crushing technology of silicon metal

US20090114748A1

Reproducible crushing along with such low metal contamination that subsequent cleaning of the crushed polysilicon is not necessary are both obtained. Polysilicon is crushed with a minimum of manual and machine crushing steps by utilizing a large diameter roll crusher, the circumferential crushing surface of which is formed of a plurality of reversibly mounted, close fitting hard metal plates.
