ʻO nā ʻāpana ʻaʻahu crusher—me nā papa ʻauwae, nā liner cone, a me nā kaola puhi hopena—ʻo ia nā ʻāpana i hoʻololi pinepine ʻia i nā hana mining a me nā hana aggregate, e helu ana a hiki i ka 30% o nā kumukūʻai mālama makahiki o kahi hale hana wili. ʻAʻole wale ka ʻaʻahu mua e hoʻonui i ka manawa downtime a me nā lilo hoʻololi akā hoʻopilikia pū i nā papa hana hana, e hoʻolilo ana i ka hoʻokele ʻāpana ʻaʻahu i mea koʻikoʻi i ka pono hana. Ke nānā nei kēia ʻatikala i nā ʻano hana ʻaʻahu mua e pili ana i nā ʻāpana crusher a hāʻawi i nā hoʻolālā i hoʻokumu ʻia i nā hōʻike e hoʻolōʻihi i ko lākou ola, e kahakiʻi ana i ka ʻikepili mālama ʻoihana a me nā loina ʻepekema mea.
ʻAʻole he hana maʻamau ka ʻaʻahu ʻana i nā ʻāpana crusher; hoʻokele ʻia e ʻekolu mau ʻano hana koʻikoʻi, kēlā me kēia i pili i nā kūlana hana kikoʻī a me nā waiwai mea. ʻO ka mea i ʻike nui ʻia ʻo iaʻaʻahu ʻāwili, ka mea e hana ʻia i ka wā e ʻānai ai nā ʻāpana paʻakikī, angular (e like me ka granite a i ʻole basalt) i ka ʻili o nā ʻāpana ʻaʻahu, e wehe mālie ana i nā mea. ʻO kēia ʻano hana ke kuleana no ka ʻoi aku o 60% o ka ʻaʻahu mua ʻana i nā papa ʻauwae a me nā liners cone, ʻoi aku hoʻi i nā mea kanu e hana ana i nā ores silica kiʻekiʻe. ʻO ka lua, ʻo iaka ʻaʻahu hopena, i hoʻokumu ʻia e nā kuʻi wikiwiki ma waena o nā mea hānai a me nā ʻāpana e like me nā kaola puhi crusher impact. He mea maʻamau kēia ʻano ʻaʻahu i nā noi hana hou, kahi e hāʻawi ai nā ʻōpala sima a me nā ʻōpala kūkulu i nā ukana haʻalulu hou. ʻO ka hope loa,ʻaʻahu luhikū mai ke kaumaha cyclic: i ka wā e pelu ai nā ʻāpana crusher ma lalo o ka hoʻouka mau ʻana, hana ʻia nā micro-cracks ma luna o ka ʻili, a laila e alakaʻi ana i ka spalling mea. ʻO nā crushers cone, e hana ana ma lalo o nā ikaika compression kiʻekiʻe, ua maʻalahi loa i ka luhi ʻana ma nā liners mantle a me concave.
ʻO ka hoʻomaopopo ʻana i kēia mau ʻano hana ka hana mua i ka hoʻolōʻihi ʻana i ke ola o ka ʻāpana komo, akā pono ka hana kūpono i ka hui pū ʻana o ke koho ʻana i nā mea, ke kau ʻana kūpono, a me ka mālama pono.
Koho meaʻo ia ke kumu o ke kūpaʻa ʻana i ka ʻaʻahu. No ka laʻana, ʻo Mn13Cr2 kahi koho kūpono no nā noi abrasive haʻahaʻa a waena, e like me ka wāwahi ʻana i ka limestone, ma muli o kona mau waiwai paʻakikī e hoʻoikaika ana i lalo o ka hopena. I ka hoʻohālikelike ʻana, hāʻawi ʻo Mn18Cr2—me ka nui o ka chromium—i ke kūpaʻa abrasive maikaʻi loa no nā mea silica kiʻekiʻe e like me ka granite, e kūpono ai no ka hoʻohana lōʻihi i nā wahi mining koi. ʻO ka hoʻohālikelike ʻana i ka mea i ka paʻakikī a me ka abrasiveness o ka mea hānai hiki ke hōʻemi i nā helu ʻaʻahu ma 20-30%, e like me ka ʻikepili mai ka International Mining and Resources Conference (IMARC).
