The screen surface load (SSL) caused by granular materials is an important factor affecting the structural performance of vibrating screen. Based on virtual experiment, a multi-objective collaborative optimization method is proposed to control the SSL under high screening efficiency (SE) in this work.
Compared with traditional linear vibrating screens, the force, stratification mechanisms, and throwing principles of the material on the screen's surface were studied, and the vibrating screens' material transportation and screening efficiency were analyzed.

Vibrating screens are a widely applied form of particle separations. In spite of this significance, their understanding is still an obstacle. Three approaches were used to characterize the flow of granular material in a linear vibrating screen. The statistical model, mass action, and kinetic model based on conservation of momentum were derived.
It is demonstrated that changing the shape of particles is a practical way of managing real screening work and provided a theoretical basis and reference for the design and applications of multi-layer vibrating screens. This paper investigates the screening characteristics of the multi-layer vibrating screens. A portable linear screen with a three …
