Izidingo zokushisa nezomisa zamaminerali amanzi anomswakama ophezulu ohlelweni zisebenzisa amandla amaningi kagesi, okwenza isidingo sokukhethwa kwamafutha esistimu yokuvulwa okuhlobene eduze nesimo esithile. Kumafutha avamile afana negesi yemvelo, amalahle nezinye izibaso ezifana ne-methanol, okokusebenza kwebitumen melter kunokusebenza okwanele kokucubungula futhi ivelu yekhalori ayikwazi ukusetshenziswa ngokugcwele. Ngakho-ke, uhlelo lwezitshalo zokuncibilikisa itiyela kufanele lukhethe amafutha afana nezinjini zikadizili namafutha asindayo.
I-bitumen melter equipments uwoyela osindayo, owaziwa nangokuthi uwoyela wamafutha amancane, uwuketshezi olunsundu ngokumnyama olufakwe ekuthuthukisweni okusimeme ngokwe-Hague Convention. Ngamanye amazwi, uwoyela osindayo unezici ze-viscosity ephezulu, umswakama ophansi, i-sediment encane, kanye nokuguquguquka okunzima kwezinto zokusebenza ze-bitumen melter. Imishini yokuncibilikisa itiyela uwoyela osindayo ubiza kakhulu kunezinjini zikadizili, ngakho ufaneleka kakhulu njengophethiloli wengxube yetiyela kanye nemishini yokukhiqiza yezitshalo zebitumen melter.

Ukuthuthukiswa nokuguqulwa kwezinto ezincibilikisa itiyela kungase futhi kuzuze umphumela olindelekile wokonga amandla kanye nokunciphisa ukungcola. Ngakho-ke, kuyadingeka ukuthuthukisa imishini yokuncibilikisa itiyela enezinjongo ezimbili ezisindayo bese ushintsha iphampu kawoyela esindayo ngowoyela omncane kanye ne-valve yokuguqula uwoyela esindayo engakwazi ukuthwala ukucindezela okuphezulu komkhiqizi wezitshalo zokuxuba i-asphalt. Kuyadingeka futhi ukuthi kuthuthukiswe uhlelo lokuhlinzeka ngowoyela osindayo kanye nohlelo lokucubungula isitshalo sebhitumu yemvelo elicindezelwe, futhi kuthuthukiswe uhlelo lokulawula izimoto. Nakuba ukuthuthukiswa kwemboni yokuncibilika kwebitumen kuzodala umthwalo othile wezomnotho okwesikhashana, kusukela enkambisweni yentuthuko yesikhathi eside, ngokombono wokongiwa kwamandla kanye nokunciphisa ukungcola, izindleko zingabuyiswa ngesikhathi esifushane, ngaleyo ndlela kukhiqize izinzuzo ezinkulu zezomnotho.
Indlela yokuthuthuka yethiyori yokomisa yesitshalo sokuncibilika kwebitumen idinga ukucutshungulwa, ukomiswa kanye nokushisisa kwemithombo yamatshe. Isizathu siwukuthi ikhwalithi yezinto zokusetshenziswa ezimanzi ayikwazi ukuhlangabezana nezidingo zokukhiqiza izitshalo ze-bitumen ezincibilika kanye nezinkampani zobuchwepheshe bokucubungula. Isitshalo esincibilikisa itiyela nezinto zokusetshenziswa kuya ngokuya ngokuya phezulu, uhlelo lokusebenza lwesistimu yolwazi yokomisa lunamandla amakhulu okuqina, ikakhulukazi izingxube zetiyela ezimunca uma kuqhathaniswa. Ucwaningo luye lwabonisa ukuthi lapho umswakama ohlobene wemishini yokuncibilikisa itiyela yamatshe udlula u-1%, inkinga yokusetshenziswa kwamandla ingase iqhubeke ikhula ngo-10%. Akunzima ukubona ukubaluleka kokulawula umswakama wetshe.
Phakathi nenqubo yokukhiqiza, okokusebenza kwe-asphalt de-barreling kufanele kuthathe izinyathelo ezifanele zokulawula umswakama wemabula. Isibonelo, ukuze kuzuze kangcono ipayipi lendle, indawo evamile yokubeka imabula kufanele ibe nomthambeka othile, futhi ukhonkolo kufanele usetshenziswe phansi ukuze uqine. Kufanele kube namanzi aguquguqukayo abanzi eduze nendawo. I-asphalt de-barreling equipment awning kufanele yakhiwe endaweni ye-asphalt de-barreling equipment ukuvimbela imvula ukuthi ingangeni. Ngaphandle kwetshe elinomswakama ophezulu ohlobene, izinhlayiya zamatshe zokucaciswa namazinga nazo ziyadingeka ohlelweni lokumisa. Ngesikhathi sokusebenza kwemishini ye-asphalt de-barreling, ukusatshalaliswa kosayizi wezinhlayiyana zamatshe kungaphansi kwe-70% yezinga elifanelekile, elizokwandisa ukuchichima, futhi nakanjani kuzoholela ekusetshenzisweni kukaphethiloli. Ngakho-ke, kuyadingeka ukulawula ngokuqinile usayizi wokusabalalisa usayizi wezinhlayiyana zamatshe, futhi uhlele amatshe ngokusatshalaliswa kosayizi wezinhlayiyana ezihlukene ukuze kwandiswe amandla okuqina okusebenza kwemishini ye-asphalt de-barreling.
