Bond Work Index - an overview | ScienceDirect Topics
The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

In the Bond equation, the feed F is the feed to the grinding circuit and the product P is the product from the grinding circuit. In an open circuit, this is straightforward but in a closed circuit mill, where a classifier is installed to return the course fraction to the mill, the work index is …
Fred Chester Bond - Wikipedia
Bond Work Index. 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 journal article. Bond called his theory the "third theory of comminution", counting ...
