Iimishini yokususa uphawu lomgwaqoikhethwe ngendlela engafanele ngenxa yokukhethwa okungalungile kombhede wesihlungi sezendlalelo ezintathu okuthinte ukucaciswa kwezinto ezikhethiwe zokuhlunga.I-FeTiO3 yenze ukumelana ne-asidi ne-alkali kwesihlungi se-RZG brand magnetite siphakeme kakhulu kunaleso se-magnetite evamile.Kodwa-ke, lolu hlobo lwesihlungi, isihlabathi se-garnet esingenalo uthuli se-RZG esicutshungulwe ngokuhambisana nezindinganiso zekhwalithi ephezulu kakhulu, sinesivinini sokuxazulula ngokushesha, futhi ngenxa yokuthi ungqimba oluphansi kakhulu lwezinto zokuhlunga lunosayizi omncane wezinhlayiya, lunamandla aqinile okuvimbela ukumiswa. okuqinile ekungeneni.Ukumaka ukuhlanza.Insimbi evamile izodlula ohlelweni lokuqhunyiswa kwesihlabathi nokususwa kokugqwala ngaphambi kokusetshenziswa.Ukuminyana 4. Ubulukhuni obungaphezulu bungafinyelela ku-30-80 microns.Eqinisweni, ukuhlanzwa kokumaka kusetshenziswa njenge-sandblasting abrasive engenalo uthuli.Ngenxa yamandla adonsela phansi athile aphezulu e-garnet, ngokuvamile yakhiwa isihlabathi se-quartz ye-anthracite ne-magnetite (noma i-garnet).Ngokuvamile, i-RZG engenalo uthuli i-garnet sandblasting abrasive (i-mery yemvelo) ingasetshenziswa.Izindleko ze-sandblasting ziphansi.Yehlisa futhi izindleko zokusebenzisa ikhasimende.

1. Ngenxa yokuqina okuhle kakhulu kanye nokuqina okuphansi kwe-RZG garnet sandblasting abrasive, ukuxuba ungqimba kuzokwenzeka esizeni ngemva kokugeza ngesihlanzi somugqa wokumaka.Izinzuzo zobuchwepheshe nezomnotho ezilethwa ukususwa kwemigqa yokumaka zigqame kakhulu, futhi sekuthathe indawo yensimbi yokuqala yensimbi (insimbi yethusi), isihlabathi somfula, nesihlabathi sequartz.Ukuhlanzwa kokumaka kukhulisa kakhulu ukumelana nokugqokwa kwesihlungi se-magnetite, kanye nobulukhuni begarnet obungenalo uthuli lwe-RZG 7. I-RZG i-garnet engenazo izintuli ikhethwa ku-iron-aluminium garnet rock ore yekhwalithi ephezulu, i-garnet engenaso uthuli i-sandblasting I-abrasive ayigcini nje ngokuba nayo. izici zekhwalithi ephezulu kanye nenani eliphansi, akukho protrusions engathandeki kanye nemigodi, isihlabathi se-RZG esingenalo uthuli singangena sijule emigodini nezingxenye ezingalingani zokuhlanza, kodwa futhi iqukethe izithako ze-Al2O3 ezizuzisayo.Ngemuva kokugeza okuningi ohlelweni lokukhiqiza, akunakwenzeka ukufeza ukungaxubi okuphelele ngemuva kokuhambisana ne-iso backwash.

2. Umshini wokuhlanza wokumaka ungaphinde ugweme i-silicosis ebangelwa i-silicon yamahhala futhi uthole kalula ibanga eliphakeme kakhulu le-sandblasting ye-Sa3.Ubuchwepheshe bokuhlunga bokuhlanzwa kokumaka besimanje buvuselelwa njalo.Phakathi kwazo, ucwaningo lwemithombo yokuhlunga enezingqimba ezintathu kanye nokukhuthazwa kwemiphumela yalo kulethe izinzuzo ezivelele zobuchwepheshe nezomnotho ekukhiqizeni.Ngakho-ke, isetshenziswe kakhulu yimibuthano yokwelashwa kwamanzi yasekhaya neyangaphandle.Lalela.Kodwa kulolu hlobo lwesihlungi, ungakhetha kanjani impahla yokuhlunga nokuthi ungayibeka kanjani?Njengoba igama lisho, umbhede wokuhlunga wesihlungi sezendlalelo ezintathu wakhiwe izendlalelo ezintathu zezinto zokuhlunga.Lesi sihlungi sinamandla okuvimbela ukungcola okukhulu, amandla aqinile okuvimbela izinto eziqinile ezimisiwe ukuthi zingangeni, isivinini esivumelekile sokuhlunga, ikhwalithi enhle yamanzi, kanye nomjikelezo omude wokuhlunga.Umbhede wokuhlunga wesihlungi esinezendlalelo ezintathu ngokuvamile senziwa i-anthracite, isihlabathi se-quartz ne-magnetite (noma i-garnet).

