Kufotokozera Kwachidule

Bauxite ndi mchere wachilengedwe, wolimba kwambiri ndipo umapangidwa ndi aluminium oxide compounds(alumina), silica, iron oxides ndi titanium dioxide. Pafupifupi 70 peresenti ya padziko lonse lapansi yopangidwa ndi bauxite imayengedwa kudzera mu njira ya mankhwala a bayer kukhala aluminiyamu.

Kutengera mfundo yakuti bauxite clinker imakhala ndi matenthedwe ang'onoang'ono otenthetsera komanso kukana bwino kwa skid ndi katundu wosavala, itha kugwiritsidwa ntchito mu HFST (mankhwala olimbana kwambiri ndi pamwamba) kapena abrasion wosanjikiza wa asphalt osakaniza kuti alowe m'malo kapena pang'ono m'malo omwe alipo. Bauxite clinker imagawidwa m'mitundu isanu ndi umodzi molingana ndi zomwe zili mumankhwala osiyanasiyana. Kusankhidwa kwa bauxite clinker monga aggregate sikungowonjezera phindu lachuma, komanso kupititsa patsogolo kumamatira pakati pa aggregate ndi asphalt, omwe ali ndi khungu linalake. bauxite clinker yokhala ndi phula idawunikidwa pogwiritsa ntchito njira yotsatsira ya hydrostatic adsorption komanso chiphunzitso champhamvu champhamvu chapamwamba.

Zambiri zambiri

Bauxite ndi mchere wachilengedwe, wolimba kwambiri ndipo umapangidwa ndi aluminium oxide compounds(alumina), silica, iron oxides ndi titanium dioxide. Pafupifupi 70 peresenti ya padziko lonse lapansi yopangidwa ndi bauxite imayengedwa kudzera mu njira ya mankhwala a bayer kukhala aluminiyamu.

Bauxite ndiye zopangira zoyenera kupanga alumina. Kupatula zigawo zikuluzikulu za aluminiyamu ndi silicon, bauxite nthawi zambiri imaphatikizidwa ndi zinthu zambiri zamtengo wapatali monga gallium (Ga), titaniyamu(Ti), scandium(Sc), ndi lithiamu(Li) . kupanga nthawi zambiri kumaphatikizapo zinthu zambiri zamtengo wapatali, zomwe zimawapangitsa kukhala gwero la polymetallic. Kubwezeretsanso zinthu zofunikazi kumatha kukulitsa luso lopanga alumina pomwe kumachepetsa zovuta zamafakitale komanso kukhudzidwa kwachilengedwe. Kafukufukuyu akupereka kuwunika kozama kwaukadaulo womwe ulipo womwe umagwiritsidwa ntchito kubweza zinthu zamtengo wapatali kuchokera ku zotsalira za bauxite ndikuzungulira mowa womwe wagwiritsidwa ntchito kuti zidziwitse kagwiritsidwe ntchito kake ka zotsalira za bauxite monga gwero osati kungotaya zinyalala. Kuyerekeza zomwe zilipo kale zikuwonetsa kuti njira yophatikizira yobwezeretsanso zinthu zamtengo wapatali ndikuchepetsa kutulutsa zinyalala ndizopindulitsa.
