Description

Technical Field

[0001] The utility model relates to the technical field of polysilicon crushing, in particular to an automatic polysilicon crushing device. Background Art

[0002] Polycrystalline silicon is a form of elemental silicon. When molten silicon solidifies under supercooling conditions, silicon atoms arrange themselves into numerous nuclei in a diamond lattice. When these nuclei grow into grains with varying crystal orientations, these grains combine to form polycrystalline silicon. After crushing, polycrystalline silicon can be made into granular materials, typically classified into several grades to suit different solar cell production processes and operational requirements. Crushed polycrystalline silicon particles are easier to purify and grow, thereby improving the photovoltaic conversion efficiency of solar cells.
