  2. CASE STUDY

  3. RawCoals • 9 coals with different washability potential • From seam III to seam VIII • Raw coals were crushed to 75 mm • Only one coal was crushed to 13 mm • Separated into 2 sizes (75-6 & 6-0.5 mm)

  4. Aim To beneficiate optimallyat an ash level of16.5 to 17.5 %

  5. Rawcoalcharacteristics

  6. Circuit“I” • Each separately crushed & screened • Coarser 75-6 mm fraction • Smaller 6-0.5 mm fraction • Beneficiate each fractions to 17 % ash • Composite yield - Blended cleans

  7. Circuit“II” • Blending of raw coals • Crushed & screened to, • Coarser 75-6 mm fraction • Smaller 6-0.5 mm fraction • Beneficiate both fractions to 17 % ash • Composite yield - Blended cleans

  8. Results
