Sieve Analysis and Determination of Grain Size ... - Weebly

The beneficiation of coal promotes homogeneity in the size of pulverized coal after comminution, as well as helping with the separation of impurities that result in ash and sulfur production when coal is burned. (1-2) One method of beneficiation is gravity separation via the screening of coal particles through sieves of decreasing size.
