Zeziphi Izinto Ezidibanisa Izityalo Ezivelisa I-Asphalt Eziqhuba Inzuzo Yexesha Elide?
Imephu yeNzuzo efihliweyo ngaphakathi kwisityalo sokuxuba iAsphalt
Uninzi lwabaqhubi lugweba isityalo ngokweetoni zaso ngeyure, kodwa imali yokwenyani ifihlwe nzulu— kwiindawo zesityalo sokuxuba i-asphalt ezigqiba ngokuthe cwaka ukuba utshisa ipetroli engakanani, zingaphi iilori ozilindayo, kwaye ukuba ujongene nokuvalwa okungalindelekanga kangaphi ngoMvulo kusasa. Wakuba uzibonile ezi ndawo zokusebenzisa amandla, ungacinezela umda owongezelelweyo kwii-aggregates ezifanayo ezibizwa ngokuba “yinkunkuma.”
Kutheni iCold Feed Bin ibeka ithoni yeDola nganye oyenzayo
Cinga ngebhini yokutya ebandayo njenge- metronome yesityalo; ukuba iyagungqa, yonke inyathelo elisezantsi liyagungqa ngayo. Iidrive zebhanti ezitshintshayo zanamhlanje ngoku zinciphisa ukutsalwa kwamandla ukuya kuthi ga kwi-15%, kodwa izityalo ezininzi zexesha lika-2005 zisasebenzisa iimoto zesantya esimiselweyo. Ukutshintsha ibhanti elawulwa yi-VFD kubiza kancinci kunebhini entsha, kwaye ii-SERPs zikaGoogle zibonisa uphendlo lwenyanga oluyi-1,900 lwe-"retrofit cold feed bin VFD" - ubungqina bokuba abaphathi bezityalo bafuna olu phuculo. Kulungile, ungalibali ukulinganisa isikali sebhanti rhoqo emva kweentsuku ezingama-90; ukugungqa kwe-2% kunokukubiza i-8,000 USD kwisamente ye-asphalt elahlekileyo ngexesha elinye lonyaka wokugawula.
IiDekhi zesikrini ezingcangcazelayo: Isihluzo esisindisa okanye esiba i-RAP yakho
Iingxubevange ze-High-RAP zinenzuzo kuphela xa iidekhi zakho zesikrini zigcina amaqhezu ethembekile. Ukuvulwa okugugileyo kwe-4.75 mm kunokuvumela iitships ezirhabaxa zingene kwibhini encinci, nto leyo ekwenza ufune ukongeza i-virgin filler ukuze ufikelele kwi-spec—ngokusisiseko uguqula ukonga okusetyenzisiweyo kube yindleko entsha. Ukutshintshela kwiiphaneli ze-polyurethane ezithintela ukufiphala kwandisa ubomi benkonzo ukusuka kwiinyanga ezi-9 ukuya kwezi-18 kwaye kunciphisa ixesha lokungasebenzi nge-30%. “Sizinqumle ii-invoyisi zethu zelaphu lesikrini phakathi,” utshilo umvelisi waseMissouri kwinyanga ephelileyo, “kwaye uluhlu lwezinto zezityalo zokuxuba i-asphalt ekugqibeleni luyancipha endaweni yokukhula.”
Idrama Yokomisa: Apho Iindleko Zepetroli Zibhalwa Ngentsimbi
Uyilo lokubhabha lelona qhawe lingaqhelekanga apha. Idrama ye-9-cubic-meter eneenqwelo-moya eziqhelekileyo isebenzisa malunga ne-8.5 L yedizili ngetoni nganye yomxube, ngelixa i-flight array yakutshanje engabonakaliyo, egcina ixesha elide inciphisa loo nto iye kwi-6.9 L. Kwi-3.50 USD ngegaloni nganye, loo delta ilingana ne-12,000 USD ngenyanga kwisityalo se-200-tph. Ukuba usasebenzisa idrama ka-2006, ukuphuculwa kokubhabha—hayi ukutshintshwa kwedrama epheleleyo—kunokuzihlawulela kwiinyanga ezili-14. Oh, kwaye soloko ujonga ukulungelelaniswa kwe-trunnion; ukungalingani kwe-3 mm kunokunyusa amaqondo obushushu e-trunnion ngezihlangu ngama-20 °C kwaye kuthumele iqela lakho lokulungisa lixakekile.
