Clean Air Flow Test of a Pulverizer. Abstract. Pulverization of coal is carried out in two stages. Level of fineness is such that about 70% of fine particles pass through 200 mesh and about 98% pass through 50 mesh. Grinding inside pulverizers is realized by impact, attrition, crushing, or a combination of these.
