Limestone crushed pob zeb rau kev tsim kho ua hauj lwm

Limestone gravel siv nyob rau hauv lub xov tej hauj lwm, raws li zoo raws li nyob rau hauv qhuav ntawm mineral chiv thiab txiv qaub. Active khoom ua los ntawm crushing thiab sieving ntxiv pob zeb, uas yog limestone.

piav

Lub kim tshaj plaws thiab lub rubble yog qhov zoo tshaj uas yog tau nyob rau hauv qhov kev ntawm cov pob zeb muaj ib tug calcium carbonate. Ntau yam impurities thiab additives txo qhov zoo thiab cov yam ntxwv ntawm lub limestone pab rubble. Qhov no cov ntaub ntawv uas tsis yog check heev, tab sis zog xws li tus nqi qis, ua hauj te, raws li zoo raws li ib puag ncig muaj kev ruaj ntseg, ua kom nws lub feem ntau kev sib tw cov ntaub ntawv uas rau kev tsim kho ua hauj lwm.

kev yam ntxwv

Limestone gravel muaj zoo heev kuj mus thermal shocks, yus muaj los ntawm zoo zog thiab ua raws li ib tug phooj ywg environmentally khoom. Frost tsis kam thiab dej haum ntawm rubble yog ib theem siab. Yog hais tias tus xov tooj thiab qhov feem pua ntawm impurities yog tsawg tsawg, cov ntaub ntawv uas muaj ib tug reddish xim av los yog daj zas. Thaum piv nrog rau granite, limestone gravel uas muaj tsawg radioactivity thiab siab adhesion. Thaum kawg dolomite yuav tau uas muaj siab zog thiab durability qualities. Heev feem ntau nws yog muab piv nrog rau cov granite rubble thiab txawm nyob rau hauv lub hauv paus ntawm tej ceev. Limestone tsiaj nws muaj tsawg tsawg tej ratio. Qhov no yuav pab kom txo tau nws cov noj. Tus nqi ntawm tej khoom yog qis piv rau zoo xws li cov ntawm lwm hom thiab cov ntaub ntawv.

Ntsiab zog

Limestone gravel muaj ob peb ntau yam. Raws li feem ntau cov kev ua cuboid, flakiness index nws yog tsis pub dhau 10%. Sib tov sib xyaw ntawm tej khoom tshuam devoid ntawm voids, qhov no qhia ib tug uas tsis muaj tus nqi ndlwg ntawm lub phau ntawv tshuaj. Tej ntau yam yog dav siv raws li ib tug hniav pob zeb thaum lub sij hawm qhov kev siv ntawm txoj kev, uas yuav tsis muaj ib tug impressive load. Cov kev ceev ntawm cov ntaub ntawv uas tsis pub tshaj 80 MPa. Nws te kuj yog siab txaus, uas yog vim li cas rubble muaj peev xwm ntawm niaj mus 125 thaw mus thiab khov. Dej haum mas nws txawv ntawm 1 mus rau 2.2%. Yog hais tias peb tham txog wearability, nws yog sib npaug rau cov kev txwv ntawm 0.3-0.8 grams tauj ib square centimeter. Ib qho tseem ceeb zoo yog cov kev nqus, nws yog hom twg los ntawm 1260 mus 1320 kilograms ib cubic Meter.

quarrying

Nyob rau hauv thiaj li yuav tsim rubble limestone rau kev tsim kho, nws yog tsim nyog los tau. Deposits khoom heev heev, qhov no yog vim li cas, nws yog kev lag kev luam zoo kom tau los ntawm cov uas lwm tus quarries. Mining yog nqa tawm los ntawm ib qho qhib, tom qab me me blasting. Thaum lub theem tom ntej, loading pob zeb nrog ib tug excavator, ib tug loj formations nkag mus rau hauv lub crushing tshuab. Ua ke nrog ib tug me me feem sieving mob no tshwm sim los ntawm ib tug tshwj xeeb sab cib. Initial kuaj xyuas thiab sorting rau ntxiv kom tsim nyog cov zauv feem yog siv los ntawm sorting cov ntshav nyob rau hauv lub "roar" yuav pab raws li ib qho piv txwv. Tom qab ntawd, cov ntaub ntawv uas yuav tsum tau, uas tej zaum yuav muaj me me, medium los sis ntxhib feem. Thaum sorting cov niaj hnub cov khoom uas tso cai rau koj txhais tau cov uas duav txhua yam thiab siv.

