CRUSHING  AND  REFINEMENT  OF  NONMETALLICS

Òhe technology is intended for crushing and refinement of materials having an artificial origin, obtained by chemical  reduction
and fusion or growth of crystals.
     ADVANTAGES:

  - attaining the preset fraction of crushing or refinement;

  - no dust release;

  - minimized overrefinement;

  - production rate, no less than,
  •   crushing – 1.0 t/h
  •   refinement – 50 kg/h.