Hoʻokomo kūpono a me ka mālama maʻamauhe mea koʻikoʻi like. ʻOiai nā mea paʻa loa e hāʻule mua inā hoʻokomo hewa ʻia. No nā mea wili ʻāwae, ʻo ka hōʻoia ʻana ua kūlike nā papa ʻāwae me ka hakahaka like e pale ai i ka ʻaʻahu like ʻole a hōʻemi i ke kaumaha ma ka hui papa hoʻololi. No nā mea wili ʻāwae cone, ʻo ka nānā mau ʻana o ka hakahaka mantle-to-concave a me ka torque ma nā bolts paʻa hiki ke hoʻopau i ka misalignment e hoʻoulu ai i ka luhi. Eia kekahi, ʻo ka lubrication o nā pivot points a me ka nānā pinepine ʻana o ka mānoanoa o ka ʻāpana ʻaʻahu (me ka hoʻohana ʻana i ka hoʻāʻo ultrasonic a i ʻole calipers) e ʻae i nā hui e hoʻonohonoho i nā pani ma mua o ka hiki ʻana mai o ka hāʻule ʻana, e hoʻemi ana i ka downtime i hoʻolālā ʻole ʻia.
Hoʻonui hanaHoʻonui hou aku i ka lōʻihi o ka ʻāpana ʻaʻahu. ʻO ka kaohi ʻana i ka nui o ka hānai a me ka hoʻolaha ʻana e hōʻemi ana i nā ikaika hopena: no ka laʻana, ʻo ka hoʻohana ʻana i kahi mea hānai haʻalulu e hoʻolaha like i nā mea i loko o ke keʻena crusher e pale aku i ka ʻaʻahu kūloko ma kekahi ʻaoʻao o ka papa ʻauwae. ʻO ka nānā mua ʻana i nā mea hānai e wehe i nā mea maikaʻi (nā ʻāpana liʻiliʻi ma mua o 10mm) e hōʻemi pū i ka ʻaʻahu abrasive, no ka mea, hana nā mea maikaʻi ma ke ʻano he mea wili ma waena o ka ʻāpana ʻaʻahu a me nā pōhaku nui. ʻO ka hope loa, ʻo ka hoʻoponopono ʻana i nā hoʻonohonoho crusher—e like me ka hoʻonohonoho ʻaoʻao pani (CSS) i loko o nā crushers cone—e kūlike me ka nui o ka huahana i makemake ʻia e pale aku i ka nui o ka wāwahi ʻana, kahi e hoʻonui ai i ke kaumaha pono ʻole ma nā liners.
I ka hopena, ʻo ka hoʻolōʻihi ʻana i ke ola o ka ʻāpana crusher ʻaʻole ia he mea e koho ai i ka mea "paʻakikī loa", akā, ʻo ka hoʻohana ʻana i kahi ala holoʻokoʻa e pili ana i nā ʻano hana i kēlā me kēia pae o ka hana. Ma ke koho ʻana i nā mea i hana ʻia no nā ʻano hānai, ka hoʻokō ʻana i nā protocols hoʻonohonoho a me ka mālama pono, a me ka hoʻomaikaʻi ʻana i nā palena hana, hiki i nā luna o nā hale hana ke hōʻemi nui i nā kumukūʻai mālama a hoʻomaikaʻi i ka hilinaʻi hana. No nā ʻoihana ma ka ʻoihana crusher, ʻo ka hoʻopukapuka kālā ʻana i ka lōʻihi o ka ʻāpana ʻaʻole ia he ana mālama kālā - he ʻanuʻu hoʻolālā ia i nā hana hoʻomau a maikaʻi.
