Kubva kuma1990, nyika dzekunze dzakatanga kudzidza tekinoroji yehungwaru yekubatsira uye dzakaita kufambira mberi mune zvedzidziso, zvakaita seGunsonSortex muUK neOuto-kumpu muFinland. uye RTZOreSorters, nezvimwewo, dzakagadzira nekugadzira mhando dzinopfuura gumi dzemaindasitiri ekugadzira ma photoelectric sorters, radioactive sorters, nezvimwewo, uye dzakashandiswa zvinobudirira mumunda wekusarudza simbi dzisina ferrous nesimbi dzinokosha, asi nekuda kwemutengo wakakwira, kunyatsorongeka kwakaderera, kugona kwekugadzirisa kudiki, uye kwakaganhurirwa mukusimudzira nekushandisa.
Zvichienzaniswa nenyika dzekunze, tsvakiridzo yetekinoroji yakabatana munyika yangu yakatanga kunonoka, uye nzvimbo yekutsvagisa yakamanikana. Munenge mugore ra2000, mimwe michina yekutsvagisa yakaonekwawo mumusika wemumba, kunyanya kupatsanura mavara, kupatsanura infrared, kupatsanura magetsi, nezvimwewo, zvinonyanya kushandiswa kupatsanura zviyo, chikafu, tii, mishonga, makemikari, bepa, girazi, kupatsanura marara nedzimwe nzvimbo dzeindasitiri, asi simbi dzinokosha nedzisingawanzoonekwi dzakadai segoridhe, ivhu risingawanzoonekwi, mhangura, tungsten, marasha, simbi isina simba yesimbi, nezvimwewo hazvigone kusarudzwa zvakanaka uye kuraswa pachine nguva, kunyanya mumidziyo yakaoma yekurasa miswe ichiri isina chinhu.
Parizvino, migodhi yemuno haina michina inoshanda yekurasa masimbi asina simba emagnetic, masimbi asina ferrous, nezvimwewo, zvichinyanya kutsamira panzira yekutanga yekuronga nemaoko uye nzira yekuparadzanisa magineti, uye saizi yezvikamu zvekuronga inowanzova pakati pe20 ne150 mm. Simba rakawanda uye mutengo wakakwira. Kune zvicherwa zvine musiyano mudiki muruvara rwechitarisiko, kupenya, chimiro, uye huwandu hwematombo nematombo asina kucheneswa, kushanda zvakanaka kwekusarudza kwakaderera, kukanganisa kwakakura, uye zvimwe hazvigone kusiyanisa. Kune magnetite, nzira yekuparadzanisa magineti inogona kushandiswa kukanda miswe, asi kune masimbi ane hunhu husina simba hwemagnetic, masimbi asina ferrous, nezvimwewo, kukanganisa kwekuparadzanisa kwakakura, kushanda zvakanaka kwekuparadzanisa kwakaderera, uye kune kutambisa kwakakomba kwezviwanikwa.
Muchina wekuronga masensa wakangwara wakakodzera kurapa matombo asati agadzirwa nesimbi isina kucheneswa zvakanyanya uye kupatsanurwa kwakanaka pakati pematombo akakomberedza nematombo anobatsira mushure mekupwanywa.
01
Kuderedza huwandu hwemigodhi hwakatarwa kwakaenzana nekuwedzera huwandu hwesimbi dzinowanikwa mumaindasitiri;
02
Deredza mutengo wekukuya nekuvandudza zvirimwa zvinotevera;
03
Kugona kwekugadzirisa kwehurongwa kunogona kuvandudzwa kana michina yekukuya yekutanga ikaramba isina kuchinja;
04
Kuvandudza giredhi rakasarudzwa kunobatsira pakudzikamisa nekuvandudza mhando yemafuta anonyungudutsa uye kuderedza mari yekunyungudutsa;
05
Deredza huwandu hwemadhaka akachekwa zvakanaka, deredza mari yekugadzira nekugadzirisa madhaka akachekwa, uye vandudza kuchengetedzeka kwakakomberedza nzvimbo yedhamu.
Semuenzaniso, migodhi yegoridhe: parizvino, zviwanikwa zvegoridhe zvenyika yangu zvakaratidzwa zvine matani 15,000-20,000, zviri panhamba yechinomwe pasi rose, negoridhe rinobuda pagore rinodarika matani 360, goridhe remumatombo rinosvika 60%, uye avhareji yedhipoziti yesimbi yesimbi inosvika 5%. Inenge g/t, goridhe remumatombo rinosvika matani mabhiriyoni matatu. Rave guru mugadziri wegoridhe pasi rose. Zvisinei, nzira yekuwedzera goridhe munyika yangu ichiri kushandisa nzira yechinyakare yekuisa goridhe mugomba. Hapana nzira inoshanda yekukanda miswe usati wapwanya nekukuya. Basa rekupwanya, kukuya nekukuya rakakura, uye mutengo wekuwedzera uchiri wakakwira. Mwero wekurasikirwa kwemugodhi unopfuura 5%, mwero wekudzoreredza nekunyungudutsa goridhe ungangoita 90%, mutengo wekuwedzera wakakwira, mwero wekudzoreredza zviwanikwa wakaderera, uye kuchengetedzwa kwezvakatipoteredza kwakaderera.
