High Alumina Refractory Binder Supplier



We are Leading Manufacture & Suppliers of Calcium Alumina Cement, High Alumina Refractory Cement and High Alumina Refractory Binder.

 

Calcium Aluminate cement / High Alumina Cement is produced by preparing raw meal consisting of applicable bauxite and limestone, calcining the raw meal in rotary klin and grinding the clinker, which contains Al2O3 50-60%. it was called bauxite cement for a time and also called” refractory cement” based on its main usage. The name ”aluminate cement (High Alumina Cement)”is specified by the national standard now.
