Bond Work Index (Energy equation)

BOND WORK INDEX. The Bond Work Index is a factor that measures the energy consumed in size reduction operation of the ore. The Bond's Work Index equation is: W=WI* (10/√P80 10/√F80) where. W= the energy input (Work input) per ton, kwh/metric ton. WI= Work Index= specific energy per ton, kwh/metric ton (characterizes the ore)

To measure differences in size distribution of dry aggregates, Chepil (Chepil Bisal, 1943; Chepil, 1962) developed a rotary sieve that could separate

Bond Work Index

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 ...

Quantifying the energy efficiency of fine grinding ...

In previous publiions, 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

Behavior and Splice Length of Deformed Bars Lapping in ...

This paper discusses the behavior of grouted noncontact lap splices under monotonic tension load. Deformed bars lapped through a groutfilled corrugated duct, and a spiral reinforcement was preembedded in the connection to improve tensile strength of the splice. The experimental results show that bond failure splices are always failed by the pullout of the preembedded bar other .

Atterberg Limits Soil Classifiion

· A. Atterberg defined the boundaries of four states in terms of "limits". A finegained soil can exist in any of several states; which state depends on the amount of water in the soil system. When water is added to a dry soil, each particle is covered with a film of adsorbed water. If the addition of water is continued, the thickness of the water film on a particle increases.
