Pan American Silver (TSX: PAAS) yakazivisa kuti maoparesheni atanga pamigodhi yayo yeDolores neLa Colorada muMexico, zvichitevera kutangwazve kwayo Shahuindo, La Arena, San Vicente uye Manantial Espejo mashandiro, kwakatangwa muna Chivabvu.

Migodhi iyi iri kutanga kushanda yakadzikira kuti igadzirise mapuroteni matsva mukupindura Covid-19, Pan American akadaro.

Pan American parizvino yakamirira mvumo yekutonga kuti itangezve mashandiro eHuaron neMorococha muPeru.

Wechipiri pakukura pasirese mugadziri wesirivheri akamisa basa rakajairwa kumigodhi yake muMexico, Peru, Argentina neBolivia munaKurume kuti vatevedzere matanho ekuvharirwa munyika.

Iyo Timmins West neBell Creek migodhi muCanada yakaramba ichishanda pa90%.

"Tiri kuenderera mberi nemaitiro akangwarira ekutangazve mashandiro, apo isu tinoshanda kudzoreredza huwandu hwakazara hwekugadzira pamashandiro edu tichichengetedza hutano nekuchengetedzeka kwevanhu vedu," CEO Michael Steinmann akadaro.

Pan American yakabvisa gwara rayo rekushanda ra2020 munaKurume 12, 2020, zvichipihwa kusagadzikana kwakabatana nedenda.

Midday Chipiri, Pan American stock yaive yadzika 6% paTSX. Iyo kambani ine C $ 8.1 bhiriyoni yemusika capitalization.

Ball Mill Liner Material Sarudzo

Yakasiyana yakapwanyika zvinhu, akasiyana ekushanda mamiriro anoda akasiyana zvinhu liner kuti aenderane. Zvakare, iyo yakakasharara yekukuya compartment uye yakanaka yekukuya compartment inoda akasiyana matinji.

H&G Michina inopa zvinotevera zvinhu kukanda yako bhora chigayo liner:

Manganese Steel

Iyo manganese yemukati meyakakwira manganese simbi bhora chigayo lining plate inowanzo 11-14%, uye iyo kabhoni yemukati inowanzo 0.90-1.50%, mazhinji ayo ari pamusoro pe1. Pamitoro yakaderera, kuoma kunogona kusvika HB300-400. Pakukwirisa mitoro, kuoma kunogona kusvika HB500-800. Zvichienderana nekutakura mutoro, kudzika kweiyo yakaomeswa layer inogona kusvika 10-20mm. Iyo yakaomeswa layer ine kuomarara kwakanyanya inogona kuramba kukanganisa uye kuderedza abrasive kupfeka. Yakakwira manganese simbi ine yakanakisa anti-kupfeka mashandiro pasi pemamiriro eiyo yakasimba kukanganisa abrasive kupfeka, saka inowanzoshandiswa munzvimbo dzisingapfeki dzemigodhi, zvekuvaka, simba rekupisa, uye zvimwe zvemichina. Pasi pemamiriro ekuderera kwemamiriro ezvinhu, yakakwira manganese simbi haigone kuita hunhu hwechigadzirwa nekuti basa rekuomesa mhedzisiro haisi pachena.
