Screen Efficiency and Screen Size Adjustments

AggFlow can automatically calculate the required screen size for each application. For a fixed screen size, it will also calculate the efficiency of each screen deck. The efficiency calculations can be overwritten with a fixed value.

The four decision points for setting screen efficiency and screen size adjustments are shown in this matrix:

Using Calculated Efficiency

  • Increases or decreases the screen size as needed to achieve the maximum deck efficiency.
  • After reaching maximum screen size, it continues to lower deck efficiency.
  • Red flags appear if deck efficiency lowers to 70% and there is still not enough available area.
  • Raises or lowers deck efficiency as needed to match the fixed screen size.
  • Red flags appear if deck efficiency lowers to 70% and there is still not enough available area.

Using Fixed Efficiency

  • Increases or decreases the screen size as needed to achieve the fixed deck efficiency.
  • Red flags appear if a screen size cannot be found that will meet the specified deck efficiencies.
  • Will not alter screen size or deck efficiencies.
  • Red flags appear if there is not enough area to achieve the specified deck efficiency.
