Combination bucket wheel stackers/reclaimers are the most commonly used in coal yards. Mobile systems and rail-mounted or tunnel reclaim systems, while operating concurrently, can create a two-product blend on the yard belt or tunnel belt within an accuracy of 5% to 10%.
Generally, at import terminals stacker/reclaimers are used. These machines combine the two functions of stacking and reclaiming into a single unit. Consequently one of the two functions can be fulfilled at a time. Figure 2 shows a bucket wheel stacker/reclaimer during stacking of coal. For reclaiming, the bucket wheel, at
A 3D volume rate control method and apparatus ( 10 ) for a slewing bucket-wheel stockpile reclaimer 16 is described. The apparatus ( 10 ) comprises four 3D image sensors ( 12 ) mounted adjacent a bucket-wheel ( 14 ) of the (reclaimer 16 ), which are adapted to provide 3D images of a stockpile bench face. The apparatus includes a data processor ( 20 ) for (i) processing the
Cross travel seeks to control the reclaimer digging rate by traversing the face of a stockpile. During this upgrade, an opportunity arose to improve the reclaimer digging control scheme. The existing digging control scheme adjusted the reclaimer cross travel speed, based on a theoretical stockpile model and bucket wheel current feedback loop.
In this paper, a novel approach for online design of optimal control systems applied to the bulk resumption process by bucket wheel reclaimer (BWR) is presented.

It is mainly used in power sector, metallurgy, building material and chemical industry for the coal and minerals loading and discharging at the stock ground.
As a bucket-wheel stacker reclaimer, shown in Fig. 1, combines stacking, reclaiming, and transporting with the belt conveyor system, it has advantages
Jun 28, 2019 The other bucket wheel reclaimers, because boom can be short because of the operates with boom positioned at right be supplied as dual-purpose (stacker-. the design and application of these machines are also considered in response to the changing mining Bucket wheel reclaimers and stackers have proved.
Basic iReclaimer control function to monitor the depth of bucket cuts into the stockpile. Based on the iDRR measurement on both sides of the reclaiming wheel, the cutting depth is monitored and can be used for optimizing reclaimer stepping distances to increase performance.
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.
Process Control System PCS7 cess descr ipt on 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 SIS(directions) on both sides of the track. Four-quadrant
Bucket wheel reclaimers play an integral role in the iron ore sector. They are also vulnerable to contamination from dust and other particulates that cause problems to their functionality.
Stacker / reclaimer automation Reclaiming benefits Complex piles can be reclaimed, without manual intervention, taking into consideration variable bench heights, gaps in piles and changes in bench width. The predictive slew control means The slew speed can be adapted before changes in the bench can be seen in the bucket wheel power/torque
