Muchina wekugadzira asphalt unokwanisa sei kuderedza mari yaunoshandisa pakugadzirisa migwagwa yako?

Nei Vagadziri Vari Kubvisa Zvirimwa Zvisingachinji

Ngatiendererei mberi: nzira yechinyakare yekufambisa asphalt mixing plant haisisiri "yakanaka kuva nayo"; ndiyo nzira inokurumidza yekuderedza mabhiri ekutakura, hurongwa hwakaoma, uye vatengi vekanzuru vanofara. Kunyange zvakadaro, vazhinji vanoongorora vanoshamisika kana kusvetuka kubva pamapenzura asingachinji kuenda kumapenzura anotakurika kuchibuda zvechokwadi. Nyevero yeSpoiler: nhamba hadzinyepi, uye makomba anogadziriswa nehafu yenguva.

Mutengo Chaiwo weKutakura Hot Mix

Fungidzira izvi—uri kugadzira nzvimbo yekumaruwa iri kure nemakiromita makumi masere kubva pafekitori iri pedyo. Rori rega rega rine tembiricha ye160°C rinorasikirwa ne7°C paawa yekufambisa. Panguva iyo vashandi vepavege vanofamba, unenge watove uchitamba netembiricha yekuramba uye "kuburitswa-kuburitswa-kuburitswa" kunotyisa. Chishandiso chemota chinomira panzvimbo yacho chinobvisa njodzi iyoyo, uye, nekuverenga kwedu kwekupedzisira, tinochengetedza mari inosvika 14 USD patani mumari yekudziisa nekugadzirisa zvakare. Wedzera izvozvo ne15 000 t yebasa repakati nepakati rekugadzirisa uye watobhadhara mari yekurenda michina yekota inotevera.

Zvinhu Zvikuru Zvinosiyanisa Vanokunda Kubva Kune Vanoda Zvinhu Zvakasiyana

1. Kugadzirisa nekukurumidza, kusina zvishandiso

Tsvaga makumbo anopetwa nehydraulic uye madhiraivha anodzika ega. Kana mugadziri achiti "anoiswa mumaminitsi makumi matatu," kumbira vhidhiyo ye "time-lapse". Madhiraivha akanakisa ataongorora anosvika maminetsi makumi maviri nemasere, kusanganisira calibration. Chero chipi zvacho chinopfuura maminetsi makumi mana nemashanu chinodya hwindo rako rekugadzira zuva nezuva.

2. Kuchinjika kwemafuta

Magasi edhiziri ndiwo nhau dzanhasi. Mamodheru matsva anogamuchira mafuta anorema neLNG, zvichideredza kusvika 0.8 L patani yemusanganiswa. MuEurope, shanduko imwe chete iyoyo yakaderedza €70 000 kubva paprojekiti ye50 kt—zvakakwana kuti CFO yako inyemwerere sekunge mwaka wayo webhonasi.

3. Ring yekupwanya yeRAP iri mumutsara

Chigayo chidiki chenyundo chakavharirwa mukati me feed hopper chinokutendera kuti urasire asphalt pavement yakadzokororwa 100% pasina kugadziriswa. Net effect? ​​Unobhadhara mari ye quarry gate wozvirumbidza ne 40% virgin aggregate savings pa sustainability report. Zvakanaka, handiti?

Kuyera Chirimwa: Usabhadhara Kuwanda Kwezvaunoda

Mutemo mukuru: enzanisa simba remagetsi rinobuda paawa imwe neimwe nekumhanya kwemotokari. Chidzitiro che 10-ft (3 m) chichifamba ne 16 ft min⁻¹ (5 m min⁻¹) paukobvu hwe 2 in (50 mm) chinomedza anenge 110 th⁻¹. Sarudza dhiramu re 120 th⁻1 rinotakurika uye une 10% buffer ye micro-stops. Wedzera simba remagetsi uye unopisa mafuta akawanda uchideredza bheji re 160 th⁻1 rinopenya.

Mabhegi emidziyo inotakurika aimbove—ndingazvitaura sei—pfungwa yekuzotevera. Nhasi uno, fekitori yekusanganisa asphalt ine bhegi rearamid re550 gm⁻² uye feni inofambiswa neVFD inogona kusvika pa20 mg Nm⁻³ isina kupwanywa. Bhonasi: feni inoshanduka-shanduka inoderedza magetsi ne30% pakuchinjana kwemutoro. Izvozvo hazvisi zvekushambadza; takatora maawa maviri nemazana mana ekushanda muArizona uye takapfuura muganho weEPA ne40%.

