For particle sizes of 0.5 and 0.6 mm, efficiency increases with swing declination angle first for ψ less than 2.27°, but decreases after this point. For large particles, swing declination angle yields highest screening efficiency at ψ = 1.62°, however, the efficiency decreases at ψ > 1.62°.
An efficiency of 99% will equate to a significant loss of capacity. Efficiency is the ratio of undersize material in the feed that actually passes from the media to the undersize material that should pass from the media. This ratio is desired to be , however this is not possible due to the factors affecting the process.

Limitations of the high frequency vibrating screen are that the fine screens are very fragile and are susceptible to becoming blocked very easily. Over time the separation efficiency will drop and the screen will need to be replaced.[5] An alternative to the high frequency vibrating screens is the rotary sifter.
D = Percentage of material undersized; E = Efficiency factor (typically 90-95%) F = Basic capacity factor (typically 1) Example Solve: Let's consider a vibrating screen with a width of 2 meters, a length of 3 meters, a feed moisture content of 5%, material undersized by 10%, efficiency factor of 90%, and a basic capacity factor of 1.
Under the same vibration parameters, the transportation capacity of the composite vibrating screen material was stronger, and its same-time processing volume was 1.61 times that of the linear vibrations; the screening efficiency of composite vibrating screens was 93.75%, while that of the linear vibrating screens was 90.7%, an increase of 3.05%.
The screening efficiency can be calculated by the lower ore screen: E=β (α-θ)/α (β-θ)*. α——The content of the particle size smaller than the sieve size in the raw material; β——The content of the particle size smaller than the sieve size in the product under the sieve; θ——The content of particles smaller than the sieve ...
