Description

Technical Field

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

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

[0003] When processing sodium aluminate, bauxite, soda ash and limestone need to be finely mixed, so the three raw materials need to be ground. When using the common grinding device for sodium aluminate processing, in order to improve the grinding efficiency and prevent the blockage of grinding and feeding due to large raw material particles, the raw materials are generally crushed by a crushing mechanism. The raw materials cannot enter the grinding device during the crushing process and can only be fed after crushing. This results in a time interval between the crushing and grinding of the raw materials, which will affect the efficiency of raw material grinding and further affect the processing efficiency of sodium aluminate.