Zvekufambisa: Zvausingazotaurirwi nemunhu

Mapemiti ndiwo anouraya chinyararire. Nyika dzakadai seCalifornia dzinoisa tireya ine 45-ft (13.7 m) se "yakanyanya" kana huremu hwe axle huchipfuura 20 000 lb (9 072 kg). Kurema kumwe chete kwakakanganiswa kunogona kuwedzera mutengo we convoy yako ne3 000 USD pamutsetse wega wega wenyika. Kumbira OEM kuti ikupe pepa re "dot-legal" usati wasaina PO. Ndivimbe, haudi kupokana ne patrol yemugwagwa na5am.

Calculator yeROI: Kubva kuSpreadsheet kuenda kuChokwadi

Takagadzira modhi yebhokisi rejecha redhipatimendi remigwagwa yedunhu raichinja 22 000 t pagore. Kuchinja kubva pakutenga hot mix (@ 95 USD t⁻¹ yakaunzwa) kuenda kukugadzirwa kwemafoni panzvimbo (@ 62 USD t⁻¹) kwakagadzirwa:

• Mari inochengetwa pagore: 726 000 USD
• Kubhadhara pa1.2 M USD plant: mwedzi 19.8
• Mari yasara mushure memakore mashanu: 45% yemutengo wekutenga

Kana muchina uyu ukashandisa 35% RAP, mutero wekabhoni we3% pagore unobhadharwa kaviri.

Ngano dzekuchengetedza—dzakabviswa

"Inotakurika yakafanana neyakapfava." Hazvichadaro. Mafuremu ehybrid anotengeswa zvakanyanya muChina/Europe anoshandisa simbi ye16 mm Q355D ine marobhoti welds. Shanduro: Hupenyu hwekugadzira hwemaawa makumi matatu kana kupfuura kunyangwe mushure mekutamiswa kwemakiromita chiuru chimwe. Ramba uchitevedzera purogiramu yemafuta eOEM uye unongoda kutsiva bhandi rekufambisa mhepo nguva dzese dze3.5 - zvakafanana neyuniti isingachinji.

Zvikanganiso Zvinowanikwa Pakutenga (uye Maitiro Ekudzivirira 'Em)

1. Kuregeredza kuenzana kwenzvimbo yacho. Drum rakagadzirwa nedombo re limestone rinopisa nepakati pemakoni kana ukaripa dombo remurwizi.
2. Kuderedza saizi yegenset. Wedzera 20% yemusoro wemota kuti utange kutonhora pakakwirira.
3. Kusashanda kwefekitori. Kushanya kwemazuva maviri kwetekinoroji (anenge makiromita mana) kunogona kudzivirira kukanganisa kwemakiromita makumi mana.

Kuchinja Vashandi Vako: Kukurumidza Kupfuura Zvaunofunga

MaHMI emazuva ano anowanzo shandiswa nema iPad ane dingindira re asphalt. Takadzidzisa vashandi vana muAlberta kwevhiki imwe chete; neMuvhuro vakanga vagadzira matani maviri nemazana matatu e19 mm Superpave asina mhepo inokuvadza. Murairo? Usarega "kudzidza" kuchikusunga wakasungirirwa kune chikara chekare chisingachinji.

Kuratidza Remangwana: Data uye Kuzvigadzira Otomatiki

Telematics ndiyo inotevera mujaho wezvombo. Chigadzirwa chekusanganisa asphalt chakabatana negore chinogona kukwidza tembiricha yekusanganiswa, matani paawa, uye mutengo wemafuta pafoni yemaneja wepurojekiti yako masekondi makumi matanhatu ega ega. Mamwe mainshuwarenzi anotobvisa 5% kubva pamari yemuchina kana ukagovana data iroro—mari yemahara kana ukadzvanya "hongu."

Mutsetse Wekupedzisira

Kana huwandu hwepavement yako yegore negore hunosvika matani 20 000 uye daro rekutakura zvinhu richipfuura makiromita makumi mana kunyange hafu yenguva, fekitori yekusanganisa asphalt inofambiswa haisi yekungonakidzwa chete—igwa rinokwikwidzana. Shandisa nhamba, chengetedza mari inochinjika, uye tarisa mitengo yako ichiderera ne8–12% uku mari yako ichikwira. Chinosuwisa chete ndechekuti varidzi vazhinji vanotaura kuti havana kukurumidza kuibvisa.
