The document outlines the ASTM D4749 – 87 (Reapproved 2007) standard test method for performing sieve analysis of coal and designating coal size. It details procedures for determining the particle size distribution of raw and prepared coals, excluding pulverized coal. The standard specifies apparatus requirements, including types of sieves and mechanical shakers, as well as methods for sample collection, preparation, and analysis. It also provides guidelines for reporting results, including size designation based on sieve analysis data.

What is the method of coal analysis?

The document outlines the ASTM D4749/D4749M standard test method for performing sieve analysis of coal and designating coal size. It details procedures applicable to both raw and prepared coals, specifying the scope, referenced documents, and definitions related to coal testing.

What is sieve analysis of coal?

Sieve analysis test is a test that measures the yield and quality characteristics of each particle size of coal samples less than 0.5mm through a standard sieve, also known as a small sieving test.

What is the main purpose of sieving?

Sieving is probably the easiest and most widely used method for separating components on a size basis in powders and also for measuring particle size distribution. It provides the means of determining the success or the end of a milling or grinding process, for example for producing flour or grinding materials.

How do you interpret sieve results?

When you hear the term test sieve analysis results, it is referring to the distribution of particles in a given sample. This can be interpreted by analyzing the retention of particles throughout a sieve stack or the amount of material that passes through each sieve.

How to perform sieve analysis?

This is achieved by any of the following methods; Heating the coal with toluene. Drying in a minimum free-space oven at 150 C (302 F) within a nitrogen atmosphere. Drying in air at 100 to 105 C (212 to 221 F) and relative loss of mass determined.

What is the main purpose of sieve analysis?

Sieve analysis determines the particle size distribution of a given soil sample and hence helps in easy identification of a soils mechanical properties. These mechanical properties determine whether a given soil can support the proposed engineering structure.