daim ntawv thov

Nyob rau hauv zus tau tej cov piav cov ntaub ntawv uas yog taw qhia kom paub mus GOST, crushed limestone yuav siv tau rau nqa tawm txawv cov hauj lwm. Thaum nws los txog rau krupnofraktsionnyh hais, lawv yog siv thaum lub sij hawm qhov kev siv ntawm txoj kev. Whereas me me los yog nruab nrab ntau haum rau lub Pov Tseg ntawm lub sab sauv khaubncaws sab nraud povtseg ntawm cov kev los yog cov kev kho kev ua vaj tse khoom. Ua ntej yuav khoom cov ntaub ntawv uas nws yog ib qho tseem ceeb kom koj nrog tus neeg tsim nyog ntawv pov thawj thiab cov kev tswj, uas sau tawm cov zoo cov yam ntxwv thiab kev cia siab ntawm cov khoom. Ua ntej koj yuav tau ib crushed granite, limestone, kws txawj qhia them sai sai rau nws radioactivity. Txawm li cas los, Yog hais tias nyob rau hauv pem hauv ntej ntawm koj high-quality khoom, cov duab yuav tsis tshua muaj neeg uas tsis muaj, qhia tias lub ecology thiab kev nyab xeeb.

Cov kev siv ntawm ntau yam zauv feem ntawm gravel

Crushed limestone (GOST 8267-93) tej zaum yuav muaj ntau feem. Thaum nws los txog rau qhov loj ntawm lub ntsiab los ntawm 5 mus rau 20 millimeters nyob rau hauv pem hauv ntej ntawm koj finely av khoom. Nws yog siv nyob rau hauv qhov siv thiab ua kev ua vaj tse hmoov sib tov. Qhob oversized constructs yog feem ntau manufactured siv no feem limestone gravel. Lug siv cov ntaub ntawv rau lub sab hauv ntawm cov vaj tse, raws li zoo raws li qhov siv ntawm txiv qaub. Crushed uas feem yog hom twg los ntawm 20 mus rau 40 millimeters, yog siv ntau yog muab piv rau lwm yam hom. Raws li lub ntsiab teb ntawm kev siv ntawm cov tom tsim nyob rau hauv dej siab ntawm lub hauv paus, cov lwm yam, nws yuav siv sij hawm txhua yam rau platforms thiab lem, uas tom qab tua tau ib tug presentable tsos thiab ntev khaws nws zoo yam ntxwv. Lub ntsiab kev taw qhia ntawm cov ntaub ntawv uas ua siv thiab ua cov kev reinforced lug thiab kev tsim kho ntawm txoj kev, uas yog nyob rau hauv kev siv yog raug khaus.

Daim ntawv thov krupnofraktsionnogo rubble

Yog hais tias lub ntsiab ntawm cov khoom muaj qhov ntev nyob rau hauv lub chav 40 rau 70 millimeters, nws qhia tau hais tias nws yog siv ncaw. Cov yooj yim kev taw qhia - ib tug ballast txheej ntawm gravel los yog kev kho ntawm tog hauv ncoo. Heev tsis tshua pom thaum cov khoom no yog ib feem siv rau cladding facades. Qhov no tej zaum yuav muaj tseeb tsuas yog rau cov loj tej yaam num.

Yog li, feem ntau nrov yog cov rubble ntawm nruab nrab feem. Nws ua raws li ib tug indispensable tsev ntaub uas muaj zoo heev losis tswvyim dabtsi zog thiab yog ib qho zoo heev muab tub lim. Ntawm nws cov nta peev xwm yuav txawv txias kuj, raws li zoo raws li lub siab tshaj plaws zog uas tso cai rau cov ntaub ntawv uas ua hauj lwm nyob rau hauv ib tug capricious kev nyab xeeb nrog yuav cia li hloov nyob rau hauv kub thiab humidity.

Cons thiab weaknesses

Ua ntej koj yuav rubble limestone M600, koj yuav tsum paub koj tus kheej nrog rau tag nrho cov kev txawj thiab weaknesses ntawm no cov ntaub ntawv uas. Ua ntej ntawm tag nrho cov, nws yuav tsum tau nco ntsoov hais tias hais tias qhov no hom ntawm gravel tsis yog raws li check raws li muab piv rau gravel. Txawm li cas los, nyob rau ntawm no cons xaus. Nyob rau hauv view ntawm kev ruaj ntseg, nws yog ntse siv rau qhov kev siv ntawm ntau yam vaj tse thiab tsev neeg pej xeem lub hom phiaj. Mining yog nqa tawm ntau yooj yim raws li muab piv rau zoo xws li cov ntaub ntawv, nws muaj ib tug zoo ntxim rau cov nqi. Limestone rubble muaj tsawg zog, uas yog vim li cas nws siv nyob rau hauv kev tsim kho ntawm loj chaw yog tsis tsim nyog, uas yog tsis ib txwm yooj yim. Txawm li cas los, nws yog txig qhia nws zoo tshaj plaws ua tau zoo nyob rau hauv zus tau tej cov kev reinforced lug ntawm me me ntau thiab tsawg pab.
