Importance of “Throw” and “G” Force “Throw” is the term used by vibrating screen designers denoting the distance that a vibrating screen travels during its operating motion. The term is also referred to as “stroke”. For a straight line motion screen the “throw” is the distance between the extremities of motion.The tangential force F τ is expressed in incremental form, the increment ΔF τ corresponding to the incremental tangential displacement Δδ τ is given by (4) Δ F τ = 8 δ n G 0 θ k Δ δ τ + − 1 k μ 1 − θ k Δ F n where E 0 and G 0 are the equivalent Young's and shear modulus of the two contact particles, δ τ = ∫ v τ rel dt is the tangential overlap, R 0 A novel neural network approach to modeling particles distribution

Hence, the particle dynamic behavior of a circular vibrating screen and linear vibrating screen in the normal direction is the same with the same amplitude in the normal direction. Figure 2 a shows the particles dropping from three heights (0.3, 0.301, and 0.302 m) under f = 16 Hz, and A = 4 × 10 −3 m.Impact forces from contact with the boundary wires act as impedances to the force of gravity, the only force causing the particle to fall through the opening.

3.2 Dynamic Analysis of Vibrating Screen. Since the vibrating screen is an inertial screen, during the vibration process, the force generated by the eccentric mass of the exciter is mainly driven; that is, the inertial force plays a leading role, and the spring restoring force and the damping force are negligible [].Therefore, in the dynamic analysis of the
