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 amakhudza kwambiri kuchuluka kwa kuchira 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 ziti? 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 popera, mwachindunji mu mphero yotsatira kapena njira ina.
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 miyala yosayenerera imabwezeretsedwa kumpheroyo kuti ikagayidwenso, ndipo miyala yoyenerera imatumizidwa ku siteji yotsatira.
Ubwino waukulu wa chatsekedwa dera-akupera ndi mkulu-mwachangu kuphwanya mlingo, ndi kupanga khalidwe apamwamba. Munthawi yomweyi, kutsekeka-dera kumakhala ndi chiwopsezo chokulirapo. Komabe kuipa kwake ndikuti kutulutsa kozungulira kotsekeka kumakhala kovuta kwambiri, ndipo kumawononga ndalama zambiri kuposa kugaya kotseguka.
Zida zosagwirizana zimayikidwa mobwerezabwereza pagawo lotsekedwa lozungulira mpaka kukula kokwanira kwa tinthu tafikira. Pogaya, mchere wochuluka ukhoza kutumizidwa ku zipangizo zogaya, kuti mphamvu ya mphero ya mpira igwiritsidwe ntchito momwe zingathere, kupititsa patsogolo kugwiritsira 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. M'ngalande za ore muli mbewu zabwino zoyenerera komanso zomangira zolimba, zomwe sizoyenera zida zopukutira zotseguka. Kubera mphero ndizosiyana, kukhalapo kwa ndodo zachitsulo pakati pa chipika chakuda kudzakhala koyamba kusweka, kusuntha kwachitsulo chokwera 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 mu 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 zopera
Malingana ndi mitundu yosiyanasiyana ya mchere, khalidwe, ndi zofunikira zosiyanasiyana 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 kake ndi zosiyana. Mkhalidwe 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. Pokhapokha 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 kuphwanya-kuphwanya, zabwino ndi yunifolomu kugawa tinthu kukula. Nthawi zambiri, chomera choyandama ndi cholekanitsa maginito nthawi zambiri 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.
