High Purity Dead Burned Magnesia
High Purity DBM: The top group of high purity DBM grades with 96-97.5% MgO is based on finely selected super grade-A Magnesia ores and other ores being beneficiated by flotation process. Caustic calcination is done in various types of kilns, depending on the size of raw material feed, followed by fine milling and double step briquetting. The final sintering happens in ultra-high temperature oil or gas fired modern shaft kilns at temperatures of over 2200°C. This top grade DBM is worldwide well accepted and used for the production of high duty class refractory.
