TENOVA is a worldwide supplier of advanced technologies, products and engineering services
for the iron & steel and mining industries.
Our Competence in Scraper Reclaiming Technology
n Decades of experience in building scraper reclaimers
n Proven and reliable equipment solutions based on profound know-how
n Excellent track record with more than 300 successful reference projects
n Vast expertise in handling bulk materials such as coal, lignite, iron ore, bauxite, zinc ore, kimberlite, potash,
phosphate, rock salt, urea, pet coke, slag, clinker, gypsum or limestone
n Strong global network for local technical support and site services
Our Product Portfolio
Machines:
n Bridge-type scraper reclaimers
n Portal and semi-portal scraper reclaimers
n Cantilever scraper reclaimers
n Combined stackers/scraper reclaimers
n Circular blending beds with bridge-type scraper
reclaimers
n Circular storages with cantilever, semi-portal or
full-portal scraper reclaimers
Technical features:
n Portal Reclaimers: Rail gauges up to 70 m and capacities up to 6,000 t/h
n Bridge Reclaimers:Rail gauges up to 60 m and capacities up to 2,500 t/h
n Circular Storages: Storage capacities up to 350,000 m³ with diameters up to 150 m
n Blending Beds:
With up to 400 layers blending ratios of up to 10:1
Buffer Storages
Twin boom portal reclaimers are high capacity machines
usually employed in operations where high volumes of
bulk materials are being handled.
The featured scraper reclaimer (fig. 4) is equipped with a
drag trough for each reclaimer boom and has an average
reclaiming capacity exceeding 3,000 t/h. The machine
has a rail gauge of 52 m and serves a coal storage with a
width of 45 m and a length of 435 m. It is part of a turnkey project including a stacker, a conveyor system and a
railcar loading station.
In a German lignite mine two portal scraper reclaimers
work at a storage (fig. 2) serving as a 400,000 tons buffer
between an open-pit mine operation and a 2 x 900 MW
power plant. A fully automated stacking method combined
with side reclaiming ensures for this application best blending results and continuously high lignite quality for power
generation.
Blending Beds
The reclaiming capacity of each portal scraper is 2,400 t/h
and the rail gauge 62.5 m. These machines are worldwide the first portal scraper reclaimers to be employed in
a buffer and blending stockyard for lignite.
For more than 20 years the circular buffer storage featured
under fig. 3 is handling reliably abrasive slag.
Feeding of the storage as per the coneshell method is
being done by a slewing stacker with a capacity of 1,000
t/h while reclaiming is being achieved from the inner
slope of the pile by a cantilever reclaimer. The scraper
blades guide the slag to the central chute being the link
between scraper reclaimer and outgoing conveyor.
If equipped with ring walls circular storages offer a maximum of storage capacity on a minimized space.
Be it the optimal homogenizing of different qualities inside
a pile or the ensuring of uniform grain size distribution for
further processing - with Tenova TAKRAF´s bridge type
scraper reclaimers optimal blending results can be achieved.
The material is being reclaimed from the front side of
the pile where an almost full-pile facing harrow loosens
material from all pile sections which then smoothly slides
to the pile bottom into the scraper shovels.
The featured machine (fig. 7) is operating in a steel plant
and handling abrasive iron ore. Its reclaiming capacity is
600 t/h and the rail gauge 35 m.
Twin harrow bridge reclaimers operating between two piles
in longitudinal blending beds work in both directions.
While the first pile is being stacked, the scraper reclaimer
empties the second pile and vice versa. The harrows are
driven hydraulically.
The shown machine (fig. 6) has a reclaiming capacity of
1,500 t/h, a rail gauge of 35 m and blends ROM Coal
before feeding into a coal washery.
The circular blending bed for ROM Coal shown in photo 5
below has a stacking capacity of 3,300 t/h and reclaims
2,300 t/h. The rail diameter is 120 m.
A conveyor feeds the coal through a chute on top of the
central column to the slewing and luffing stacker for piling
in layers using the chevcon method. The stacker operates
360° in an endless mode. The bridge type scraper reclaimer follows the stacker, as well in a 360° endless mode.
This arrangement combines excellent homogenizing
capability with easy continuous stockpile management
without end cones.
Tenova TAKRAF offers a variety of solutions ranging from single machines to integrated systems and complete
turn-key projects.
