Cov ntaub ntawv tsis yog xim hlau yog cov khoom tseem ceeb hauv kev tsim kho. Xuab zeb, crushed pob zeb yog siv nyob rau hauv zus tau tej cov pob zeb thiab reinforced pob zeb lug, lub tsev sib tov. Cov ntaub ntawv no yog siv rau kev npaj cov hauv paus, kev npaj, ua haujlwm toj roob hauv pes. Hauv kev tsim kho, pob zeb crushed yog siv los ua ib txheej txheej ntawm txoj kev. Qee hom pob zeb crushed yog siv los txhim kho thaj chaw ib puag ncig.

Tom pob zeb thiab xuab zeb

Tag nrho cov khoom siv hauv tsev tau muab cais raws li ob peb lub ntsiab lus:

• origin;
• lub cev thiab txhua yam khoom (qhov ntom, lub zog, Frost tsis kam, nqus dej noo);
• puab thiab qhov loj ntawm cov nplej;
• theem ntawm cov xov tooj cua, muaj cov organic thiab inorganic impurities.

Lub hauv paus chiv keeb ntawm cov pob zeb crushed thiab xuab zeb nyob ntawm cov khoom siv. Muaj cov pob zeb crushed los ntawm cov pob zeb, ore crushed pob zeb, uas yog tsim los ntawm metallurgical recyclable cov ntaub ntawv thiab theem nrab, tau los ntawm crushing siv pov tseg (pob zeb, cib). Lub cev thiab txhua yam khoom ntawm crushed pob zeb ncaj qha nyob ntawm seb cov khoom ntawm nws keeb kwm. Cov ntaub ntawv xav tau tshaj plaws, uas yog raws li pob zeb ntawm siablub zog - resistant rau deformation thiab kev puas tsuaj nyob rau hauv txhua yam kev nyuaj siab. Los ntawm cov nplej loj, pob zeb crushed tau muab faib ua ntau hom: kev tshuaj ntsuam (txog 5 hli), nruab nrab (5-25 hli), loj (25-40 hli).

Xuab zeb los ntawm keeb kwm yog muab faib ua ntuj thiab dag. Tej yam ntuj tso khoom yog tau thaum lub sij hawm kev loj hlob ntawm cov xuab zeb los yog xuab zeb thiab gravel deposits. Nyob ntawm qhov tshwm sim, hiav txwv, dej los yog roob xuab zeb yog qhov txawv. Thawj ob hom yog qhov txawv los ntawm ntau cov nplej sib npaug thiab cov ntsiab lus qis ntawm impurities, piv nrog cov khoom siv mined hauv quarries. Raws li qhov loj ntawm cov granules, xuab zeb muab faib ua ntxhib, nruab nrab thiab nplua.

Natural sand production

Kev tsim khoom ntawm cov khoom siv tsis yog hlau tsis zoo suav nrog ntau theem:

• mining;
• kev ua tiav thiab txhawb nqa (yog tias xav tau);
• khaws cia.

Xyaum txhua yam ntawm cov ntaub ntawv loj yog mined hauv qhov qhib. Quarry xuab zeb yog mined los ntawm excavators los yog bulldozers. Hauv kev tsim cov xuab zeb roob, vim tias muaj ntau cov impurities thiab ntau qhov sib txawv ntawm granules, yuav tsum tau ua ntxiv thiab ntxiv cov khoom siv raw. Cov txheej txheem no muaj xws li ntxuav thiab sorting cov khoom. Rau kev tsim cov feem zoo tshaj plaws siv hauv kev tsim cov khoom sib xyaw ua ke raws li cov cement, ntxiv kev sib tsoo ntawm cov xuab zeb nrog cov menyuam crushers yog ua tau. Ntuj xuab zeb belongs rau cov ntaub ntawv uas muaj feem rau caking, yog li ntawd, nyob rau hauv nws cov ntau lawm, ib tug bunker rau tej ntaub ntawv feem ntau yog siv - ib tug ntaus ntawv.nyob rau hauv daim ntawv ntawm ib tug inverted truncated pyramid rau cia thiab muab khoom ntawm tej raw khoom.

