Uhlobo lokugeleza phansi lusho ukuthi ukugeleza kokugeleza komoya oshisayo kuyafana naleyo yezinto ezibonakalayo, zombili zisuka ekugcineni kokuphakelayo ziye ekugcineni kokukhipha. Lapho impahla ingena nje emgqomeni, amandla okushayela okomisa makhulu futhi okuqukethwe kwamanzi mahhala kuphezulu. Ijubane lokumisa lengxenye engaphambili yohlobo lokugeleza lishesha kakhulu, bese kuthi njengoba impahla iqhubekela embotsheni yokukhipha, izinga lokushisa lempahla liyakhula, amandla okushayela okomisa abe mancane, umswakama wamahhala uyancipha, kanye nesivinini sokumisa. futhi yehlisa ijubane. Ngakho-ke, ukomiswa kwesigubhu esomisa ukugeleza phansi akulingani kunohlobo lokugeleza okuphikisayo.

Uhlobo lokugeleza okuphikisayo ukuthi isiqondiso sokugeleza kokugeleza komoya oshisayo kuphambene nesiqondiso sokunyakaza kwento, futhi izinga lokushisa lesigubhu liphakeme kakhulu ekugcineni kokuphuma kwempahla, futhi izinga lokushisa liphansi ekugcineni kwento yokungena. . Izinga lokushisa lempahla liphansi kakhulu lapho lingena kuqala esigubhu, futhi izinga lokushisa liphezulu kakhulu ekugcineni kwe-outlet, elisendaweni efanayo nezinga lokushisa eliphezulu neliphansi lesigubhu. Ngoba izinga lokushisa eliphakeme kakhulu lesigubhu lisohlangothini olufanayo nezinga lokushisa eliphakeme kakhulu lezinto ezibonakalayo, futhi izinga lokushisa eliphansi kakhulu lesigubhu lisohlangothini olufanayo nezinga lokushisa eliphansi kakhulu lempahla, ngakho-ke amandla okuqhuba ukomisa okuphikisanayo kufana kakhulu. kunalokho okomisa phansi komfula.

Ngokuvamile, ukushisa kwesigubhu kwenziwa ngokuyinhloko nge-convection yokushisa. Uhlobo lokugeleza phansi lusho ukuthi igumbi elivuthayo kanye ne-inlet yokuphakelayo kufakwe ohlangothini olulodwa, futhi isiqondiso sokugeleza kokugeleza komoya oshisayo kuyafana naleyo nto. Uma kungenjalo, kuwuhlobo lokugeleza okuphikisayo.

Lapho isigubhu esiphikisayo sisomisa futhi sifudumala, ingaphakathi lesigubhu esomile lingahlukaniswa libe yizindawo ezintathu ngokuya ngokushintsha kwezinga lokushisa lezinto ezibonakalayo: indawo yokunciphisa umswakama, indawo yokomisa nendawo yokushisa. Ngoba impahla iqukethe umswakama lapho ingena okokuqala esigubhu, umswakama obalulekile uzosuswa endaweni yokuqala, isamba sizomiswa endaweni yesibili, futhi isigubhu sizoba ezingeni lokushisa eliphakeme kakhulu endaweni yesithathu Xhumana no izinto ezomisiwe ukukhulisa izinga lokushisa. Ngokuvamile, njengoba izinga lokushisa lempahla likhuphuka esigubhini esiphikisanayo, indawo yokomisa nayo iyanda, ngakho amandla okomisa ayafana, umehluko ophakathi kwezinga lokushisa phakathi kokugeleza komoya oshisayo nezinto ezibonakalayo mkhulu, kanye nokusebenza kahle i-counter-current drying ilula kakhulu. ukugeleza phezulu.

Useisitshalo sokuxuba i-asphalt sohlobo lwesigubhu, isigubhu sinemisebenzi emibili, ukomisa nokuxuba; ngenkathi ukuisitshalo se-asphalt sokuxuba i-batchkanye neisitshalo esiqhubekayo sokuxuba i-asphalt, isigubhu sidlala indima yokushisa kuphela. Ngenxa yokuthi ukuxuba ku-batch kanye nezitshalo eziqhubekayo zokuxuba i-asphalt kwenziwa ngebhodwe lokuxuba, asikho isidingo sokwengeza i-asphalt esigubhini sokuxuba, ngakho-ke kusetshenziswa isigubhu sokumisa esiphikisayo esinokomisa okuphezulu.
