The Hardgrove Grindability Index was developed as an empirical test to indicate how difficult it would be to grind a specific coal to the particle size necessary for effective combustion in a pulverized coal fired boiler. Its use has been extended to cover the preparation of pulverized coal for the cement, steel and chemical production industries.

The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured. The grindability is useful in evaluating power requirements for grinding.
The Hardgrove Grindability Index Standard Reference Sample (HGI-SRS) is a sample of coal used to calibrate instruments that are designed to determine the ease with which coal can be pulverized. The HGI value provides information for determining grinding power consumption and pulverizer capacities.

May 01, 2013· The Hard grove method ismostly used to determine the grindability ofcoal, but also in determining grindability ofother raw materials. Bond's method is used toevaluate the rock grindability. 4. HARDGROVEGRINDABILITY INDEX (HGI)• The Hardgrove Grindability index is designed todetermine the ease with which coal can bepulverized.•
The Hardgrove Grindability Index (HGI) is a measure of coal's resistance to crushing. 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.
The percent by weight of the coal that passes through a 200-mesh sieve (a screen with openings of 74 micrometres, or 0.003 inch) is used to calculate the Hardgrove grindability index (HGI). The index is used as a guideline for sizing the grinding equipment in a coal-preparation plant. Porosity

Determination of work index is time and labour consuming therefore, grindability index, most commonly known as hardgrove grindability index (HGI) is preferred for predicting the grinding behaviour of coal and energy consumption requirements of mill (Tichanek, 2008).
Since the brittleness and the Hardgrove Grindability Index (HGI) of vitrain are lower than those of fusain [39], the vitrinite gathers in large coal particles and can be easily broken into pieces, while the inertinite gathers in small coal particles and can be easily broken into powder.

3 FACTORS AFFECTING THE HGI GRINDABILITY VALUES . The Hardgrove grindability index value is influenced by petrographic composition of coal. The analysis of grindability of British coal confirmed wide relation of HGI values between the quality group of coal, volatile combustible matter contents, carbon and hydrogen (Fitton, 1957).

for grindability testing on the grounds that it contains an ac cumulation of the more resistant components of the coal, but it is our belief that, if the sample is alternately screened and crushed, the final sized sample will be as nearly representative as that produced by any other means. Coal "in place" is quite
How is Hardgrove Grindability Index (energy industry) abbreviated? HGI stands for Hardgrove Grindability Index (energy industry). HGI is defined as Hardgrove Grindability Index (energy industry) frequently.
Oct 15, 2015· Bond Work Index (BWI) & Hardgrove Grindability Index (HGI) tests for biomass & coal. • BWI can predict the potential for mill choking of biomass in a tube and ball mill. • HGI is a poor method of predicting grindability of biomass in vertical spindle mills. • Pellets should be composed of pre-densified particles close to the target size. •
Hardgroove Grindability Index (HGI) means the ease level (index) of coal to get grinded. The higher it is means the easier for coal to be grinded. This HGI parameter could also used to explain the hardness level of coal. The lower it is means the harder the coal.
This recent order is a repeat order of the MPS 4000 B vertical roller mill supplied in 1999. The mill type chosen for the required cement raw meal capacity of 240 t/h at a fineness of 12 % R 0.090 mm is again an MPS 4000 B. Compared to the mill in operation, which is fitted with a 1,250-kW drive and producing the same capacity, this mill will come equipped with a 1,600-kW drive due to a poorer ...
