The boom of the stacker starts in its lowest position. The first row is deposited in the centre of the stockpile, the next rows are layered on it. In longitudinal stockpiles, the stacker usually moves in a tilting and slewing motion, in circular stockpiles the stacker moves in a circulating and luffing motion. Efficient coal mining

Stackers are a dependable and reliable means of stacking large volumes of material efficiently and uniformly. Stackers are designed to feed material onto the stockpile and to distribute it in a controlled manner. Features. High capacity stockpiling. One operator can control all system functions, as well as oversee machine status and perform ...


Larger coal stockpiles have a reduced rate of heat loss, leading to a higher risk of spontaneous combustion. 5. Stacker/Reclaimer • Stacker/ reclaimer is used to stack coal in the stock pile for future use and reclaimer is used to reclaim the same coal whenever it is required.


The design of many Power Plant stockyards allows for both stacking of imported coal whilst unloading vessels and simultaneous reclaiming of coal from the beds to the furnace. However, when unloading vessels and stacking, a typical layout would incorporate 2 x ship unloaders and these would feed material to 2 x stackers.


The high stacking throughput of the new unit allows a coal vessel of 60,000 deadweight tons to be unloaded in only three days. During this process, which typically occurs once a month, a ...
