab ntxiv sieving lub pob zeb, uas yog limestone.
Kev piav qhia dav dav
Cov pob zeb uas kim tshaj plaws thiab zoo tshaj plaws yog ib qho uas tau txais hauv cov txheej txheem ua cov pob zeb raws li calcium carbonate. Txhua hom impurities thiab additives txo cov qib zoo thiab cov yam ntxwv tseem ceeb ntawm crushed limestone. Cov khoom no tsis muaj zog heev, tab sis cov khoom xws li tus nqi qis, Frost tsis kam, thiab kev nyab xeeb ib puag ncig ua rau nws cov khoom sib tw tshaj plaws rau kev tsim kho.
Specifications
Limestone crushed pob zeb muaj kev tiv thaiv zoo rau qhov kub thiab txias, muaj zog zoo thiab ua raws li cov khoom siv hauv ib puag ncig. Frost tsis kam thiab dej nqus ntawm cov pob zeb crushed yog nyob rau theem siab. Yog ibtus nqi thiab feem pua ntawm impurities yog me me, ces cov khoom muaj ib tug reddish, xim av los yog daj tint. Yog hais tias peb piv nws nrog granite, ces crushed limestone yog tus cwj pwm los ntawm cov xov tooj cua tsis tshua muaj zog thiab muaj peev xwm ua kom nplaum siab. Thaum kawg, nws muaj peev xwm tau txais dolomite crushed pob zeb, uas muaj cov khoom zoo ntawm lub zog thiab kav ntev. Feem ntau nws yog piv nrog crushed granite kuj raws li lub hauv paus ntsiab lus ntawm bulk ntom. Cov limestone ntau yam muaj qis dua coefficient. Qhov no tso cai rau koj kom txo tau nws cov kev siv. Tus nqi ntawm cov khoom no yog qis dua piv rau cov khoom zoo sib xws ntawm lwm yam tsiaj thiab cov khoom siv.
Basic nta
Crushed limestone muaj ntau ntau yam. Qhov tseem ceeb tshaj plaws yog lub cuboid, nws qhov flakeness Performance index yog nyob rau hauv 10%. Kev sib xyaw ntawm cov khoom siv no yog xyaum tsis muaj voids, uas qhia tau hais tias kev noj tsawg ntawm cov tshuaj binder. Qhov no ntau yam yog dav siv los ua lub ntsej muag pob zeb thaum lub sij hawm kev tsim kho ntawm txoj kev, uas yuav tsis raug rau ib tug impressive load. Qhov ceev ntawm cov khoom tsis tshaj 80 MPa. Nws cov Frost tsis kam yog siab heev, uas yog vim li cas cov pob zeb crushed muaj peev xwm mus txog 125 cycles ntawm defrosting thiab khov. Kev nqus dej sib txawv ntawm 1 txog 2.2%. Yog hais tias peb tham txog abrasion, ces nws yog sib npaug rau qhov txwv ntawm 0.3-0.8 grams ib square centimeter. Ib qho tseem ceeb zoo yog lub ntiajteb txawj nqus, nws txawv ntawm 1260 mus rau1320 kg ib cubic meter.
Quarry mining
Yuav ua kom crushed limestone rau kev tsim kho, nws yuav tsum tau mined. Kev tso nyiaj ntawm cov khoom muaj ntau heev, vim li no nws yog qhov zoo tshaj plaws kom tau txais nws los ntawm cov quarries nyob ze. Mining yog nqa tawm hauv txoj kev qhib, tom qab me me blasting. Nyob rau theem tom ntej, lub pob zeb yog loaded siv lub excavator, thiab loj formations nkag mus rau hauv lub crushing tshuab. Ua ke nrog cov xwm txheej zoo, sifting tshwm sim siv lub sieve tshwj xeeb. Thawj sifting thiab ntxiv sorting rau hauv cov feem tsim nyog yog nqa tawm los ntawm txoj kev sorting units, "Roar" tuaj yeem ua piv txwv. Tom qab ntawd, nws tuaj yeem tau txais cov khoom siv uas yuav muaj qhov zoo, nruab nrab lossis ntxhib feem. Kev txheeb xyuas siv cov cuab yeej siv niaj hnub no uas tso cai rau koj kom tau txais thiab txiav txim siab qhov chaw siv.
