Ko te "Mīhini Whakaranu Whakakotahi Whakarewa" tētahi o ngā taputapu matua o te tukanga whakaputa whakakotahi. He mea whakamahi motuhake mō te whakaranu me te whakapūkara i ngā rauemi pēnei i te paura rino, te mea here (pēnei i te bentonite), te rere (pēnei i te paura kōhatu) me te konganuku whakahoki, he kaha teitei, he tino pai, he tino ōrite hoki.
He Kupu Whakataki ki te Whakaranu Whakakorikori Pelletizing CO-NELE
Te whakaranu ōrite: Me whakarite kia tino ōrite te horapa o ngā rauemi mata (ina koa ko ngā mea here iti) ki runga i te mata me roto o ngā matūriki paura konganuku, koinei te pūtake mō te kounga o te whakapūkara me te whakapūkara i muri mai (kaha, ōritetanga o te hanganga, ngā āhuatanga whakarewa).
Te whakapūkara/te whakapūkara i mua i te whakapūkara: I te wā o te tukanga whakaranu kaha, ka tukituki, ka piri, ka whakakotahi ngā matūriki angiangi (te paura rino, te mea here, me ētahi atu) i raro i te kaha miihini me te taumahatanga mata wai (me tāpiri he nui o te wai e tika ana) hei hanga pōro whaea iti (ngā "pōro-āhua" me ngā "pōro-iti" rānei) me te kaha motuhake. Ka tino whakapai ake tēnei i te pai o te whakapūkara me te kounga o te mīhini hanga pōro kōpae, pōro rango rānei e whai ake nei.
Te kaupapa mahi o te pelletizingRanu Whakaranu Kaha:
Ko ngā wāhanga matua o te mīhini whakaranu kaha he huri tere-teitei (he taputapu whakaranu he āhua motuhake) me te tāke whakaranu hurihuri (he oko).
Ka pāngia te rauemi e te huri tere-rahi i roto i te tāke whakaranu e te pānga kaha, te kutikuti, te kawe me te horapa. Ka whiua e te taputapu huri te rauemi ki te pakitara o te oko, ā, ka ārahihia e te hanganga pakitara o te oko (pēnei i te waru pūmau, te hoahoa pereti arai) te rauemi ki te rohe mahi huri, ka hangaia he tohanga rauemi kaha me te nekehanga matū.
Ko tēnei whakaurunga pūngao miihini kaha-teitei te mea matua hei wehewehe i a ia mai i ngā mīhini whakaranu noa, i ngā mīhini whakaranu tuku iho rānei. Ka taea e ia te wawahi i te whakakotahitanga i waenga i ngā matūriki rauemi mata, te wikitoria i te hononga o te rauemi, me te akiaki i ngā matūriki rauemi ki te whakaputa i te nekehanga whanaunga kaha, kia tutuki ai te whakaranu tino ōrite i runga i te tauine moroiti, me te whakatairanga i te whakakotahitanga o ngā matūriki angiangi ki roto i ngā pōro whaea.
Ngā painga o te mīhini whakaranu pelletizing kaha:
Te kaha o te whakaranu: te tere raina o te rotor (tae atu ki te 20-40-m/s) me te matotoru o te whakauru pūngao.
Te ōritetanga o te ranunga: Ka taea te whakatutuki i te ōritetanga o te ranunga moroiti e uaua ana ki te whakatutuki me ngā taputapu tuku iho i roto i te wā poto rawa (te nuinga o te tekau hēkona ki te meneti), inā koa mō te marara o ngā wāhanga iti.
Te whakapūtanga matūriki tino whai hua: Ka taea e ia te whakaoti i ngā mahi matua e rua o te whakaranu me te whakapūtanga i mua i te pōro i te wā kotahi. He rite te rahi o ngā matūriki o ngā pōro whaea kua hangaia (i te nuinga o te wā kei roto i te awhe o te 0.2-2mm), he hanganga matotoru, he kaha pai hoki, e whakarato ana i ngā rauemi mata kounga teitei mō te whakapūtanga i muri mai.
Kaha te urutau: Ka taea e ia te whakahaere i ngā rauemi o ngā rahi matūriki rerekē, ngā makuku rerekē me ngā matotoru rerekē, ā, he tino kaha te manawanui ki ngā huringa o ngā rauemi mata.
Te pai o te whakaputa: he poto te wā whakaranu/whakaranu me te kaha tukatuka nui a te mīhini kotahi.
Penapena Pūngao: Ahakoa he nui te mana whakauru kotahi, nā te poto o te wā whakaranu me te pānga pai, tera pea ka iti iho te whakapaunga pūngao mō ia wae putanga i tērā o ngā tukanga tuku iho.
Whakapai ake i ngā tukanga e whai ake nei: Whakaratohia he rauemi mata pumau ake mō ngā tukanga porotaka me te tunu, whakapai ake i te tere porotaka, te kaha o te pire, te ōritetanga me te putanga, me te whakaiti i te kai here.
Hanganga kiato: He iti noa te wāhi e nohoia ana e ia.
He pai te ātete hau: He ngāwari te mahi kati, te whakaiti i te mawhiti o te puehu, me te whakapai ake i te taiao mahi.
Tūranga i roto i te tukanga whakaputa pellet:
Kei muri i te pūnaha puranga me mua i te kaiwhakaranu pellet (kōpae, rango rānei).
Tukanga taketake: ipu puranga → whāngai tauanga → whakaranu kaha (whakaranu + whakaporo-mua) → whakaporo (hurihuri i te pōro whaea hei pōro matomato whai mana) → tātari → tunu → whakamatao → ngā poro kua oti.
Ko te mīhini whakaranu kaha mō te whakarewa i ngā pellet te taputapu matua paerewa o ngā raina whakaputa pellet hou, whai hua, me te tauine nui. Ka tutuki i a ia te whakaranu tino ōrite me te whakakoi pai o ngā rauemi i roto i te wā poto rawa mā te whakamahi i te kaha miihini kaha-teitei, ka whakatakoto i te turanga pakari mō ngā tukanga whakakoi me te tunu pellet i muri mai, ā, he mahi nui tana ki te whakapai ake i te putanga me te kounga o ngā pellet me te whakaiti i ngā utu whakaputa (ina koa ko te kai here). Ko tana mahi ka pā tika ki ngā tohu hangarau me te ōhanga o te raina whakaputa pellet katoa.
