    Pulverizer Capacity Is Not Simply Tons Throughput Per

    pulverizer capacity. Capacity of a pulverizer is a minimum of five factors and these five factors are: tons throughput at a given fineness, at a given Hardgrove grindability index (HGI), at a given raw coal sizing entering the mill and at a given coal moisture content. Throughput alone is NOT a definition of pulverizer capacity! Please read on

    particle sizing. 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.
