With respect to the FGX separator, the coal transport process and the distribution of the ash segregation degree under different vibration parameters were studied. The separation effect was optimal when the vibration amplitude reached mm and the vibration frequency was 18 Hz. The clean coal yield was %, and the ash content was %.

agglomerated coal was put back in the blender and mixed with 200 ml fresh tap water. After agitating the mixture for 2 min at the lowest speed, the coal slurry was poured back into the sepa ratory funnel where the agglomerated coal was recovered again. This washing operating was repeated once more to reduce entrapped impurities.
