Mutengo wemhangura unokwira kusvika kumakore maviri kumusoro

Mitengo yeramangwana remhangura yakawedzera neChipiri mushure mechibvumirano chehurongwa hukuru hwekusimudzira hupfumi muEurope, tarisiro nezvechirwere checovid-19 uye kushushikana kuri kuramba kuchiitika nezvedenda kubva kune mugadziri wepamusoro South America.

Mhangura yekuunza munaGunyana kutengeserana muNew York yakachinja maoko kuita $2.9750 paundi ($6,560 patani) mukutengeserana kwemasikati ekutanga, yakakwira 2% kubva pakagadziriswa Muvhuro.

Mitengo yeMhangura yeramangwana iri munzira yekuvharika kwepamusoro mumakore maviri uye ikozvino yakwira neinopfuura makumi mashanu muzana kubva kuCOVID-19 lows yakaitika munaKurume.

Mucheri wemhangura wepamusoro-soro weBHP akazivisa neChipiri kuti inotarisira kuburitsa kwayo mhangura kudonha nepakati pe5% ne14% mugore rayo rinotevera remari kupera-Chikumi 2021.

BHP, iyo ine chikamu-varidzi uye inoshanda Escondida muChile, mugodhi mukuru wemhangura pasi rose, yakati kudonha kuri kutarisirwa mukugadzirwa kwemhangura kunokonzerwa nekudzikira kwevashandi vayo zvine chekuita neCovid-19 zvirambidzo.

Iyo Melbourne-yakavakirwa kambani ikozvino inotarisira 2020-2021 kuburitsa mhangura iri pakati pe1.48m - 1.65m matani, pasi kubva pa1.72m matani akagadzirwa mugore rapfuura. 

Muchinyorwa chechangobva kuitika, Capital Economics inonongedza kuti mitengo yekubuda yakaderera zvakanyanya muChile, Peru neMexico, iyo pamwe chete inoita makumi mana neshanu muzana ekugadzirwa kwepasirese.

Kubuda kwave kumatanho ekupedzisira kuoneka muna 2017 panguva yekuramwa kwenguva refu kuEscondida, iyo pachayo inokonzera ingangoita 5% yekugadzirwa kwepasirese.

Kuwedzera kutengwa kweChinese

Data yecustom yakaburitswa svondo rapfuura yakaratidza kutengwa kwemhangura yeChina isina kuchekwa (anodes nemacathodes) muna Chikumi yakakwira zvinoshamisa makumi mashanu muzana kubva pamwedzi wapfuura kusvika pamatani 656,483 - yakazara 15% pamusoro perekodhi yepamwedzi yapfuura.

Mitoro yaChikumi yakapetwa kaviri yemwedzi mumwe chete gore rapfuura sezvo zvikamu zvezvivakwa uye zvekugadzira muChina, zvinokonzeresa inopfuura hafu yekudyiwa kwemhangura pasi rose, nekukurumidza kupora zvichitevera kudonha kweCovid-19.

Kupfuura hafu yekutanga ya2020, kunze kwenyika kwakasvika 2.84m matani - kumusoro 25% gore-pa-gore uye munzira yekurova zviri nyore rekodhi regore ra2018 rematani 5.3m. 

Kupinzwa kunze kwenyika kwemhangura yemhangura kwakadonha zvisingatarisirwi, zvichidzika kubva pa6% kusvika 1.69m matani kubva muna Chivabvu, asi zvichiri kukwira ne8.4% kubva munaChikumi gore rapfuura, nekuda kwekukanganiswa kwemigodhi muPeru, mutengesi wepamusoro weChina.

Chimwe chinoratidza kudiwa kuri pamusoro pekupa kuderera kwemitengo yekurapa nekukwenenzvera. TC/RCs dzinobhadharwa nevacheri vemigodhi kune vanonyungudutsa dzawira pasi kusvika pamakore masere, chiratidzo chemakwikwi pakati pevanonatsa kuti varipo vatarise.

Kwemwedzi mitanhatu yekutanga ye2020 inotengeswa kunze kwenyika inokwana 10.84 miriyoni matani, padanho rekupfuura rekodhi rekodhi rekodhi rekodha rekodha regore rapfuura remamiriyoni makumi maviri nemaviri ematani.  

Hedge fund mabhuru

Commodity Futures Trading Commission data inoratidza hedge fund yekumisikidza mumusika wemhangura pakunyanya kusimba kwayo mumakore maviri.

Vafungidziri vakakura senge hedge funds vakavaka nzvimbo refu (mabheti kuti mhangura ichatengesa pamwero wepamusoro mune ramangwana) kune pre-denda mazinga uye panguva imwe chete akacheka shorts (mabheti kuti mhangura inogona kutengwa zvakare nemutengo wakaderera mukati. ramangwana).

Kubva Chipiri svondo rapfuura, mambure emari yaive yakabatana kureba kwezvibvumirano makumi mana nemazana matatu nemazana matatu, zvakakwira zvinoda kusvika 30% kubva svondo rapfuura uye kutaura kwakasimba kwekunzwa kubva munaJune 2018.

Sei spider bushing yakakosha?

Iyo Spider bushing ine hourglass chimiro uye nekudaro ine yakanyatso kujeka clearance. Kana dandemutande richinge risisatsigire shaft huru, pasi pegomba guru rinoshandisa simba rakawanda pane eccentric bushing yemukati. Kana spider bushing ikasachengetwa, zvinotevera zvinetso zvichaitika:

1. Yakatsva mukati nekunze eccentric bushing;
2. Saizi huru shaft;
3. Yakakuvadzwa nhanho mabhengi;
4. Yakakuvadzwa nzvimbo yebhawa;
5. Yakakuvadzwa main shaft uye shaft sleeve.

Mushoko rimwe chete, kusachengeta chinhu ichi kunokonzeresa kukuvadzwa kwakanyanya kune zvemukati mekiniki zvikamu zvekoni yako crusher.

Nzira yekuyera sei spider bushing saizi?

Kana iwe uchida kutenga spider bushings kubva kwatiri, unogona kutitumira mifananidzo yako kana chikamu chikamu. Kana iwe usina kudhirowa, rega tikutungamirire kuti ungayera sei cone crusher spider bushing mifananidzo.

• Kuda kuyera dhayamita rekunze
• Kuda kuyera dhayamita yemukati
• Inoda kuyera marefu maviri
• Kuda kuyera maburi ekuisa

Kana iwe uine chero mhando dzecone crusher spider bushings kubvunza, ndapota titumire madhirowa ako kana chikamu nhamba kuti titarise.
