Mukugadzirwa kwemapepa emazuva ano, iyo inonyanya kushandiswa yakasvibiswa mapepa uye mhandara pulp, asi dzimwe nguva marara mapepa uye virgin pulp hazviwanikwe mune imwe nzvimbo, zvakaoma kuwana kana kudhura zvakanyanya kutenga, munyaya iyi, mugadziri anogona kufunga nezve shandisai mashanga egorosi sechinhu chisina kubikwa kugadzira mapepa, mashanga egorosi chinhu chakajairika kubva mukurima, chiri nyore kuwana, chizere muhuwandu uye chinodhura zvishoma.
Zvichienzaniswa nefiber yehuni, faibha yemashanga egorosi yakanyanya kunyorova uye haina simba, hazvisi nyore kuchena, saka kazhinji, mashanga egorosi anonyanya kushandiswa kugadzira bepa rinoputika kana marata, chimwe chigayo chakavhenganiswa gorosi. virgin pulp kana marara bepa kugadzira yakaderera mhando yematishu bepa kana hofisi bepa, asi pepa rinoputika kana pepa remarara rinoonekwa sechinonyanya kufarirwa chigadzirwa, nekuti maitiro ekugadzira ari nyore uye mutengo wekugadzira wakaderera.
Kubuditsa bepa, mashanga egorosi anofanira kutanga atemwa, kureba 20-40mm kunodiwa, zviri nyore kuti hundi hutakurwe kana kusanganiswa nemishonga yekubikisa, muchina wekucheka mashanga egorosi unokumbirwa kuita basa, asi neshanduko indasitiri yemazuva ano yekurima, gorosi rinowanzo kukohwewa nemichina, mune iyi kesi, muchina wekucheka haufungidzirwe zvakakosha.Mushure mekucheka, uswa hwegorosi huchaendeswa kuti husanganise nemakemikari ekubikisa, caustic soda yekubika nzira inowanzoshandiswa mukuita uku, kuderedza mari yekubika, mvura yedombo reraimu inogonawo kutariswa.Mushure mokunge mashanga egorosi akanyatso kusanganiswa nemishonga yekubika, ichaendeswa kune spherical digester kana pasi pevhu yekubikira dziva, nokuda kwekubika zvishoma, pasi pevhu yekubikira dziva rinokurudzirwa, kuvakwa kwebasa rehurumende, mari shoma, asi yakaderera.Kune yakakwirira yekugadzira kugona, inofanirwa kufunga nezve kushandisa spherical digester kana contiguous yekubika mudziyo, mukana wekubika kubika, asi hongu, mutengo wemidziyo ungakwira zvakare.Iyo yepasi pevhu yekubikira dziva kana spherical digester yakabatana nemhepo inopisa, nekuwedzera kwekushisa mumudziyo kana tangi uye kusanganiswa kwekubika mumiriri, lignin uye fiber zvichaparadzaniswa mumwe nemumwe.Mushure mekubika, huswa hwegorosi huchaburutswa kubva mumudziyo wekubikira kana tangi yekubikira kuenda mubhini rekuvhuvhuta kana sediment tank yakagadzirira kuburitsa faibha, muchina unowanzo shandiswa mushina wekubvoura, muchina wekugezesa pulp kana bivis extruder, kusvika ipapo huswa hwegorosi. fiber ichave yakanyatso kucheneswa, mushure mekuita kwekunatsa nekuongorora, ichashandiswa kugadzira pepa.Kunze kwekugadzira mapepa, gorosi mashanga faibha inogona zvakare kushandiswa kugadzira tireyi yehuni kana kuumba tirayi yezai.
