15.10.2015 · The index varies from 20 to 110, with a lower HGI indicating a coal is harder to grind and more energy will be required to reach the required degree of fineness. The test is conducted on a standardised laboratory scale ball-and-race mill and is covered by BS 1016-112:1995.

### Fred Chester Bond - Wikipedia

In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the Bond Work Index, which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 …

### Relationships between comminution J energy and product ...

equal energy. Kick’s equation is as follows: [3] where E is the net specific energy; x f and x p are the feed and product size indices, respec-tively, and K2 is a constant. Bond (1952) proposed the ‘Third Law’ of grinding. The Third Law states that the net energy required in comminution is propor-tional to the total length of the new cracks formed. The resulting equation is ...
