I runga i te meka he iti te whakahaerenga waiariki o te bauxite clinker me te pai ake o te paheketanga o te paheketanga me nga rawa whakakakahu, ka taea te whakamahi i roto i te HFST (te maimoatanga mata o te waku teitei) te paparanga abrasion ranei o te ranunga uku hei whakakapi, hei whakakapi ranei i tetahi waahanga o te whakahiato o naianei.Ka whakarōpūhia te kirikiri Bauxite ki nga momo e ono e ai ki nga momo momo matū o roto.Ko te kowhiringa o te klinker bauxite hei whakahiato ehara i te mea mo te uara ohaoha anake, engari mo te whakapai ake i te piri i waenga i te aggregate me te uku, he matapo tera. I arotakehia e tenei rangahau nga ahuatanga o nga momo momo clinker bauxite.Ko te piri o nga momo rereke I arotakea te clinker bauxite me te parapara ma te whakakorikori i te tikanga whakamaaramatanga hydrostatic me te ariā o te hiko korekore o te mata. I arotakea te paanga o nga tawhā ahuatanga o te clinker bauxite ki te apitihanga ma te wetewete entropy hononga hina.

Nga korero taipitopito

Ko te Bauxite te mea tino pai mo te hanga alumina.I tua atu i nga waahanga tuatahi o te konumohe me te silicon, he maha nga wa e honoa ana te bauxite me te maha o nga mea utu nui penei i te gallium (Ga), titanium (Ti), scandium (Sc), me te lithium (Li). Ko te tikanga he maha nga huānga utu nui i roto i te whakaputanga, ka waiho hei puna pea mo te polymetallic.Ko te whakaoranga o enei waahanga nui ka taea te whakanui ake i te pai o te mahi whakangao alumina i te wa e whakaitihia ana te taunahatanga ahumahi me te paanga o te taiao.Ko tenei rangahau e whakaatu ana i te tino wetewete o nga hangarau o naianei e whakamahia ana hei whakaora i nga huānga nui mai i te toenga o te bauxite me te toha i te waipiro pau hei whakamaarama mo te whanuitanga o te whakamahinga o te toenga bauxite hei rauemi, kaua hei para.Ko te whakatairite o nga ahuatanga o naianei e whakaatu ana he pai te mahi whakakotahi mo te whakaora huānga nui me te whakahekenga para.
