The Bond work index (BWI) is a well-known method used when selecting comminution equipment, to evaluate the grinding efficiency and to calculate the required grinding power.

The Bond method allows for quantification and com-parison of relative energy efficiencies of most industrial comminution circuits. It is an essential tool for managing the important business (cost) of grinding. For early analyses of plant grinding efficiency issues, see Bond (1957, 1960). 5.SCOPE This Bond Efficiency determination applies to most

The Bond Index conforming rod charge consists of: 6 rods of 1.25" diameter and 21" length. 2 rods of 1.75" diameter and 21" length. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

Thank you very much for your reply. We might have a different version of Bond's work then. I checked the values on "Crushing and Grinding Calculations - Part II" from 1961 on Table IIIA. I don't have access to the link you sent. From the paper, the value for Andesite is 22.13. Best regards

The relationship between the comminution energy and the product size obtained for a given feed size has been a researched extensively over the last century. Theoretical and empirical energy-size reduction equations were proposed by Rittinger (1867), Kick (1885) and Bond (1952), known as the three theories of comminution; and their general formulation by Walker et al. (1937).
