Similarly, coal rank can also affect HGI, as low-volatile and medium-volatile bituminous coals are easy to grind compared to lignite and anthracite coals (Berkowitz, 1979). The correlation between HGI and coal rank (or vitrinite reflectance) is shown in Fig. 2.2 .

It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a centrally located feed pipe to the center of the grinding table.

The results are compared against a standard sample to provide the index and used to determine how much energy and expense will be needed to grind down a certain coal for a particular use (ASTM method D409-12; American Society for Testing and Materials, 2013, p. 397–411). The HGI is on a scale from 30 to 100.

Subbituminous coal typically contains 35%–45% carbon, compared with 25%–35% for lignite. About 46% of the coal produced in the United States in 2020 was subbituminous. Bituminous coal contains 45%–86% carbon and has two to three times the heating value of lignite. Bituminous coal was formed under high heat and pressure.
