Conclusions:
In a sief test performed according to ASTM D1921, the particle size of Potassium ferrocyanide was determined to be <1.25 mm and >=0.4 mm. Particle sizes were distributed as follows: 23.3% <1.25 - ≥0.6 mm, 33.2% <0.6 - ≥0.4 mm, 36.4% <0.4 - ≥0.2 mm, 4.7% <0.2 - ≥0.15 mm and 2.4% <0.15 - ≥0.04 mm.
