[Kudziwa zambiri] Kodi chosungiramo zinthu chimazindikira bwanji ntchito yoyeretsa ndi kuchepetsa kuipitsidwa ndi kusankha?

Mu njira yolekanitsa maginito ya magnetite, chifukwa cha maginito agglomeration, n'zosavuta kupanga "maginito inclusions" ndi "non-magnetic inclusions", zomwe zimakhudza kwambiri kuchuluka kwa ma concentrates. Makina ochapira ndi kuyika maginito okhazikika okha omwe adapangidwa ndi Walt ndi mbadwo watsopano wa zida zofooka za maginito magnetic field. Amaganizira bwino magawo amphamvu monga mphamvu ya maginito, mphamvu yokoka, kuyenda, mphamvu ya centrifugal, ndi zina zotero. Pophatikizidwa, magawo ogwirira ntchito amasinthidwa okha malinga ndi mawonekedwe a miyala, zomwe zimatha kuchepetsa bwino kuchuluka kwa zonyansa monga silicon, phosphorous, ndi sulfure mu maginito ores, ndikupeza maginito apamwamba komanso zinthu zapakati monga ma concentrates mu njira yolekanitsa maginito, zomwe zimayesedwa pasadakhale. Kuyika komaliza ndikoyenera kugwiritsa ntchito bwino maginito concentrator, zomwe zimatsegula njira yatsopano kuti iron concentrate ya dziko langa igwiritse ntchito njira "yokonza ndi kuchepetsa zonyansa".

Mfundo yogwirira ntchito

Mcherewu umalowetsedwa pakati ndi pamwamba pa makina oyeretsera ndi chotenthetsera cha mkuwa ndi chitoliro chodyetsera mkuwa, ndipo umatsukidwa ndi madzi otsukira. Pakati pa ma coil awiriwa ndi pamene coil imachotsedwa, popeza mphamvu ya maginito yotsika imachepa kwambiri, imadulidwa ndikufalikira ndi madzi oyenda mofulumira kwambiri, kotero kuti gangue imodzi, matope a mkuwa ndi zamoyo zolumikizana zimasakanikirana, makamaka zamoyo zosauka zolumikizana. Lamba wothamanga uli mmwamba, ndipo pansi pa mphamvu ya madzi oyenda mwamphamvu ozungulira mmwamba, umakwera mpaka m'mphepete mwa madzi odzaza ndipo umatulutsidwa kukhala tailings makamaka opangidwa ndi matupi olumikizana.

Mfundo yogwirira ntchito ya makina osankha ma electromagnetic panning

Miyala ya maginito yomwe ili mu miyalayi imapangidwa ndi maginito chifukwa cha mphamvu ya maginito yopangidwa ndi coil yamagetsi, ndipo tinthu ta maginito ta maginito tomwe timapangidwa ndi maginito timasanduka maginito a dipole, ndipo maginito ambiri amakopana kuti apange maunyolo a maginito. Pamene coil yazimitsidwa, kulumikizana kwa mphamvu nthawi yomweyo kumafalikira kwathunthu chifukwa cha kudulidwa kwa axial pansi pa kayendedwe ka madzi othamanga kwambiri komanso kukwera. Njira yomwe ili pamwambapa imabwerezedwa pamene coil yotsatira yapatsidwa mphamvu ndikuchotsedwa mphamvu. Njirayi imachitika kangapo, kuti zinthu zamaginito zitha kusankhidwa kangapo mu makina oyeretsera kuti zipeze mphamvu ya magnetite yapamwamba, ndipo nthawi yomweyo, kuchuluka kwa zinthu zodetsedwa monga SiO2 kumachepetsedwanso.

Njira yowongolera makina ochapira

Makina owunikira amagwiritsa ntchito njira ziwiri zowongolera mphamvu zamagetsi, zomwe zikutanthauza kuti kuchuluka kwa madzi ochulukirapo ndi kuchuluka kwa madzi ochulukirapo ndiye zolinga zowongolera. Kuchuluka kwa madzi ochulukirapo kumayendetsedwa ndi kukula kwa mphamvu ya maginito, ndipo kuchuluka kwa madzi ochulukirapo kumayendetsedwa ndi kutseguka kwa valavu yapansi. Mu dongosolo lowongolera, poika miyezo ya kuchuluka kwa madzi ochulukirapo ndi kuchuluka kwa madzi ochulukirapo, dongosolo lowongolera limagwiritsa ntchito njira yanzeru yowongolera mphamvu ya maginito ndi kutseguka kwa valavu yapansi kuti isunge mtengo wa chinthucho mkati mwa gawo linalake logwirira ntchito.

Ngati kuchuluka kwa chakudya cha mkuwa sikukhazikika, makina owongolera amasinthira okha valavu yapansi malinga ndi kusintha kwa kuchuluka kwa madzi mkati mwa makina oyeretsera, kuti maginito mkati mwa makina oyeretsera asasinthe ndikusunga malo okhazikika okonzera; Pamene madzi sakhazikika, makina owongolera amasinthira mphamvu ya maginito malinga ndi kusintha kwa kuchuluka kwa madzi oyeretsera kuti atsimikizire kukhazikika kwa index ya concentrate.

Makina ogwiritsira ntchito magetsi odzipangira okha amagwiritsa ntchito njira yapamwamba yowongolera makina ochapira pogwiritsa ntchito PID, yomwe siifunikira ntchito yamanja ndipo nthawi zonse imagwira ntchito bwino. Pogwiritsa ntchito ukadaulo wa intaneti ya Zinthu, magawo ogwirira ntchito amatumizidwa ku nsanja yakutali yamtambo, ndipo mafayilo amagetsi amakhazikitsidwa kuti zida zizitha kuyang'anira moyo wonse; Akatswiri a kampani yathu yokonza mchere amatha kusintha magawo okonza mchere a makina ochapira pogwiritsa ntchito nsanja yowonera yakutali kuti athandize ogwiritsa ntchito bwino.
