Dope resaw musanganiswa weupfu hwematombo nemvura zvinogadzirwa panguva yekucheka nekupukuta marble negranite. Nzvimbo zhinji dziri kuchamhembe kwenyika yedu dzinokosha pakugadzira matombo, uye huwandu hwakawanda hwedope resaw hunogadzirwa gore rega rega, uye kuunganidzwa kwaro kunotora nzvimbo yakakura yezviwanikwa zvevhu. Dope rematombo rine hunhu hwakanaka uye rakaoma kurasa. Zviri nyore kubhururuka mudenga kana mhepo ine simba, uye rinoyerera murwizi nemvura inonaya mumazuva ekunaya, zvichikonzera kusvibiswa kwakanyanya kwezvakatipoteredza.
Zvicherwa zvikuru zvegangue mudhaka resaw zvinosanganisira feldspar, quartz, calcite, dolomite, amphibole, nezvimwewo. Zvicherwa zvikuru zvesimbi netsvina zvinosanganisira iron silicate senge mechanical iron, magnetite, iron oxide, pyrite, uye biotite. Parizvino, nzira yakakwana yekushandisa saw ivhu ndeyekugadzira zvidhinha zvekongiri zvine mhepo uye kugadzira zvinhu zveceramic mushure mekubvisa tsvina. Yekutanga ine kugona kukuru kwekugadzirisa uye yekupedzisira ine mabhenefiti makuru ehupfumi.
Tsvagiridzo yekubatsira
Muchinyorwa chino, tsvakiridzo yakakwana yekushandiswa uye kuyedzwa kwekubatsirika inoitwa kune inomiririra saw mud munzvimbo yeJining. Zvicherwa zvinokosha mu saw mud i feldspar, mechanical iron, magnetic iron, nezvimwewo, uye tsvina inokuvadza i limonite, biotite, muscovite, calcite, dolomite, hornblende, nezvimwewo. Saizi yezvinhu haina kuenzana, zvidimbu zvakakora zvinobva pa 1-4mm uye mamwe -0.037mm fine mud. Pakati pazvo, mechanical iron inogadzirwa panguva yekugadzirisa uye magnetic iron iri mu raw ore zvinogona kupatsanurwa nemagineti kuita zvigadzirwa zve iron concentrate. Mushure mekupatsanurwa kwakasimba kwemagineti, tsvina ine iron senge limonite, biotite, uye amphibole inogona kubviswa. Zvigadzirwa zvematombo concentrate, chikamu chimwe nechimwe che magnetic tailings chinogona kushandiswa sezvidhinha zvine mhepo kana simende, kuitira kuti chinangwa chekushandiswa kwakazara chibudirire.
1.Kusarudza kuyerera kwemaitiro
Kusanganisa hunhu hwesawdust sampuro kuti uone maitiro ekunatsa: dombo risina kuchekwa rinoseferwa kuburikidza ne30 meshes-+30 mesh coarse-grain grinding kusvika -30 mesh.
——-30 mesh yakasanganiswa simbi yekuparadzanisa nedhiramu magnetic separator + flat plate + vertical ring + vertical ring strong magnetic iron removal-concentrate inokamurwa kuita +300 mesh medium-grain feldspar concentrate products uye -300 mesh fine mud.——Tsvina yakatsetseka inoshandiswa kubvisa simbi kaviri kuburikidza ne electromagnetic slurry kuti iwane chigadzirwa che fine powder-grade concentrate.
2.Bvunzo rekupatsanurana kwemagineti raw ore
Mhangura isina kuchekwa yakasefewa nemambure makumi matatu, uye mhedzisiro yekuongorora inoratidzwa muTafura 1.
Tafura 1. Mhedzisiro yeKubatsirwa uye Kuongororwa kweMuedzo
Gadzirai simbi ine goho re17.35% kusvika -30 mesh, sanganisai nechigadzirwa pasi pesefa, mobva maita nzira yekuparadzanisa simbi ine magineti yedhiramu magnetic separator + flat plate + vertical ring + vertical ring. Kuyerera kwesimbi kunoratidzwa muMufananidzo 1, uye mhinduro dzebvunzo dzinoratidzwa muTafura 2.
Mufananidzo 1. Kuyerera kwemaitiro ekuyedza kwekupatsanurwa kwemagineti kwesimbi isina kugadzirwa.
Tafura 2. Mhedzisiro yebvunzo yekupatsanurwa kwemagineti yakajairika
Mhangura isina kucheneswa inoongororwa + kukuya simbi + nzira yekuedza kubvisa simbi katatu, uye zvigadzirwa zvepakati nepazasi zvinogona kuwanikwa negoho re92.57%, huwandu hweFe2O3 hwe0.525% uye kuchena kwe36.15%. Inofanira kufungwa nezvekuchenesa iron oxide nesimbi silicate mumatope matete nemuchina wemagetsi wepakati nepakati, wepamusoro-soro mushure mekupatsanurwa.
3. Kubviswa kwesimbi kubva mumatope akatsetseka
Chikamu chechipiri cheLihuan chinoburitswa kubva mutsvina yakatsetseka iri pasi pe -300 mesh kuburikidza nekupfuura, uye maitiro ekubvisa iron kaviri nemuchina we electromagnetic slurry anoshandiswa kuwana chigadzirwa che fine powder concentrate. Kuyerera kwemaitiro kunoratidzwa muMufananidzo 2, uye mhedzisiro yebvunzo inoratidzwa muTafura 3.
Mufananidzo 2. Kuyerera kwemaitiro ebvunzo yekubvisa simbi yematope akatsetseka
Tafura 3. Chiratidzo chekubvisa simbi yematope akatsetseka
Mushure mekuyera Lihuan concentrate, kuchena kwe +300 mesh medium-grain feldspar concentrate kwakawedzera kubva pa36.15% kusvika pa56.49%, uye kuchena kwematope matete kwakaderera kusvika pa23.07%. -300 mesh fine sludge inobviswa musimbi kaviri ne electromagnetic slurry, uye chigadzirwa che ceramic-grade fine powder chine goho re 42.31% uye kuchena kwe 41.80% chinogona kuwanikwa.
3. Muedzo wekuita kwese
Mamiriro ebvunzo akakwana uye zviratidzo zvekuita bvunzo yese yemaitiro.
Mufananidzo 3. Maitiro ese ekuyedza kucheka matope
Tafura 4. Zviratidzo zvekuedza zvemaitiro ese
Chinobatanidzwa: Tembiricha yemabhisikiti 1200℃
Matombo edope akaseferwa + akakuyiwa + asina simba ekupatsanurwa kwemagineti + flat plate + vertical ring + vertical ring + grading electromagnetic slurry magnetic separation process kuti awane iron ore ine goho re0.32% uye TFe grade ye62.35%. Negoho re38.56% uye kuchena kwe54.69% yezvigadzirwa zve feldspar concentrate zvepakati-grain ceramic grade uye goho re42.31% yegoho re41.80% fine powder ceramic grade concentrate; goho rese re magnetic tailings i18.81%, Rinogona kushandiswa sezvinhu zvekugadzira zvidhinha zvine mhepo.
Maitiro aya ehunyanzvi anobvumira kushandiswa kwakazara kwemasukisi emudove, uye anogona kuwana mabhenefiti epamusoro ehupfumi uye kukosha kwekuchengetedzwa kwezvakatipoteredza munharaunda.
