The sieve analysis described is applicable to all coal except anthracite, powdered coal as used in boiler plants, and crushed coal as charged into coke ovens. The coal should be sampled when it is being loaded into or unloaded from railroad cars, other means of transportation, or other types of coal-conveying equipment.
What Is A Sieve Analysis? Sieve analysis, or gradation testing, is a method used to determine the particle size distribution of granular materials, such as crushed rock, sand, clay, granite, etc. Sieve analysis is used in civil engineering because the distribution of different grain sizes can affect the engineering properties of aggregates.

A sieve method of analysis for determining the particle size of crushed bituminous coal is described. The method is applicable to coal less than 1/sup 1///sub 2/ in. (38.1 mm) in size.
As-mined coal must be crushed and sized to manageable particle sizes for either utilization, or for feed to a preparation plant. ... The design objectives for intermediate coal screening are similar to those for coarser coal, except that the sieve openings must be made significantly smaller. To achieve this, the materials used to define the ...
The crushed coal, 6–10 mm size is conveyed from coal bunker to a spreader by a screw conveyor. The spreader distributes the coal over the surface of the bed uniformly. This type of fuel feeding system accepts over size fuel also and eliminates transport lines, when compared to under-bed feeding system. 2. Air Distributor
