Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

Principles of Screening and Sizing

• Maximum bed depth at discharge end is 4x the separation. • If too thick, probability is decreased for sized aggregate to properly stratify and pass through an opening. • Minimum bed depth is 1x the separation. • If too thin, material can bounce, stay suspended and not stratify or find an opening, thus reducing accuracy.
