Maximizing Your Screening Efficiency Aggregates ...

May 10, 2021  Screening efficiency measures how much of the desired aggregate is accurately separated during the screening process. For example, if your screens are operating at 80% efficiency, that means 80% of the desired aggregate size passes through the screens while 20% does not. Efficiency should be as close to 100% as possible, but keep in mind that ...
