    Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution the size reduction of particles is done by three types of forces compression impact and attrition.

    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
