What are the methods for producing metallic silicon powder from silicon blocks?
There are many methods for producing metallic silicon powder from silicon blocks as raw materials, among which the common ones are the Raymond method, the counter-roller method, the disc grinding method and the punching and spinning method.
From the perspective of the powder making principle, the first three are extrusion and crushing, and the latter is It's impact crushing.
The technical parameters of metal silicon powder obtained by different powdering methods are different in terms of microstructure, specific surface area, particle size distribution and surface oxidation, and the reactivity of metal silicon powder is naturally different.
Therefore, it is necessary to select appropriate metal silicon powder production processes and equipment.
