Basic magnesium carbonate flash dryer

Jun 19, 2024

Case introduction: Basic magnesium carbonate flash dryer is a new type of continuous drying equipment that integrates drying, crushing and screening. The drying time of basic magnesium carbonate wet material in the drying tower is only 5-8 seconds, and the water evaporates instantly.

Basic magnesium carbonate is a loose white powder or a light brittle substance. It is almost insoluble in water, but causes a mild alkaline reaction in water. Insoluble in ethanol, can be dissolved by dilute acid and foamed. It doesn't normally break down. Mainly used as a filler and reinforcing agent for transparent or light-colored rubber products, the reinforcing effect is better than calcium carbonate and clay. Its refractive index is similar to that of natural rubber, so it is suitable for manufacturing transparent or translucent products, and can enhance the wear resistance, bending resistance and tensile strength of rubber. It can also be used as an additive in paints, graphite and coatings, and in industries such as toothpaste, medicine and cosmetics.

Basic magnesium carbonate flash dryer is a set of drying, crushing, screening in one of the new continuous drying equipment, basic magnesium carbonate wet material in the drying tower drying time is only 5-8 seconds, the water evaporates instantly, the quality of the dried product and drying temperature, wind speed, air volume, crushing speed has a great relationship. The hot air enters the annular gap at the bottom of the drying chamber in the tangential direction from the inlet pipe and rises spirally. At the same time, the material is quantitatively added into the tower by the feeder and has full heat exchange with the hot air. The large and wet material is mechanically broken under the action of the agitator, and the material with low wet content and small particle size rises with the rotating air flow and is transported to the separator for gas-solid separation .The finished product is collected and packaged, while the exhaust gas is treated by a dust removal device and emptied.

Basic magnesium carbonate flash dryer equipment features:
1. High gas velocity in the drying room, short residence time of materials, effectively prevent the material from sticking to the wall and the deterioration of heat-sensitive materials, and can be dried into uniform powder products at one time, eliminating the grinding, screening and other processes.
2. The drying chamber is equipped with grading ring and swirl sheet, and the fineness and final moisture of the material can be adjusted. The special air distribution device reduces the resistance of the equipment and effectively improves the drying uniformity of the material.
3. The bottom of the dryer is equipped with a special cooling device and air pressure seal to avoid deterioration of the material in the bottom high temperature area.
4. It can effectively control the final moisture and fineness, and ensure the moisture content and fineness of the product are uniform through the adjustment of the feeding, hot air temperature and classifier.

Flash dryer is a new type of continuous drying equipment which integrates drying, crushing and screening. It is especially suitable for drying filter cake, paste and mud paste. The drying time of the wet material in the drying tower is only 5-8 seconds, and the water evaporates instantaneously. The quality of the dried product has a lot to do with the drying temperature, wind speed, air volume and crushing speed.
