Chat OnlineBond 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
Chat OnlineThe standard bond rod mill work index test procedure is firstly to stage crush the feed to pass 127 mm and size a representative sample the test then involves a series of batch grinds in a standard bond rod mill a bond rod mill is 0305m by 0610m with wave liners of a form described by bond which runs at 40rpm and tilts as described below
