Ko ngā wāhanga pakaru o te mīhini kuru—tae atu ki ngā pereti kauae, ngā arai kōne, me ngā pae pupuhi pānga—koinei ngā wāhanga e tino whakakapia ana i roto i ngā mahi keri me te kohikohinga, tae atu ki te 30% o ngā utu tiaki ā-tau o te tipu kuru. Ehara i te mea ka whakanui ake te pakaru wawe i te wā kore mahi me ngā utu whakakapinga engari ka whakararuraru hoki i ngā kaupapa whakaputa, ka waiho te whakahaere wāhanga pakaru hei mea nui ki te whai huatanga o te mahi. E tūhuratia ana e tēnei tuhinga ngā tikanga pakaru tuatahi e pā ana ki ngā wāhanga kuru, ā, e whakarato ana i ngā rautaki e ahu mai ana i ngā taunakitanga hei whakaroa i tō rātou roa, e whakamahi ana i ngā raraunga tiaki ahumahi me ngā mātāpono pūtaiao rauemi.
Ehara te pakaru o ngā wāhanga kuru i te tukanga matapōkere; e toru ngā tikanga matua e ārahihia ana, ia tikanga e hono ana ki ngā āhuatanga mahi me ngā āhuatanga rauemi. Ko te mea tino kitea kote kakahu whakakoi, ka puta ina waruhia ngā matūriki mārō, koki (pērā i te karāneti, te pātara rānei) ki te mata o ngā wāhanga pakaru, ka tangohia mārire ngā rauemi. Ko tēnei tikanga te take o te neke atu i te 60% o te pakaru wawe i roto i ngā pereti kauae me ngā raina kōne, inā koa i roto i ngā tipu e tukatuka ana i ngā konganuku silica nui. Tuarua kote kakahu pānga, i puta mai i ngā tukinga tere-tere i waenga i ngā rauemi whāngai me ngā wāhanga pērā i ngā pae pupuhi pakaru pānga. He mea noa tēnei momo kakahu i roto i ngā tono hangarua, i reira ka tukuna e ngā para raima me ngā para hangahanga ngā kawenga ru. Hei whakamutunga,te kakahu ngengeka puta mai i te ahotea hurihuri: i te mea ka piko ngā wāhanga o te kuru i raro i te kawenga tonu, ka puta ngā kapiti moroiti ki te mata, ā, ka mutu ka pakaru ngā rauemi. Ko ngā kuru kōne, e mahi ana i raro i ngā kaha pēhanga teitei, he tino ngāwari ki te kakahu ngenge i runga i ngā arai mantle me ngā arai concave.
Ko te mārama ki ēnei tikanga te taahiraa tuatahi ki te whakaroa i te roa o te ora o te wāhanga kakahu, engari ko te mahi tūturu me whai huinga o te whiriwhiri rauemi, te tāutanga tika, me te tiaki wawe.
Kōwhiringa rauemiKo te pūtake tēnei o te ātete ki te kakahu. Hei tauira, he kōwhiringa utu-pai te Mn13Cr2 mō ngā tono whakakoi iti ki te reo, pērā i te kuru i te kōhatu, nā ōna āhuatanga whakapakeke mahi ka kaha ake i raro i te pānga. He rerekē, ko te Mn18Cr2—he nui ake te ihirangi chromium—he ātete whakakoi pai ake mō ngā rauemi silica nui pērā i te granite, he mea tino pai mō te whakamahinga roa i roto i ngā taiao keri uaua. Mā te whakataurite i te rauemi ki te pakeke me te kaha whakakoi o te rauemi whāngai ka taea te whakaiti i ngā reiti kakahu mā te 20-30%, e ai ki ngā raraunga mai i te International Mining and Resources Conference (IMARC).
Te tāutanga tika me te tiaki auauHe rite tonu te hiranga. Ahakoa ngā rauemi tino pakari ka pakaru wawe tonu mēnā ka tāuta hē. Mō ngā kuru kauae, mā te whakarite kia rite te tūnga o ngā pereti kauae ki te mokowā āputa ōrite ka ārai i te pakaru kore taurite, ā, ka whakaiti i te ahotea i runga i te huihuinga pereti takahuri. Mō ngā kuru kōne, mā te tirotiro auau i te āputa mantle-ki-concave me te taipana i runga i ngā pūtu pupuri ka taea te whakakore i te tūnga hē e puta ai te pakaru ngenge. Hei tāpiri, mā te whakahinuhinu i ngā pūwāhi pivot me te tirotiro ā-wā i te matotoru o te wāhanga pakaru (mā te whakamahi i te whakamātautau ultrasonic, i ngā calipers rānei) ka taea e ngā tīma te whakarite whakakapinga i mua i te pakaru kino, ka whakaiti i te wā kore mahi i whakaritea.
Te arotautanga whakahaereka whakarei ake i te roa o te wā e mau ana te wāhanga. Mā te whakahaere i te rahi me te tohatoha o te whāngai ka whakaiti i ngā kaha pānga: hei tauira, mā te whakamahi i tētahi whāngai wiri hei tohatoha ōrite i ngā rauemi ki roto i te rūma kuru ka ārai i te mau o te taha kotahi o te pereti kauae. Mā te tirotiro-mua i ngā rauemi whāngai hei tango i ngā mea angiangi (ngā matūriki iti iho i te 10mm) ka whakaitihia hoki te mau o te mea whakakoi, nā te mea he reo huri ngā mea angiangi i waenga i te wāhanga mau me ngā toka nunui ake. Hei whakamutunga, mā te whakarerekē i ngā tautuhinga kuru—pērā i te tautuhinga taha kati (CSS) i roto i ngā kuru kōne—kia ōrite ki te rahi hua e hiahiatia ana ka karohia te kuru nui rawa, ka whakanui ake i te ahotea koretake ki runga i ngā raina.
Hei whakamutunga, ko te whakaroa i te roa o te wā e mau ana te wāhanga kuru ehara i te mea mā te whiriwhiri i te rauemi "tino uaua", engari mā te whakamahi i tētahi huarahi whānui e aro ana ki ngā tikanga kakahu i ia wāhanga o te mahi. Mā te whiriwhiri i ngā rauemi e hāngai ana ki ngā āhuatanga whāngai, te whakatinana i ngā tikanga tāutanga me te tiaki pakari, me te arotau i ngā tawhā mahi, ka taea e ngā kaiwhakahaere tipu te whakaiti i ngā utu tiaki me te whakapai ake i te pono o te whakaputa. Mō ngā pakihi i roto i te umanga kuru, ko te haumi ki te roa o te wā e mau ana te wāhanga kuru ehara i te mea he mahi penapena utu noa iho—he taahiraa rautaki ki ngā mahi pumau, whai hua.
