lignite hardgrove index

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.

Diffuse reflectance spectroscopy - Wikipedia

Diffuse reflectance spectroscopy, or diffuse reflection spectroscopy, is a subset of absorption spectroscopy.It is sometimes called remission spectroscopy.Remission is the reflection or back-scattering of light by a material, while transmission is the passage of light through a material. The word remission implies a direction of scatter, independent of the scattering process.

Reflectance of the chars increases as the holding time becomes longer (Fig. 3).At 600°C, however, the reflectance of the Ca char increases more quickly than that of the raw char. When the holding time is shorter (0 and 5 min), the raw char shows a higher reflectance, but after 30 min the reflectance of the Ca char becomes higher than that of the raw char.
