Note that the definition of particle size in Bonds law is different: D80= Particle size such that 80% by weight of the sample is smaller than it. Bonds law is often written in terms of the work index (Wi) as, Where the work index is defined as the energy required per unit mass in kWh/ton to reduce an infinitely large particles to D80 = 100 μm.

Crusher - Wikipedia

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 ...

Now RETSCH offer, for example, a series of jaw crushers with feed sizes from 40 mm to 350x170 mm. The new XL models of ball mills, vibratory disc mills and sample dividers provide a substantially higher throughput than the laboratory-scale models. The new portfolio also includes a number of testing equipment to determine the Bond Grinding Indices.

Bond Work Index - an overview | ScienceDirect Topics

Bond Work Indices were also back-calculated from the data using the standard formula, i.e. where F80 is defined as the length of the side of the cube of the same weight as the average particle. Confirmation of the ability of the procedure to provide information suitable for the prediction of crusher performance was obtained by taking feed ...