Daim ntawv thov
Hauv kev tsim cov khoom siv piav qhia, lawv tau coj los ntawm GOST, crushed limestone tuaj yeem siv rau hauv ntau yam haujlwm. Yog tias peb tab tom tham txog cov ntsiab lus ntxhib-grained, ces lawv tau siv hauv kev tsim txoj kev. Whereas me me los yog nruab nrab yog qhov tsim nyog rau kev sau cov khaubncaws sab nraud povtseg ntawm txoj kev lossis npaj cov khoom siv pob zeb ntxiv. Ua ntej yuav khoom, nws yog ib qho tseem ceeb kom paub koj tus kheej nrog cov ntawv pov thawj thiab cov ntaub ntawv tswj hwm, qhov zooyam ntxwv thiab kev ntseeg siab ntawm cov khoom. Ua ntej yuav granite, limestone crushed pob zeb, cov kws tshaj lij qhia kev saib xyuas nws cov xov tooj cua. Txawm li cas los xij, yog tias koj muaj cov khoom zoo nyob rau hauv pem hauv ntej ntawm koj, qhov taw qhia no yuav qis heev, uas qhia txog kev phooj ywg ib puag ncig thiab kev nyab xeeb.
Siv cov feem sib txawv ntawm cov pob zeb crushed
Crushed limestone (GOST 8267-93) tej zaum yuav muaj feem sib txawv. Yog tias peb tab tom tham txog qhov ntev ntawm cov ntsiab lus los ntawm 5 mus rau 20 millimeters, ces koj muaj cov khoom siv hauv av zoo. Nws yog siv rau hauv kev tsim cov pob zeb sib tov. Reinforced qhob oversized lug feem ntau yog tsim los ntawm cov feem ntawm crushed limestone. Cov ntaub ntawv no yog siv dav hauv cladding ntawm lub tsev, nrog rau kev tsim cov txiv qaub. Crushed pob zeb, feem ntawm qhov sib txawv ntawm 20 mus rau 40 millimeters, feem ntau yog siv piv rau lwm yam. Lub ntsiab cheeb tsam ntawm lub tsheb yog lub ebb ntawm lub hauv paus, thiab lwm yam, nws yog coj mus rau qhov chaw, raws li zoo raws li txoj kev, uas, tom qab solidification, coj nyob rau hauv ib tug presentable tsos thiab khaws lawv zoo yam ntxwv rau ib tug. ntev. Cov kev taw qhia tseem ceeb ntawm kev siv cov khoom siv no yog kev tsim cov pob zeb ua vaj tse thiab kev teeb tsa ntawm txoj kev, uas raug cuam tshuam rau lub sijhawm ua haujlwm.
Siv cov pob zeb ntxhib ntxhib
Yog hais tias cov khoom ntawm cov khoom muaj qhov ntau thiab tsawg ntawm 40 mus rau 70 millimeters, qhov no qhia tau hais tias nws siv tsawg heev. Lub ntsiab kev taw qhia yog lub ballast txheej los yog kev npaj ntawm gravel cushion. Nws yog qhov tsawg heev uas yuav pom thaum cov khoom siv ntawm ib feem yog siv rau facade cladding. Qhov no tsuas yog cuam tshuam rau cov haujlwm loj.
Yog li, pob zeb crushed ntawm nruab nrab feem yog suav hais tias yog qhov nrov tshaj plaws. Nws ua raws li cov khoom siv hauv tsev tsis tseem ceeb, uas muaj cov yam ntxwv zoo sib xws thiab yog qhov muab tub lim zoo heev. Ntawm nws cov yam ntxwv, ib tus tuaj yeem paub qhov txawv ntawm Frost tsis kam, nrog rau lub zog siab tshaj plaws, uas tso cai rau cov khoom siv ua haujlwm hauv kev nyab xeeb nrog kev hloov pauv ntawm qhov kub thiab av noo sai sai.
Cons thiab lub zog
Ua ntej koj yuav crushed limestone M600, koj yuav tsum paub koj tus kheej nrog txhua qhov muaj zog thiab qhov tsis zoo ntawm cov khoom siv no. Ua ntej tshaj plaws, nws yuav tsum nco ntsoov tias hom pob zeb crushed no tsis muaj zog li pob zeb. Txawm li cas los xij, qhov no yog qhov cons xaus. Vim nws tsis muaj teeb meem, nws tau ua tiav siv rau kev tsim kho ntawm ntau qhov chaw thiab cov tsev nyob. Mining yog yooj yim dua piv rau cov ntaub ntawv zoo sib xws, uas muaj txiaj ntsig zoo rau tus nqi. Limestone crushed pob zeb muaj zog tsawg, yog li nws tsis pom zoo siv nws hauv kev tsim cov khoom loj, uas tsis yog ib txwm yooj yim. Txawm li cas los xij, nws ua tau zoo ntawm nws qhov kev ua tau zoo tshaj plaws hauv kev tsim cov pob zeb me me.
