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

In practice, the stroke used in a horizontal screen is 7 – 20 mm. A small stroke can be used when screening with a small hole size. Because of mixing and separation, a large stroke is recommended. Stroke is defined by the swinging mass and the flywheel moment of the vibration unit. Rotation speed has no visible effect on the stroke.

One of the most important things to check on a periodic basis is the shape of the screen's vibratory motion. In Figure 1, one can see and verify the shape of the vibratory motion: circular (A), elliptical (B) or even linear (C). It is also possible to assess the amplitude of motion, as provided in Figure 2. Let's examine a few concepts ...

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.
The Tema Isenmann Stroke Gauge is used to measure the stroke (2 x amplitude) generated by a linear motion or circular motion vibrating screen. It is a quick method to check that the screen is operating within manufacturing limits. 1.
