White monoclinic crystalline or amorphous powder. Non-toxic, non-odorous and stable. The relative density is 2.16. Slightly soluble in water, the aqueous solution is weakly alkaline and has a solubility in water of 0.02% (15 ° C). Soluble in acid and ammonium salt solutions. When calcined, it is easily decomposed into magnesium oxide and carbon dioxide. In case of dilute acid, it will release carbon dioxide. Generally soluble in water. It is easy to react with water when heated (when hard water softens) to form magnesium hydroxide (because magnesium hydroxide is more difficult to dissolve than magnesium carbonate).
Special drying equipment for magnesium carbonate Working principle:
The wet material is continuously fed from the feeder to the first layer of the drying tray on the upper part of the dryer, and the raking arm with the raking leaves is rotated to make the raking arm make a rotary motion so that the rakes continuously pluck the material. The material flows along the exponential spiral through the surface of the drying tray, the material on the small drying tray is transferred to the outer edge, and falls to the outer edge of the large drying tray below the outer edge. On the large dry tray, the material moves inward and falls from the middle. The material is dropped into a small dry tray as follows. The size of the drying tray is alternately arranged up and down, and the material is continuously flowed through the entire dryer. A heating medium is introduced into the hollow drying tray. The heating medium is in the form of saturated steam, hot water and heat transfer oil. The heating medium enters from one end of the drying tray and is led out from the other end. The dried material falls from the last layer of the drying tray to the bottom layer of the casing and is finally transferred to the discharge port by the rakes. The moisture fraction escapes from the material and is discharged by the moisture discharge port provided on the top cover, and the moisture of the vacuum type tray dryer is discharged by the vacuum pump port provided on the top cover. The dry material discharged from the bottom layer can be directly packaged. By adding fin heater, solvent recovery condenser, bag filter, dry material back mixing mechanism, induced draft fan and other auxiliary machines, it can improve its drying production capacity, dry paste and heat sensitive materials, which can be easily recycled. Solvent and can perform pyrolysis and reaction operations.
Special drying equipment for magnesium carbonate Main features:
1. The first is that it can run continuously and efficiently.
2. Secondly, the disc dryer consumes less when it is working, and its noise is also small.
3. The materials dried by the disc dryer are uniformly heated and the drying time is not long.
4. Environmental protection.
5, reduce manual operations, the operation is closely operated.
6. The drying medium can be used without the help of a large amount of coal, and the steam generated by the waste heat boiler can be directly used.
