Muchikamu chekudhinda cheindasitiri yemazuva ano yepepa, sikirini inodedera yemuchina wepepa chishandiso chikuru chekuchenesa nekuongorora pulp. Kushanda kwayo kunokanganisa zvakananga kunaka kwekugadzira mapepa uye kushanda zvakanaka, uye inoshandiswa zvakanyanya muchikamu chekugadzirisa pulps dzakasiyana-siyana dzakadai sepulp yehuni uye pulp yepepa yakaraswa.

Panyaya yekushanda, sikirini inodedera inogadzira kudedera kwakananga kuburikidza nemota yemagetsi ichityaira block isina kusimba, zvichiita kuti furemu yesikirini ifambise mesh yesikirini kuti iite kufamba kwakakwirira, kudiki-diki kweamplitude. Kana pulp ikapinda mumuviri wesikirini kubva panzvimbo yekudyisa, pasi pesimba rekudedera, mafiber akakodzera (pasi pehukuru) anosangana nezvinodiwa nemaitiro anopfuura nepakati pemaburi emasikirini uye anopinda mumaitiro anotevera; nepo masara epulp, tsvina, nezvimwewo (zvakawandisa) zvichiendeswa kunzvimbo yekubuditsa slag nenzira yakakombama yenzvimbo yesikirini uye zvichiburitswa, nokudaro zvichipedzisa kupatsanurwa nekucheneswa kwepulp.

Panyaya yekugadzirwa kwechivako, sikirini inodedera inonyanya kuumbwa nezvikamu zvishanu zvakakosha: chekutanga,muviri wechidzitiro, iyo inoshanda senzvimbo huru yekutakura nekuparadzanisa pulp, inonyanya kugadzirwa nesimbi isingatsvedzi kuti ive nechokwadi chekuti ngura haipindi; chechipiri,sisitimu yekudedera, kusanganisira mota, eccentric block uye spring inobvisa kuvhunduka, pakati payo spring inobvisa kuvhunduka inogona kuderedza zvinobudirira kukanganiswa kwekuzunguzika pahwaro hwemidziyo; chechitatu,mesh yechidzitiro, sezvo chinhu chikuru chekusefa, mesh yakarukwa nesimbi isina ngura, mesh yakaboorwa, nezvimwewo zvinogona kusarudzwa zvichienderana nerudzi rwepulp, uye nhamba yayo ye mesh inofanira kutsanangurwa pamwe chete nezvinodiwa zvemhando yepepa; chechina,mudziyo wekudyisa nekuburitsa, nzvimbo yekupinza chikafu inowanzo kuve nechinhu chinodzivira kuti isakanganiswe zvakananga nepulp pa screen mesh, uye nzvimbo yekubuditsa mvura inofanira kuenzana nekukwirira kwekudya kwemidziyo inotevera; chechishanu,mudziyo wekutumira, mamwe mascreen makuru ekudedera ane nzira yekuderedza kumhanya kuti adzore nemazvo frequency yekudedera.

Mukushanda kwayo, sikirini inodedera ine zvakanakira zvakakosha: chekutanga, kushanda zvakanaka kwekuchenesa, kudedera kwepamusoro-soro kunogona kudzivirira kuvharika kwemeshi yechidzitiro, zvichiita kuti mwero wepasi pefiber ugare wakadzikama pamusoro pe95%; chechipiri, kushanda kuri nyore, frequency yekudedera inogona kuchinjwa nyore nyore nekugadzirisa kumhanya kwemota kuti ienderane nehuwandu hwakasiyana hwepulp (kazhinji huwandu hwekurapa i0.8%-3.0%); chechitatu, mutengo wakaderera wekugadzirisa, sikirini inobvisa dhizaini nekukurumidza, uye nguva yekutsiva inogona kupfupikiswa kusvika pasi pemaminitsi makumi matatu, zvichideredza nguva yekushanda kwemidziyo.

Nekuvandudzwa kweindasitiri yemapepa ku "kushanda zvakanaka, kuchengetedza simba uye kuchengetedzwa kwezvakatipoteredza", sikirini inodedera inogara ichivandudzwa. Semuenzaniso, sisitimu yekudzora frequency conversion yakangwara inoshandiswa kugadzirisa otomatiki maparamita ekudedera, kana kuti chimiro che screen mesh chinogadziriswa kuti chivandudze kurongeka kwezvikamu zvakanaka, zvichizadzisa zvinodiwa zvemapepa emhando yepamusoro uye mapepa akakosha ekugadzira pulp yakachena.
