Macdanta birlabta waxay leedahay sifooyin birlabeed oo xooggan, oo ay ugu horreeyaan macdanta birlabta hal-hal ah, macdanta birlabta vanadium, macdanta birlabta magnetite iyo birta oksaydhka isku dhafan, macdanta birlabta badan ee magnetite, iwm. Magnetite-ku wuxuu u qaybsan yahay granules qallafsan, walxo dhexdhexaad ah oo khafiif ah, walxo khafiif ah oo ku jira magnetite, halkaas oo macdanta birta lagu kaydiyo miraha qallafsan iyo walxaha dhexdhexaadka ah ee khafiifka ah ay jabto. Ka dib habka murrization, waxay heli kartaa xoogag bir ah oo tayo leh oo leh habka xulashada birlabta oo daciif ah. Macdanta birlabta ee micronardised waxay u baahan tahay warshad khafiif ah ilaa monomer ku filan si loo gaaro tilmaamayaasha qaybinta oo wanaagsan.
Xalka JCTN ee Walt oo ah dheecaan birlab ah oo si birlab ah loo sameeyay waa kala sooc birlab qoyan oo loogu talagalay biyo raacinta iyo nadaamaynta macdanta magnetine, kaas oo ku habboon kala soocidda kala-soocidda badeecada buuxinta ee buuxinta; Iyo fiirsashada macdanta ka hor shaandhaynta; magnetite wuxuu galaa xulashada ka hor shaandhaynta ka hor shaandhaynta ka hor shaandhaynta ka hor shaandhaynta; xulashada ugu dambeysa ee magnetite way adag tahay in la hagaajiyo walxaha yaryar ee ikhtiyaarka magnetic-ga caadiga ah, walxaha yaryar, macdanta birta waxay leedahay saameyn xulasho oo muhiim ah.
Kala-soocidda Birlabta ee Muhiimka ah ee JCTN
Astaamaha farsamada ee ugu muhiimsan
■ Ku xidhnaanta isku-dhaca macdanta iyo qulqulka waxaa loo isticmaalaa in lagu gaaro ujeeddada macdanta isku midka ah;
■ Isticmaalka nooc cusub oo ah jir jeexdin aan taxane lahayn iyo wareegga rogidda ee rogidda ayaa hagaajin kara soo kabashada macdanta;
■ Qaab-dhismeed biyo-raacin oo marxalado badan leh iyo daah biyo sare ah ayaa lagu bixiyaa godka cusub ee aan taxanaha lahayn, kaas oo si buuxda u raaci kara macdanta dusha sare ee durbaanka;
■ Qaado qaab-dhismeed birlab oo 240 ° -270 ° ah oo ballaaran oo ay ku jiraan qaab-dhismeed birlab badan oo birlab ah, oo ay weheliso birlab-gacmeedka ku jira kartoonka, si loo gaaro macdan, duub iyo kacsanaan birlab ah, oo hoos yimaada biyaha lagu luqluqdo, si ku filan uga saar wasakhda ku jirta cufnaanta, hagaaji booska Seiko.
■ Qaab-dhismeedka macdanta waxaa loo isticmaalaa in lagu gaaro uruurinta macdanta inta la isticmaalayo qaab-dhismeedka macdanta.

Codsiyada
1. Tusaale ahaan codsiga magnetite ee Sichuan
Qaybo fiican oo birlab ah oo Sichuan ah, macdan bir ah oo yar yar oo la dhigo, habka wax soo saarka dhabta ah waa gabal shiidi ah oo jilicsan -200 mesh 65%, xulasho birlab oo daciif ah 1500GS xulasho qallafsan - 1200GS xulasho, xoogga birta TFE waa 61.24%, waxaana loo heli karaa oo keliya in ka badan 1200GS, heerka xooggana waxaa la kordhin karaa oo keliya 63.16%, soo kabashada birtana si weyn ayaa loo dhimay.
Macaamiishu waxay u baahan yihiin in qalabkan loo doorto xoogga birta ee la doortay, waxayna baaraan habka loo shido warshadda si loo gaaro in ka badan 66% shuruudaha tayada xoogga.
Tijaabada, kala-soocidda birlabta xoogga leh 1200GS ayaa loo isticmaalay darajooyinka TFE. TFE-ga xoogga leh ee ka dhashay wuxuu ahaa 61.83%, badeecada TFE-na waxay ahayd 63.45% xoogga la helay.2.55% laga bilaabo 66%.
Qaado xoogga asalka ah iyada oo loo marayo 160 mesh iyo 200 mesh screening si loo falanqeeyo xaaladda birta.
Shaxda hal natiijada falanqaynta cabbirka walxaha macdanta asalka ah
Falanqaynta cabbirka walxaha, waxaa la ogaaday in ay jiraan nooleyaal badan oo ku jira birta aasaasiga ah, hoobiyahana loo baahan yahay ilaa -160, macdanta birta iyo xididdada ayaa gaari kara kala-goynta monomer ku filan. Qaado macdanta sifeynta birta asalka ah ilaa -160, siday u kala horreeyaan, xulashada magnetic 1200GS iyo JCTN refine dessesment magnetic selection magnition qaybaha magnetic 3000 GS ayaa la barbar dhigayaa, natiijooyinka baaritaankana waa sidan soo socota:
Natiijooyinka isbarbardhigga xulashada magnetic-ka ee miinada laba-mitir ah
| Xaaladaha tijaabada ah | Magaca alaabta | Wax soo saar% | Dhadhanka TFE% | Heerka soo kabashada TFE% |
| -160 Mesh Kala-soocidda Birlabta Caadiga ah1200Gs | Xoogga birta | 88.45 | 65.32 | 94.14 |
| Daboolnimo | 11.55 | 31.17 | 5.86 | |
| Macdanta asalka ah | 100.00 | 61.38 | 100.00 | |
| -160 Mesh JCTN-3000Gs | Xoogga birta | 88.19 | 68.60 | 97.67 |
| Daboolnimo | 11.81 | 12.23 | 2.33 | |
| Macdanta asalka ah | 100.00 | 61.94 | 100.00 |
Dhumucda asalka ah ee shiidi karta ilaa -160 waa 65.32% TFE-ga xooggan. JCTN waxaa laga soo xulay 68.60%, heerka darajada iyo soo kabashadana waa 3.28% iyo 3.50%, siday u kala horreeyaan.
Iyada oo laga jawaabayo dabeecadda dahaarka fiican ee macdanta birlabta ee Sichuan, tijaabada la go'aamiyay - xulashada qallafsan - dib-u-shiidid qallafsan - JCTN Magnetic Magnetic Magnetic Process ayaa lagu dabaqaa wax soo saarka dhabta ah, hadda, warshadda qaybinta. Dhadhanka TFE ee ikhtiyaariga ah ee birlabta ah waa mid deggan oo ka sarreeya 68%, soo kabashadana waxay la mid tahay tilmaame tijaabo ah, iyo ammaanta sare ee macaamiisha.
