Kwicandelo lokucoca kwishishini lanamhlanje lephepha, isikrini sokungcangcazela somatshini wephepha sisixhobo esiphambili sokucoca nokuhlola i-pulp. Ukusebenza kwayo kuchaphazela ngokuthe ngqo umgangatho wokwenza iphepha kunye nokusebenza kakuhle kwemveliso, kwaye isetyenziswa kakhulu kwicandelo lonyango lwangaphambi konyango lwe-pulps ezahlukeneyo ezifana ne-pulp yomthi kunye ne-pulp yephepha elilahliweyo.

Ngokwemigaqo yokusebenza, isikrini esingcangcazelayo senza ukungcangcazela kwicala elithile ngemoto yombane eqhuba ibhloko engaqhelekanga, nto leyo eyenza isakhelo sesikrini siqhube i-screen mesh ukuze senze intshukumo ephindaphindayo, enobukhulu obuncinci. Xa i-pulp ingena emzimbeni wesikrini isuka kwindawo yokungena, phantsi kwesenzo sokungcangcazela, iifayibha ezifanelekileyo (ezingaphantsi kobukhulu) ezihlangabezana neemfuno zenkqubo zidlula kwizithuba ze-screen mesh kwaye zingene kwinkqubo elandelayo; ngelixa iintsalela ze-pulp, ukungcola, njl.njl. (ezingaphezulu kobukhulu) zithuthwa ziye kwindawo yokukhupha i-slag ecaleni kwendlela ethe tye yomphezulu wesikrini kwaye zikhutshwe, ngaloo ndlela kugqityezelwa ukwahlulwa kunye nokucocwa kwe-pulp.

Ngokuphathelele uyilo lwesakhiwo, isikrini esingcangcazelayo senziwe ikakhulu ngamacandelo amahlanu abalulekileyo: okokuqala,umzimba wesikrini, esebenza njengomzimba oyintloko wokuthwala nokwahlula i-pulp, uninzi lwayo lwenziwe ngentsimbi engagqwali ukuqinisekisa ukumelana nokugqwala; okwesibini,inkqubo yokungcangcazela, kuquka injini, ibhloko engaqhelekanga kunye nentwasahlobo efunxa ukubetheka, apho intwasahlobo efunxa ukubetheka inokunciphisa ngempumelelo impembelelo yokungcangcazela kwisiseko sesixhobo; okwesithathu,umnatha wesikrini, njengoko into ephambili yokucoca, i-mesh eyolukiweyo yentsimbi engagqwaliyo, i-mesh ebhoboziweyo, njl.njl. inokukhethwa ngokohlobo lwe-pulp, kwaye inani layo le-mesh kufuneka limiselwe ngokudibeneyo neemfuno zohlobo lwephepha; okwesine,isixhobo sokondla nokukhupha itshaja, indawo yokungena kwesondlo idla ngokuxhotyiswa nge-deflector ukuthintela impembelelo ethe ngqo yepulp kwi-screen mesh, kwaye indawo yokukhupha kufuneka ilingane nobude be-feed yezixhobo ezilandelayo; okwesihlanu,isixhobo sokudlulisa, ezinye izikrini ezinkulu zokungcangcazela zixhotyiswe ngendlela yokunciphisa isantya ukulawula ngokuchanekileyo isantya sokungcangcazela.

Xa isetyenziswa ngendlela ebonakalayo, isikrini esingcangcazelayo sineengenelo ezibalulekileyo: okokuqala, ukusebenza kakuhle kokuhlanjululwa, ukungcangcazela okuphindaphindekayo kunokuthintela ngempumelelo ukuvaleka kwe-screen mesh, ukuqinisekisa ukuba izinga lokudlula kwefayibha lihlala lingaphezulu kwe-95%; okwesibini, ukusebenza okulula, i-vibration frequency inokutshintshwa ngokulula ngokulungelelanisa isantya semoto ukuze ivumelane noxinzelelo lwe-pulp olwahlukeneyo (ngesiqhelo uxinzelelo lonyango yi-0.8%-3.0%); okwesithathu, iindleko eziphantsi zokulungisa, i-screen mesh isebenzisa uyilo olukhawulezayo lokuqhawula, kwaye ixesha lokutshintsha linokufuthwa libe ngaphantsi kwemizuzu engama-30, okunciphisa ixesha lokungasebenzi kwezixhobo.

Njengoko ishishini lephepha liphuhliswa lijonge "ekusebenzeni okuphezulu, ukonga amandla kunye nokukhuselwa kwendalo", isikrini sokungcangcazela naso sihlala siphuculwa. Umzekelo, inkqubo yokulawula ukuguqulwa kwamaza akrelekrele iyasetyenziswa ukuze kufezekiswe uhlengahlengiso oluzenzekelayo lweeparamitha zokungcangcazela, okanye isakhiwo se-screen mesh silungiselelwe ukuphucula ukuchaneka kokuhluzwa kwezinto ezincinci, oku kuhlangabezana neemfuno ezingqongqo zephepha eliphezulu kunye nemveliso ekhethekileyo yephepha ukuze kucoceke i-pulp.
