Metal silicon powder production process and device

The invention relates to a metal silicon powder production process. The metal silicon powder production process includes: silicon blocks are primarily crushed by a hammer type crusher, the crushed silicon blocks enter a crushed material bin through a first bucket type elevator, and the crushed silicon blocks are pulverized in a vertical type pulverizer into pulverized materials; the mixed coarse powder of the pulverized materials is fed into a square swing screen through a second bucket type elevator and screened, the finished powder screened to the lower portion of the square swing screen is stored in a finished product bin, and the coarse powder remained on the square swing screen is returned to the vertical type pulverizer through a third bucket type elevator for secondary pulverizing; the fine powder of the pulverized materials are collected by a cloth bag dust collector to enter a fine powder bin, and fine powder is packed for sale. A metal silicon powder production device comprises the hammer type crusher, the first bucket type elevator, the vertical type pulverizer, a second bucket elevator, the cloth bag dust collector, the third bucket type elevator and the square swing screen.
