SILMIKRON® is for industrial use, mighty, workable silica sand deposits are of decisive importance. Nevertheless, chemical purity and constancy are not enough in order to apply silica directly as a raw material. In Quarzwerke plants silica sands are thoroughly prepared. The raw material has to pass exten-sive cleaning-, classification-, drying- and iron-free grinding processes in order to produce silica sands, flours and powders. For the production of silica flours and -powders with a defined grain size distribution separation processes are required in addition to iron-free grinding. Quarzwerke are able to produce silica powders with grain sizes down to 1 μm due to a fine-tuned combination of grind- and classification technology.
