Misomali ndi zinyalala zotsala pambuyo pokonza mchere kapena kuchotsa mchere, zomwe zimayambitsa kuwonongeka kwina ku chilengedwe. Pambuyo posinthidwa kukhala ufa wosalala ndimphero ya tailings, mipata ingagwiritsidwe ntchito ngati zipangizo zomangira ndikugwiritsidwa ntchito pomanga, kumanga misewu ndi mapulojekiti ena.

Njira yopangira ufa wa tailings

Njira yopangira ufa wa tailings nthawi zambiri imagwiritsa ntchito njira yowuma yopera. Mizere nthawi zambiri imakhala ndi tinthu tating'onoting'ono ndipo imatha kuphwanyidwa kukhala ufa wokhala ndi ulusi wa 22-180μm ndi tailings millpopanda kuphwanyidwa.

Gawo 1: Kudyetsa

Zinyalala zimatumizidwa ndi elevator kupita ku hopper yosungiramo zinthu, ndipo hopper yosungiramo zinthu imatulutsa zinthuzo kenako n’kudyetsamphero ya tailings mofanana ndi chodyetsa.

Gawo 2: Kupera

Pamene mipata ikulowa mu mphero, zinthu zoyenera kutsukidwa zimachotsedwa ndi makina oyezera kuti zichotse ufa wosalala wa kukula kwa tinthu ta mipata, kenako zimalowa mu chosonkhanitsa kudzera mu payipi. Ufa woyenera umagwera mu mphero yoyimirira ya HLM kuti upukutenso.

Gawo 3: Zosonkhanitsa

Ufa wa tailings umalowa mu chosonkhanitsa fumbi la pulse kudzera mu duct yopumira yolumikizidwa ndi pulverizer, ndipo ufa wa tailings umalowa mu chosonkhanitsa fumbi kuti chipake. Mpweya wosonkhanitsa fumbi la pulse ndi kuyeretsa umalowa mu blower kudzera mu duct yotsala pamwamba pa chosonkhanitsa fumbi. Njira ya mpweya ikuzungulira. Kupatula kupanikizika kwabwino kuchokera ku blower kupita ku chipinda chopukusira, mpweya womwe uli mu payipi yonse umayenda pansi pa kupsinjika koipa, ndipo ukhondo wamkati umakhala wabwino.

Gulani fakitale yopangira zinthu kuchokera kwa wopanga mwachindunji

HCM ili ndi zaka zoposa 30 zogwira ntchito mumphero yoperaKafukufuku ndi Chitukuko, kupanga ndi kugulitsa, ndi makasitomala athu ali padziko lonse lapansi. Timapereka kusanthula kwathunthu deta ya mapulojekiti, ndikuthandizira mayankho opangidwa mwapadera.

Kuti mudziwe zambiri za mphero yopera kapena pempho la mtengo chonde titumizireni uthenga.
