Definitions
- Purification of the classified polysilicon fracture can be easily and completely removed.
- all surfaces of the units that come into contact with polysilicon in the individual processing steps from a non-low-contamination steel, more preferably made of a low-alloy steel.
- the parts in contact with the product were the chisels, the shells forming the base of the pre-shredder, the crushers and linings of the crusher, all conveyors and the liners in the mechanical sieves and in the optopneumatic sorting modules.
