Wetting Stage: Dej yog ntxiv rau ntub cov ntawv pov tseg, txo nws cov neeg kho tshuab lub zog thiab npaj rau kev ua haujlwm tom ntej.
Circulation Theem: Kev sib hloov thiab radial pulp ntws txhawb kev ntub dej thiab tsim kev sib txhuam.
Friction Stage: Qhov sib txawv ntawm qhov ceev uas tsim los ntawm lub rotor txoj kev sib hloov ua rau cov ntawv shredded los kua muag nyob rau hauv siab -shear force.
Lub hauv paus ntsiab lus thiab Kev Ua Haujlwm: Thaum lub sij hawm pulping, lub tank muaj dej thiab cov ntaub so ntswg, nrog lub ntsej muag rotating disc nyob hauv qab. Lub rotating disc generates ib tug loj vortex, subjecting lub pulp rau muaj zog tej yam kev mob thiab hydraulic shearing, thaum tib lub sij hawm raug rau txhua yam kev txiav txim ntawm cov hniav thiab kev sib txhuam ntawm cov ntaub so ntswg, ua rau fiber ntau disintegration thiab sib cais. Cov khoom siv pulped yog tawm los ntawm ib lub phaj sieve.
Cov yam ntxwv ntawm cov khoom: D- hom tank, rotor, sieve phaj, reducer, thiab lwm yam. Lub rotor muaj 8- hniav qauv, thiab lub sieve phaj muaj 16 hli aperture. Cov impurities hauv cov khoom siv raw nkag mus rau qhov chaw nres nkoj tso tawm los ntawm lub phaj sieve. Tag nrho cov txheej txheem yog nruab nrog lub tank hnyav slag, tuav lub thoob, hydraulic slag tshem tawm, hlua winnowing, thiab hlua cutter.
Tsawg-kev sib raug zoo hydraulic pulping: Cov txheej txheem pulping nrog kev ua haujlwm siab ntawm 3-5%, uas tuaj yeem ua tsis tu ncua lossis cuam tshuam. Muab cais raws li kev cuam tshuam pulping, nws siv cov kev cuam tshuam thiab shear quab yuam tsim los ntawm kev kub ceev rotor kom tawg cov fibers.