River xuab zeb yog muab rho tawm los ntawm txoj kev hydromechanical hauv reservoir. Cov nkoj nrog hydraulic twj tso kua mis raw khoom los ntawm lub hauv qab ntawm tus dej mus rau ib tug hydraulic pob tseg rau ntawm ntug dej. Cov dej ntws rov qab mus rau hauv tus dej, thaum cov xuab zeb tseem nyob hauv qhov pov tseg. Yog tias qhov chaw hauv qab yog tuab heev, lub thoob of elevator kuj tseem siv.

Kev tsim cov xuab zeb

Qhov chaw faib khoom ntawm cov xuab zeb ntuj tsis sib xws, uas tuaj yeem ua rau muaj qhov tsis txaus ntawm cov khoom no hauv qee thaj tsam. Kev tsim cov xuab zeb dag tuaj yeem daws qhov teeb meem no, muab cov kev xav tau tsim nyog. Artificial bulk khoom yog tau los ntawm crushing hard pob zeb thiab raw cov ntaub ntawv los ntawm lwm qhov chaw. Nyob ntawm cov khoom ntawm lub hauv paus chiv keeb, cov nram qab no hom ntawm cov xuab zeb dag yog txawv:

• Crushed. Siv nyob rau hauv acidic thiab hniav formulations. Ua los ntawm crushing marble, diabase, bas alt los yog ntom metallurgical slags.
• Lub teeb xuab zeb, organic thiab inorganic. Cov khoom siv ntau tau los ntawm pumice, volcanic slag, tuff, kev ua liaj ua teb thiab ntoo pov tseg.
• Sedimentary sands yog qhov tshwm sim ntawm kev sib tsoo pob zeb.
• Ntawm cov xuab zeb, tau los ntawm crushing nthuav av nplaum pob zeb - cov khoom siv hluav taws kub-insulating, muab tub lim rau cov pob zeb sib sib zog nqus thiab mortars.
• Porous slag sands.

Crushed pob zeb ntau lawm

Raw khoom raucrushed pob zeb ntau lawm yog mined nyob rau hauv ib tug qhib txoj kev nyob rau hauv quarries ntawm ntau yam pob zeb. Nyob ntawm tus yam ntxwv ntawm qhov tso nyiaj thiab cov pob zeb rho tawm, cov txheej txheem ntawm kev tsim cov deposits raug xaiv. Rau cov pob zeb nyuaj tshwj xeeb, ua ntej drilling thiab blasting yog nqa tawm. Ib qho nqi yog muab tso rau hauv cov qhov dej ua ntej drilled. Qhov tawg tawg ua rau lub pob zeb tawg, uas raug xa mus rau kev ua haujlwm ntxiv.

Cov ntaub ntawv raw khoom tawm mus rau crushing, uas yog nqa los ntawm crushers ntawm ntau hom (cov menyuam, puab tsaig, cuam tshuam, lub khob hliav qab). Kev xaiv cov txheej txheem yog tsim nyob ntawm seb hom khoom kawg. Tom qab crushing, lub tiav crushed pob zeb yog xa mus rau sorting. Txoj kev tshuaj ntsuam xyuas faib cov khoom mus rau hauv feem raws li cov nplej loj. Lub installation muaj ob peb loj sieves nrog qhov sib txawv diameters. Cov feem me me dhau los ntawm txhua theem ntawm sieves, nyob hauv lub pallet. Nyob rau hauv tus txheej txheem ntawm sorting rau hauv feem, crushed pob zeb yuav tsum tau ntxuav kom tshem tawm cov av nplaum impurities.

Main hom pob zeb crushed pob zeb

Muaj ib pawg loj ntawm cov ntaub ntawv no, tab sis ntawm lawv cov hauv qab no yog cov feem ntau xav tau:

