Hardgrove index is commonly used to determine power requirements of vertical coal mills. Relation between BWI and Hardgrove Index can be described by the following equation. B.W.I. = 435/(H.G.I.) 0.91. GRINDING MILLS. Mills will be selected according to type most suitable for required capacity and duty and for overall power consumption.
The dashed line estimates the increase in mill capacity in going from a high-volatile B bituminous coal with a 55 HGI, 12% moisture and a desired mill output of 70% through a 200 mesh screen to a highvolatile B bituminous coal with an HGI value of 60, a moisture content of 14% and the same fineness.

Coals used for power plants normally have different ash contents, and the breakage of coals by the ball-and-race mill or roller mill is an energy-intensive process. Grinding phenomena in mill of power plants is complex, and it is also not the same with ideal grinding tests in labs. The interaction among various coals would result in changes of grinding behaviors and energy …
Ubiquity of Reactive Oxygen Species. As reviewed by Lane and Maina (), the primary atmosphere contained mainly nitrogen, carbon dioxide, and water vapor.Much of these were swept away by meteorite bombardment and replaced with a secondary atmosphere (416-418, 579, 590) consisting of hydrogen sulfide, cyanide, carbon monoxide, carbon doxide, methane, and more …
