Background technique
Polysilicon is fabricated to silicon wafer to be processed after the programs such as ingot casting, broken ingot, slice, on silicon wafer doping with
Micro boron, phosphorus etc. are spread, P-N junction is just formed.Then silk-screen printing is used, the silver paste that essence prepares is imprinted on silicon wafer and is made into grid
Through oversintering, while back electrode is made in line, as soon as and apply layer anti-reflection coating in the face for having grid line, cell piece is so far made.
During the cutting technique of silicon wafer, more silicon slag can be generated, recycling part silicon cutting slag can significantly
Reduce production cost.Before the recovery process of silicon cutting slag, need to carry out the pretreating process such as drying, the screening of silicon slag.For
Integrate drying, the sieving technology of silicon slag, so as to shorten when chief engineer and drying efficiency is improved, inventor devise for silicon slag from
The airing device so dried.The airing device not only increases drying efficiency by combining sieving technology and drying process,
Also eliminate subsequent sieving technology.
After completing drying, need silicon material and silicon slag classification transport to process equipment carrying out subsequent processing.But it is traditional
