Umshini wokugaya wumshini omusha wokugaya owenziwe maphakathi no-1980s Ubuchwepheshe obusha bokuqothula nokugaya ikakhulukazi obenziwe ngayo bunomphumela omuhle ekongeni amandla, futhi wathola ukunakwa okukhulu okuvela embonini yamakhemikhali omhlaba jikelele. Sekuwubuchwepheshe obusha ekuthuthukiseni ubuchwepheshe bokugaya. Umshini usebenzisa isimiso sokusebenza sokusetshenziswa kwamandla okuphansi kwengcindezi yempahla ephezulu futhi usebenzisa imodi yokusebenza yenhlayiya eyodwa echotshozwa ngamaqembu. Ngemuva kokukhishwa kwengcindezi ephezulu kwezinto eziqhekekile (ingcindezi esendaweni yengcindezi yemishini icishe ibe yi-15 MPa, ubukhulu bezinhlayiya bento buyancipha ngokushesha.Ukuqukethwe kwempuphu engaphansi kuka-0.08mm kufinyelela kuma-20% ~ 30%, kanti impahla engu-2mm ifinyelela ngaphezu kwama-70%, futhi kunenqwaba yemifantu kuzo zonke izinto ezikhishiwe, ukuze kuthi inqubo elandelayo yokugaya, ukusetshenziswa kwamandla okudingekayo kuncishiswe kakhulu.Ngokuya kwedatha efanelekile yakwamanye amazwe kanye nesipiliyoni sethu esiwusizo, uma kuqhathaniswa ohlelweni lokugaya olungafakelwe umshini wokugaya, uhlelo lokugaya olufakwe i-roller cindezela lungakhuphula umkhiqizo ngo-50% ~ 200%, ukusetshenziswa kwamandla iyunithi ngayinye kunganciphisa ngo-20% ~ 35%. Ngaphezu kwalokho, ngenxa yokugqokwa okuncane kwe-roller, ukusetshenziswa kwamandla esigayweni ngasinye kuncishisiwe kakhulu.Ngaleso sikhathi, umsindo nothuli lwezinto zokusebenza kuphansi, okwenze ngcono indawo yokusebenza futhi kukhombisa ngokugcwele izinzuzo zayo ezinhle kwezomnotho nezenhlalo.

Umzimba oyinhloko wemishini ngamaroli amabili ajikelezayo ajwayelekile, izinto zokwakha ezinomkhuhlane zifakwa emgqonyeni onesisindo ohlonyiswe amaseli wokulayisha, nokudlula kudivayisi yokudla yomshini wokucindezela, futhi ifakwa ngosayizi ababili abafanayo, amasondo wokujikeleza ahlobene, i-roller idonsela izinto esikhaleni se-roller, okwamanje i-roller cindezela umfutho ophakeme ezintweni ukuze uzenze ikhekhe lezinto ezijiyile, ekugcineni iwele phansi isuka esikhaleni esiphakathi kwama-roller amabili, idlule ku-chute wokukhipha, ekhishwe yimishini ehambisa futhi izinto ziyahlakazeka futhi zigaywe esigabeni senqubo esilandelayo.
