Mfundo yogwiritsira ntchito pampu ya slurry imayamba ndi choyikapo chozungulira. Slurry amalowa m'malo olowera, amalandira liwiro kuchokera ku chopondera ndikulowa m'bokosi. Chophimbacho chimasintha slurry iyi kukhala yotuluka. Chifukwa chakuti sing'anga imanyamula zolimba, njira yothamanga ndi yayikulu kuposa ya pampu yamadzi yokhazikika, ndipo mapeto amadzi ayenera kusankhidwa kuti avale.
Mafomu osiyanasiyana oyika amagwiritsa ntchito mfundo yofanana. Pampu yopingasa nthawi zambiri imayendetsedwa ndi mota kudzera pa kulumikizana kapena lamba. Pampu yoyima kapena yozama imatha kugwira ntchito pafupi ndi dzenje kapena pansi pamadzi. Chophimba, liner, mbale ya alonda ndi zigawo zosindikizira zimakonzedwa mosiyana, koma slurry amapezabe mphamvu kuchokera ku choyimitsa.
Kuchita kwenikweni kumadalira mutu, kuyenda, kuthamanga, kuchuluka kwa slurry ndi kukula kwa tinthu. Ngati chitsanzocho ndi chaching'ono kwambiri, zolimba zimatha kukhazikika kapena pampu imatha kuvala mofulumira. Ngati pampu ithamanga kwambiri, abrasion imatha kuwonjezeka. Deta ya pampu yamatope imatchulanso chilolezo chosinthika pakati pa chopondera ndi liner, chomwe chimathandizira kusunga zotuluka pambuyo povala.
Mfundoyi ndi yosavuta kufotokozera, koma momwe malowa alili ayenera kuyang'aniridwa mosamala. Phulusa labwino, ore coarse ndi sludge wandiweyani sizimachita chimodzimodzi. Liwiro la mpope, zida za liner, mawonekedwe osindikizira ndi njira yotulutsira zimayenera kufanana ndi slurry yeniyeni pompayo isanayambe kugwiritsidwa ntchito.
