RŌRA WHIRI PĒHANGA TEITEI PŪTAKI TAKITAHI
Whānuitanga o te tono
Ko te rōra huri pēhanga teitei kotahi-puku he mea hanga motuhake hei huri i ngā konganuku sima, te paru kohuke, ngā konganuku maitai me ētahi atu kia rite ki ngā kirikiri iti, hei kuru rawa i ngā kohuke whakarewa (ngā konganuku rino, ngā konganuku konupora, ngā konganuku parahi, ngā konganuku mata-konutea, ngā konganuku vanadium me ētahi atu) me te huri i ngā kohuke kore-whakarewa (ngā konganuku waro,
te feldspar, te nepheline, te dolomite, te kōhatu ā-papa, te quartz, me ētahi atu) hei paura.
Hanganga me te Mātāpono Mahi
◆Kauwhata Mātāpono Mahi
Ka whakamahia e te rōra huri pēhanga teitei kotahi-taraiwa
te mātāpono huri o te whakaputanga rauemi whakahiato.
Ko tētahi he rōra tūmau, ko tētahi he rōra nekeneke.
Ka huri ngā roera e rua ki te taha ke i te tere kotahi.
Ka tomo mai ngā rauemi mai i te whakatuwheratanga whāngai o runga,
ā, ka hurihia nā te pehanga nui i roto i te āputa o ngā rōra e rua, ka tukuna mai i raro.
◆Wāhanga taraiwa
Kotahi anake te puku motuka e hiahiatia ana,
ka tukuna te mana mai i te rōra tūmau ki te rōra nekeneke mā te pūnaha taputapu,
kia tino tukutahi ai ngā roera e rua, kia kore ai he waku reti.
Ka whakamahia katoatia te mahi mō te whakaputa rauemi,
ā, he nui te tere whakamahinga pūngao, e penapena ana i te 45% o te hiko ki te whakaritea ki te rōra huri pēhanga teitei tikanga.
◆Pūnaha pēhanga
Mā te pūnaha pēhanga miihini o te puna whakakotahi ka kore e taea te neke te huri i te rōra.
Ina tomo mai he mea rino ke,
ka hoki whakamuri tika te pūnaha pēhanga puna, ka tauhohe i te wā tika, kia eke te tere mahi ki te 95%;
Ahakoa e taea ai te karo i te hurihanga pēhanga teitei tuku iho, me tukuna te hinu waipēhi mā te paipa hei whakamama i te pēhanga.
Ka whakaroa te mahi, ka pā kino pea ki te mata hurihuri, ka hē rānei te pūnaha waipēhi.
◆Mata hurihuri
Ko te mata o te roera he mea whakarewa ki te rauemi whakarewa ātete-kākahu koranu, ā, ka taea e te pakeke te tae ki te HRC58-65; ka whakatikatika aunoa te pēhanga me te rauemi,
e kore e tutuki noa i te kaupapa o te huri, engari e tiaki ana hoki i te mata o te roera;
Ka mahi tahi te rōra neke me te rōra tūmau, me te kore he waku reti.
Nō reira, he roa ake te ora o te mata o te rōra i tērā o te rōra huri pēhanga teitei tikanga.
Ngā Āhuatanga Hangarau Matua
◆ Teitei o te Whai Hua o te Mahi. Ki te whakatauritea ki ngā taputapu kuru tuku iho, ka piki ake te kaha tukatuka mā te 40 - 50%.
Ka taea e te kaha tukatuka mō te PGM1040 te eke ki te 50 - 100 tana ia hāora, me te mana 90kw anake.
◆ He iti te whakapaunga pūngao. E ai ki te tikanga taraiwa hurihuri kotahi, kotahi noa te motuka e hiahiatia ana hei taraiwa.
He iti rawa te whakapaunga hiko. Ki te whakatauritea ki te HPGR puku rua tuku iho, ka taea e ia te whakaiti i te whakapaunga hiko mā te 20~30%.
