Screen Efficiency Calculator: Free tool for calculating purity and yield

,
, RHEWUM GmbH

Test how the selection of the screen cuts of your screening machine affects the results of your screening process. The new RHEWUM Screen Efficiency Calculator determines the respective purity and yield quickly and easily – without irritating formulas.

Every producer aims to extract the greatest possible quantity of his product from the feed quantity without sacrificing the high level of quality. So in the ideal case yield and purity should both be 100 percent. But in practice, this is not technically possible and therefore testing is required to choose the right screen cut for your screening machine in order to extract a product with high yield and at the same maintaining the required purity.

The RHEWUM Screen Efficiency Calculator uses the grain size distribution of your feed material, the chosen screen cuts and also the efficiency of the used screening machine to calculate not only the yield and purity, but also the massflow of the different fractions and to show you the amount and percentage of off-spec particles in the coarse fractions. In addition, the cumulative density (passage) as well as the density distribution are graphically displayed and colored to facilitate interpretation.

To get started, choose one of our templates or enter your individual feed grain distribution manually. Tip: Use the SizeChecker in our RHEWUM app for a fast and free analysis of your feed material. By adding or deleting screen cuts or by adjusting the screen efficiency and the shift, you can monitor the effect on the screen results in real-time.
