Nickel ndi chitsulo chofunikira chopanda chitsulo chomwe chimagwiritsidwa ntchito m'njira zosiyanasiyana. Chimapezeka makamaka mu nickel sulfide ndi nickel oxide ores. 30% ya zinthu za nickel ndi sulfide ores ndipo 70% ndi laterite nickel ores. Chifukwa cha kufunikira kwakukulu kwa nickel komanso kuchepa pang'onopang'ono kwa nickel sulfide ore, chitukuko cha laterite nickel ore chikuwonetsa chizolowezi champhamvu. Pakuwonongeka kwa sulfuric acid ya laterite nickel ore, zinyalala za laterite nickel ore zakhala chinthu choletsa njira yochotsera nickel yonyowa. Monga wopanga wanikeli woswekamphero yopukutira yowongoka, HCMilling (Guilin Hongcheng) idzakupatsani njira zobwezeretsera ndikugwiritsanso ntchito zinyalala za lateritic nickel ore.

Njira yobwezeretsera ndikugwiritsanso ntchito zotsalira za zinyalala za lateritic nickel ore ndikuziyika mu calcine lateritic nickel ore waste residue pa 160~900 ℃ kwa mphindi 20~120, ndipo mutaziziritsa mwachilengedwe, muzimupera kukhala ufa ndi zotsalira za sieve ya 0.08 mm zosakwana 10% kudzera. nikeli woswekamphero yopukutira yowongokakukonzekera zipangizo zopangira simenti ya magnesium, zinthu zoyeretsera pansi pa msewu kapena putty yopaka utoto pakhoma. Njira zenizeni zobwezeretsera ndikugwiritsanso ntchito slag ya laterite nickel ore ndi izi:

(1) Nikeli wothira madzi wokhala ndi chinyezi cha 12% ~ 18% (tinthu tating'onoting'ono tomwe tili pansi pa 3 mm timaposa 70%, ndipo kukhuthala kwake kumakhala kolimba) umaumitsidwa ndi chowumitsira chowira mwachangu, chinyezicho chimachepetsedwa kufika pa 3%, kenako chimayikidwa m'malo osungira pambuyo pochotsa chitsulo m'magawo ambiri, ndipo zosakanizazo zimayikidwa munikeli woswekamphero yopera.

(2) Nthaka youma ya nickel imalowetsedwa mu mphero ya nickel slag kuti itulutsidwe ndi kuphwanyidwa pambuyo poyika batching (kuwonjezera kuchuluka koyenera kwa choyambitsa), kenako nkulekanitsidwa ndi mpweya wolekanitsidwa. Tinthu tating'onoting'ono timabwezedwa kunikeli woswekawoongokachozunguliramphero, ndipo ufa wotsalawo umalowa mu chosungira ufa ndi mphepo kuti ukonze chinthu chomalizidwa, chomwe chimayikidwa mu malo osungira. Ufa wosalala wokhala ndi malo enaake a <200m2/kg umabwezeretsedwa ku mphero yopukusira ya nickel slag vertical kenako umaphwanyidwa. Ufa wina wosalala kwambiri wokhala ndi malo enaake a >450m2/kg umasonkhanitsidwa ndi chosonkhanitsa fumbi kenako nkunyamulidwa mwachindunji kupita ku nyumba yosungiramo zinthu zomalizidwa.

Chinyezi cha Laterite nickel ore kwenikweni ndi chisakanizo cha calcium sulfate, magnesium hydroxide, calcium silicate hydrate ndi calcium aluminate hydrate. Pambuyo pouma kapena kutentha pang'ono, chisakanizo cha anhydrous calcium sulfate, magnesium oxide, dicalcium silicate ndi calcium aluminate chimapezeka. Chili ndi makhalidwe ofanana ndi simenti ya Portland, simenti ya magnesite ndi gypsum. Ndi mtundu watsopano wa zinthu zomangira ndipo zimagwiritsidwa ntchito kwambiri mumakampani omanga. Njira yobwezeretsa ndikugwiritsanso ntchito chinyezi cha laterite nickel ore ndi yosavuta, siigwiritsa ntchito kutentha kwambiri, kuthamanga kwambiri komanso zipangizo zodula, ndipo ndi yosavuta kuyigwiritsa ntchito. Njira yanikeli woswekawoongokachozungulirampheroNdi gawo lofunika kwambiri pakubwezeretsa, kugwiritsanso ntchito, ndi kugwiritsa ntchito chuma cha laterite nickel slag, zomwe zimapangitsa pafupifupi theka la mphamvu yonse yogwiritsidwa ntchito, kuti muchepetse ndalama zopangira, kugwiritsa ntchito mphamvu, ndikuwonjezera luso lopukuta nickel slag. Tikukulimbikitsani kuti musankhe mphero yopukutira ya nickel ore kuti mulowe m'malo mwa mphero yachikhalidwe ya mpira ngati zida zazikulu zobwezeretsanso ndikugwiritsanso ntchito mphero ya laterite nickel ore slag.nikeli wosweka zabwino kwambirimpheronjira ya nikeli woswekamphero yopukutira yowongoka yavomerezedwa, ndipo kusalala koyenera kwa kugaya kumachitika mwa kusintha bwino chogawa kuti zitsimikizire kuti ufa wosalala kwambiri wokhala ndi malo enaake pamwamba pake ukukwaniritsa zofunikira za mphamvu ndi ntchito zomwe zimagwiritsidwa ntchito pang'ono, kuti tipewe vuto la kuchuluka kwa ufa wosalala kapena kugwiritsa ntchito mphamvu zambiri chifukwa cha kupukutira kwambiri kwa kugaya mpira kwachikhalidwe.

HLM mndandanda wa nickel slagmphero yopukutira yowongoka Chopangidwa ndi HCMilling (Guilin Hongcheng) chagwiritsidwa ntchito kwambiri pamitundu yosiyanasiyana ya zinyalala zobwezeretsanso ndi kubwezeretsanso zinyalala kuti apange zinthu zobiriwira zolimbitsa simenti, zomwe zimapereka chithandizo chabwino cha zida zobwezeretsanso ndikugwiritsanso ntchito zinyalala za laterite nickel ore. Ngati mukufuna kubwezeretsanso zinyalala za laterite nickel ore ndi nikeli woswekamphero yopera, chonde funsani HCM kuti mudziwe zambiri za zida.
