BMPE banana, or multi-slope, screens enable higher throughputs than equivalent horizontal screens when used in most sizing applications. These screens generate high material travel velocities on the upper deck slopes, which minimize the bed depth generated at the feed end of the screens. This facilitates the passage of fines through the bed.

These screens are available in single- or double-deck configurations, and the number and angle of the deck slopes are designed to suit specific process requirements. They are equipped with either vibrator motor or geared exciter drives.
