Particle size distribution of coal and gangue after impact ...

The particle size distributions of coal and gangue under different impact velocities were researched according to the Rosin-Rammler distribution. The relationships between separation indicators and impact velocities were discussed. It is found from experiments that there is a fully broken boundary of coal .

Why Pulverized Coal is Used in a Power Plant

Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially available in different sizes known as "Run of Mine," "stoker," "slack," etc. depending on their size. In the olden days, coal burning was done on grates without any change in size or pulverizing.

Particle-size distribution - Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
