ʻElua mau wili o 800 mm ka anawaena a me 500 mm ka lōʻihi e hoʻohuli ʻia ma nā ʻaoʻao ʻē aʻe e ka mea hoʻemi ʻelua kumu hoʻoiho.Hānai ʻia ka ʻai mai ka ʻaoʻao o luna a ke hana ʻia ka hana ʻoki ʻana i loko o ke āpau i hana ʻia ma waena o nā ʻōwili ʻelua.Hoʻohana nui ʻia ka hoʻohana ʻana i ka ʻili o ka ʻōwili maʻemaʻe ma luna o ka ʻoki ʻana i ka ʻili o ka ʻōwili me kahi nui o ka hana wili.Hoʻokuʻu ʻia ka mea haʻihaʻi e ka umekaumaha.Hōʻike ʻia ka crusher ma ke kaomi ʻana o ka mea i hoʻokahi manawa i ka wā e hele ai i waena o nā ʻōwili ʻelua, no laila ua emi ka pulverization.
Loaʻa i ka roller crusher nā mea maikaʻi o ka hana maʻalahi, paʻa a me ke kaumaha māmā, ka hana hilinaʻi, ka mālama kūpono, a me nā mea ʻē aʻe, a ʻo ka huahana i ʻoki ʻia he ʻano like ʻole ka nui o ka ʻāpana, ka liʻiliʻi liʻiliʻi, a me ka nui o ka huahana maikaʻi (hiki ke haki i lalo o 3 mm).He kūpono ia no ka mālama ʻana i nā mea palupalu a me ka ʻoki ʻana i nā mea viscous palolo.ʻO ka hemahema nui o ka roller crusher ʻo ia kona hiki ke hana haʻahaʻa.
ʻO ke koena pole ka ʻāpana koena o ka poloka kalapona anode prebaked ma hope o ka hoʻohana ʻia ʻana ma ke kelepona electrolytic.ʻO ka nui o ke koena he 1525 o ka nui o ka poloka kalapona anode, a ʻo ka nui o ka ʻāpana o ka poloka i hana ʻia e nā mea hana i luna he 6070 mm (e like me ke ana waiwai ma ka pauku 112).Ma ke aʻo ʻana i kēia pepa, ua helu ʻia ka nui o ka nui o nā ʻāpana e like me nā koi waiwai.
