Bond's grindability. associated with tumbling mills (PrasherJ987). Bond's grindability can be empirically related to the energy required for comminution and thus is useful for the design and selection of crushing and grinding equipment (Deniz et al., 1996). İn the recent years, matrix model and kinetic

Sep 01, 2017 In this way, higher Bond index for a material implies that it has lower grindability. The third theory of Bond is commonly written as Eq. (1) ; (1) W = 10 Wi 1 P 80 1 F 80 where W is the input energy in terms of kWh/ton, Wi is the Bond work index in kWh/ton and P 80 and F 80 are the 80% passing sizes of product and feed in micrometers.

March 26, 2021 Grindability is a crucial parameter in mineral processing, and it refers to the easiness at which materials can be ground. Bond’s Work Index (Wi) is widely considered to be the most accepted way to measure ore grindability. Bond’s Work Index is a number that basically represents a material’s resistance to comminution. Table 6. Final Grindability Values for the different

Dec 04, 2020 The bigger picture is "Bond's Law" isn't a law at all, it is just a regression line drawn through a bunch of data collected in the 1930's and 1940's that "kinda-sorta" had a slope of –½ when

Screen Analysis of Feed Using the equation of the line in the figure above, the 80% passing size was calculated to be 1328.61 µm. Next to be determined was the grindability, G. To get G, a 250 percent circulating load was to be achieved.

Mar 08, 2012 The grindability of clinker is closely related with the burning condition. Although, the mechanism of grinding is not clear, statistic analysis between grindability and burning condition, and microscopical four terms, gives us distinct regressive equation. The
