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. A stacker is a large machine used in stockyard system. Its function is to pile bulk material such as coal, limestone, ores and etc. on to a stockpile.
Linear Longitudinal Stacker
Stackers are nominally rated for capacity in tones per hour (tph). They normally travel on a rail between stockpiles in the stockyard. A stacker can usually move in at least two directions:
