I roto i te tukanga wehenga aukume o te magnetite, nā te whakakotahitanga aukume, he ngāwari te whakaputa i ngā "whakaurunga aukume" me ngā "whakaurunga kore-aukume", e tino pā kino ana ki te taumata o ngā kukū. Ko te mīhini horoi me te kukū aukume aunoa i whakawhanakehia motuhaketia e Walt he whakatupuranga hou o ngā taputapu wehenga aukume ngoikore. Ka whakaarohia whānuitia e ia ngā mara kaha whānui pēnei i te kaha aukume, te taumaha, te pūmau, te kaha poipoi, me ētahi atu. Mā te whakakotahi, ka whakatikatikaina aunoatia ngā tawhā whakahaere kia rite ki ngā āhuatanga o te konganuku, ka taea te whakaiti i te ihirangi o ngā poke pēnei i te silicon, te phosphorus, me te whanariki i roto i ngā konganuku aukume, me te whiwhi i ngā kukū magnetite kounga teitei me ngā hua takawaenga pēnei i ngā kukū i roto i te tukanga wehenga aukume, kua tohua i mua. He pai te kukū whakamutunga mō te mahi whakapai ake o te kukū magnetite, e whakatuwhera ana i tētahi huarahi hou mō te kukū rino o tōku whenua ki te whakatinana i te rautaki o te "whakapai ake me te whakaiti i ngā poke".
Te kaupapa mahi
Ka whāngaihia te konganuku ki waenganui me te taha o runga o te mīhini whakawātea e te pūwero whāngai konganuku me te paipa whāngai konganuku, ā, ka horoia atu e te wai horoi. I waenganui i ngā koiri e rua, ā, ina whakawetohia te koiri, nā te mea kua ngoikore rawa te kaha aukume ki raro, ka kutikutia, ka mararahia e te rere o te wai e hurihuri tere ana ki runga, kia uru ai te gangue kotahi, te paru konganuku me ngā rauropi hono ki roto, inā koa ko ngā rauropi hono rawakore. Kei runga ake te whitiki e rere ana, ā, i raro i te mahi a te rere wai e hurihuri kaha ana ki runga, ka piki ake ki te taha waipuke ka tukuna hei paru e titoa ana e ngā tinana piri.
Ko te kaupapa mahi o te mīhini whiriwhiri panning hikohiko
Ka aukumetia ngā kohuke aukume i roto i te konganuku e te papa aukume i hangaia e te koiri hiko, ā, ka huri ngā matūriki konganuku aukume hei poraka aukume, ā, he maha ngā poraka aukume e kukume ana tetahi ki tetahi hei hanga mekameka aukume. Ina whakawetohia te koiri, ka marara katoatia te hononga rere tere o te whakaweto mā te kutikuti axial i raro i te mahi a te hurihuri tere me te rere o te wai e piki haere ana. Ka whakahokia te tukanga o runga ake nei ina whakakahangia te koiri e whai ake nei, ā, ina tangohia te kaha. Ka mahia tēnei tukanga mō ngā wā maha, kia taea ai te tīpako i te rauemi aukume i roto i te mīhini whakakore i ngā wā maha ki te whiwhi i te kukū aukume kounga teitei, ā, i te wā kotahi, ka whakaitihia hoki te ihirangi o ngā poke pēnei i te SiO2.
Te tukanga whakahaere o te mīhini horoi
Ka whakamahia e te mīhini whakakorenga te mana whakahaere rua-whakaoho, arā, ko te kukū waipuke me te kukū rere raro ngā whāinga whakahaere. Ka whakahaerehia te kukū waipuke e te nui o te kaha o te papa aukume, ā, ka whakahaerehia te kukū rere raro e te whakatuwheratanga o te takirere raro. I roto i te pūnaha whakahaere, mā te whakatakoto i ngā uara whāinga o te kukū waipuke me te kukū rere raro, ka whakamahia e te pūnaha whakahaere he pūnaha whakahaere atamai hei whakahaere i te kaha o te papa aukume me te whakatuwheratanga o te takirere raro kia mau tonu te uara whāinga i roto i tētahi whānuitanga mahi.
Ina kore e pumau te nui o te whāngai o te konganuku, ka whakarite aunoa te pūnaha whakahaere i te takirere raro kia rite ki te huringa o te kukū rere o raro i roto i te mīhini whakakore wai, kia noho tonu ai te reo aukume i roto i te mīhini whakakore wai, kia mau tonu ai te taiao whakarōpū pumau; Ina kore e pumau te puna wai, ka whakarite te pūnaha whakahaere i te kaha o te papa aukume kia rite ki te huringa o te kukū waipuke o te mīhini horoi hei whakarite i te pumau o te taupū kukū.
Ka whakamahia e te mīhini whakakoi me te whiriwhiri hikohiko aunoa te tikanga whakahaere arotautanga PID-aunoa matatau, kāore e hiahiatia he mahi ā-ringa, ā, ka mahi tonu i te āhua pai rawa atu. Mā te whakamahi i te hangarau Ipurangi o ngā Mea, ka tukuna ngā tawhā whakahaere ki te tūāpapa kapua mamao, ā, ka whakatūhia ngā kōnae hiko mō ngā taputapu hei whakahaere i te huringa ora katoa; Ka taea e ngā tohunga tukatuka kohuke a tā mātou kamupene te whakarerekē mamao i ngā tawhā tukatuka kohuke o te mīhini horoi mā te tūāpapa aroturuki mamao kia pai ake ai te mahi ki ngā kaiwhakamahi.
