Application of an SMA Spring for Vibration Screen Control
2018-2-23 dynamic characteristics of a resonance vibration screen is proposed in this paper. These springs change spring constant as a result of temperature changes. Thus it is possible to change their resonance frequency in real time. In the paper a mathematical model of a controlled SMA spring was formulated and its parameters were identified.

Title: Coupled mode parametric resonance in a
2013-8-21 Abstract: We consider a simple dynamic model of the vibrating screen operating in the parametric resonance (PR) mode. This model was used in the course of designing and setting of such a screen in LPMC. The PR-based screen compares favorably with conventional types of such machines, where the transverse oscillations are excited directly.

SCREENING ON A SCREEN WITH A VIBRATING SIEVE
2003-11-17 The screens with vibrating sieves are designed first of all for screening of fine and very fine granular materials. They are characterized by relatively high dynamic factors. That is why in these machines layers on the sieve are well segregated and high screening efficiency is achieved. The screens with vibrating sieves are characterized
