An experimentally validated rubber shear spring model for vibrating
Dry screening of viscous and fine-grained minerals is an urgent problem to be solved in processing coal ore, and iron or gold deposited rocks, etc [1], [2].However, conventional screening equipment (linear vibrating or circular vibrating screens) frequently encounter the problem of rapid blockage of the screen's apertures, which reduces screening efficiency [3], [4].
