Maximizing Screening Efficiency
Factors That Effect Screen Efficiency? • Feed Rate Feed rate affects bed depth. ‒Before a particle can be screened, it has to get to the deck. Thin bed depth can be as bad as thick. ‒A bounding particle is not seeing much of the deck either. Increasing feed rate is not always bad.
