#### Vibrating Screen Efficiency Calculations MEKA MEKA

Screening efficiency is the ratio of undersize material in the feed that actually passes from the screening media to the undersize material that should pass from the screening media. This ratio is desired to be 100%, however this is not possible due to the factors affecting the screening process. Crushing, Screening and Washing Plants

Screen efficiency is obtained using different equations, depending on whether your product is the oversize or undersize fraction from the screen. The following information is required to calculate the two screen efficiencies;-Qms(f) = Mass flow rate of solid feed. Qms(o) = Mass flow rate of solid in the screen

#### Vibratory Screens McLanahan

Screening can very easily be viewed as the most important operation in the processing plant. If the screen is only operating at 75% efficiency, then 25% of the desired product is going somewhere else. The performance of a screen is affected by four variables: eccentric throw, frequency (rpm), angle of adjustment and throw direction.

degree of rags, wipes, stringy material, and organic matter. A washer and compactor, either integral to the screen or standalone, must be used with fine screens. If the fine-screening facilities remove solids equal to or less than 3 mm (1/8 in.), then it is a common practice to provide coarse screening before fine screening.

Maximizes wetted area.

#### Screening Considerations A Guide to Selection

The Step Screen has the highest hydraulic capacity of any fine screen due to its larger open surface area when compared to any other Fine Screen technology. Step Screens are available with either 3mm or 2mm thick movable and 3mm or 2mm fixed lamellas. For the 2mm option, the open surface area for a clean screen is 75% (3mm thick lamellas = 60%).

#### Conservation screening curves to compare efficiency

This paper describes a simplified methodology for comparing supply- and demand-side resources. The screening curve approach supplements with load shape information the data contained in a supply curve of conserved energy. In addition, it contains information on competing supply technologies, such as annualized capital costs, variable costs and cost/kWh delivered.
