Metal silicon appearance
The appearance of metallic silicon is usually silver-gray crystalline, with a relatively smooth surface without roughness or bulges caused by oxidation products.
Metal silicon powder
Metal silicon powder is a kind of powdered metallic silicon, which has the same composition as bulk metallic silicon.
The appearance of metallic silicon powder is silver gray or dark gray powder with metallic luster.
The particle size of metallic silicon powder is usually between 10-100 microns. During the processing, due to different production processes and requirements, metal silicon powder of different particle sizes may be produced. Generally speaking, the larger the mesh number, the finer the material particle size; the smaller the mesh number, the larger the material particle size.
Metal silicon powder processing
The particle size processing process of metallic silicon powder includes the following steps:
1. Crushing: Crush the selected ore into particle sizes suitable for further processing.
2. Screening: Screen the crushed stones to separate particles of different sizes for further crushing and processing. The screening process can use a screening machine to carry out screening and classify particles according to prescribed standards to achieve the expected quality requirements.
3. Crushing: Particles of different sizes are fed into the crusher for crushing. There are many types of pulverizers to choose from, such as ball mills, Raymond mills, and ring roller mills, each with its own advantages and disadvantages. Factors such as processing temperature and humidity need to be strictly controlled during the crushing process to ensure that the powder quality meets the expected requirements.
4. Drying: In order to ensure the dryness of the silicon powder, it needs to be dried. The drying process requires controlling parameters such as temperature and time to achieve the appropriate degree of drying.
5. Packaging: The dried silica powder can be packaged and stored. Packaging materials generally take the form of plastic bags, cardboard boxes, iron drums, etc. During the packaging process, attention must be paid to sealing and moisture-proof measures to ensure product quality.
