Muchigadzirwa chekugadzira zvicherwa, nhanho yekukuya ndiyo yakakosha dunhu nekudyara kukuru uye kushandiswa kwesimba. Iyo nhanho yekukuya inodzora shanduko yezviyo mune yese mineral processing kuyerera, iyo ine simba rakakura pachiyero chekudzoreredza uye chiyero chekugadzira. Naizvozvo, iwo mubvunzo wakanangana nekudzikisa mitengo uye kugadzirisa chiyero chekugadzira pasi peimwe giyo yekuyeresa mwero.
Kune marudzi maviri ekukuya nzira, yakavhurika-circuit grinding uye yakavharwa-circuit grinding. Ndedzipi dzakananga dzeidzi nzira mbiri dzekukuya? Ndeipi nzira yekukuya inogona kuona kushandiswa kwepamusoro-soro uye kugadzirisa chiyero chekugadzira? Mundima dzinotevera, tichapindura iyi mibvunzo.
Iyo chaiyo yenzira mbiri dzekukuya
Kuvhura-dunhu kugaya ndiko kuti, mukushanda kwekukuya, zvinhu zvinodyiswa muguyo uye zvinobudiswa mushure mekugaya, zvakananga muguyo rinotevera kana nzira inotevera.
Zvakanakira kuvhura-yedunhu kugaya zviri nyore kugadzirisa kuyerera uye kuderera kwekudyara mutengo. Nepo izvo zvazvakaipira zvakaderera kugadzirwa mwero uye hombe simba rekushandisa.
Kukuya-kuvharwa kwedunhu ndiko kuti, mukukuya, zvinhu zvinoiswa muguyo kuti zvigadzirwe mushure mekukuya, uye ore isina kukodzera inodzorerwa paguyo kuti igayiwe zvakare, uye ore yakafanirwa inotumirwa kune imwe nhanho inotevera.
Mabhenefiti makuru eakavharwa dunhu-kukuya ndeyepamusoro-inoshanda kupwanya mwero, uye mhando yekugadzira yakakwira. Munguva imwecheteyo, yakavharwa-yedunhu ine yakakura yekugadzira chiyero. Zvisinei, iyo yakaipa ndeyokuti kuyerera kwekugadzirwa kwevhavha-yedunhu kwakanyanyisa kuoma, uye kunodhura kudarika kuvhurika-circuit grinding.
Zvinhu zvisina kuenderana zvinodzokororwa pasi muchikamu chakavharwa-chekukuya kusvika chidimbu chechikamu chasvika. Paunenge uchikuya, mamwe maminerari anogona kutakurwa mumudziyo wekukuya, kuitira kuti simba remabhora ebhora rigone kushandiswa zvakanyanya sezvinobvira, kunatsiridza kushandiswa kwekushandisa kwekugadzira michina, kuitira kuti kugadzirwa kwekugadzira michina yekukuya kugadziriswe.
Midziyo yenzira mbiri dzekukuya
Mukusarudza kwemidziyo yekukuya, bhora regiyo harina simba rekudzora saizi yechikamu. Kune zviyo zvakakodzerwa zviyo uye zvisingakodzeri zviyo zvakakora muore drainage, izvo zvisina kukodzera kuvhurika kugaya midziyo yekukuya. Rob chigayo chakapesana, kuvepo kwesimbi matanda pakati pechivharo chakakora chinotanga kuputswa, kukwira kumusoro kwesimbi simbi senge nhamba yegrille, yakanaka zvinhu inogona kupfuura nepamukaha pakati pesimbi. Naizvozvo, chigayo chine simba rekudzora saizi yechikamu uye inogona kushandiswa seyakavhurika-yedunhu kugaya michina.
Kunyangwe chigayo chebhora chisina kugona kudzora saizi yechikamu pachayo, inogona kudzora saizi yechikamu nerubatsiro rwemidziyo yekuisa. Chigayo chinozorasa ore mumidziyo yemhando. Zvinhu zvakanaka zvakakodzerwa zvinopinda padanho rinotevera kuburikidza nekukuya-classifying kutenderera. Naizvozvo, yakavharwa-yedunhu kugaya isina kukwana coarse zvinhu zvinogona kupfuura nemuchigayo kakawanda, zvinofanirwa kunge zvakatsikirirwa kune inokwanisa particle size inogona kuburitswa ne classifying midziyo. Iko kune inenge isina muganho kune michina yekukuya inogona kusarudzwa muvharo yekukuya.
Kushandiswa kwenzira mbiri dzekukuya
Zvinoenderana nemhando dzakasiyana dzemaminerari, hunhu, uye zvakasiyana zvinodiwa zvekugadzirisa kuyerera, zvinodiwa zvekukuya fineness zvakasiyana. Mamiriro ezvinhu ane zvinyorwa zvakasiyana-siyana zvinosvika pachiyero chakakodzera chekuparadzanisa zvakare hazvina kufanana.
Mukuya-kutenderera kukuya, zvinhu zvakadzorerwa kumagetsi ekukuya zvinenge zvakakodzera. Kungogaya zvakare zvishoma kunogona kuva chigadzirwa chakakodzera, uye kuwedzera kwezvinhu muguyo, zvinhu kuburikidza neguyo nekukurumidza, nguva yekukuya yakapfupikiswa. Nokudaro, kuvharwa-kutenderera kunenge kuine maitiro ekugadzirwa kwepamusoro, chiedza chechiedza chepamusoro-kupwanya, kugovera kwakanaka uye yunifomu yekukura kwechidimbu. Kazhinji kutaura, flotation chirimwa uye magineti yekuparadzanisa chirimwa kazhinji inotora yakavharwa-yedunhu kugaya maitiro.
Iyo yakavhurika-yedunhu kugaya yakakodzera yekutanga kugaya. Chinhu chinobudiswa kubva pane chimwe chikamu cheguyo chinopinda mune imwe midziyo yekukuya uye inobva yakuyiwa (yakanaka). Nenzira iyi, chikamu chekutanga chechigayo chine chidiki chekupwanya reshiyo uye yakakwirira yekugadzira kugona, uye maitiro acho ari nyore.
Kupfupisa, zvinogona kuoneka kuti kusarudzwa kwekukuya maitiro kwakaoma, izvo zvinoda kutariswa mune zvakawanda zvinhu senge zvinhu zvenyama, mari yekudyara, uye tekinoroji maitiro. Zvinonzi varidzi vemigodhi vataurirane nevanogadzira michina yekugadzira migodhi vane magwaro ekugadzira migodhi kuitira kuti vasarasikirwa nehupfumi.
