Umshini wephepha we-A4 okuwumugqa wokwenza iphepha nawo unezigaba ezahlukene;
1- Ingxenye yokugeleza kwendlela elungisa ukugeleza kwengxube ye-pulp elungile ukwenza iphepha elinesisindo esinqunyiwe.Isisekelo sesisindo sephepha yisisindo semitha yesikwele ngamagremu.Ukugeleza kwe-pulp slurry ehlanjululwayo izohlanzwa, ihlolwe ezikrinini ezifakiwe futhi ithunyelwe ku-head box.
2- Ibhokisi lekhanda lendlale ukugeleza kwe-pulp slurry ngokufana kakhulu phakathi kobubanzi bocingo lomshini wephepha.Ukusebenza kwebhokisi lekhanda kunqunywa ekuthuthukisweni kwekhwalithi yomkhiqizo wokugcina.
3- Ingxenye Yocingo;I-Pulp slurry ikhishwa ngokufanayo ocingweni olunyakazayo futhi ucingo oluya ngasekugcineni kwengxenye yocingo, cishe u-99% wamanzi uyakhishwa kanye newebhu emanzi enokoma okungaba ngu-20-21% idluliselwe esigabeni sokucindezela. ukuqhubeka nokukhipha amanzi.
4- Cindezela Isigaba;Isigaba sabezindaba sichitha iwebhu ngokuqhubekayo ukuze ifinyelele ukoma okungama-44-45%.Inqubo dewatering in mechanical ngaphandle kokusebenzisa amandla ezishisayo.Isigaba sabezindaba ngokuvamile sisebenzisa ama-nips angu-2-3 kuye ngobuchwepheshe bokucindezela nokucushwa.
5- Ingxenye Yokomisa: Ingxenye yokomisa yomshini wephepha lokubhala, wokuphrinta kanye nokukopisha iklanywe ngezigaba ezimbili, umshini wokomisa ngamunye kanye nesomiso ngasinye kusetshenziswa amasilinda ambalwa okomisa kusetshenziswa isitimu esigcwele njengendlela yokushisisa. iwebhu emanzi yomile yaze yome ngo-92% futhi lewebhu eyomile izoba ngaphezu kuka-2-3 amagremu/skwele mitha/uhlangothi lwesitashi sephepha esilungiswe ekhishini leglue.Iwebhu yephepha ngemva kokulinganisa izoba namanzi angaba ngu-30-35%.Le webhu emanzi izophinde yomiswe endaweni yokomisa ibe ngu-93% elungele ukusetshenziswa ekugcineni.
6‐ Ikhalenda: Iphepha eliphuma endaweni yokomisa alikulungele ukuphrinta, ukubhala nokukopishwa ngenxa yokuthi indawo yephepha ayibushelelezi ngokwanele.Ikhalenda izonciphisa ubulukhuni bephepha futhi ithuthukise ukusebenza kwalo emishinini yokuphrinta kanye nokukopisha.
7 - Ukuphefumula;Ekupheleni komshini wephepha, iwebhu eyomile yephepha ilinyazwa nxazonke zensimbi esindayo efinyelela kumamitha angu-2.8 ububanzi.Iphepha elikulo mqulu lizoba amathani angama-20.Lo mshini we-jumbo paper roll winding ubizwa ngokuthi i-pope reeler.
8- Ukubuyisela emuva;Ububanzi bephepha ku-master paper roll cishe ububanzi bocingo lomshini wephepha.Lo mqulu wephepha owungcweti udinga ukusikwa ngobude nangobubanzi njengoba kuyalelwe ngokusetshenziswa kokugcina.Lona umsebenzi wesibuyisela emuva ukuhlukanisa i-jumbo roll kumaroli amancane.
