Fractal evaluation of particle size distributions of chromites in different comminution environments
A. Taşdemir, Auteur
|
Particle size distributions (PSDs) are often rendered as cumulative functions, either as number of particles larger than a certain diameter, or as mass smaller than a certain diameter. The fractional exponent of the number/mass-size power law ha[...]
