ʻO nā ʻāpana nui o ka Impact Crusher ʻo nā kī kī a me nā pā hopena, me ka hoʻomaʻamaʻa wela kūikawā, hiki i ka paʻakikī o kā mākou pahu pahu ke hiki i HRC58 ~ HRC63. Hoʻohana nui ka huahana i nā mea kila manganese kiʻekiʻe, no ka laʻana Mn14Cr2, Mn18Cr2, Mn22Cr2 a pēlā aku. Hoʻohana nui ʻia nā pahu puhi a SHANVIM a me nā pā hopena i ka ʻoihana mining, kūkulu, kemika, sima a me ka ʻoihana metallurgical. ʻO kā mākou mau ʻāpana hopena he ola lawelawe 50 ~ 100% lōʻihi ma mua o nā mea i hana ʻia me ka hao chromium kiʻekiʻe.
