Zomera Zosakaniza ndi Batch: Kulondola Komwe Kumadzipindulitsa Kokha Pantchito Yapadera

Ngati boma lanu la DOT likuvomerezabe mbendera ya "100% Marshall", chomera cha batch ndi tikiti yanu yagolide. Batch iliyonse imayesedwa mpaka paundi, kutenthedwa mpaka pamlingo woyenera, ndikusakanizidwa mu pugmill yomwe imawoneka ngati galimoto yaying'ono ya simenti pa steroids. Zabwino zake? Mutha kusintha kuchuluka kwa laimu, kuchuluka kwa ulusi, kapena ma polymer nibs popanda kuipitsa katundu wotsatira. Vuto lake ndi chiyani? Muyenera kuyimitsa njirayi masekondi 40-60 aliwonse kuti itulutse, kotero ma tonnage ola limodzi amafikira pafupifupi 240 t/h pa ma pugmill ambiri a matani 4.

Chenjezo lobisika la mtengo: Kuyimitsa kaŵirikaŵiri kwa spike burner cycling; mudzadya mafuta ochulukirapo ndi pafupifupi 15% pa tani poyerekeza ndi ng'oma. Komabe, pamene zilango za kusakaniza kosagwirizana ndi spec zikufika pa $2,000 pa tani, masamuwo ndi owopsa koma osavuta: gulu limalipira lokha mu mayeso amodzi a QC omwe simunachitepo.

Zomera Zosakaniza Drum: Wothamanga Marathon wa Ntchito Zokhala ndi Volume Yambiri, Zosasintha Kwambiri

Sinthani rhythm ya stop-start ndi riboni yopitilira ya aggregate ndipo mupeza ng'oma yofanana yofanana . Chifukwa malo owuma ndi osakaniza amagawana chipolopolo chozungulira chomwecho, mutha kukankhira 350–450 t/h popanda kutuluka thukuta. Kodi vuto ndi chiyani?

Momwe Mungasankhire Pakati pa Mitundu ya Zomera Zosakaniza Asphalt Popanda Kudandaula Nazo M'nyengo Yozizira Ikubwerayi

Yambani ndi zinthu zitatu zomwe sizingakambirane zomwe ulusi wa Reddit umadumphadumpha:

1. Malire a mpweya woipa m'deralo —Ngati AQMD yanu ichepetsa PM pa 0.04 gr/dscf, zomera zokha zotsutsana ndi mpweya kapena zosakanikirana ndizomwe zingafikire chiwerengerochi popanda malo osungiramo katundu omwe amawononga ndalama zokwana 300 k.
2. Kukula kwapakati pa ntchito —Pansi pa matani 40,000 pachaka, ndalama zokhazikika za chomera cha batch zimaposa zabwino zake za QC; pitirizani kugwiritsa ntchito drum kapena counter-flow.
3. Kupezeka kwa RAP —Maboma tsopano alamula kuti 25% ibwezeretsedwenso pamitengo yambiri. Ngati simungathe kuipatsa, mumachotsedwa ntchito musananole pensulo yanu.

Kenako, yendetsani chitsanzo cha NPV cha zaka 10 pogwiritsa ntchito zolosera zenizeni za mafuta, magetsi, ndi msonkho wa kaboni (mtengo wa ETS wa EU wangofika pa 90 €/t). Mudzapeza kuti kukhala ndi chomera chotsutsana ndi kayendedwe ka madzi mu 2025 kuli ngati kukhala ndi Bitcoin mu 2019—koyambirira, koma osati kwa nthawi yayitali.

Ndalama Zoyendera: Chosintha Chobisika Chomwe Chimasandutsa Opambana Kukhala Otayika

Tiyerekeze kuti mwabwereka galimoto yoyendera mphamvu ya 350-t/h yomwe ili pamtunda wa makilomita 90 kuchokera kuntchito. Mtengo wanu wokwera ndi $0.18 pa tani imodzi ndipo mumataya kutentha kwa 5% pa ola limodzi paulendo. Chitani masamu: 180 miles ulendo wobwerera × $0.18 × 1.05 chilango cha kutaya kutentha = $34 pa tani musanayike mzere umodzi wozungulira. Mwadzidzidzi fakitale yotsika mtengo si yotsika mtengo. Mfundo yanga? Ganizirani za radius yanu yapakati yonyamula katundu musanakonde ma tonnage specs onyezimira pa kabuku.