◆ He kounga pai, ātete ki te kakahu. Kotahi anake te motuka e taraiwa ana, he tino pai te mahi tukutahi o ngā roera e rua.
He pai te kounga o ngā rōra ātete-kakahu, he ngāwari hoki te tiaki, nā te mea he ātete-kakahu ngā mata whakarewa.
◆ Tere Whakahaere Teitei: ≥ 95%. Mā te hoahoa pūtaiao, ka taea te pēhanga i ngā taputapu mā te rōpū puna pēhanga teitei.
Ka taea te whakarite aunoa i te pēhanga mahi kia rite ki te pēhanga o te rōpū puna. Kāore he wāhi hapa.
◆ Aunoatanga teitei me te whakatikatika ngāwari. Ki te kore he pūnaha waipēhi, he iti te tere o te hapa
◆ Ko te mata o te rōra he mea whakarewa ki te rauemi whakarewa ātete-kakahu koranu, he pakeke teitei, he ātete-kakahu pai hoki;
Ko te pēhanga ki te puna i ahu mai i te kaha tauhohenga o te rauemi, ā, he taurite tonu te pēhanga,
e kore e tutuki noa i te kaupapa o te kuru,
engari ka tiakina hoki te mata o te takai; ko te takai neke me te takai tūmau he mea hono, he mea taraiwa hoki e te pūnaha taputapu,
ā, ka tino tukutahitia te tere, kia kore ai e paheke te waku i waenga i te rauemi me te mata o te roera.
Nō reira, he roa ake te ora o te mahi i tō te puku takirua HPGR.
◆ He hanganga kiato, he iti hoki te wāhi o te papa.

TE WHAKATAURITE I WAENGANUI I TE HPGR PŪTAKI TAKITAHI ME TE HPGR NOA
TE TŪTOHI RERA O TE TUKANGA WHAKAMUTUNGA I MUA I TE WHIRI O TE PUKA TAKITAHI HPGR
Te huri-mua i te sima, te para o te konganuku me te para maitai "He nui ake te kuru me te iti o te huri, whakakapia te huri ki te kuru", arā, ko te huri-mua, kua noho hei hangarau matua mō te tukanga whakaputa mira paipa hei whakanui ake i te whakaputanga me te whakaiti i te whakapaunga hiko. Hei taputapu penapena hiko i mua i te huri-mua tino matatau, ka taea e te HPGR puku-kotahi te kuru i ngā rauemi ki te -4mm, ki te -0 .5mm rānei, neke atu i te 30% o ēnei 0 .08mm. Ka taea te whakanui ake i te kaha o te mira pōro e whakamahia ana mā te 50~100%, ā, ka taea te whakaiti i te whakapaunga mana huri pūnaha mā te 15~30%.
TE TŪTOHI RERANGA O TE TUKANGA WHAKAKUKU TINO PAI O TE KOHUKE WHAKAKONO ME TE PUKA KOTAHI HPGR
Te Pakaru Tino Pai o te Kohuke Whakarewa
Ina haere ngā kohuke mā roto i te āputa i waenganui i ngā porotaka e rua, ka kuruhia kia rite ki ngā matūriki angiangi o te -5 mm, -3 mm rānei, me te nui o te paura mā te kaha pēhanga teitei. Nā te ngoikore o te kaha here o te hononga i waenganui i te kohuke whai hua me te gangue, ka ngāwari te puta o te whati ngenge, te pakaru iti rānei me te ahotea o roto. Ka tino wehea tetahi wāhanga o te hononga.
Nā te nui o te paura pai e tukuna ana mai i te HPGR, me te meka e kuruhia ana ngā kohuke i te mata wehewehe, ki te whakaritea ki te kuru noa, ka iti te ōwehenga o te tipu i waenga i ngā hua kuru, ā, he pai te pānga o te para o te hiku.
Kua tino pai ake te kounga kukū matotoru me te hua o te para para.
