Description

Multistage screening mechanism of industrial silicon Technical Field The utility model relates to the field of screening mechanisms, in particular to an industrial silicon multi-stage screening mechanism. Background Industrial silicon, also called metallic silicon, is produced by drying and smelting silicon mud. Specifically, wet silicon mud is put into a special oven for drying and then transferred to an intermediate frequency furnace for smelting and impurity removal. The silicon mud is a low-temperature antioxidant, soft is common, the hand feeling is fine and smooth, the weight is light, the silicon mud is porous and strong in water absorption, dust is easily generated when the dried silicon is exposed in the air, and industrial silicon prepared by smelting in an intermediate frequency furnace has the characteristics of hardness and brittleness. In view of the different characteristics of silicon materials at different stages in the industrial silicon production process, there are many problems to be solved in the processes of drying, transferring, smelting, crushing and the like.