• Granite - lub pob zeb uas ruaj khov tshaj plaws ntawm qhov chaw tsis pom kev. Nws yog tsim los ntawm quartz, mica thiab feldspar. Qhov ntxoov ntxoo tshaj plaws yog liab, liab, grey. Vim nws lub hauv paus chiv keeb, thaum xaiv cov khoom no, tshwj xeeb yuav tsum tau them nyiaj rau daim ntawv pov thawj ntawm radioactivity. Vim yog lub cev thiab cov khoom siv kho tshuab, hom nrov tshaj plaws ntawm cov pob zeb crushed.
• Gravel. Lub hauv paus ntawm cov khoom no yog pob zeb roobyug. Hom pob zeb crushed no yog tsim nyob rau hauv ob txoj kev - crushing pob zeb (txiav gravel) thiab sifting dej los yog hiav txwv av (piv txwv li gravel). Nws yog qhov qis dua hauv lub zog rau granite, tab sis pheej yig dua nrog cov hluav taws xob qis qis.
• Quartzite. Cov khoom siv ntau ntawm cov pob zeb ntawm quartz. Nws tsis yog qis dua rau granite hauv lub zog, tab sis tib lub sijhawm nws muaj me ntsis hluav taws xob tom qab. Vim yog cov qauv qub thiab cov xim zoo nkauj, nws nrov heev hauv kev kho kom zoo nkauj.
• Limestone. Ua los ntawm crushing sedimentary pob zeb. Nyob rau hauv cov nqe lus ntawm lub zog, nws yog inferior rau tag nrho cov lwm hom ntawm crushed pob zeb. Lub hauv paus yog dolomite thiab txiv qaub. Qhov zoo sib txawv - tus nqi qis.

Daim ntawv thov thaj chaw rau cov ntaub ntawv ntau

Kev siv ntau yam ntawm cov ntaub ntawv tsis yog xim hlau yog qhov loj heev, npog yuav luag txhua theem ntawm kev tsim kho thiab yog qhov xav tau hauv lwm hom kev ua haujlwm:

• Npaj pob zeb ntawm ntau qib.
• Kev tsim cov khoom ua vaj tse.
• Kev tsim kho.
• Txoj kev tsheb ciav hlau, txoj kev khiav.
• Landscape design.
• Nyob.
• Cov cuab yeej tiv thaiv txheej ntawm txoj kev hauv qhov dej khov.

Kev thauj khoom ntau

Kev thauj cov ntaub ntawv ntau yog nqa los ntawm kev tsheb ciav hlau (dhau kev deb), kev thauj mus los thiab dej hiav txwv. Rau kev tsheb ciav hlau, tsheb gondola, qhib platforms, tsheb pov tseg yog qhov tsim nyog tshaj plaws - tshwj xeeb cov tsheb gondola nrog rau qhov ua tau ntawm kev siv lub tshuab thauj khoom los ntawmrov qab. Rau kev thauj mus los ntawm cov xuab zeb thiab pob zeb los ntawm txoj kev, cov tsheb thauj khoom pov tseg yog qhov tsim nyog tshaj plaws. Kev xa khoom ntawm cov khoom siv los ntawm cov dej hiav txwv yog qhov kev xaiv kev thauj mus los pheej yig tshaj plaws, tab sis nws muaj feem cuam tshuam tsuas yog nyob ze rau txoj kev hauv dej. Thaum lub sijhawm thauj mus los, tsis pom zoo kom hloov cov ntaub ntawv no mus rau lwm lub tsheb ntawm txoj kev mus rau qhov chaw xa khoom kom tsis txhob poob.

khaws cia thiab muag

Tom qab mining thiab, yog tias tsim nyog, ntxiv dag zog, crushed pob zeb nyob rau hauv daim ntawv uas tus neeg siv pom nws yog xa mus rau lub warehouse. Txhua hom thiab feem ntau muaj pes tsawg leeg ntawm cov khoom loj yog khaws cia nyias. Cov chaw khaws cia yuav tsum yog theem thiab yuav tsum tsis txhob sau cov dej nag. Yog tias tsim nyog, ntxiv kev tiv thaiv dej hauv av yog tsim. Thaum lub caij ntuj no, cov ntaub ntawv raug tshem tawm ntawm cov daus thiab dej khov.

Kev xa cov khoom tsis yog hlau los ntawm qhov chaw cia yog feem ntau nqa los ntawm txoj kev. Kev zam yog cov lag luam loj nrog cov kab tsheb ciav hlau sib cais. Rau kev nyab xeeb thiab yooj yim xa khoom ntawm cov khoom siv rau cov neeg siv kawg, qhov chaw cia khoom yog nruab nrog txoj kev yooj yim nkag. Feem ntau ib-txoj kev nplhaib tsheb khiav yog npaj. Rau kev yooj yim ntawm kev thauj khoom thiab kev tiv thaiv ntawm caking, ib lub bunker rau cov ntaub ntawv loj yog siv. Teeb pom kev zoo yog muab rau kev ua haujlwm hmo ntuj.
