Crushed - Qhov no Crumbly particulate inorganic khoom

Crushed - ib tug friable particulate inorganic ntaub ntawv los ntawm cov zauv feem loj tshaj 5 hli. Nws yog tsim los ntawm kev sib cais ntawm cov pob zeb, boulders thiab gravel, thaum lub sij hawm ib ncig pob zeb mined los yog rejects, piv txwv li, tsuas tuam txhab uas muag nyob rau hauv cov mineral ua.

Nws yog qhia los ntawm keeb kwm - tej yam ntuj tso thiab unnatural. Ua los ntawm ntau pob zeb, yog li ntawd, yog muab faib ua granite, limestone thiab gravel. Thaum muab faib los ntawm cov chav kawm ntawv ntawm crushed pob zeb, nws yog muab ib lub npav rau tej yam tseem ceeb tshaj yam ntxwv tsis ua li nrug cais. Piv txwv li, nyob rau hauv daim ntawv ntawm rubble pob zeb nws yog kev zoo siab raws li tus kuboobrazny thiab, thiaj hu ua, flakiness. Kuboobrazny rubble muaj siab durability rau puas thiab tej yam, thiab flakiness - kom zoo heev kev twb kev txuas raws li ib tug tub lim. Tab sis nyob rau hauv ceev thiab lub dag lub zog txawj granite version. Nws yog siv raws li ib tug sau ua ib pawg rau ua vaj tse, freight railways, thiab lwm los tsim tej kev loj thiab thiaj li nyob. P. Nyob ntawm lub hom phiaj ntawm qhov kev siv ntawm cov khoom no muaj ntau xav tau nyob rau hauv xws zog raws li hardness, ntim, fractional muaj pes tsawg leeg thiab muaj cov impurities. Granite chippings tau los ntawm ib tug qauv ntawm cov crushing ntuj granite. Nws zoo nkaus li ib qho ntawm feem nrov lub tsev ntaub ntawv, nws tsis yog ua tau tsis muaj tsis muaj siv.

Txawm li cas los, lub Scope ntawm nws siv delimited txhawb tom qab tawg thiab ib tug kuj muaj nqi. Yog hais tias tawg - no granite vaj tse, tus nqi yog tsis txhaum complexity crushing ntawm no cov khoom pob zeb. Yuav kom ua tau ib lub granite yog siv, uas yog tawg rau hauv thooj ntawm ntau ntau thiab tsawg yog 0, 5 mm - granite chips siv nyob rau hauv kev thiab chaw ua si; 5 - 20 mm - lub feem ntau nrov loj ntawm grain. Standard xam tau tias yog feem 20 - 40 mm, nws yog siv rau manufacturing qhob khoom; 20 - 70 mm thiab 40 - 70 mm - ib tug loj feem ntawm nws yog siv rau vaj tse thiab kev tsim kho ntawm cov vaj tse uas loj nws; 70 - 300 mm - Crushed pob zeb siv rau xov tsev basins los yog da. Gravel gravel yog nrov heev nyob rau hauv kev tsim kho kev lag luam raws li qhob sau ua ib pawg thiab qhob khoom.

Nws yog tsim los ntawm sieving cov xuab zeb quarries thiab ntau zoo ib yam li lwm yam - nyob rau hauv lub pob zeb crushing. Kev siv cov no lub tsev cov ntaub ntawv uas muaj peev xwm txo tau tus nqi ntawm qhob, thaum tswj tag nrho nws tus yam ntxwv. Nws yog tsawg tej tshaj granite. Nyob rau hauv tas li ntawd, lub tuam tsev no cov ntaub ntawv uas nyob rau hauv kev siv ntawm txoj kev thiab kev kho raws li lub load rau lub railways. Nyob rau hauv tas li ntawd mus dawb do kis tau nws pab nyob rau hauv toj roob hauv pes tsim - paving, . Tej chaw thiab lwm yam P. Incidentally, rau cov hom phiaj nws tej zaum yuav siv ob qho tib si nyias thiab lub sib tov ntawm gravel thiab xuab zeb. Thaum no txheej tsis yuav tsum tau tseem ceeb cov nqi. Limestone gravel los yog txiv qaub los yog limestone nyob rau hauv sib piv rau tag nrho lwm cov hom yog tshwj xeeb yog yig thiab nrov.

Nws yog muab faib mus rau hauv lub li ib txwm fractions 5 - 20 mm 20 - 40 mm, 4 - 70 mm. Nws muaj calcite, tsim nyob rau hauv yuav tau txais ntawm qhov sib ntxiv ntawm txiv qaub. Cov feem nrov yog xav tau ib feem ntawm 20 - 40 mm. Los ntawm nws yog npaj ib tug substrate rau tso rau sab saum toj ntawm asphalt thiab qhob khoom siv thiab ua.

Muaj xws li ib txoj hauj lwm raws li los ntawm gravel. Tom qab crushing "siv pov tseg", uas cov laus asphalt, cib los yog ua vaj tse, peb tau no sab tsev ntaub.