Igumbi Lokutshisa Nokutsha: Irejista Yemali Eyi-1,300 °C
Ulawulo lwe-oksijini lwaluyinto yodidi oluphezulu; ngoku sele benelungelo lokuprinta imali. Ukunciphisa i-oksijini engaphezulu kwe-1% kuthetha ukonga i-1.1% yamafutha. Kwisityalo se-150-tph esisebenza iiyure ezingama-2,000 ngonyaka, oko kuthetha i-11,000 L yamafutha, okanye malunga ne-9,000 USD. Iibhanti zezixhobo zesityalo sokuxuba i-asphalt ezintsha zidibanisa i-burner nefeni yomoya ovuthayo oguquguqukayo, okukuvumela ukuba ucofe i-RPM yefeni ngetoni ephantsi endaweni yokopha emoyeni obandayo nge-damper. Isiphumo? Ugcina imo yelangatye iqinile kwaye umhloli we-NOx wonwabile.
I-Hot Elevator kunye ne-Screening Deck: I-Bottleneck Ongasoze Uyiqaphele
Xa ibhanti yelifti ityibilika, yonke imboni iyabuyela umva njengemoto etollbooth. Ipulley yentloko elahliweyo nge-ceramic kunye ne-automatic belt tensioner ziinshurensi engabizi kakhulu. Omnye umqhubi eTexas ufunga ngenkqubo yemihla ngemihla yemizuzu eli-10 "walk-the-belt"; ubamba imiphetho eqhekekileyo ngaphambi kokuba itshibilike ngoLwesihlanu emva kwemini. Icebiso lobuchule: gcina ibhanti elongezelelweyo kwitreyila yezixhobo—ukuhanjiswa ngebhanti yelifti yeenyawo ezili-180 ngokwezifiso kungathatha iintsuku ezili-14, kwaye ezo ziintsuku ezili-14 zezivumelwano zokutyibilika ezilahlekileyo.
Umxube wePugmill: Apho Umgangatho woMxube Uba Ligama
Amaxesha amafutshane okuxuba agcina iindawo ezigugileyo kodwa anokushiya umsi oluhlaza okwesibhakabhaka ujinga phezu kwesityalo. Kwelinye icala, ukuxuba kakhulu kutshisa ukujika kwaye kunyuse ubushushu budlule kwi-170 °C, okubangela ukuqhekeka kwe-polymer kwiibhanti eziguquliweyo. Indawo entle kwiingxube ze-SMA ezininzi yimizuzwana engama-28-32. Phucula uye kwiingcebiso ze-paddle ezine-chrome kwaye uzitshintshe rhoqo emva kweetoni ezingama-60,000; ixabiso lincinci xa lithelekiswa nomsebenzi wokukrazula kuba umxube wakho awuphumelelanga kwiinkcukacha zamandla okutsalwa. Kwaye, gcina ii-paddles ezimbalwa ezindala njenge "iironi zokuvavanya" xa uzama ipesenti entsha ye-RAP—ziya kukuxelela ngokukhawuleza ukuba ulayisha kakhulu i-pugmill.
Indlu yeengxowa okanye iWet Scrubber: Isikhuselo sokuthobela imithetho esinokubamba ubushushu
Ucango lwebhegi oluvalwe kakubi lukhupha ubushushu kwaye lwehlisa ubushushu obungaphantsi kombethe, luguqula uthuli olungeyongozi lube ludaka olune-asidi olutya iingxowa zesidlo sakusasa. Ukutshintshela kwiingxowa ezine-PTFE ezinesiseko sefelt esingu-16-oz kunokunciphisa umahluko woxinzelelo nge-300 Pa, konge i-7 kW kwi-fan motor. Ngaphezulu konyaka oko kungama-5,000 kWh, okanye malunga ne-650 USD. Ayisiyonto imbi, kodwa yimali ongasenakuyizuza ngokufumana iitoni ezongezelelweyo.
