Technical Field

[0001] The utility model relates to the technical field of sodium aluminate processing, and more specifically, to a mixer for sodium aluminate processing. Background Art

[0002] Sodium aluminate is a white particle that is hygroscopic and very soluble in water, insoluble in ethanol, and its aqueous solution is strongly alkaline. The sintering method can be used to prepare sodium aluminate. The specific steps are: finely mix bauxite, soda ash and limestone, sinter at high temperature, leaching the clinker with water, removing silicon from the leached sodium aluminate solution, obtaining a refined sodium aluminate solution, and evaporating to dryness to obtain the finished sodium aluminate product.
