Kune ma reagents emvura, akaderera kusvika pakati nepakati ekusimba, ma electromagnetic flow metres anoshandiswa zvakanyanya. Anoyera kuyerera kwemvura mumitsara inobata zvinopisa uye zvine matope uye anobatanidzwa nyore nyore nema control systems kuti agadziriswe otomatiki. Ma Coriolis flow metres anodiwa nekuda kwekuyera kwawo kwakakwirira mukusimba kwakasiyana-siyana kwemvura uye huwandu, achiyera zvakananga kuyerera kwemvura. Izvi zvinoita kuti akwanise ma reagents akakosha kana kuti akakosha. Zvisinei, anoda mari yakawanda uye kugadziriswa. Positive displacement metres inobudirira nema reagents akasimba, anopa kunyatsojeka pakuyerera kwakaderera. Kusarudza kunofanirawo kufunga nezvekubatana nemaitiro ekuchenesa, kunyanya kune masisitimu edosing ane zvinodiwa zvakachena munzvimbo kana kuchinjana kwe reagent kakawanda. Midziyo inofanira kunge yakasimba kubata kukura kwescale, ngura, uye kugadzirisa nguva dzose kunowanikwa mufekitari yekugadzira zvicherwa.
Sei otomatiki ye flotation reagent dosing yakakosha muzvicherwa zvemazuva ano?
Kushandiswa otomatiki kwe flotation reagent dosing kunoita kuti pave nekuwedzera kwakarurama kwevaunganidzi neforomu zvichienderana nemhinduro dzemaitiro chaiwo. Kuchinja-chinja kwema feed grades kana shanduko muhunhu hweslurry zvinokurumidza kubhadharwa, zvichiwedzera kugadzikana kwemaitiro uye mwero wekudzoreredza. Mapuratifomu e otomatiki e dosing, achishandisa ruzivo rwenguva chaiyo kubva kumidziyo yekuyera kuyerera, anoderedza kushandiswa zvakanyanya kwe reagent uye kusashandiswa zvakakwana—zvinhu zviviri zvinotungamira mukusashanda zvakanaka. Kuchinja uku kunobvisa kukanganisa kwevanhu kuripo mukuongororwa kwemaoko uye kunoenzanisa kuendeswa kwemakemikari chaiwo nekuchinja kwe mineralogy, kuderedza mari yekushanda ukuwo kuchivandudza mwero wekudzoreredza simbi mukugadzirisa zvicherwa. Zvidzidzo zvakaongororwa nevezera zvinoratidza kuti kubatanidza advanced flow monitoring kunowedzera kushanda zvakanaka kwe reagent kusvika ku10% uye kunopa kuwedzera kunoyerwa muzvibereko zve concentrate.
Ndeapi mazano anobatsira kuderedza mari yekushandisa reagent pasina kuderedza mitengo yakakwira yekudzoserwa kwesimbi?
Kuongororwa kwehuwandu hwemvura nguva dzose, pamwe chete nekushanda kwemagetsi kwakavharwa, kunoita kuti chikamu chimwe nechimwe chetsvina chiwane huwandu hwakakodzera uye musanganiswa wema reagents. Kuongororwa kwematanho, umo ma reagents anowedzerwa pamatanho akati wandei ekutenderera pane kuti aendeswe ese panguva imwe chete, kunoderedza kushandiswa kwakawandisa uye kunopindura zvinodiwa zvinoshanduka mudunhu rese. Kusanganisa vaunganidzi, semuenzaniso, kuchinjana xanthate ne dithiophosphate, kunoita kuti kunangwa kwezvicherwa zvakasiyana-siyana kuve nyore uye kunoderedza kushandiswa kwemakemikari ese. Kuongororwa nguva dzose kwezvishandiso zvekuyera kunochengetedza kuvimbika kwekuyera uye kunoita kuti maresipi ekuyera arambe akaenzana nemamiriro ezvinhu ekushanda. Pamwe chete, nzira idzi dzekuderedza kushandiswa kwema reagent mukuchera dzinopa kuvandudzwa kwekugadzirwa kwesimbi nguva dzose uye nzira dzinooneka dzekuderedza mutengo we reagent, sezvakasimbiswa neongororo yezvedzidzo nemishumo yeindasitiri.
