Technical Field

[0001] This utility model relates to the field of preparing calcium fluoride from fluorite concentrate, and in particular to an efficient apparatus for classifying and preparing calcium fluoride from fluorite concentrate. Background Technology

[0002] Fluorite concentrate is a high-purity calcium fluoride product obtained by processing and purifying natural fluorite ore through multiple processes such as crushing, grinding, flotation, dehydration, and drying. It is the most core and fundamental strategic raw material in the fluorochemical industry chain and is widely used in key fields such as refrigerants, fluoropolymers, fluorinated electronic chemicals, and new energy materials.
