Pakadali pano, chifukwa cha kukula kwa mafakitale padziko lonse lapansi, kuchuluka kwa kugwiritsa ntchito zinthu zosiyanasiyana za mchere kukupitirira kukula, kaya ndi zitsulo kapena zopanda zitsulo, kugwiritsa ntchito zinthu kukuwonjezeka kwambiri. Zotsatira zake, kusonkhanitsa, kupanga zinthu zambiri, komanso mwanzeru kwa zida zosonkhanitsira zinthu kwakhala cholinga chatsopano cha makampani opanga migodi. Kuphatikiza apo, kugawa kwa zinthu zamchere padziko lonse lapansi sikufanana kwambiri. Malo ambiri osungiramo zinthu zamchere amapezeka m'maiko ochepa. Mwachitsanzo, malo osungiramo zinthu zachitsulo ku Australia, Brazil, ndi Russia ndi 54% ya malo osungiramo zinthu zachitsulo padziko lonse lapansi; mkuwa ku Chile, Australia, ndi Peru Chiwerengero cha malo osungiramo zinthu zamchere ndi 53% ya malo osungiramo zinthu zachitsulo padziko lonse lapansi; chiwerengero cha malo osungiramo zinthu za bauxite ku Guinea, Australia, ndi Brazil ndi 58% ya malo osungiramo zinthu za bauxite padziko lonse lapansi. Ngakhale kuti mchere m'madera amenewa ndi wolemera kwambiri, chifukwa cha kuchuluka kwa migodi ndi kukula kwake, kuchuluka kwa zinthu ndi migodi kwatsika. Chiwerengero chachikulu cha malo osungiramo zinthu ndi miyala yamitundu yosiyanasiyana chabweretsa kuipitsidwa kwatsopano kwa chilengedwe komanso zoopsa zomwe zingachitike. Kugwiritsa ntchito mwapamwamba Zipangizo, kukonza njira zogwirira ntchito m'migodi ndi zokongoletsa, kuchepetsa kusungidwa kwa zinyalala ndi kuipitsa chilengedwe, komanso kuwonjezera kugwiritsa ntchito mchere kwakhala chisankho choyamba pakukula kwa migodi.
M'mayiko omwe ali ndi mchere wambiri wachitsulo, zinthu zomwe zili m'matanthwe a miyala zimachokera makamaka ku zinyalala zomwe zili ndi maginito ochepa komanso zomwe sizili ndi maginito. Njira yabwino kwambiri yochepetsera zinthu zomwe zili m'matanthwe a miyala ndikugwiritsa ntchito zipangizo zamakono kuti ziwonjezere mphamvu ya maginito ndi zinthu zina zamtengo wapatali. Zipangizozo zimasankhidwa kuti ziwongolere kuchuluka kwa momwe mchere umagwiritsidwira ntchito.
Cholekanitsa maginito chozizira ndi mafuta chopangidwa ndi Shandong Huate Magnetoelectricity chili ndi mphamvu yayikulu, mphamvu yayikulu yogwiritsira ntchito, kusintha kwanzeru, komanso kudzizindikira zolakwika pakulekanitsa zinthu zofooka zamaginito komanso kubwezeretsa kwathunthu kwa tailings. Chogulitsa chachikulu chomwe chili mu chipangizochi chimagwira ntchito bwino popanda kuyang'aniridwa komanso kulamulira kutali, ndipo chingagwiritsidwe ntchito kwambiri pakulekanitsa mchere wofooka monga hematite, limonite, manganese ore, ilmenite, ndi quartz, feldspar, sauria Kuchotsa chitsulo ndi kuyeretsa mchere wosakhala wachitsulo monga quarry. Pakadali pano, chatumizidwa m'magulu ku Australia, Austria, Brazil, South Africa, Malaysia, Philippines, India ndi madera ena adziko lapansi.
Mphete yanzeru yozungulira yoziziritsidwa ndi mafuta yopangidwa motsatira miyezo ya ku Australia yatuluka bwino pamzerewu
Huate Magnetoelectric Intelligent Oil-cooled Vertical Ring High Gradient Magnetic Separator ili ndi makhalidwe awa:
1
Dongosolo lozizira lodziwika bwino padziko lonse lapansi loyenda ndi mafuta ndi madzi
Posintha mphamvu zamagetsi kukhala mphamvu yamaginito, ma coil a vertical ring high gradient magnetic separator adzatulutsa mphamvu zambiri zotentha. Pakadali pano, njira yozizira ya coil yachizolowezi ya high gradient magnetic separator ndi kuziziritsa madzi mkati. Chifukwa cha mphamvu ya madzi, panthawi yogwiritsa ntchito zida, Madzi omwe ali mu waya woyatsira ndi osavuta kupanga sikelo chifukwa cha kutentha komwe kumawonjezeka, komwe kumayambitsa kutsekeka, komwe kumakhudza mphamvu yotaya kutentha. Amafunika kutsukidwa nthawi zonse. Kulephera kwake kumakhala kwakukulu ndipo nthawi yotaya kutentha ndi yochepa. Dongosolo loziziritsa kutentha la mafuta ndi madzi ozizira lomwe limapangidwa ndi Huate Magneto limagwiritsa ntchito ma coil oviikidwa mu mafuta ndi kuyenda kwakukulu kwa kutentha kwa mafuta ndi madzi ozungulira. Kugwiritsa ntchito madzi osambira kumachotsa kutentha kwa coil, komwe kungathandize kwambiri kutentha kwa coil ya magnetic separator. Vuto la kutaya kutentha kwa coil ya magnetic separator yamphamvu kwambiri limatsegula njira yatsopano yothetsera kulekanitsa miyala yachitsulo yotsika, yopyapyala, komanso yofooka komanso kuyeretsa miyala yosakhala yachitsulo.

