Makina owunikira mchenga wowuma amatha kugawidwa m'mitundu itatu: mtundu wamtundu wa vibration, mtundu wa cylindrical ndi mtundu wa swing.Popanda zofunikira zapadera, tili ndi makina owonera amtundu wa vibration pamzerewu.Bokosi lowonekera la makina owonetsera liri ndi dongosolo losindikizidwa bwino, lomwe limachepetsa bwino fumbi lomwe limapangidwa panthawi yogwira ntchito.Sieve box side plates, mbale zotumizira mphamvu ndi zigawo zina ndizitsulo zapamwamba za aloyi, zokhala ndi zokolola zambiri komanso moyo wautali wautumiki.Mphamvu yosangalatsa yamakinawa imaperekedwa ndi mtundu watsopano wamagalimoto apadera ogwedezeka.Mphamvu yosangalatsa imatha kusinthidwa mwakusintha chipika cha eccentric.Chiwerengero cha zigawo za chinsalu chikhoza kukhazikitsidwa ku 1-3, ndipo mpira wotambasula umayikidwa pakati pa zowonetsera zamtundu uliwonse kuti chinsalucho chisatseke ndikuwongolera kuwonetsetsa bwino.Makina owonera amtundu wa vibratory ali ndi zabwino zamapangidwe osavuta, kupulumutsa mphamvu komanso kuchita bwino kwambiri, kuphimba malo ang'onoang'ono komanso mtengo wotsika wokonza.Ndi chida choyenera chowunikira mchenga wouma.
Zinthuzi zimalowa mu bokosi la sieve kudzera pa doko lodyera, ndipo zimayendetsedwa ndi ma injini awiri ogwedezeka kuti apange mphamvu yosangalatsa yoponyera zinthuzo m'mwamba.Nthawi yomweyo, imapita patsogolo mowongoka, ndikuwonetsa zinthu zosiyanasiyana zokhala ndi tinthu tating'ono ting'onoting'ono kudzera pawindo la multilayer, ndikutulutsa kuchokera kumalo omwewo.Makinawa ali ndi mawonekedwe osavuta, kupulumutsa mphamvu komanso kuchita bwino kwambiri, komanso kutsekedwa kwathunthu popanda fumbi kusefukira.
Pambuyo kuyanika, mchenga womalizidwa (madzi nthawi zambiri amakhala pansi pa 0,5%) amalowa pawindo logwedezeka, lomwe limatha kusefa m'magulu osiyanasiyana a tinthu tating'onoting'ono ndikutulutsidwa kuchokera kumadoko otulutsirako malinga ndi zofunikira.Kawirikawiri, kukula kwa nsalu yotchinga ndi 0.63mm, 1.2mm ndi 2.0mm, kukula kwake kwa mauna kumasankhidwa ndikutsimikiziridwa malinga ndi zosowa zenizeni.
