Sluices and spirals rely on the difference between viscous drag and buoyancy for particle separation. This difference is directly related to particle size. Gravity tables use a vibrating platform to separate by particle size and specific gravity. Thus, narrow size distribution feeds result in better separation.

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.
