Nhazi nke bauxite

Bauxite, nke a makwaara dị ka bauxite ma ọ bụ bauxite, bụ nke aluminom oxide mejupụtara na nke nwere adịghị ọcha. Bauxite nwere ngwakọta dị mgbagwoju anya nke ukwuu yana ọ bụ okwu n'ozuzu maka ụdị alumina hydrous dị iche iche nwere mmalite ala dị iche iche.

Dị ka ojiji nke bauxite si kwuo, a na-ekewa ya na ọkwa metallurgical, ọkwa kemịkalụ, ọkwa refractory, grader grade, cement grade, wdg. A na-eji ihe ndị na-emepụta ihe na-emepụta ihe, ụdị bauxite a na-akpọ refractory grade alumina. Bauxite clinker nwere oke kwesịrị ekwesị nke AL2O3/Fe2O3 na AL2O3/SiO2 na-eji agbaze alumina.

1. Igwe ọkụ na-ekpo ọkụ dị elu, nkwụsi ike okpomọkụ siri ike, na enweghị mgbawa. Aluminom mullite ájá bụ ngwaahịa sitere na aluminom na silicon. Mgbe calcination gasịrị, nkwụghachi azụ ya na nkwụsi ike na-ekpo ọkụ dị nnọọ ukwuu karịa nke ájá quartz nwere usoro kristal nke nwere otu silicon kristal. Ọ naghị adị mfe wet site na mmiri mmiri metal na-etolite a ala gbazee, nke nwere ike imeri Quartz ájá nwere nnukwu thermal mgbasa ọnụ ọgụgụ na-adịghị mma mkpụrụ n'oge condensation, na-akpata adịghị ike dị ka obere nkedo ziri ezi na ájá arapara n'ahụ.

2. dị iche iche urughuru gradation, mma breathability. A na-akụ ájá nke ụlọ ọrụ Raymond ma gwakọta ya dị ka gradation a kapịrị ọnụ n'oge mmepụta iji meziwanye ikike ikuku nke agba. Tụkwasị na nke ahụ, ngwaahịa ndị a na-emepụta site na igwe igwe, ihe nkedo ájá nke Raymond na-edozi na-achịkwa nke ọma, na oke nke bauxite clinker bụ nke sayensị.

3. Ihe mkpuchi ahụ nwere njikọ dị elu, ike dị elu na nkwụsị dị mfe. Ihe mkpuchi refractory dị iche iche na-eji ngwaahịa aluminom-silicon clinker, furu efu bauxite clinker ezigbo ntụ ntụ, dịka gradations dị iche iche sitere n'ime. Nchikota site na mma na nke na-adighi nma na-ebute nchikota di elu n'etiti mkpuchi; ka ọ na-abawanye ike mkpuchi na mgbochi mbuze iji gbochie nsogbu ndị dị ka ọdịda, ọ dịkwa mfe ịkwatu. Na bauxite mullite bụ ihe na-anọpụ iche, a pụkwara iji bauxite clinker mee ihe dị ka ma acid na alkali binders.
