Kua rerekē te hangarau huri i ngā tau, ā, kua piki haere te rongonui o ngā mira poutū. Kua whakamātauhia ka taea te whakapai ake i te pai o te huri mā te huri i waenga i ngā matūriki mā te whakamahi i te tukanga huri maroke. I raro i ngā āhuatanga motuhake, ki te whakaritea ki te tukanga huri mākū mira ngongo tuku iho, ka taea te whakapai ake i te tere whakaora hua me te kounga hua. Hei kaihanga o te mira poutū HLM,Mīhini HCMka whakamōhio atu mātou ki a koe i te hangarau huri poutū i tēnei rā.

Neke atu i te 100 tau, ko ngā momo mira ngongo te taputapu huri e whakamahia whānuitia ana i roto i te tukatuka kohuke. Heoi, kua puta ngā huringa i roto i ētahi rāngai ahumahi, pērā i te umanga sima, kei reira ngā mira poutū e whakamahia ana mō te whakamaroke me te huri. Nā te whakaiti i te whakapaunga pūngao me te pikinga o te kaha whakamaroke o tēnei momo mira tēnei. He iti ake te pēhanga e whakamahia ana e ngā mahi mira poutū i ngā mira pēhanga teitei. He mea nui te kaha o te rauemi ki te whakakoi, ā, me whakaaro pea ki te whakamahinga o ngā whakarewa ātete-kakahu. He tino pumau hoki te taputapu huri.

I roto i te whakapūmau me ngā tukanga e pā ana, ka kapi te pai o te whāngai poutū i te whānuitanga whānui, mā te whakamahi i ngā kōpae huri papatahi me ngā roera huri whakarara. Ka puta te huri o ngā rauemi i roto i te āputa i waenganui i te kōpae huri hurihuri me te roera huri. Ka tomo te whāngai mira ki waenganui o te kōpae huri ka neke ki te taha o te kōpae huri me te āwhina o te kaha porowhita me te waku. Mā tēnei ara, ka ngaua e ngā roera huri kōniko e rua, e toru, e whā, e ono rānei e mau ana ki te taha o waho o te kōpae huri.Te roera huri kua honoa ki te rango waipēhi hei whakarato i te pēhanga huri mō te huri i ngā rauemi. Ko te piko o te roera huri whakarara ka whakaputa i te kaha kutikuti, e whakarite ana i te huri me te kawe i te rauemi i raro i te roera huri. Ko te hoahoa pari e pupuri ana i ngā kaha kutikuti ki te iti rawa hei ārai i te kakahu nui o ngā roera huri. Ko te arai kōpae huri me ngā roera huri he mea hanga ki ngā whakarewa konupora-teitei ātete-kakahu. Ka wehe ngā matūriki whenua i te kōpae huri ka haria e te hau ki roto i te wehewehe paura hihiri me te whai hua, e whakauruhia ana ki te mira. Ka wehe ngā matūriki hua i te mira me te rere o te hau, ā, ka whakahokia ngā matūriki kua whakahokia ki te kōpae huri me te whāngai hou mō te huri tonu. Ko te pēhanga e hiahiatia ana mō te huri ka whakaratohia e te pūnaha e kiia nei ko te "pūrere puna waipēhi".

Ko te pēhanga huri o te 50~100bar i te taha pēhanga teitei o te rango waipēhi e ārahi ana i te kaha huri ki te rauemi kei roto i te āputa i waenganui i te roera huri me te kōpae huri. Ko te pēhanga i te taha pēhanga iti o te rango waipēhi he tata ki te 10% o te taha pēhanga teitei, e āhei ai te roera huri ki te whai i tētahi nekehanga ngāwari. Ka whakatikatikaina ngā āhuatanga whakaputa o te rauemi mā te whakatakoto i te pēhanga i ngā taha e rua, kia pakari ake ai, kia ngāwari ake ai te nekehanga o te roera huri. Ka honoa ngā tukanga e rua ki te mahara i runga i te rango waipēhi, e āhei ai te nekehanga maeneene ake o ngā roera huri. Mā tēnei whirihoranga ka taea ngā mahi huri me ngā taumata wiri tino iti. E rua ngā taputapu waipēhi motuhake o ia takirua roera huri o te mira roera poutū, ka taea te whakamahi i ngā pēhanga rerekē ki ia takirua roera huri, he tino painga ki ngā rauemi he ngoikore te mahi ngau. Ka whāngaihia te rauemi ki roto i te mira mā te takirere raka hau, ā, ka uru te hau e hiahiatia ana ki te mira mai i te wāhanga o raro o te mira. Ka haere te hau mā te mowhiti pūwero tata ki te taha o te pereti huri ka haria te rauemi ki runga ki roto i te whakarōpū. Ko te hau e rere ana i roto i te mira ka ārahihia e te pā hau pūnaha. Ka puta ngā rauemi whenua i te mira i muri i te haerenga mā roto i te whare herehere hurihuri o te wehewehe paura tino pai, e honoa ana ki te mira. Ka kohia te hua e te kaikohi puehu i muri i te mira, ka tukuna ki te whare putunga rokiroki mō ngā tukanga e whai ake nei.

I roto i te Taiwhanga Paura Mīhini HCM, he maha ngā momo konganuku e tukatukahia ana i runga i ngā mira poutū HLM. E whakaatu ana ngā hua, ina whakamahia ngā mira poutū mō te whakamaroke me te huri, i ētahi wā ka taea te whakamahi i ngā hua matotoru ake i roto i te tukanga whakapūmau me te whakatutuki tonu i te kounga rite ki ngā whāngai pai ake o ngā mira tuku iho. Ko te hua. Ki te whakatauritea ki ngā taputapu huri tuku iho, he maha ngā painga o ngā mira roera poutū.

I roto i te poto, he nui ake te rahi o te matūriki whāngai i tō te mira pōro, nō reira ka taea te whakakore i te tukanga kuru tuatoru-wāhanga. He painga te whakamahi i te whakamaroke me te huri i ngā wāhi he iti te makuku o te rauemi. Hei tāpiri, kāore te mata hou o te konganuku e pāngia e te wai kua mau i te taha. Ka taea te whakahaere motuhake i ngā taputapu whakamaroke me te huri mai i te tukanga o mua me te tukanga e whai ake nei, kia taea ai te whakapai ake i te mahi a ngā taputapu me te kore e pā ki ētahi atu āhuatanga whakahaere. Ka rongoatia te hua whenua ki roto i te whare putunga, ka taea te mahi hei parepare ina kati te tukanga whakarite rauemi mata.

 In addition, the mud density in the flotation equipment can be controlled. In the future, vertical mill grinding technology will be more widely used.Welcome to contact us:hcmkt@hcmilling.com
