The central function of stockyards in the field of bulk materials handling lies in the buffering, blending and storage between incoming and outgoing materials. The stockyards for mines, power plants, beneficiation plants, ports and terminals are developed in a circular or longitudinal layout incorporating feed conveyors, stackers and reclaimers.
Reclaimer is a large machine used in stockyard system applications. A reclaimer's function is to recover bulk material such as coal, ores and etc. from a stockpile. Reclaimers are volumetric machines and are rated in cubic meters per hour (m3/h) for capacity, which is often converted to tonnes per hour (tph) based on the average bulk density of the material being reclaimed.
