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).

The Rittinger theory is the older and more widely accepted. In its first form, as stated by P. R. Rittinger, it postulates that the useful work done in crushing and grinding is directly proportional to the new surface area produced and hence inversely proportional to the product diameter.

where L P and L F are representative size of product particles and feed particles in millimeters, respectively. K R, J mm g −1, is the Rittinger constant; K K, J g −1, is Kick's constant; and K B, J mm 0.5 g −1, is the Bond constant.. The basis of the Rittinger theory is that the energy consumed for grinding is proportional to the surface area created.

The Hardgrove grindability test, commonly used in coal characterization, was conducted on 13 Mississippian carbonates from Kentucky, Tennessee and Illinois. The results demonstrated that the grindability increases with a decrease in the SiO2/(MgCO3+CaCO3) ratio, with fine-grained and petrographically-complex stones having lower grindabilities. Also, the …

Costs of grinding the magnetite to a suitable size can be estimated using the Bond work index for grindability (F.C. BOND. Crushing and grinding calculations. Brit. Chem. Eng. 6(8), 1961, 543-8) ##EQU7## where W i is the work index, equal to about 10 for magnetite, F is the feed size (80% passing) (m), and P is the product size (80% passing) (μm).

Research is underway to develop laboratory testing procedures for the milling of magnetite ores that would aid in equipment sizing and selection. REFERENCES Bond, F.C., 1962.

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 …

Modelling of grinding circuits is crucial for circuit design and optimization. Determination of breakage distribution function of the materials is important for accurate and reliable modelling. In this study, the model structure was focused on using separate breakage tests for each chamber.

Hukki (1962) evaluated these energy-size relationships stating that each of Rittinger, Kick and Bond theories might be applicable for different narrow size ranges. Kick's equation is applicable for crushing, Rittinger's equation may be used for finer grinding, and Bond's equation is applicable in the conventional milling range.