Inkqubo Yolawulo: Ingqondo Eguqula Intsimbi Ibe Yiqhinga
Iiphaneli ezindala zebhetshi zinyanzela abaqhubi ukuba babhale phantsi iindlela zokupheka ezixutyiweyo kwiincwadana ezinamafutha. Iibhanile zanamhlanje ze-PLC+HMI zigcina amakhulu eendlela zokupheka kwaye zilungise ngokuzenzekelayo iigeyithi ze-feeder ngokusekelwe kwiiprobes zomswakama. Ibali le-ROI? Ukunciphisa nge-3% ekusetyenzisweni kwesamente ye-asphalt engavuthwanga kwisityalo se-150-tph konga i-45 t ye-binder ngenyanga—yibize nge-22,500 USD ngamaxabiso anamhlanje. Iideshibhodi zelifu zikwavumela umphathi we-QC ukuba abone ubushushu buhamba kwishifti yoMvulo ebusuku aze athumele umyalezo kumphathi ngaphambi kokuba ilori yokuqala iphume ngoLwesibini kusasa. Olu luhlobo lokudibanisa izinto zesityalo sokuxuba i-asphalt olugcina abahloli be-DOT bencumile.
I-Load-Out Silo: Indawo Yokugqibela Oyilindeleyo Yokulahlekelwa Yi-50,000 USD
Isili nganye emile okwekhowuni ekugqibeleni ifumana iqela elingaphandle kwesiseko elidilikayo lize liwise ikhowuni. Isili ye-200-ton ibiza i-40,000 USD ukuyitshintsha, kunye nenye i-10,000 USD kwimveliso elahlekileyo. Ukufaka i-360° carbon-fiber wrap ngaphakathi kwikhowuni kongeza i-8,000 USD kwixabiso lokuthenga kodwa kwandisa ubomi benkonzo ye-high-RAP. Omnye umvelisi wase-Illinois wagqiba isili nganye ngo-2019 kwaye akakayitshisi i-crack ukususela ngoko.
Izinto ezibalulekileyo ekufuneka ziqwalaselwe zii-CFO kunye neeForemen ngokufanayo
- Uhlaziyo olujolise ekuphuculeni ngembuyekezo emfutshane kuqala—ii-VFD kwiibhanti zokufunxa ezibandayo, i-oxygen trim, kunye neephaneli zesikrini ezithintela ukufiphala.
- Landelela ubomi bezinto ezisetyenzisiweyo kwiiyure, kungekhona iinyanga zekhalenda; ukubhabha kwedrama okuhlala iiyure ezingama-9,000 kumxube we-RAP ephantsi kunokungaphumeleli kwiiyure ezingama-6,000 nge-40% ye-RAP.
- Sebenzisa iGoogle Trends ukujonga ukunyuka kwexesha lonyaka "kwiindawo zokulungisa izityalo ze-asphalt" kunye noku-odola kwangaphambili izinto ezingasetyenziswayo ngaphambi kokuba imfuno inyuse amaxabiso.
- Faka ikhowudi yeQR kwinxalenye nganye ebalulekileyo edibanisa nevidiyo yolondolozo yemizuzwana engama-90; nomntu omtsha akanakuyixuba indlela yokuthambisa.
Ingongoma ephambili? Xa uphatha nganye yezi zinto ziyinxalenye yesityalo sokuxuba i-asphalt njengento enika inzuzo endaweni yokuba ibe yindleko, isityalo asisayi kuba yibhokisi emnyama size sibe yispredishithi onokusilawula. Kwaye loo nto, mhlobo wam, yindlela oguqula ngayo umxube oshushu ube yimali ebandayo—ngaphandle kwegrama, ewe.
