In the mining vibrating screen's working process, the support spring often fails due to alternating loads and a poor working environment. The six-degrees-of-freedom simplified rigid body dynamic model is established to obtain the vibration response of the mining vibrating screen with a faulty single-group spring and is verified using the …

"A vibrating motor imparts both linear and vertical motion to a deck or screen surface, causing particles to move across the screen. As these particles encounter the openings in the screen mesh, smaller particles pass through, while larger ones are retained." The applications of vibrating screens are diverse, spanning various industries.
