Products Description

Metal silicon powder processing refers to the process of smelting out silicon blocks (25-80 mm), through a special process to break, and produce a specified particle size (usually 80-400 microns) range of silicon powder. The metal silicon powder used for the production of silicone and polysilicon must have the corresponding technical indicators, the key technical indicators of metal silicon powder: chemical composition, particle size, morphology, specific surface area, physical and chemical properties reflect the chemical reactivity of metal silicon powder.

There are many methods to make metal silicon powder with silicon block as raw material, among which the common ones are Raymond method, roll method, disc grinding method and impact spinning method. From the perspective of pulverizing principle, the first three are extrusion crushing, and the last one is impact crushing. The technical parameters of the silicon powder obtained by different milling methods are different in terms of microstructure, specific surface area, particle size distribution and surface oxidation, and the reactivity of metallic silicon powder is naturally different. Therefore, it is necessary to select a suitable silicon powder production process and equipment.

Vertical grinding metal silicon powder production process: silicon block after drying, broken into the vertical mill, the ground silicon powder is taken out by circulating air flow, collected by the collector, the received powder is screened by the vibrating screen, the coarse grain sieve returned to the mill, the fine grain sieve into the finished product bin. Most of the dusty gas discharged by the collector is recycled, and a small part of the dusty gas is directly discharged at high altitude. The main equipment of the process includes vertical grinding; A collector; Centrifugal fan; The vibrating screen.
