Spring failure is one of the critical causes of the structural damage and low screening efficiency of mining vibrating screens. Therefore, spring failure diagnosis is necessary to prompt maintenance for the safety and reliability of mining vibrating screens. In this paper, a spring failure diagnosis approach is developed. A finite element model of …

overly optimistic. The biggest assumptions are the screen will have the correct rpm and stroke length for the given application. Also, there are some obvious errors in the published tables. Most manufacturers use a modified version of the VSMA (Vibrating Screen Manufactures Association) formula to determine screen capacity. The twelve factors

The composite vibrating screen can be realized using two pairs of excitation motors with different frequencies; the rotational speed ratio of the high-frequency excitation motor and low-frequency excitation motor is 2:1, and the two pairs of excitation motors are distributed symmetrically around the center of mass.

Anthem Screens are typically used in fine and coarse screening applications or for operators requiring a scalping stage, which removes oversized materials before the …

The material velocity of a circular vibrating screen can be calculated from the corrected theoretical speed of the product formula written below. Example: Determine the material velocity of a screen vibrated at 900 RPM with a 12 mm stroke and 20° degree inclination angle. To calculate the bed depth of the material, the following formula is used.
