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
the Hardgrove grindability index is known to be indirectly proportional to the hardness of the material, NCB cone indenter tests can be considered to succeed in reflecting the differences found in the Hardgrove grindability values between the A05 and F02 panel coals (Fig. 8). 455

In my case we are using both Hardgrove and Bond work indexes for different Kaolin samples. I am looking for to secure more information about HGI of clays; especially different Kaolin samples.
The Hardgrove Grindability test is commonly used to characterize the milling behavior of coals. The test, first conceived by Hardgrove (1931) and later modified to the current constantweight test in 1951 (ASTM D40971, 1971; ISO 5074, 1994c), attempts to mimic the operation of a continuous coal pulverizer using a batch process. As noted by Hardgrove (1931) and others (Roth et al., 1992; Hower

Hardgrove Grindability Index analysis is the ASTM method of determining the hardness of coal when pulverized for steam generation or size reduction. Grindabilities typically range on coal from 35 110. Harder and less grindable coal rates a smaller HGI index number.

Hardgrove Grindability Index (HGI) The Hardgrove Grindability Index (HGI) is a measure of coals resistance to crushing. Read more. Grinding studies, and the resulting HGI, allow many different types of coal users to evaluate how coals will perform in their mills, allowing them to estimate grinding power requirements and throughput capacities.

Grindability refers to the ease of pulverizing a coal sample compared to certain reference coals. The standard method of coal grindability is called Hardgrove (ASTM D409), though this method does not provide reproducible and repeatable results for hard coal. Another method that can be accepted for petroleum coke is the test method ASTM D5003.
25/06/2019#0183;#32;The test for coke hardness is Hardgrove Grindability Index or HGI. The test method is ASTM D5003. It is the same method for testing the grindability of coal which is covered in test ASTM D409. The test uses a crushed sample of petroleum coke and then screens that sample for a particular size. That is put into the Hardgrove machine that is a ball mill and run 60 revolutions. The amount of

Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined empirically using a sample mill according to the following procedure:
