[0002] Silica powder ore refers to natural mineral raw materials rich in silicon dioxide, which is the initial material for producing silica powder. Before being processed into silica powder, the ore usually needs to go through multiple pretreatment and refining steps to remove impurities and obtain silicon raw materials that meet the requirements. In the production process of silica powder ore, drying is a key step to reduce the moisture in the material for subsequent processing, such as grinding, grading, etc.

[0003] At present, when drying the material to be dried in the process of silicon micropowder production, the material to be dried is placed in a drying box for drying. A large amount of material to be dried is concentrated and mostly falls on the same landing point, which makes the drying effect of the material to be dried uneven and the drying efficiency is low. Based on this, a silicon micropowder ore production drying device is proposed. Utility Model Content
