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 ...

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be ...

Seepage properties of crushed coal particles - CORE

Particle crushing during compaction is a main reason to increase small-size and emerge size 0–2.5 mm. Gas flow seepage properties of crushed coal are found to be strongly influenced by particle size and axial displacement. The permeability decreases and non–Darcy coefficient increases with the increase of axial displacement (decreases of porosity) and the decrease of larger particle size ...
