He mea nui te mahi a te mira kōhatu Raymond i roto i te whakarite i te paura kōhatu kua whakakorengia te whanariki. Ka pā tika te kounga o te mira kōhatu Raymond ki te kounga, te pai me te tohatoha rahi o te matūriki o te paura kōhatu. Ka whakamāramahia i raro nei ngā āhuatanga hangarau me te whakamahinga motuhake o te mira huri kōhatu Raymond i roto i te whakakorenga whanariki, te pakaru kōhatu.
I. Te hiranga o te whakamahinga o te mira kōhatu Raymond i roto i te pakaru kōhatu kua whakakorengia te whanariki
I tēnei wā, neke atu i te 90% o ngā tipu hiko wera i Haina e whakamahi ana i te hangarau whakakorenga whanariki gypsum, he hangarau kua pakeke, he iti hoki te utu. Me paura whanariki ngā tukanga e rua hei mimiti i te hauhā whanariki, ā, ki te iti ake te rahi o te matūriki o te paura whanariki, ka pai ake te mimiti o te SO2.
II. Ngā āhuatanga matua e pā ana ki te whai huatanga o te tango pūhā o te kōhatu
（1）Te kounga o te kōhatu kōhatu
Ko te tikanga, me nui ake te nui o te CaSO4 i roto i te kōhatu i te 85%. Mēnā he iti rawa te nui, ka raru pea te mahi nā te nui o ngā poke. Ko te kounga o te kōhatu ka whakatauhia e te nui o te Cao. Ko te teitei ake o te parakore o te kōhatu, ko te pai ake o te whai huatanga o te tango whanariki. Engari ehara i te mea ko te kōhatu he nui te CaO, engari ko te teitei ake, ko te pai ake. Hei tauira, ko te kōhatu he nui ake te Cao i te 54% he Dali Petrochemical nā te mea he teitei te parakore, kāore e ngāwari ki te huri, ā, he kaha te pumau o te matū, nō reira kāore e pai hei whakamahi hei tango whanariki.
（2）Te rahi o te matūriki kōhatu raima (te pai)
Ka pā tika te rahi o te matūriki o te kōhatu ki te tere o te tauhohenga. Ina nui ake te horahanga o te mata, ka tere ake te tere o te tauhohenga, ā, he rawaka ake. Nō reira, ko te tikanga me eke te tere o te whitinga o te paura kōhatu i roto i te tatari 250 mesh, i te tatari 325 mesh rānei ki te 90%.
（3）Te pānga o te tauhohenga o te kōhatu karāhe ki te mahi a te pūnaha whakakorenga whanariki
Ka taea e te kōhatu uku he nui ake te kaha ki te tango i te hauhā whanariki i raro i te tikanga kia mau tonu te tere whakamahinga o te kōhatu uku. He nui te kaha tauhohenga o te kōhatu uku, he nui te tere whakamahinga o te kōhatu uku, ā, he iti te nui o te CaCO i roto i te gypsum, arā, he tino parakore te gypsum.
III. Te kaupapa mahi o te mira Raymond kōhatu
Ko te mira kōhatu Raymond he mea hanga mai i te mira whakahaere huri, te tātari whakarōpū, te kohikohinga hua me ētahi atu wāhanga. Ka whakamahia e te miihini matua te hanganga turanga whakarewa whakauru, ā, ka taea te whakamahi i te turanga whakamātao. Ka whakamahia e te pūnaha whakarōpū te hanganga whakarōpū tāpine whakahau, ā, ka whakamahia e te pūnaha kohikohi te kohikohinga pātere.
（1）Te kaupapa mahi o te mira kōhatu Raymond
Ka kuruhia ngā rauemi kia rite te rahi o te matūriki mā te mīhini kuru kauae, ka hikihia ki te pūwero rokiroki mā te ararewa paru, kātahi ka tukuna ki te kōhao matua mā te whāngai hei huri. Ka tautokona te kōhao matua o te mīhini ki runga i te anga pua paramu, ā, ka huri te taputapu roera huri i te tuaka pokapū. Ka neke whakapae te roera huri ki waho i raro i te mahi a te kaha porotītaha, kia pēhia ai e te roera huri te mowhiti huri, ā, ka huri te roera huri i te rakau roera huri i te wā kotahi. Ka makahia te rauemi e hikihia ana e te mata hurihuri ki waenganui i te roera huri me te mowhiti huri kia tutuki ai te mahi kuru me te huri nā te huri roera o te roera huri.
（2）Te tukanga mahi a te mira kōhatu me te wehewehe o Raymond
Ka pupuhihia te paura whenua e te hau o te pupuhi ki te whakarōpū i runga ake i te mīhini matua hei tirotiro, ā, ka taka tonu te paura pai me te paura matotoru ki roto i te mīhini matua hei huri anō. Mēnā ka tutuki te pai o te paura i te whakaritenga, ka rere ki roto i te kaikohi hau me te hau, ā, ka tukuna mā te paipa putanga paura i muri i te kohikohinga, koinei te hua kua oti (ka taea e te rahi o te matūriki o te hua kua oti te eke ki te 0.008mm). Ka rere te hau parakore ki roto i te pupuhi mā te paipa i te pito o runga o te hau, ā, ka rere te ara hau. Haunga te pēhanga pai mai i te pupuhi ki te rūma huri, ka rere te hau i roto i ētahi atu paipa i raro i te pēhanga kino, ā, he pai ngā āhuatanga akuaku o roto.
IV. Ngā āhuatanga hangarau o te mira kōhatu Raymond
Ko te mira Raymond Limestone i hangaia e HCMilling (Guilin Hongcheng) he whakahoutanga hangarau i runga i te mira huri momo-R. Kua tino pai ake ngā tohu hangarau o te hua ki te whakataurite ki te mīhini momo-R. He momo mira huri hou tēnei, he tino pai te mahi me te penapena pūngao. Ko te matotoru o ngā hua kua oti ka taea te 22-180 μM (80-600 mata).
(1) (Hangarau Hou) he anga puāwai paramu me te taputapu huri porotaka poutū, he hanganga matatau, he whaitake hoki. He tino iti te wiri o te mīhini, he iti te haruru, he pumau te mahi, ā, he pono te mahi.
（2）He nui ake te kaha tukatuka o ngā rauemi i te wā huri kotahi, ā, he teitei ake te whai huatanga. Neke atu i te 40% te pikinga o te putanga i ia tau, ā, neke atu i te 30% te penapena i te utu whakamahi hiko kotahi.
（3）Kei te putanga hau toenga o te mīhini patu puehu he taputapu kohikohi puehu, ā, e eke ana te pai o tana kohikohi puehu ki te 99.9%.
(4) He hoahoa hanganga hiri hou tōna, ā, ka taea e te taputapu huri roera te whakakī i te hinu i roto i ngā haora 300-500.
（5）E whakamahi ana i te hangarau rauemi koranu chromium teitei ātete-kakahu ahurei, he pai ake mō ngā āhuatanga tukinga me te hurihuri me te auau teitei me te kawenga nui, ā, ko tōna roa mahi he tata ki te toru ngā wā i tērā o te paerewa ahumahi.
Ki te whakataurite ki te mira Raymond tuku iho, te mira roera whakatārewatanga, te mira pōro me ētahi atu tukanga, ka taea e te mira Raymond kōhatu te whakaiti i te whakapaunga pūngao mā te 20% ~ 30%, ā, ka taea te whakapai ake i te whakaritenga o te paura kōhatu desulfurization hoa taiao.
