2018-12-7 · In his Third Theory of grinding, Bond (1952) observes that the net energy required in comminution has the same units one obtains considering the geometry of linear cracks inside spheres. This resulting power-based model with an exponent of -0.5 has been widely accepted and applied in conventional milling practices.
power-based design and analyses of conventional grinding circuits (Bond 1961). Bond''s third theory is presented in [1]. By rearranging the formula to [2], the operating work index (Wio) of an existing grinding circuit can be calculated, given known mill power draw, throughput, feed and product size distributions.
