    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.

    Aug 05, 2015  The desirably sized barite that is discarded by the high-speed solids control centrifuge must be replaced by fresh barite, 30 percent of which can be particles finer than 6 μm, and 10 percent of which can be expected to be colloidal (less than 2 μm). This further reduces average particle size and accelerates the decline of drilling fluid quality.

    Aug 05, 2015  Bentonite particle size distribution can range from less than 1 to 10 μm (colloidal and smaller ultrafine solids). Bentonite solids have a much smaller particle size distribution than barite. This is the reason that bentonite is typically considered a thickening agent to increase viscosity, while barite is simply considered a weighting agent.
