3.1 This test method provides a means for assisting in the evaluation of pulverizers and pulverizer systems in terms of fineness specifications. It may also be used to confirm the influence of coal fineness on combustion performance and to evaluate carbon loss. By consent among interested parties, it may be used for evaluation of coal fineness in preparation, pneumatic transfer systems, etc.
Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal …
how to improve coal fineness in xrp 763 coal mill. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance.

Pulverised Coal - an overview | ScienceDirect Topics
The adverse effects are compounded because burners having more coal will likely be of lower fineness making it even more difficult to achieve complete combustion in the burner belt zone. Importance of Fineness. Poor Coal Fineness often yields poor distribution as large coal particles & air mix to form a (2) phase mixture which will not homogenize.
· The Hard grove index, total moisture, input coal size, output fineness, and mill wear have direct impact on the mill output. The Hardgrove index of coal tells us about the ease with which it can be pulverized. A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill.