Mushure mekurasa zvinhu nekushandisa sensor sorting yakangwara, dombo rakasarudzwa rinogona kuita 50-80% yesimbi isina kucheneswa yakasarudzwa, zvichiwedzera goridhe rakasarudzwa ka3-5, uye zvichideredza huwandu hwevashandi vari mufekitari yekushongedza ne15-20%, kuwedzera kwe25-30% kwematombo asina kucheneswa uye 10-15% mukugadzirwa kwesimbi.
Mutengo wekupwanya nekukuya unogona kuponeswa neanopfuura 50%, huwandu hwemakemikari hunotevera hunogona kuderedzwa neanopfuura 50%, kushanda zvakanaka kwekugadzira kunovandudzwa zvikuru, kukosha kwekushandisazve marara ematombo kunovandudzwa, kukuvara kwezvakatipoteredza kunoderedzwa, uye mabhenefiti ehupfumi anovandudzwa zvikuru.
Hukuru hwezvikamu zve "particles" zve "intelligent sensor sorting" hunogona kusvika pa1mm kusvika 300mm, uye "sensor" inogona kuona zvidimbu zve "ore" zvinosvika 40,000 pasekondi. Zvinongotora ms shoma chete pachidimbu chimwe nechimwe che "ore" kubva pakuona "receiving sensor" kusvika pakuraira kwekuronga kwakawanikwa ne "actuator". Zvinongotora ms shoma chete kuti "injection module" ipedzise kushanda kamwe chete. Hukuru hwe "processing" hwemuchina mumwe chete hunogona kusvika 400 t/h, uye hunhu hwe "processing" hwemuchina mumwe chete hunogona kusvika matani mamiriyoni matatu pagore, zvakaenzana nehukuru hwe "migodhi yepakati nepakati nehombe".
Midziyo yekuronga sensor ine hungwaru inogona kuchinja software zviri nyore uye preset sorting thresholds online, uye inopindura kuchinja kwemhando nehuwandu hweore mbishi nenguva, izvo zvisingagone kuwanikwa pamichina yekuronga yechinyakare. Chero bedzi ore mbishi yasvika padanho rakati rekusanduka muchikamu chekupwanya, kunyangwe iri dhigiri rekupatsanura dombo rakatenderedza kana gangue, kana kuti concentrate yekupedzisira yagadzirwa zvakananga, inonyanya kushandiswa kune akasiyana masimbi esimbi (non-magnetic kana weakly magnetic iron ore, copper, lead, Pre-selection uye waste disposation ye zinc, nickel, tungsten, molybdenum, tin, rare earth, gold, nezvimwewo), marasha uye mamineral asiri esimbi akadai setalc, fluorite, calcium carbonate, dolomite, calcite, apatite, nezvimwewo. Huwandu hwe coarse concentrate inopinda mukuita kunotevera hunoderedzwa zvakanyanya, uye giredhi rinovandudzwa, izvo zvinogona kuderedza zvakanyanya mutengo wekukuya nekuwedzera. Intelligent sensor beneficiation haienzaniswi netsika yekuronga nemaoko, magnetic separation, uye photoelectric separation maererano nekururama kwekuzivikanwa, kumhanya kwekupindura, kushanda zvakanaka pakuronga, uye kugona kwekugadzirisa. Kuronga kwekunzwa kwakangwara kunoratidza tekinoroji yemazuva ano yekunzwa uye tekinoroji yedhijitari, uye kwave kuri nzira huru yekuvandudza kusarudzwa kwezvicherwa.
Zviwanikwa zvezvicherwa zvekuChina zvinonyanya kuve matombo asina kusimba, uye kugona kuchengetera zvinhu zvakawanda. Maitiro ekurasa marara pachine nguva, kuvandudza kushanda kwekugaya nekunatsa zvinotevera, uye kuderedza mutengo wekunatsa, uye kupindura zvinodikanwa zvenyika zve "kuvaka migodhi yakangwara nemigodhi yegirini", zvichave tsika isingadzivisiki mukusimudzira indasitiri yemigodhi yenyika yangu. Naizvozvo, kugadzirwa kwemidziyo yekuronga yakangwara yakakodzera zvicherwa zvemumba kuri pedyo, uye tarisiro yemusika ichave yakakura kwazvo.
