Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov ntsia hlau xovxwm yog ua raws li kev siv cov ntsia hlau cais cov kua los ntawm cov khoom siv los ntawm kev siv lub zog. Cov ntsia hlau tig hauv ib lub cylindrical npo, thiab thaum nws tig, nws thawb cov khoom siv los ntawm qhov screen. Qhov no cais cov kua los ntawm cov khoom, tso cai rau cov kua tau sau thiab cov khoom tawm mus.
Ntawm no yog cov lus piav qhia ib kauj ruam ntawm kev ua haujlwm ntawm cov ntsia hlau xovxwm:
Cov khoom siv yog pub rau hauv xovxwm: Cov khoom yuav tsum tau muab tso rau hauv cov xovxwm los ntawm lub hopper los yog feed inlet.
Screw rotation: Cov ntsia hlau tig, ua rau cov khoom txav raws cov ntsia hlau hauv txoj kev helical.
Cov khoom raug thawb los ntawm lub vijtsam: Raws li cov ntsia hlau tig, nws thawb cov khoom siv los ntawm lub vijtsam, uas cais cov kua ntawm cov khoom.
Kev sib cais ua kua: Cov kua yog sau rau hauv ib lub trough lossis tank hauv qab ntawm lub vijtsam, thaum cov khoom siv raug thawb los ntawm lub vijtsam thiab tawm ntawm cov xovxwm.
Cov khoom pov tseg: Cov khoom siv yog tawm los ntawm cov xovxwm thiab muab khaws cia rau kev ua haujlwm ntxiv lossis pov tseg.
Kev sau ua kua: Cov kua uas tau sau los ntawm cov xovxwm tuaj yeem kho ntxiv lossis pov tseg, nyob ntawm daim ntawv thov tshwj xeeb.
Cov ntsia hlau xovxwm yog tsim los tuav ntau yam khoom siv, thiab feem ntau yog siv rau hauv ntau yam kev lag luam, xws li kev kho dej khib nyiab, kev ua zaub mov thiab dej haus, pulp thiab ntawv ntau lawm, kev ua liaj ua teb, mining, thiab roj thiab roj. Kev ua tau zoo thiab tus nqi-zoo ntawm cov ntsia hlau xovxwm ua rau nws yog qhov kev xaiv nrov rau ntau daim ntawv thov.
