Silica (Silicon Dioxide) is difficult to discharge due to its flow characteristics of flushing and bridging.

Silica is used for electronic devices as well as in cosmetics and medicines.

  • Difficult to handle because of its adhesive properties.
  • It is fine-grained and has a low bulk density of 50 kg/m3.
  • Use of a CF ∑ is recommended to address its proneness to flushing.
