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 the screening surface.

Pre-sized raw coal (-50 x 0 mm) is mixed with water and passed over a deslime screen to remove the fine material i.e. below 0.5 mm or 1.0 mm in size. The undersize material passes to the fines treatment circuit(s) and the oversize 'deslimed coal' is mixed with the correct medium and pumped to a dense medium cyclone by the cyclone feed sump.

In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm.
