AI Technical Summary
The calcination quality of products from existing magnesium oxide powder calcining furnaces is unstable, making it difficult to meet the activity requirements of building material-grade magnesium oxide powder. In particular, the color change time of the citric acid method is difficult to control within 40s to 350s.
The design combines a suspension agglomeration unit and a conditioning unit. Through high-temperature cyclone separation, suspension agglomeration and conditioning treatment, the residence time of materials in the furnace and the gas-solid contact surface are increased, and the activity of magnesium oxide powder is controlled to ensure that it is adjustable and controllable within 40s~350s.
The activity of magnesium oxide powder is stabilized, meeting the quality requirements of building material grade magnesium oxide powder. The color change time of citric acid method is adjustable, and the active MgO mass fraction of the produced magnesium oxide powder is 70%~40%.
