M'mafakitale opangira mchere, gawo logaya ndilo gawo lalikulu lomwe lili ndi ndalama zambiri komanso kugwiritsa ntchito mphamvu.Gawo logaya limayang'anira kusintha kwambewu mumayendedwe onse a mineral processing, omwe ali ndi mphamvu yayikulu pakuchira komanso kuchuluka kwa kupanga.Chifukwa chake, ndi funso loyang'ana kwambiri kuti muchepetse ndalama ndikukweza kuchuluka kwa zopanga pansi pamiyezo inayake yogaya yabwino.
Pali mitundu iwiri ya mphero, mphero yotseguka ndi yotseka yozungulira.Kodi zenizeni za njira ziwiri zogaya izi ndi zotani?Ndi njira iti yopera yomwe ingazindikire kugwiritsa ntchito bwino kwambiri ndikuwongolera kuchuluka kwa kupanga?M’ndime zamtsogolo, tidzayankha mafunso amenewa.
Zodziwika za njira ziwiri zopera
Kutsegula-kuzungulira kozungulira ndiko kuti, pogaya, zinthuzo zimadyetsedwa mu mphero ndikutulutsidwa pambuyo pogaya, mwachindunji mu mphero yotsatira kapena ndondomeko yotsatira.
Ubwino wa mphesa wotsegulira ndikuyenda kosavuta komanso kotsika mtengo.Ngakhale kuipa ndi otsika kupanga mlingo ndi lalikulu mowa mphamvu.
Kugaya kotsekeka ndiko kuti, m’ntchito yoperayo, zinthuzo zimadyetsedwa m’mphero kuti zigawidwe m’magulu pambuyo pogaya, ndipo mwala wosayenerera umabwezedwa ku mphero kuti ukagayenso, ndipo miyala yoyenerera imatumizidwa ku siteji yotsatira.
Ubwino waukulu wa chatsekedwa dera-akupera ndi mkulu-mwachangu kuphwanya mlingo, ndi kupanga khalidwe ndi apamwamba.Munthawi yomweyi, kutsekeka-dera kumakhala ndi kuchuluka kokulirapo.Komabe kuipa kwake ndikuti kutulutsa kotsekeka kozungulira kumakhala kovuta kwambiri, ndipo kumawononga ndalama zambiri kuposa kugaya kotseguka.
Zinthu zosasinthika zimayikidwa mobwerezabwereza pagawo lotsekedwa lozungulira mpaka kukula kokwanira kwa tinthu.Pogaya, mchere wochuluka ukhoza kutumizidwa ku zipangizo zogaya, kuti mphamvu ya mphero ya mpira igwiritsidwe ntchito momwe zingathere, kupititsa patsogolo kugwiritsa ntchito bwino kwa zipangizo zogaya, kuti kupanga bwino kwa zipangizo zogaya zikhale bwino.
Zida ziwiri zopera njira
Mu kusankha zida akupera, mpira mphero alibe mphamvu kulamulira tinthu kukula.Pali mbewu zabwino zoyenerera ndi mbewu zosakanizika zosayenerera mu ngalande ya ore, zomwe sizoyenera zida zopukutira zotseguka.Kubera mphero ndizosiyana, kukhalapo kwa ndodo zachitsulo pakati pa chipika chakuda kudzakhala koyamba kusweka, kusuntha kwazitsulo zachitsulo ngati ma grille angapo, zinthu zabwino zimatha kudutsa kusiyana pakati pa ndodo zachitsulo.Choncho, ndodo mphero amatha kulamulira tinthu kukula ndi angagwiritsidwe ntchito ngati lotseguka dera akupera zida.
Ngakhale mpira mphero alibe mphamvu kulamulira tinthu kukula palokha, akhoza kulamulira tinthu kukula mothandizidwa ndi classifying zida.Mpheroyo idzatulutsa miyala muzitsulo zamagulu.Zinthu zabwino zoyenerera zimalowa gawo lotsatira kudzera m'magulu ogaya.Choncho, chatsekedwa dera akupera osayenera coarse zakuthupi angadutse mphero kangapo, ayenera pansi kwa oyenerera tinthu kukula akhoza kutulutsidwa ndi gulu zida.Pali pafupifupi palibe malire kwa zipangizo pogaya kuti akhoza kusankhidwa mu chatsekedwa siteji akupera.
Kugwiritsa ntchito njira ziwiri zakupera
Malingana ndi mitundu yosiyanasiyana ya mchere, khalidwe, ndi zofunikira zosiyana za kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kakeMkhalidwe wa zipangizo zomwe zili ndi zolemba zosiyanasiyana zomwe zimafika pamlingo woyenera wa dissociation sizili zofanana.
Pakupera kozungulira, zida zobwerera ku zida zogaya zimakhala pafupifupi zoyenerera.Only pang'ono kachiwiri akupera akhoza kukhala oyenerera mankhwala, ndi kuwonjezeka kwa zipangizo mu mphero, zinthu kudzera mphero mofulumira, akupera nthawi adzafupikitsidwa.Choncho, otsekedwa-dera akupera ali ndi makhalidwe apamwamba zokolola, kuwala mlingo wa mopitirira muyeso kuphwanya, zabwino ndi yunifolomu kugawa tinthu kukula.Nthawi zambiri, chomera choyandama ndi cholekanitsa maginito chimagwiritsa ntchito njira yopera yotseka.
Kupukuta kotseguka ndikoyenera kugaya koyamba.Zinthu zomwe zimatulutsidwa m'chigawo chimodzi cha mphero zimalowa m'ziwiya zina zoperayo kenako n'kuzipera (zabwino).Mwa njira iyi, gawo loyamba la mphero ya ndodo imakhala ndi chiŵerengero chochepa chophwanyidwa ndi mphamvu zambiri zopangira, ndipo ndondomekoyi ndi yosavuta.
Pomaliza, zitha kuwoneka kuti kusankha kwa mphero kumakhala kovuta, komwe kumayenera kuganiziridwa pazinthu zambiri monga zinthu zakuthupi, ndalama zogulira, ndi njira zaukadaulo.Akuti eni eni a mgodiwo afunsane ndi opanga zida zogwirira ntchito omwe ali ndi ziyeneretso za kapangidwe ka migodi kuti apewe kuwonongeka kwachuma.
