Bucket-wheel Stacker/Reclaimers travel on a rail track alongside the piles of material, offering the potential to selectively stack and reclaim materials in different stockpile sections. This is carried out in two quadrants (directions) on both sides of the track. Four quadrant reclaiming is possible with units featuring tripper-trailers that can be uncoupled. Active stockpiles may be stacked and reclaimed within the traveling limits and operating radius up to the boundary zone of the storage area on the boom side of the machine. On the trailer side, a clear space, or box cut, is provided, which permits the bucket-wheel to cut into a free end face of the pile.
Wagon tipplers unload coal from railway wagons. Existing wagon tipplers no. 2 and 3 work on the principle of rotation around its axis. With rotation of the wagon tipplers coal from full wagons is unloaded into the bunkers beneath the wagon tipplers, from where the coal conveyor system transports the coal to the coal bunkers or open coal depot within TPP “Tuzla”.
Bucket Wheel Excavators (BWE) are continuous cutting machines for soft to semi hard materials like clay, sand, gravel, marl and their blending as well as lignite and hard coal. The characteristic parts of a Bucket Wheel Excavator are the cutting wheel with buckets, the wheel boom, the superstruc-ture with counterweight boom, the sub-structure, the undercarriage with crawler tracks and a transfer boom to the bench conveyor (or a connecting bridge to the loading unit). All main parts are designed to meet the demands of the project re-garding optimization, standardization and maintenance.
