Stacker Cum Reclaimer
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.
Reclaimers normally travel on a rail between stockpiles in the stockyard.
A bucket wheel reclaimer can typically move in three directions: horizontally along the rail; vertically by “luffing” its boom and rotationally by slewing its boom. Reclaimers are generally electrically powered by means of a trailing cable.
Bucket wheel reclaimers use “bucket wheels” for removing material from the pile they are reclaiming. Scraper reclaimers use a series of scrapers on a chain to reclaim the material.
The reclaimer structure can be of a number of types, including portal and bridge. Reclaimers are named according to this type, such as “Bridge reclaimer”. Portal and bridge reclaimers can both use either bucket wheels or scrapers to reclaim the product. Bridge type reclaimers blend the stacked product as it is reclaimed.
Stacker Cum Reclaimer is stacker & reclaimer combined in one machine with bucket wheel boom.
The minimization of the total number of machines on a stockyard as well as the reduction of conveyors and trails constitute a great advantage of the stacker/reclaimer.