3. Izinto zokuhlunga ezinosayizi wezinhlayiya ezinkulu kanye namandla adonsela phansi amancane athile asatshalaliswa ongqimbeni olungaphezulu, okokuhlunga okunosayizi wezinhlayiyana eziphakathi nendawo namandla adonsela phansi athile asatshalaliswa phakathi, futhi okokuhlunga okunosayizi wezinhlayiyana ezincane namandla adonsela phansi amakhulu athile adonsela phansi. kusakazwa ungqimba olungezansi.Okusho ukuthi, isilinganiso sikasayizi wezinhlayiyana zezinto ezintathu zokuhlunga kancane kancane siyehla ukusuka phezulu kuye phansi.Ngale ndlela, umthamo wokuvala indle wombhede wokuhlunga ungasetshenziswa ngokugcwele, ngakho-ke umjikelezo wokuhlunga mude, futhi ngenxa yokuthi ungqimba oluphansi kakhulu lwento yokuhlunga lunosayizi wezinhlayiyana ezincane, lukwazi ukujwayelana ne-turbidity ephezulu noma ukushintshashintsha okukhulu kwe-turbidity.Lapho uklama ukucaciswa kombhede wesihlungi, ungabhekisela kokuhlangenwe nakho okuphumelelayo kwezinye izindawo.Ngaphezu kwalokho, kufanele iqinisekiswe futhi ilungiswe ngokuhlolwa ngokuya ngezimo zasendaweni, futhi akufanele isetshenziswe ngomshini.Ngenxa yokukhethwa okungalungile kombhede wesihlungi sezendlalelo ezintathu esithinta ukucaciswa kwezinto ezikhethiwe zokuhlunga, ukuxuba ungqimba kuzokwenzeka ngemva kokuba impahla yokuhlanza yokumaka ehlanekeziwe isiguquliwe.

4. Ngenxa yezinto ezingcolile zokuhlunga, ukugeleza kwamanzi okuxubekile, nosayizi wezinhlayiyana ezihlukene kanye namandla adonsela phansi athile wezinto zokuhlunga, akunakwenzeka ukufeza isendlalelo esingaxutshwe ngokuphelele ngemuva kokuwashwa ngemuva.Ngalesi sikhathi, ukukhetha kwe-high-density filter material magnetite njengodoti kubaluleke kakhulu.Uma udoti onamandla adonsela phansi akhethekile noma angafaneleki kusetshenziswa, kulula ukubangela ukuthi okokuhlunga kanye nodoti kubonakale kuxutshwe ngesikhathi senqubo yokuwashwa ngemuva, kanye nozibuthe womkhiqizo we-RZG Into yesihlungi se-iron ore ikhethwa ekucindezelweni okungavamile okungavamile. idwala le-metamorphic, elinokucaciswa okukhulu, okuqukethwe kwensimbi ephezulu, futhi liqukethe izingxenye ze-Al2O3 ezizuzisayo.Ukuhlanza kokumaka kukhulisa kakhulu ukumelana nokugqokwa kwezinto zokuhlunga i-magnetite.Iumenzi womshini wokuhlanza wokumaka's Ukumelana nokugqokwa kwemidiya yokuhlunga kazibuthe ye-RZG iphakeme ngo-20~35% kunaleyo yesihlungi semidiya samagnetite esivamile.Ngesikhathi esifanayo, i-FeTiO3 equkethwe (ephinde ichazwe njenge-FeOTiO2) ne-FeTiO3 yenza ukumelana ne-asidi ne-alkali yempahla yokuhlunga kamagnetite yomkhiqizo we-RZG ibe phezulu kakhulu kune-magnetite evamile.
