The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

The behaviour of coarse pure lead particles in different dry laboratory tumbling mills was investigated. It was modelled with first-order transfer rates to represent the various mass transfers observed, namely flattening, folding, agglomeration, breakage and smearing unto the mill shell and grinding media.This paper presents the models used and the experimental program of the grinding …

The grinding is the last stage of comminution in a mineral processing plant, responsible for reducing particles in size by mechanisms of fragmentation, impact, compression, and shear. Moreover, it is one of the stages that requires greater focus due to the more energy-consuming and major investments requirements. The grinding is considered very important for the mineral concentration process ...

The grinding theories, also called hypotheses or laws, are known by the surnames of their authors, such as: Rittinger, Kick [37,38,39], Bond [40,41,42] and Charles [43,44,45]. The theory of Rittinger assumes that the energy introduced in the process of grinding once is proportional to the increase in the surface resulting from the formation of ...

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.

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 theory of comminution", counting ...

Bond Grindability Tests are used to provide basic data for designing industrial comminution circuits. The Bond Work Index (W i) of an ore is determined by Bond Grindability Tests that indicate resistance the to comminution.The work index is very important but its determination is time consuming and requires skilled staff and 10 kgs of specially prepared feed sample.
