Silicon granule ­etching plant.

During the pro­ces­sing of poly­crystal­li­ne sili­con or during wafer pro­duc­tion, a cer­tain amount of breaka­ge can hard­ly be avo­ided.

Resource-efficient and cost-effective.

With this recy­cling sys­tem, not a sin­gle gram of valuable sili­con is lost! „Old wafers“ or bro­ken wafers are shred­ded and repro­ces­sed. The capa­ci­ty is up to 1,000 tons of recy­cled gra­nu­la­te per year.

Key facts:

  • Ful­ly auto­ma­tic crus­hing, etching, dry­ing, por­tio­ning, pack­a­ging

  • Tar­ge­ted extra­c­tion of harmful gases with sub­se­quent clea­ning
  • Per­ma­nent moni­to­ring of essen­ti­al pro­cess para­me­ters

Customer benefits:

  • Annu­al capa­ci­ty: 60 kg / h x 6,600 h = 396 t p.a. mini­mum

  • Redu­ces cos­ts in the long term

  • Few che­mi­cals & rin­sing water

  • Pro­du­ces high-qua­li­ty sili­con

  • Inno­va­ti­ve dry­ing con­cept

  • Pack­a­ging under clean room con­di­ti­ons

  • Indi­vi­du­al turn­key solu­ti­on

  • Fine-grain etching system for shredding "old wafers" or wafer breakage
