Scrap silicon to be recycled generally includes the different silico briquette of shape, size, silicon leftover pieces, silicon cutting slag etc..It is useless in silicon
In the recovery process of material, need to enter subsequent technique just now after drying, screening twice technique after cleaning scrap silicon.But
Being that scrap silicon is usually directly laid on ground by existing scrap silicon drying process utilizes solar energy naturally dry, this technique
Although simple and easily operated, since scrap silicon size is different, dry required duration, the mode of drying are also different
's.For example, cutting slag particle diameter is small, the cutting slag and silico briquette of same volume are more compared to the chance that cutting slag is contacted with air, more
Add and be easy to be dried, but the gap cut between slag is smaller, it is therefore desirable to reasonably be placed so that the gap between cutting slag
There is air circulation, moreover, cutting slag also needs safekeeping, dries on the ground if be placed directly in extensively, may
It will lead to cutting slag loss；Silico briquette, the volume of silicon leftover pieces are bigger, and the time required for drying is longer, and work as part face energy
When the hard to bear heating to sunlight direct irradiation, part face possibly can not be irradiated by sunlight, the silicon adhered on the face due to wet
