This screen is used in almost every coal industry application, particularly in raw coal/deslime and drain/rinse operations. It increases processed tonnage 30% to 40% over the same footprint of a conventional type screen. The operating principle of the "banana" screen is based on maintaining a thin bed of material from the feed to discharge end.

What is a Vibrating Screen? Vibrating Screens are machines used to separate aggregates by particle size by means of an exciting force applied to the machine. The vibration lifts the material, causing it to stratify, allowing the smaller material to move from the top of the depth of material to the bottom of the material, thus exposing them to ...