Dongosolo lowongolera lodziyimira lotsogola lowongolera madzi
Mlingo wa madzi mu chipinda chokonzera ndi chimodzi mwazinthu zofunika kwambiri zomwe zimakhudza chizindikiro chokonzera. Mzere wowongoka wamba umagwiritsa ntchito kusintha kwa manja, komwe kumafuna ntchito yambiri ndipo kumakhala ndi zinthu zambiri za anthu, ndipo chizindikiro chokonzera sichikhazikika bwino. Dongosolo lanzeru lowongolera madzi lopangidwa ndi Huate, kudzera mu chipangizo cholumikizirana ndi madzi, chipangizo chowunikira chidziwitso cha sensa yamadzi, ndi dongosolo lotulutsa mafuta oyendetsedwa ndi gasi, limazindikira momwe madzi akusinthira nthawi yeniyeni ndipo limatha kusinthidwa pa intaneti nthawi yeniyeni, nthawi zonse kusunga zigoli zabwino kwambiri Sankhani mlingo.

Makina oyeretsera madzi ndi zimbudzi zokha kuti atulutse madzi
Kuyera kwa njira yotulutsira madzi ndiye chinsinsi chotsimikizira kuti bokosi la media likuyenda bwino. Mphete yanzeru ya Huate imagwiritsa ntchito fyuluta yotsutsana ndi mkuntho, ndipo ili ndi chipangizo chothandizira kupanikizika ndi njira yotulutsira madzi a m'madzi a m'nyanja. Madzi a m'nyanja akafika pamlingo winawake, fyulutayo imatulutsa madzi a m'nyanja yokha, nthawi zonse imasunga madzi otuluka oyera, imaonetsetsa kuti dzenje lotulukira la chitoliro cha madzi otuluka silikutsekedwa, ndipo imazindikira bwino momwe bokosi la media limatulutsira madzi.

