[0002] Tin oxide SnO2 is an inorganic substance, has white, light yellow or light gray tetragonal, hexagonal or rhombic system powder form. 3 Tin oxide powder plays a vital role in the experiment of large-scale tin oxide electrode for optical glass melting, and the tin oxide electrode is a high-temperature conductive ceramic heating material made of tin oxide powder through various production processes.

[0003] Tin oxide powder needs to be screened and impurity-removed for pretreatment before preparation or application, and these impurities may affect the uniformity and stability of the powder. Through screening, the particle size distribution of the powder can meet the specific requirements, providing better conditions for subsequent application.

Since the powder lumps are also composed of tin oxide powder, directly pouring them out will inevitably cause material waste. Even if they are not poured out, collecting and processing them manually is also very time-consuming and laborious. UTILITY MODEL CONTENTS
