The vibrating screen do forced vibration when it is under highintensity loads. It is prone to fatigue failure. The key components of the vibrating screen are screen box, because of its complex structure and shape; the traditional design methods cannot calculate its stress

Atheoretical Rigid Body Model Of Vibrating Screenfor

Meanwhile, the mining vibrating screen amplitudes change with the spring failures. Therefore, six types of spring failure are selected for simulations, and the results indicate that the spring failures lead to an amplitude change for the four elastic support points in the x, y, and z directions, where the changes depend on certain spring failures. Hence, the key to spring failure diagnosis lies in obtaining the …
