Problems solved by technology

[0002] Alkaline chlorination of rare earth concentrates requires high decomposition rate and yield, while the traditional eddy current electric heating alkaline hydrolysis tank generally directly raises the reaction temperature to 150 degrees, which is particularly easy to cause paste or overflow at high temperature, and the product It is easy to change the price level, and the slurry will seriously corrode the alkaline hydrolysis tank after the pot is pasted or overflowed
In addition, the traditional alkaline hydrolysis tank generally uses a one-layer stirring paddle. As the reaction temperature rises and the water evaporates, the slurry becomes thicker and thicker, which is easy to cause paste.
