Grindability

Similarity of the curves shows that changing moisture-free weight of the standard samples is not a controlling factor in determining the trend of grindability with moisture content.

The breakage rate and breakage distribution functions were used to simulate the Bond batch grinds using the approach of Lewis et al [31], however, the simulated grindabilities deviated considerably from the measured results.

Pelletization is a proven technology for improving biomass properties, whereas torrefaction is considered a plausible alternative for decreasing the moisture content, increasing the energy density and greatly facilitating the handleability and grindability properties of the torrefied material.
