Bond Work Index an overview ScienceDirect Topics
To investigate the influence of the coal type on the stampability factor K, stamping tests with eight different coals (C1C8 in Table 11.1) were carried out, using the Hardgrove grindability index (HGI) as a measure for the material dependency. The grindability is broadly defined as the response of a material to grinding effort.
Get Price Bond Grindability Test Procedure
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. To design a particle breakage system it is important to know the energy required to achieve a given size reduction.
Get Price 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. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal.
Get Price Hardgrove Grindability Index HGI Coal Analysis Testing
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.

Mining Hardgrove Grindability Index (HGI) The Hardgrove Grindability Index (HGI) is a measure of coals 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.
