Njira Yopezera Iron Ore pa Chindapusa

Madipoziti achitsulo akachotsedwa pansi. Ayenera kukonzedwa kuti awonjezere chitsulo ndikuchepetsa kuchuluka kwa mchere wa gangue. Njira imeneyi imatchedwa beneficiation. Malinga ndi mtundu wa zida processing, njira yothandizira chitsulo ikhoza kutenga njira zambiri, kapena zitha kutenga ziwiri zokha. Ndi ST Equipment & Technology (STET) olekanitsa triboelectric, mukhoza kupeza mankhwala apamwamba mu nthawi yochepa, pamtengo wotsika.

The Standard Iron Ore Beneficiation Process

Pali mitundu ingapo ya zida zamakono zolekanitsa zomwe zingagwiritsidwe ntchito popanga chitsulo chachitsulo chapamwamba. Ndi mtundu uliwonse wa zida, ndondomeko imayamba ndi kuphwanya ndikupera. Ndiye akhoza kutsatiridwa ndi kupatukana ndipo potsiriza ndi dewatering. Each of these steps is necessary for these processes and can cause the process to take longer and cost more.

Khwerero 1: Kuphwanya ndi Kupera

Pofuna kulekanitsa bwino zinthu zosiyanasiyana zomwe zimapezeka muzitsulo zachitsulo, choyamba ayenera kupukutidwa kukhala ufa wosalala kapena wosalala. Izi zimathandiza kuti zinthu zosiyanasiyana zimasulidwe kwa wina ndi mzake ndipo motero zimakhala zosavuta kupatukana. Kuphwanya ndi kugaya kumatha kuchitika kangapo ndipo kumachitika m'njira zingapo. The final objective is to create a fine powder that can be separated in the next steps.

Khwerero 2: kupatukana

Kulekanitsa ndi pamene tinthu tachitsulo timasiyanitsidwa ndi tinthu tina tomwe tingapezeke mu ufa. Ma particles/minerals enawa amachotsedwa kuti awonetsetse kuti ma depositi achitsulo amafika pachitsulo china. Pali mitundu yosiyanasiyana ya kulekanitsa - kulekanitsa mphamvu yokoka, maginito kupatukana, kupatukana kwa flotation, ndi olekanitsa kukula. Njira zolekanitsazi zingagwiritsidwe ntchito limodzi ndi wina ndi mzake kuti apange mankhwala apamwamba kwambiri.

• Kupatukana kwa Mphamvu yokoka: Amagwiritsa ntchito mphamvu yokoka ya chitsulo ndi gangue kuti alekanitse chitsulocho. Izi zimachitika mu mvula yamkuntho, ndi jig, tebulo, ozungulira, ndi zida zina zambiri zaukadaulo wolekanitsa. Kusiyanitsa kwa mphamvu yokoka kumagwiritsidwanso ntchito kulekanitsa zida zokulirapo kuchokera ku zida zabwino kwambiri, kotero imatha kuwirikiza ngati cholekanitsa kukula. Itha kugwiritsidwanso ntchito ngati chithandizo chisanachitike chisanachitike kupatukana kwa maginito kapena kuyandama.
• Kupatukana kwa Magnetic: Amagwiritsa ntchito maginito osiyanasiyana achitsulo ndi zida za gangue kuti alekanitse chitsulocho. Izi zitha kuphatikizira zida zaukadaulo zolekanitsa monga kulekanitsa kwamphamvu kwamphamvu kwamagetsi (LIMS), mkulu gradient maginito kulekana (Mtengo wa HGMS), kunyowa kwamphamvu kwambiri kwa maginito kulekana (MAWU), kapena kupatukana kwa maginito olowetsa maginito (Mtengo wa IRMS).
• Kupatukana kwa Flotation: Amagwiritsa ntchito makemikolo achitsulo kuti amamatire ku kuwira kwa mpweya. Reagent imasankhidwa yomwe ingagwirizane ndi chitsulo. Pamene reagent iyi imayambitsidwa ndi madzi, chitsulocho chimamatira ku thovu la mpweya. Flotation is usually used in conjunction with other separation processes and is the last step before dewatering.

Khwerero 3: Kuthira madzi

Njira zambiri zolekanitsa zokhazikika zimafuna kugwiritsa ntchito madzi kuti zigwire bwino ntchito. Masitepe onse akamaliza, zotsatira linanena bungwe ndi slushy, slurry kusasinthasintha. Kuti asandutse ma pellets, chotulutsa chiyenera kuchotsedwa madzi. The dewatering process can be done through vacuum filters or pressure filters.

The Triboelectric Separation process of Iron Ore Fines

Mosiyana ndi muyezo wabwino chitsulo ore kulekana ndondomeko, njira yolekanitsa ya triboelectric ndiyofulumira komanso yosavuta. Chitsulo chimadutsa masitepe awiri, njira yopera, ndi njira yolekanitsa. Because this iron ore beneficiation is water-free there is no dewatering needed.

Khwerero 1: Kupera ndi Kuphwanya

Madipoziti achitsulo amadutsa munjira yofanana yopera / kuphwanya monga momwe amachitira. The objective is to create a fine output that can be separated in the next stage.

Khwerero 2: Triboelectric Belt Separator

Mu sitepe iyi, chifukwa particles zabwino amadyetsedwa mu triboelectric lamba olekanitsa. Kuyika kwachitsulo kumadutsa mu mbali zazikulu za njira yolekanitsa ya electrostatic. Kuthamangitsidwa kwa particles, kulekana kwa tinthu ting'onoting'ono, ndi kulekanitsa mphamvu yokoka ya tinthu ting'onoting'ono. Zonsezi zimachitika ndi makina amodzi. Zotsatira zake ndi mankhwala owuma kwambiri omwe ali okonzeka kupeta.

STET Kulekana Technology Zida

Monga mukuwonera, ndondomeko STET amafuna zochepa kwambiri chisanadze mankhwala, kulekana ndi kamphepo, ndipo palibe chifukwa chothirira madzi. The STET olekanitsa ndi njira ina nzeru zida muyezo kulekana luso. Sikuti ndi othandiza, koma izo amachepetsa kuipitsa, amasunga ndalama, and makes it easy to get permits.

Timapereka zida zamakono zopangira mchere komanso zida zolekanitsa ma electrostatic kwa makasitomala athu padziko lonse lapansi. Timapereka zida zamakono zopangira mchere. Ndikufuna kuphunzira zambiri? Lumikizanani nafe lero!
