Standard Test Method for Hardgrove Grindability Index (HGI) of Petroleum CokeMore info
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 6.73 mm (No. 3) sieve and greater than 80 % passing a 2.00 mm (No. 10) sieve. Much of fluid cokes will pass a 0.59 mm (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.
