His theory and index were introduced in a widely cited 1952 journal article. Bond called his theory the "third theory of comminution", counting those of Peter von Rittingerand Friedrich Kick as the first and second.

Size Reduction of Solids Crushing and Grinding
Abstract. The unit operation of the size reduction or comminution of solids by crushers and mills is a very important industrial operation involving many aspects of powder technology. It is estimated that mechanical size reduction of rocks, ores, coals, cement, plastics, grains, etc. involves at least a billion tons of material per year in the United States alone.CHAPTER 11 SIZE REDUCTION - NZIFST,2019. 2. 24.· CHAPTER 11 SIZE REDUCTION Raw materials often occur in sizes that are too large to be used and, therefore, they must be reduced in size.