Kuzindikira kutentha bwino komanso njira yochenjeza msanga
Ili ndi njira yonse yochenjeza kutentha. Gawo la coil ndi malo olowera ndi kutuluka kwa madzi a chosinthira kutentha zili ndi zida zowunikira kutentha kuti zizindikire kutentha komwe kumagwira ntchito kwa chipangizocho nthawi yeniyeni ndikutumiza chidziwitsocho ku malo olamulira. Zipangizo zikalephera kuyeretsa kutentha kapena mavuto ena, kutentha kumafika pamlingo wapamwamba womwe watchulidwa. Njira yochenjeza yoyambirira idzapereka alamu ndikusiya kugwira ntchito kuti zitsimikizire kuti chipangizocho chikugwira ntchito bwino.

Chipangizo chotetezera cha alamu yotulutsa madzi
Momwe ntchito ya wodzizira wokhazikika wozungulira wozizira mafuta ndi yokwera kwambiri ndikuti kuthamanga kwa madzi ozizira kumakhala kokwera ndipo kuthamanga kwa mafuta ozizira kozungulira kumakhala kochepa. Pamene choziziritsira chapakati chituluka panthawi yogwiritsidwa ntchito kwa nthawi yayitali, chidziwitso chamadzimadzicho chikhoza kutumizidwa ku chipangizo chochenjeza msanga kuti chitsimikizire chitetezo cha nthawi yayitali cha choziziritsira ndi chosinthira kutentha.

Dongosolo lolamulira logawa la DCS lotsogola
Kugwiritsa ntchito ukadaulo wa intaneti ya zinthu kumatha kutumiza chidziwitso cha malo ndi magawo ogwiritsira ntchito a vertical ring high gradient magnetic separator ku chipinda chowongolera chakutali nthawi yeniyeni kudzera mu masensa, ndikupanga dongosolo lowongolera la DCS la zida zakutali, lomwe lingathe kuwonetsa magawo ogwiritsira ntchito zida nthawi yeniyeni. Chitani kusanthula deta, kuzindikira zolakwika ndi kukonza zida zomwe zimagwiritsidwa ntchito kuti zigwire ntchito mosasamala komanso mwanzeru mgodi wa zida.
Cholekanitsa maginito chozizira ndi mafuta chokhazikika chili ndi njira yowunikira yolekanitsa yolekanitsa ndi njira yowongolera yothandizira njira. Panthawi yolekanitsa zinthu, palinso njira zothandizira zowongolera kayendedwe ka slurry ndi njira yowunikira. Kuzindikira pa intaneti ndi mayankho azidziwitso, sinthani mphamvu yogwiritsira ntchito mphete yolunjika munthawi yake, onetsetsani kuti magawo otulutsa a pulp ndi olimba, ndikupereka chitsimikizo choyambira chokwaniritsa zizindikiro zokhazikika zokonzera.
Kugwiritsa ntchito kwa makina oyeretsera anzeru okhazikika omwe amapangidwa ndi mafuta okhazikika (high gradient magnetic separator) kukuwonetsa kuti ukadaulo ndi zida zoyeretsera mchere m'dziko langa zalowa patsogolo padziko lonse lapansi, makamaka pakulekanitsa zinthu zofooka zamaginito kuchokera ku migodi yachitsulo yapadziko lonse, kulekanitsanso migodi yachitsulo, komanso kuchotsa migodi yopanda chitsulo. Kuyeretsa chitsulo kwakhala ndi gawo lofunika kwambiri, kukonza kuchuluka kwa kubweza kwa mchere ndi khalidwe la zinthu, kuchepetsa kuyika ming'alu ndi kuipitsa chilengedwe, kupititsa patsogolo moyo wa migodi, kulimbikitsa kupita patsogolo kwaukadaulo m'makampani, komanso kugwiritsa ntchito bwino zinthu zamchere padziko lonse lapansi. Kuteteza chilengedwe kumagwira ntchito yothandiza pakukweza, komanso kudzabweretsanso phindu lalikulu pazachuma komanso chikhalidwe cha anthu pakukula kwa migodi yanzeru.
