The more massive coal particles (lower fineness) have more momentum when entrained in air at a certain velocity and are more easily stratified than finer coal particles that have less mass, thus lower momentum. After coarse and fine coal particles are separated fuel and air balance is further aggravated by imbalances in airflow.
