Ngokwenkqubo yokuvelisa, izityalo zebhitumene eziguquliweyo zinokwahlulwa zibe ziindidi ezintathu: ukusebenza kwesixhobo sebhitumene esiguquguqukayo esiguquguqukayo, ukusebenza kwesixhobo sebhitumene esiguquguqukayo esiqhubekayo, kunye nokusebenza ngokuqhubekayo kwesixhobo sebhitumene esilungisiweyo. Ngexesha lokwenziwa kwezixhobo ezilungisiweyo zebhitumene emulsified, idemulsifier, iasidi, amanzi, kunye nelatex imathiriyeli elungisiweyo ixutywa kwitanki yokuxuba isepha, emva koko impompelwe kwilitye lokusila ngebhitumene. Emva kokuba itanki yesepha isetyenzisiwe, izaliswa ngesepha, kwaye emva koko ukuveliswa kwetanki elandelayo kugqityiwe.

Isityalo sebhitumene elungisiweyo emulsified esikhankanywe apha siquka impompo yamanzi ashushu kunye nempompo ejikelezayo. Olu hlobo lwempompo yamanzi eyi-centrifugal ngokuqhelekileyo lusebenzisa umbhobho wempompo ye-centrifugal. Kukho indawo yogutyulo lwelindle emazantsi kumbhobho wempompo ye-centrifugal. Qaphela ukuba yindawo yokukhupha amanzi amdaka esezantsi kwempompo yesixhobo sebhitumene ehlaziyiweyo emulsified. Amanzi akwitanki yamanzi akhutshwa ngevalve yokucoca. Ezinye izixhobo zebhitumene ezilungisiweyo azinaso isihluzo sokugcina iindleko zesixhobo, ngoko ke sinokukhutshwa kuphela ngokukhulula iibholithi ze-ankile zeflange ezantsi. Zimbini iintlobo zezityalo zebhitumene ezixutyiweyo kwimarike, iimpompo zegiya okanye iimpompo ze-centrifugal. Iimpompo zegiya zinokukhupha kuphela ulwelo kwimpompo ngeflange yokudibanisa yombhobho. Iimpompo ze-Centrifugal zicoca ilindle ngeendawo zazo zogutyulo.
Xa isetyenziselwa ukuveliswa kwesixhobo sebhitumene e-emulsified, ngokwetekhnoloji yohlengahlengiso olwahlukeneyo, umbhobho we-latex unokudityaniswa phambi komatshini wokusila we-colloid okanye emva komatshini wokusila we-colloid, okanye akukho mbhobho we-latex, kodwa isixa esifunekayo se-latex songezwa ngesandla itanki yesepha.
Isixhobo sebhitumene esakhiweyo siqhele ukusebenzisa umphantsi wekhowuni. Nangona kunjalo, ukuze kuqhutywe ngcono i-coefficient ye-bitumen emulsified, i-inlet kunye ne-outlet ayidlanga ukuba ibekwe ezantsi. I-emulsion yokuthambisa (uninzi lwamanzi) iya kuhlala iphantsi kwetanki, kwaye le nxalenye yolwelo oluseleyo kufuneka ikhutshwe ngevalve yokucoca ezantsi. Zombini izinto ezishushu nezibandayo kwindawo yokutshintsha ubushushu besixhobo sebhitumene emulsified kufuneka zikhutshwe.
Kuya kubakho i-emulsion eseleyo okanye amanzi kwi-colloid mill. Umsantsa phakathi kwe-stator kunye ne-rotor ye-colloid mill ingaphakathi kwe-1mm. Ukuba kukho amanzi amancinane ashiyekileyo kwizixhobo zebhitumene eziguquliweyo, oko kuya kubangela ingozi yezityalo zebhitumene eziguquliweyo. Intsalela kwi-colloid mill inokunyangwa ngokukhulula iibholithi zoqhagamshelo lwemibhobho yemveliso egqityiweyo. Umzimba wevalvu wezixhobo ezininzi zebhitumene eziguquliweyo zithatha uhlobo lwe-pneumatic, kwaye kuya kubakho icandelo lempompo. Umthamo wamanzi emoyeni uya kuba ngamanzi agcinwe kwitanki emva kokwandiswa. Le nxalenye yamanzi kufuneka ikhutshwe ebusika.
Xa ukhupha amanzi okanye umbhobho we-emulsion wokunyakamisa weplanti yebhitumene elungisiweyo e-emulsified, ivalve yebhola kufuneka ibe kwindawo evulekileyo. Ukuba kukho amanzi kwisixhobo sebhitumene ehlaziyiweyo emulsified ngexesha lokusebenza okanye impompo yokufunxa ibangelwa kukuvalwa kwevalve, ulwelo olukwimpompo kunye nombhobho alukhutshelwa, nto leyo eya kubangela ingozi yengozi yesixhobo sebhitumene eguquliweyo. Ukupholisa kwamanzi ajikelezayo kwi-colloid mill, ezininzi ii-colloid mill zisebenzisa izitywina zomatshini, eziza kusebenzisa ukupholisa kwamanzi ajikelezayo. Le ndawo yokupholisa amanzi ajikelezayo kufuneka ikhutshwe. Ezinye iindawo apho amanzi anokubakho. Umbhobho we-oyile ogqithisela ubushushu obuphezulu kwiplanti yebhitumene eguquliweyo akulula ukujiya ebusika kwaye akufuneki ukuba ukhutshwe. Izityalo ze-bitumen ezilungisiweyo ze-emulsified ziya kuxutywa ebusika, kodwa umthamo akulula ukunyuka ngexesha lenkqubo yokudibanisa kwaye ayifuni ukuchithwa.
