vibration parameters determines the screening performance [1, 2]. In order to improve the imperfect screening theory, the separation process is divided into four parts: looseness, stratification, percussion and penetration. Numerical modeling using DEM has been proven to be a useful tool to simulate the complex process of sieving phenomenon [3, 4].

2021-4-21 · Screening Theory and Practice 1 Part 1. Theory of Screening The purpose of screening is to separate from a granular substance particles that are smaller than the screen opening from those that are larger. This is not as simple as it sounds, and the difficulties compound as the opening becomes smaller. For example, if a sample of a crushed
