CEMENT CALCINED BAUXITE FOR CEMENT INDUSTRY
Kategori : Madencilik
|
Cement Grade Bauxite
Calcined bauxite used in high alumina or calcium aluminate cements range considerably in chemical composition. A high silica content hampers the rapid hardening property of the cement. This means the silica content must be controlled and a typical industry requirement is that the Al2O3:SiO2 ration is around 10:1. And the maximum acceptable amount of Fe2O3 allowed in the low iron oxide type may reach 3%, although it is commonly max. 2.5%.
Calcium aluminate cement, alumina cements or high alumina cements are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The product obtained after cooling is a hard mineral: calcium aluminate clinker.Crushed or screened, it is used as an aggregate. The composition and colour - ranging from the purest white to jet black - depends on the proportion of each raw material.
Ground into a fine powder, the clinker becomes calcium aluminate cement (CAC) which forms a paste when mixed with water. This has the ability to harden very quickly: it forms a rigid solid within 24 hours.
Application
1.Aluminium industry.
2.Precision casting.
3.Refractory industry.
4.Silicic acid aluminium firefibre
5.Mixed with magnesium oxide,it can be an nice bonding agent,especially for pouring entire steel teeming ladle lining
6.Manufacture bauxite cement,grinding abrasives.ceracmic industry,and chemical industry for making aluminium compounds
