Maro badan oo shaashad caag ah oo loogu talagalay macdanta birta ee Australia. Cross-tensioned 305 × 610mm, anti-clogging RIOLATEX qaacidada waxay socotaa 40% ka dheer PU. Reglin & Eurotech waafaqi. Codso qiimaha jumlada.
Waxaan ahay Agaasimaha Ganacsiga Dibadda ee Rio Minerals. 21 sano ee macdanta xidhashada ilaalinta. Waa kuwan waxa aan ka bartay suuqa baadhista ee Australiya - iyo sababta ay muraayadaheena caagga ah uga duwan yihiin.
Western Australia waxay soo saartaa in ka badan 900 milyan oo tan oo macdanta birta ah sannadkii. Taasi tiro maaha - taasi waa riyo baadhiseed. Hematite-qoyaanka sareeyo iyo macdanta goethite waxay xidhaan daloolada shaashadaha saacado gudahood, ma aha maalmo. Xiritaanka kasta oo aan qorshaysnayn ee shaashadda gariirku wuxuu ku kacayaa Tier-1 macdanta AUD 120,000-180,000 ee wax soo saarka lumay. Waxaan dhex maray warshad ku filan Pilbara si aan u ogaado muuqaalka wejiga kormeeraha dayactirka marka uu arko ku dhejinta guddi-polyurethane oo cusub.
Taasi waa sababta dhabta ah ee aan u horumarinay maro badan oo shaashadda caag ah - ma aha sida wax soo saarka guud, laakiin sida jawaabta tooska ah ee loolanka baarista qoyan ee birta. Qalabkayaga caagga ah ee dareeraha ah ee RIOLATEX wuxuu ka kooban yahay in ka badan 95% caag dabiici ah, taasoo siinaya isku-dhafka barti ee 2.3 × ka sarreeya heerka PU. Marka qayb ay isku daydo in ay isku dhufato daloolka, caagku wuu dabacsan yahay oo ka soo saaraa. Is-nadiifinta. Dadban. Ma jiro waqti dhimis
Goobaha miinada ee ku shaqeeya marada caagga ah ee ka-hortagga xiritaanka ee codsiyada macdanta birta - gaar ahaan Marra Mamba iyo Channel Iron Deposit (CID) macdanta - farqigaani wuxuu u tarjumayaa baarista hagaajinta wakhtiga aan ku cabbirnay 34-41% marka loo eego qaybaha OEM polyurethane. Xisaabtu waa sahlan tahay. Jeedin yari waxa ay ka dhigan tahay in yar oo joogsiga sagxada muraayadda, iyo joogsiyo yar oo ka dhigan tan in badan oo geedka dhex mara.
Taladayda 21 sano ka dib: haddii aad ku shaqaynayso shaashado qoyan macdanta birta, tag 40A xeebta leh dhumucdiisuna tahay 40mm iyo qaab dalool oo go'an. Qalafsanaanta hoose waxay ku siinaysaa dabacsanaanta aad u baahan tahay si aad is-nadiifinta, iyo nashqadaysan godadku wuxuu gacanta ku hayaa ganaaxyada macdanta CID si ka fiican godadka labajibbaaran. Waxa aan ku arkay 60A PU panels-ka ugu dambeeyay ee 3:1 isla sagxaddii.

3. Faa'iidada Magnetite - Wareegga Baarista Fiican
Caqabadda: Xoogayayaasha Magnetite ee gobolka Dhexe-Galbeed waxay ku shaqeeyaan 24/7 oo leh dheecaan silica-hodan leh. Inta jeer ee beddelka marada shaashadda waxay si toos ah u saamaysaa soo kabashada fasalka.
Xalkayaga: 50A xeebta, 2mm dalool labajibbaaran oo leh dhumucdiisuna tahay 38mm - oo loo habeeyay soocidda dharka hoose.
Natiijada Goobta: Hawlgalka joogtada ah ee 19-usbuuc ee warshad magnetite ee Geraldton, ilaalinta ± 0.15mm weecasho-dhibcaha. PU oo u dhiganta waxa loo leexiyay ±0.4mm usbuuca 6.

Su'aalaha Inta Badan La Isweydiiyo
S: Maro muraayadaha caagga ah ee isdhaafsan miyay ku habboon yihiin muraayadda muraayadda Metso/Ludowici ee jirta iyada oo aan wax laga beddelin?
Haa - 100%. Dabaqyadayada 305×610mm ee iskutallaabta isdhaafsan waxay isticmaalaan qaabka 4-bolt gees ka gees ee caadiga ah ee ay isticmaasho Metso, Ludowici, Schenck, iyo Eurotech decks Australia. Xarumo bolt oo isku mid ah, muuqaal tareen oo isku mid ah, qeexid xoog leh oo isku mid ah (55-65 Nm). Waxaan dhameystirnay in ka badan 40 dib-u-habeeynta shaashadda ee Australia oo aan waligeen u baahnayn inaan wax ka beddelno sagxadda. Haddii aadan hubin nooca shaashadda, iimayl noogu soo dir lambarkaaga taxanaha ah, aniguna shaqsiyan ayaan xaqiijin doonaa ku-habboonaanta ka hor intaanan dhoofin.
S: Waa maxay wakhtiga aad hogaaminayso amarada badan ee Perth ama Port Hedland?
Waqtiga caadiga ah ee ledhku waa 14-18 maalmood warshad-ilaa-Fremantle si loo dalbado ilaa 500 panels. Dalabka badan (500+ panels), ogow 21-25 maalmood. Waxaan ku haynaa kayd kayd ah oo ah 305 × 610mm panels gudaha 40A/60A iyo daldaloolada caadiga ah (3mm slotted, 6mm square, 50mm square) bakhaarkeena Perth 3PL - kuwani waxay u soo rari karaan goobta 48 saacadood gudahood. Sicir bararku wuxuu ka yimaadaa 50 qaybood, oo leh qiimo dhimis heerar ah oo ah 200 iyo 500 unug.
Sidoo kale Baadh Xadka Ilaalinta Xidhashada Dhamaystiran
Dharka shaashaddaadu waxay la shaqeeyaan qaybaha kale ee muhiimka ah ee xirashada wareegga wareegga macdanta. Buuxi nidaamkaaga ilaalinta shaashadda-ka-tuubada:
