Brief Description
85%-92%Dead burned magnesia is mainly made of natural magnesite ore with 46%content,which is calcined by high temperature kiln at about 1400℃-1800℃ .
94%-98%Dead burned magnesia is made of natural super-grade magnesite ore.It is made by light burning,fine grinding,pressing balls and calcining in ultra-high temperature oil shaft kiln.
