Ng’oma imayikidwanso pamalo otsetsereka pang’ono. Komabe, choyatsiracho chimayikidwa kumapeto kwapamwamba komwe kuphatikizira kumalowera m'ng'oma. Njira yowonongeka ndi kutentha, komanso kuwonjezera ndi kusakaniza kwa asphalt yotentha ndi ufa wa mchere (nthawi zina ndi zowonjezera kapena ulusi), zonse zimatsirizidwa mu drum. Kusakaniza kwa asphalt komalizidwa kumasamutsidwa kuchoka ku ng'oma kupita ku tanki yosungiramo katundu kapena galimoto yonyamula katundu.
Ng'oma ndi gawo lomwe limagwiritsidwa ntchito mumitundu yonse ya zomera zosakaniza phula, koma njira yogwiritsira ntchito ndi yosiyana. Ng'omayi imakhala ndi mbale yonyamulira, yomwe imakweza ng'omayo pamene ng'oma ikutembenuka ndikupangitsa kuti igwere kupyolera mu mpweya wotentha. Muzomera zapakati, mbale yokweza ng'oma ndi yosavuta komanso yomveka; koma kupanga ndi kugwiritsa ntchito zomera zopitirira zimakhala zovuta kwambiri. Zachidziwikire, palinso malo oyatsira mu ng'oma, cholinga chake ndikuletsa lawi lamoto kuti lisakhudze gulu lonselo.
Njira yothandiza kwambiri yowumitsa ndi kutenthetsa ponseponse ndi kutentha kwachindunji, komwe kumafuna kugwiritsa ntchito choyatsira kuti chiwongolere lawi lamoto mu ng'oma. Ngakhale zigawo zikuluzikulu za choyatsira mu mitundu iwiri ya zomera zosakaniza phula ndi zofanana, kukula ndi mawonekedwe a lawi lamoto kungakhale kosiyana.
Ngakhale pali njira zambiri zopangira mafani opangira mafani, mitundu iwiri yokha ya mafani opangira ma centrifugal omwe amagwiritsidwa ntchito kwambiri pazosakaniza za asphalt: mafani a radial impeller centrifugal ndi mafani akumbuyo a centrifugal. Kusankhidwa kwa mtundu wa impeller kumatengera kapangidwe ka zida zosonkhanitsira fumbi zomwe zimagwirizana nazo.
Dongosolo la chitoliro lomwe lili pakati pa ng'oma, fani yochititsa chidwi, chotolera fumbi ndi zinthu zina zofananira zidzakhudzanso magwiridwe antchito a chomera chosakaniza phula. Kutalika ndi mawonekedwe a ma ducts ayenera kukonzedwa mosamala, ndipo kuchuluka kwa ma ducts mu machitidwe ocheperako kumakhala kopitilira muyeso wopitilira, makamaka pakakhala fumbi loyandama mnyumba yayikulu ndipo liyenera kuyendetsedwa bwino.
