2021-5-1 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. Although considered an industry standard, Bond did not fully define that procedure, and therefore significant discrepancies in test results can sometimes be obtained due to

This paper investigates grinding of mineral mixtures with different grindabilities in the Bond ball mill. Understanding the ore mixture grinding is of great importance in mineral processing. The energy required for crushing and grinding is presented by the Bond work index and is determined by means of Bond grindability test. This paper presents the experimental results of the Bond work index

1989-1-1 This enables a more objec- tive identification of the energy required for grinding in the case when, for a certain grinding-product size, we do not dispose of the appropriate work-index value established by experiments. 46 REFERENCES Bond, F.C., 1961.

2014-10-1 Bond Third Law of Comminution Comminution theory is concerned with the relationship between energy input and the particle size made from a given feed size. The best known and most widely used power-based equation is that proposed by Bond (1961) and is given in Equation 1. Bond’s Third Theory of Comminution is an empirical

In previous publications, we have described how the size specific energy (SSE) can be calculated to predict the energy required to generate new minus 75 µm material. However, if we want to benchmark the performance of fine grinding where the product can be much finer than 75 µm, clearly we require a finer marker size. If we do this, we also need a way to compare results that

Blasting has an important impact on mining and milling well beyond the necessary ability to dig and load the ore efficiently. There is an increasing body of blasting research indicating significant impacts in crushing and grinding. These include increased production through higher output and fewer delays for bridging and jamming by oversize. In addition, fragmentation better suited to the

Bond’s equation was developed for the purpose of designing conventional crushing and grinding circuits (crush-rod-ball mill or crush-ball mill). By the 1970s, the application of

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).
