Izindaba Zemboni

I-10-inch cutter suction dredger ingesinye sezixazululo ezisetshenziswa kakhulu zokudonsa amaphrojekthi kumaphrojekthi amancane okususa intlenge asezingeni eliphakathi. Ihlanganisa ukusika, ukumunca, kanye nokuthuthwa kwamanzi okudonsa amanzi kube yisistimu eyodwa edidiyelwe, okuyenza ilungele ukugcinwa komfula, ukuhlanza amachibi, ukubuyiselwa kogu, nokuphathwa kwemisila yezimayini. Lesi sihloko sinikeza ukucutshungulwa okuphelele kokuthi lesi sixhobo sisebenza kanjani, izingxenye zalo eziyinhloko, izinzuzo zokusebenza, izinhlelo zokusebenza zomhlaba wangempela, izidingo zokunakekelwa, nokucatshangelwa kokukhetha.

Emkhakheni wezinjini zasolwandle, i-Weichai ne-Cummins bangabakhiqizi ababili abanevolumu enkulu yokufaka nesabelo semakethe. Kodwa kufanele siyikhethe kanjani injini yasolwandle?

I-Small Shallow-Water Cutter Suction Dredger isibe ngesinye sezixazululo esisebenziseka kalula nesingabizi kakhulu semisebenzi yesimanje yokudonsa emifuleni, emachibini, emachibini nasezindaweni ezingashoni ngasogwini. Lesi sihloko sihlola izimiso zayo zokusebenza, izinzuzo zobuchwepheshe, izimo zohlelo lokusebenza, izidingo zokunakekelwa, kanye nesiqondiso sokukhetha. Yakhelwe ukusiza abanikazi bephrojekthi, osonkontileka, nezinkampani zobunjiniyela ukuthi baqonde ukuthi le mishini ixazulula kanjani izinselelo ezijwayelekile zokudonsa amanzi njengokujula okuphansi kwamanzi, ukuvinjwa kwenhlabathi, ukufinyeleleka okulinganiselwe, nokusebenza kahle.

Imisebenzi yezimayini zegolide ivamise ukubhekana nenselelo eyodwa enkulu: insimbi eboshwe ngodaka nezinto ezinodaka ezinciphisa ukusebenza kahle kokululama futhi zikhuphule izindleko zokucubungula. I-Gold Trommel Scrubber iklanyelwe ngokukhethekile ukudiliza izinto ezihlanganisiwe, isuse ukungcoliswa kobumba, futhi ilungiselele insimbi yezinhlelo zokubuyisela ezansi nomfula.

Imisebenzi yezimayini zegolide ihlale ibhekana nezinselele ezinjengokulahlekelwa kwegolide elicolekile, ukusetshenziswa kwamanzi okuphezulu, ukungasebenzi kahle kokutholwa kwegolide, kanye nokwenyuka kwezindleko zokusebenza. I-Alluvial Gold Pulsating Sluice yakhelwe ukunqoba lezi zinkinga ngokuhlanganisa izimiso zokugxilisa amandla adonsela phansi nobuchwepheshe bokugeleza kwamanzi obuphehlayo.

Imboni yezimayini ngokuqhubekayo ifuna ubuchwepheshe obukhulisa ukubuyiswa kwezimbiwa ngesikhathi inciphisa izindleko zokusebenza kanye nomthelela emvelweni. Phakathi kwezixazululo ezisebenza kahle kakhulu zokuhlukanisa amandla adonsela phansi ezitholakalayo namuhla, i-Nelson Centrifugal Concentrator isibe yinketho ekhethwayo yokuthola igolide elicolekileyo namaminerali asindayo avela kuma-slurries ensimbi.
