Kinematic Law of Solids on a Drilling Fluid Vibrating Screen

Abstract

Based on solid-liquid two-phase flow theory and dynamic principle of a vibrating screen, the kinematic behavior of solids on the vibrating screen is studied. In submersed condition, the formula of suspension size of solids, the terms of free flight and suspension motions are developed, and the kinematic behavior of solids when they enter free flight is discussed. After the liquid endpoint, the kinematic terms of sliding backward and forward, free flight, remaining in contact with the screen and staying stationary on the screen for solids are obtained, and a mathematical model that can predict solids conveyance velocity is developed.
