Nruam nruas sib xyaw cog yog cov khoom siv sib xyaw ua haujlwm uas tsim cov khoom sib xyaw asphalt hauv hom nruas nruam, cov nroj tsuag no tuaj yeem muab faib ua asphalt nruas mix nroj tsuag thiab counter flow asphalt mixing nroj tsuag. Ob qho tib si ntawm cov chaw tsim khoom siv kub sib xyaw asphalt hauv kev ua haujlwm tas mus li. Kev sib sau ua ke cua sov, ziab thiab cov khoom sib xyaw ntawm ob hom asphalt nroj tsuag yog tag nrho ua tiav hauv lub nruas.

Nruam sib xyaw cov nroj tsuag (nruas Mix Plant thiab nruam sib xyaw cog) feem ntau yog siv hauv kev tsim kho vaj tse, dej thiab hluav taws xob, chaw nres nkoj, wharf, txoj kev loj, railway, tshav dav hlau, thiab lub tsev choj, thiab lwm yam. Nws muaj cov khoom siv txias txias, lub tshuab hluav taws xob sib txuas, lub tshuab ziab khaub ncaws, kev sib xyaw ua ke, cov dej plua plav, cov khoom siv asphalt, thiab hluav taws xob tswj qhov system.



Qhov zoo sib xws ntawm nruas asphalt nroj tsuag thiab counter flow asphalt nroj tsuag
Kev thauj khoom txias rau hauv cov khoom noj khoom haus yog thawj kauj ruam hauv Asphalt Drum Mix Plant ua haujlwm. Cov cuab yeej siv feem ntau muaj peb lossis plaub lub thawv pub khoom noj (lossis ntau dua), thiab cov khoom sib xyaw tau muab tso rau hauv ntau lub thawv raws li qhov loj me. Qhov no yog ua kom qib sib txawv qhov ntau thiab tsawg raws li qhov project xav tau. Txhua qhov chaw muaj lub rooj vag txav tau los tswj cov khoom ntws. Hauv qab cov bins yog ib txoj hlua conveyor ntev uas thauj cov aggregates mus rau qhov screen scalping.

Cov txheej txheem tshuaj ntsuam yuav los tom ntej. Qhov no ib lub lawj vibrating npo tshem tawm cov aggregates loj thiab ua kom lawv nkag mus rau lub nruas.

Kev them nyiaj conveyor yog qhov tseem ceeb hauv cov txheej txheem asphalt cog vim tias nws tsis tsuas yog thauj cov khoom txias los ntawm qhov screen mus rau lub nruas tab sis kuj hnyav cov khoom sib xyaw. Qhov no conveyor muaj ib lub xov tooj ntawm tes uas tas li lom zem cov aggregates thiab muab lub teeb liab rau cov tswj vaj huam sib luag.

Lub tshuab ziab khaub ncaws thiab sib tov yog ua haujlwm ntawm ob txoj haujlwm: ziab thiab sib tov. Lub nruas no tig mus tas li, thiab cov khoom sib xyaw tau hloov ntawm ib kawg mus rau lwm qhov thaum lub kiv puag ncig. Cov cua sov los ntawm cov nplaim taws yog siv rau cov aggregates kom txo cov dej noo tsawg.

Lub tshuab ziab khaub ncaws ziab khaub ncaws cov roj tank khw muag khoom thiab xa cov roj rau lub nruas burner. Ib cag ntawm qhov ntawd, cov khoom tseem ceeb muaj xws li asphalt cia tso tsheb hlau luam uas khaws cia, cua sov, thiab twj tso kua mis xav tau asphalt rau lub nruas ziab kom sib tov nrog cov kub sib xyaw. Filler silos ntxiv yeem muab tub lim thiab cov ntaub ntawv khi rau lub tov khoom.

Kev tswj cov pa phem yog qhov tseem ceeb hauv cov txheej txheem. Lawv pab tshem tawm cov pa phem uas muaj feem cuam tshuam los ntawm ib puag ncig. Tus thawj plua plav collector yog cov khoom siv plua plav qhuav uas ua haujlwm nrog cov plua plav thib ob, uas tuaj yeem yog lub hnab lim lossis cov plua plav ntub dej.

Lub load-out conveyor sau npaj kub sib tov asphalt los ntawm hauv qab lub nruas thiab thauj mus rau lub tsheb tos lossis chaw cia khoom. Lub HMA tau muab tso rau hauv ib qho kev xaiv cia silo kom txog thaum lub tsheb tuaj txog.


Qhov sib txawv ntawm nruas asphalt nroj tsuag thiab counter flow asphalt nroj tsuag
1. Lub nruas yog qhov tseem ceeb hauv kev ua haujlwm Asphalt Drum Mix Plant. Nyob rau hauv ib tug parallel flow plant, cov aggregates migrate deb ntawm burner nplaim, whereas, nyob rau hauv ib tug counter flow plant, cov aggregates tsiv mus rau lub burner nplaim. Cov rhuab aggregates yog tov nrog bitumen thiab minerals nyob rau lwm kawg ntawm lub nruas.

2. Lub aggregate ntws nyob rau hauv ib tug parallel-flow nroj tsuag yog parallel mus rau lub burner nplaim taws. Qhov no kuj qhia tau hais tias cov aggregates txav deb ntawm cov nplaim taws thaum lawv mus. Cov ndlwg ntawm aggregates nyob rau hauv counter flow cog yog contrary (tawm tsam) rau cov burner nplaim, yog li cov aggregates tsiv mus rau lub burner nplaim ua ntej yuav tov nrog bitumen thiab lwm yam minerals. Qhov no zoo nkaus li ncaj nraim, tab sis nws ua rau muaj kev cuam tshuam loj hauv cov txheej txheem ntawm ob qho tib si ntawm asphalt mixers thiab txawm cuam tshuam rau HMA zoo. Nws raug suav hais tias qhov sib tov sib xyaw ua ke txuag cov roj av ntau dua thiab muab HMA ntau dua li lwm qhov.

Kev tswj vaj huam sib luag ntawm cov cuab yeej siv niaj hnub no yog niaj hnub thiab nyuaj. Lawv tso cai rau khaws cia ntawm ntau qhov sib xyaw ua ke raws li cov neeg siv khoom xav tau. Cov nroj tsuag tuaj yeem tswj tau los ntawm ib qho chaw los ntawm kev tswj vaj huam sib luag.
