Raws li kev ua tiav ntawm ntau lub pob zeb txhawm rau tsim cov pob zeb crushed, tau txais cov khoom ntxiv - kev tshuaj ntsuam. Nws yog tsim tom qab sieving lub crushing residues los ntawm tshwj xeeb sieves cais lawv mus rau hauv feem. Qhov tseeb, kev tshem tawm ntawm pob zeb crushed yog nws tus kheej ib feem me me ntawm nws.
Tus yam ntxwv tso tseg
Kev tshuaj ntsuam zoo ib yam hauv lawv cov khoom rau cov khoom siv raw. Zoo li cov pob zeb crushed, nws yog tus cwj pwm los ntawm cov ntsuas xws li qhov ntom ntom, zoo li, lub zog, cov ntsiab lus ntawm cov hmoov av thiab av nplaum. Nws tuaj yeem yog limestone, granite, marble, thiab lwm yam. Cov xim nyob ntawm cov pob zeb uas nws yog cov khoom lag luam: grey, grey-ntsuab, reddish, liab. Kev tshuaj xyuas ntawm cov pob zeb crushed yog muab faib ua feem: qhov tsawg tshaj plaws 1-3 hli, loj txog li 10 hli.
Txawm tias qhov kev tshuaj ntsuam xyuas yog cov khoom lag luam los ntawm kev tsim cov pob zeb crushed, nws tuaj yeem suav tias yog cov khoom siv hauv tsev ywj pheej uas tau siv dav. Tam sim no ntau lub tuam txhab xav tias nws muaj txiaj ntsig ntau dua rau lawv cov kev xav tau los yuav cov tshuaj ntsuam xyuas pob zeb es tsis txhob siv cov xuab zeb kim.
Daim ntawv thov tso tseg
Piv rau cov pob zeb crushed, kev tshuaj ntsuam xyuas yog cov khoom siv pheej yig dua, thiab yog li nws siv tau txo tus nqi ntawm ntau yam kev tsim kho. Nws yog siv rau kev tsim cov pob zeb thiab cov khoom siv ntxiv dag zog, kev tsim khoom ntawm ntau cov ntsiab lus architectural thiab paving slabs. Cov khoom siv loj no yog qhov tsim nyog rau kev teeb tsa ntawm cov tshuab lim dej kom huv los ntawm cov khoom tsis zoo, hauv kev tsim cov asph alt pob zeb sib tov, hauv kev tsim cov phab ntsa zoo nkauj thiab ntau yam khoom tiav.
Sifting granite rubble yog qhov tseem ceeb hauv kev tsim toj roob hauv pes rau dai paj txaj thiab paj txaj, kho kom zoo nkauj vaj thiab chaw ua si. Nws yog xyaum siv pov tseg-dawb ib puag ncig tus phooj ywg khoom. Nws yog feem ntau siv kom tau txais kev zoo nkauj vaj paths, whimsical tsis tsuas yog nyob rau hauv cov duab, tab sis kuj nyob rau hauv cov xim. Los ntawm kev hloov cov kev tshuaj ntsuam ntawm cov xim sib txawv, cov craftsmen tsim tag nrho cov duab nyob rau hauv lub vaj es tsis txhob tho txawv npog ntawm txoj kev thiab platforms. Yog tias cov txheej txheej ntau tau tiv thaiv nrog ciam teb me me, cov khoom siv permeable no yuav tsis raug ntxuav tawm txawm tias los nag hnyav.
Nyob rau lub caij ntuj no, crushed pob zeb sifting yog dav siv rau sprinkling slippery seem ntawm txoj kev nto. Cov qauv, lub ntiajteb txawj nqus tshwj xeeb thiab qhov pom qhov loj me ntawm cov khoom siv no muab cov txiaj ntsig zoo los tiv thaiv plam, ntxiv rau, kev tshuaj xyuas yog ib puag ncig zoo, vim nws tsis muaj tshuaj reagents. Nws raug nqi siv, tshwj xeeb tshaj yog tias cov khoom seem tau sau rau lub caij nplooj ntoo hlav rau lub caij ntuj no tom ntej.
Tus nqi poob qis
Tus nqi ntawm cov khoom lag luam no nyob ntawm ntau yam: qhov kev ncua deb ntawm qhov chaw rho tawm los ntawm qhov chaw, hom thiab hom kev tshuaj ntsuam xyuas, thaj tsam ntawm kev xa khoom, tus nqi thauj khoom, thiab lwm yam. tsim qauv thiab Qhov tseem ceeb tshaj plaws, tsis muaj radionuclides.
Tus nqi qis, lub zog thiab ntau yam ntawm cov khoom lag luam ntawm cov pob zeb no yog qhov zoo tshaj plaws uas ua rau kev tshuaj ntsuam nrov nrov hauv kev tsim kho thiab kev lag luam hauv tsev.
