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.

The preparation plant was constructed to a height of 150 feet or 10 stories. The Coal Wash Cycle Raw coal travels out of Beckley's 2,600-ft mine slope on a 3,000 tph 60-inch belt and can either be sent up to a 7,800-ton raw coal silo or bypassed to emergency ground storage at the transfer building.
