Hardgrove Grindability Index Wikipedia

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.

CONTRIBUTION TO DETERMINATION OF COAL GRINDABILITY

Hardgrove grindability index (HGI) is determining factor of energy consumption during grinding. The HGI value is used for more detailed coal reflectance of vitrinite. The grindability is significantly influenced also by the contents of ash in coal (Dinterová, 1976; Wang, 1996).

Reflectance Wikipedia

The reflectance of the surface of a material is its effectiveness in reflecting radiant energy.It is the fraction of incident electromagnetic power that is reflected at the boundary. Reflectance is a component of the response of the electronic structure of the material to the electromagnetic field of light, and is in general a function of the frequency, or wavelength, of the light, its
