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

2018-5-12 The procedure involves grinding the material in increasing time intervals until the required product specification (P 80) is achieved. The specific energy for the test material (kWh/t) was calculated from the measured net power draw (kW), mass holdup (t) and grinding time (h) to achieve the product specification. The specific energy

2020-6-1 S i E values can be used as indicators of grinding energy efficiency since breakage rates are proportional to specific power input and irrelevant to how a grinding process is operating. However, the S i E only indicates rate of breakage occurrence from an energy-input viewpoint, and does not involve breakage distributions.

Grinding force ratio is a parameter that gives indirect information about the efficiency of grinding. Force ratio is defined as: (2.8) μ = F t / F n grinding force ratio When grinding with sharp wheels grinding force ratio is high since normal force is low compared to tangential force.
