Mira poutūHe momo taputapu huri e whakamahia ana hei tukatuka i ngā rauemi papatipu hei paura pai, he mea whakamahi whānuitia i roto i te maina, te matū, te whakarewa, te hanga me ētahi atu ahumahi. I roto i tēnei tuhinga ka whakamāramahia e mātou ngā āhuatanga o te mira huri poutū.

Mīra Roera Poutū HLM

Rahi whāngai mōrahi: 50mm

Te kaha: 5-700t/h

Te matotoru: 200-325 mata (75-44μm)

Ngā rauemi e tika ana: ko ngā kohuke kore-whakarewa pērā i te konupūmā kāponāte, te barite, te calcite, te gypsum, te dolomite, te potash feldspar, me ētahi atu, ka taea te huri pai me te tukatuka. He ngāwari te whakarerekē i te pai o te hua, ā, he māmā noa te whakahaere.

1. Teitei o te whai huatanga o te huri

Ka whakamahia e te mira poutū te mātāpono huri moenga rauemi hei huri i ngā rauemi, he iti ake te whakapaunga pūngao e hiahiatia ana. He 30% te iti iho o te whakapaunga hiko o te pūnaha huri i tērā o te pūnaha mira pōro, ā, i te pikinga ake o te makuku o te rauemi mata, ka nui ake te penapena hiko.

2. Te kaha whakamaroke teitei ake

Mīhini mira poutūKa whakamahia te tikanga tuku hau, ina he nui ake te makuku o ngā rauemi mata (pēnei i te waro, te para, me ētahi atu), ka taea te whakahaere i te pāmahana hau e tomo ana kia eke ai te hua ki te makuku e hiahiatia ana.

3. Te rere o te tukanga māmā

He wehewehe te mira poutū, ā, ko te hau wera o te putorino ka whakamahia hei kawe i ngā rauemi. Kāore e hiahiatia he whakarōpū, he hiki rānei. Ka taea e te hau kei roto te puehu mai i te mira te tomo tika ki te putea kohikohi paura hei kohi i te hua. He pai te tukanga māmā ki te whakaiti i te tere rahunga, me te whakanui ake i te tere mahi. Ko te whakatakotoranga kiato e hiahia ana kia 70% te horahanga hanga i tērā o te pūnaha mira pōro.

4. Rahi matūriki whāngai nui

Mō te mira poutū, ka taea e te rahi o te matūriki whāngai te eke ki te 5% (40-100mm) o te whānui o te rōra mira, nō reira ka taea e te pūnaha mira poutū te whakaora i te kuru tuarua.

5. He teitei te taumata o te whakakotahitanga o ngā hua

Ka taea te wehewehe i ngā hua whai tohu i roto i te mira poutū i te wā tika, kia kore ai e huri nui rawa, ā, kia ōrite te rahi o te hua; ā, he ngāwari te kuru i ngā hua i roto i te mira pōro nā te tikanga mahi. Hei tāpiri, ka taea e te pūnaha huri poutū te whakarite i te pai o te hua i te wā tika me te watea mā te whakarite i te tere wehewehe, te tere hau me te pēhanga o te roera huri.

6. He iti te haruru, he iti rawa te puehu

Kāore te roera huri me te kōpae huri e pā tika ana i roto i te mira poutū, ā, he 20-25 tekipere te iti iho o te haruru i tērā o te mira pōro. Hei tāpiri, he hiri whakauru kei te mira poutū, ka whakahaerehia te pūnaha i raro i te pēhanga kino hei whakaiti i te puehu me te haruru.

Ka taea e te mira poutū te tukatuka i te paura pai ake i te mira pōro, ā, he nui ake te tere whakaputa, ki te hiahia koe ki te mōhio ki tengā utu mira poutū, tēnā whakapā mai ki a mātou mō ētahi atu kōrero.
