RittingerThe Bond work index (Bond, 1960) is based on Bond's law, which states that the energy consumed is proportional to the power of particle size rather than the square of Rittinger's law. Accordingly, the energy consumed in reducing the particle size from x F to .
Chemical Engineering Stop: Bond's lawMay 14, 2010 · Bond's law. Bond postulated that work required to form particles of size Dp from very large feed is proportional to the square root of the surfacetovolume ratio of the product, Sp/Vp. By relation Sp/Vp = 6/ɸsDp, from which it follows that. P/ ṁ = Kb/ (Dp)^ Where Kb is a constant that depends on the type of machine and on the material ...
Comminution testingJul 30, 2020 · A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus mm, as required for the Bond Ball Mill Work Index test feed.

GeometallurgyGeometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants. It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design. It is also used, to a lesser extent, for ...
Crushing Law And Work IndexChapter 3 Particle Technology (Size Reduction) Bond crushing law and work index. The work required to form particles of size Dp from very large feed is proportional to the square root of the surfacetovolume ratio of the product, sp/vp.
size reductionMar 13, 2015 · Bond's theory 22. 1. Bond's work index is the work required to reduce unit weight from a theoretical infinite size to 80% passing 100µm. 2. This theory is useful for rough mill sizing. 3. The work index is useful for comparing efficiency of milling operations 23. Kick's Theory 24.
