CLASSIEL® is a high performance separator which has been developed based on the technology of O-SEPA® aiming at classification of fine material such as raw material of ceramics and calcium carbonate for paper filler and coating.


  1. Excellent performance

    CLASSIEL® has high performance sealing system to avoid coarse size grain from mingling with the fine product.
    CLASSIEL® can achieve the sharp cut as passing rate through 45μm sieve of 99.999% is possible for classification of calcium carbonate powder.

  2. Wide classification range with easy control

    CLASSIEL® can easily control wide classification range (3-200μm) by changing rotor speed and/or air flow rate.

  3. Sharp and High efficiency classification

    CLASSIEL® can perform high efficiency even in case large size model CLASSIEL® as classifying tens of ton/h.

  4. Best Suited design

    CLASSIEL® can be customized complying with customer's request.


  • Calcium carbonate, Coal, Cement, Perlite, Silica sand, Fly ash
  • Raw material for ceramics, Raw material for grass, Black lead, Charcoal
