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.
