The Hardgrove Grindability Index is calculated on four splits (or portions), two each taken from the two reserved cans. The results are averaged to give the index for the entire lot. Cans of standard reference sample are shipped to customers upon request, along with a questionnaire designed by ASTM to obtain data on the quality of the sample.

Hardgrove Grindability Index . 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. ... Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives ...
Petroleum coke regularly known as a pet coke is a carbonaceous strong conveyed from oil refinery.This coke can either be fuel grade or anode grade. Petcoke is more than 90 percent carbon and radiates 5 to 10 percent more carbon dioxide than coal on a for every unit-of-vitality premise when it is blazed. ... Hardgrove Grindability Index (HGI)-38 ...
Petcoke (petroleum coke) is a bottom of the barrel product. It is a dark solid made of relatively pure carbon. It is produced at the delayed coker unit (DCU) in the refinery. ... Hardgrove Grindability Index (HGI) - 38 - 52 . Low value indicates difficulty in grinding. Petcoke.

The Hardgrove test is a standard method used wide-ly in the coal industry. To determine the relative grindability of coal, i.e. whether it is easy or difficult to pulverize, the Hardgrove grindability index (HGI) can be estimated from the test. A higher index indicates the coal is easier to pulverize.
Grindability of coal is generally estimated by two indices: (a) work index in which energy consumption for obtaining product of constant fineness is measured; and (b) grindability index in which fineness of final product is measured for same grinding work of the standard samples. ASTM, 2004 (D409-02) was followed for determining hardgrove ...
A. A Boateng, in Rotary Kilns (Second Edition), 2016. Abstract. Petroleum coke is a by-product of the coker process in the oil industry. In its raw form, it is also called "green coke" or green petroleum coke. Calcined petroleum coke is an important industrial commodity that links the oil and the metallurgical industries as it provides a source of carbon for various metallurgical ...
The contracts provide that the petcoke must have an HGI (Hardgrove Grindability Index) of "36-46 typ." The parties explain that typ. stands for typical, and that the lower the HGI, the harder the petcoke is to grind and process. According to the analysis, the petcoke had an HGI of 32.
