Standard Test Method for Hardgrove Grindability Index (HGI) of Petroleum Coke
SIGNIFICANCE AND USE
5.1 The HGI is used to predict the ranking of raw petroleum cokes or calcined petroleum cokes in industrial size mills used for crushing operations. The rankings are based on energy required and feed rate or both.
5.2 The HGI is also used to select raw petroleum cokes and coals that are compatible with each other when milled together in a blend so that segregation of the blend does not occur during particle size reduction.
SCOPE
1.1 This test method covers the determination of the hardgrove grindability index (HGI) of those petroleum cokes that contain no dedusting additive. The procedure for this test method is the same as in Test Method D409. Sections of this test method contain the significance and use of the HGI of petroleum coke, preliminary sample preparation procedures, and procedure and precision and bias data specific to petroleum coke.
Note 1: The size consistency (particle size distribution) of fluid petroleum coke is generally 100 % passing a 6.7 mm [0.265 in.] sieve and greater than 80 % passing a 2 mm [No. 10] sieve. Much of fluid cokes will pass a 600 μm [No. 30] sieve. Because of this fineness the HGI value is related to the coarser particles in fluid coke and large samples are required to prepare sufficient material of the correct particle size for Test Method D409.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.2.1 Exception—Hardgrove grindability index is unitless.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
Introduction of petroleum coke into the coal market in recent years has necessitated the use of many
of the test methods for coal so like data would be available for comparison and blending purposes. Test
Method D409 does not cover petroleum coke in its scope and its statements of precision and bias do
not include petroleum coke. This test method provides the procedures and precision and bias data for
the hardgrove grindability index (HGI) of petroleum coke. Use of this test method or Test Method
D409 produces the same value for the sample of petroleum coke being analyzed.
