Mobile ‘reclaim’ hopper enhances production in coal stockyard
Telestack Limited continue to excel in providing innovative
mobile coal handling solutions to its worldwide customer base.
Telestack mobile materials handling systems are built to last,
combining strength with the highest quality components available
on the market. The success derives from achieving sustainable
value for the client; using mobile bulk handling technology to
enhance operational efficiency, minimize environmental impact
and maximize flexibility.
Telestack Limited has enjoyed great success when installing
coal handling facilities throughout the globe. Most notably to
date has been the installation of a wheeled mobile reclaim
hopper which will feed onto a stacker /reclaimer conveyor belt
in Gangavaram Port, India. Currently, the customer has three
lines in the stockyard consisting of two stacker/reclaimers and
one stacker only.
However, when unloading vessels with the two unloading
cranes onto two of the lines, this only allows for one other for
either feeding the local power plant or loading trains for inland
transportation. This presents an operational ‘bottleneck’ and
reduces the operational capabilities and flexibility of the
operation. The mobile reclaim hopper is fed via two CAT 966
front end loading shovels. The machine is placed in the
downstream from any of the three lines even if the
stacker/reclaimer or stacker is operating and used to feed
these lines directly from the coal stockpiles in the stockyard.
This greatly increases operational flexibility and production,
which allows for one line to be redundant in case of routine
maintenance or failure.
The customer’s stacker/reclaimer currently reclaims the coal
at 1,500tph (tonnes per hour). However, with the CF 1015 it is
reclaiming the coal at a peak rate of 1,400tph. The two CAT
966 front end loading shovels have an average capacity of
1,000tph, which is currently achievable over a 15–20-metre load
and carry distance with 5m3 buckets (eight tonnes per load).
This increase in production shows that with minimal investment,
current stacking/reclaiming systems can greatly enhance
production capacity with this type of reclaiming hopper, without
investing in further high-equity equipment.
 
CUSTOMIZED DESIGN
The CF 1015 wheeled mobile reclaim hopper offers maximum
flexibility for the operator. It includes a wheeled bogie unit
complete with toe hitch for easy site movement via a loading
shovel. The 18m3 hopper is fed from two CAT 966s from three
sides and reaching a capacity of 1,400tph for coal. The advantage
of loading from three sides is that it means the operator can
load the machine in the narrow access areas between the
reclaim belt and the stockpiles, which allows greater flexibility
during the loading process.
Also, there is a custom upgrade of polyurethane low-friction
liners on the material transfer points (hopper, transfer feed-boot
and chute) to allow the material to flow easily without potential
blockages and bridging. The hopper also includes a 200mm
aperture grid which excludes any foreign material from mixing
with the coal. As the reclaim hopper is directly feeding the
reclaiming belt, the incline conveyor on the Telestack unit has
luffing capabilities (raise/lower) from 12–20°, which offers the
customer the flexibility to vary the discharge height, depending
on ground levels and the height of the reclaiming belt at the
certain points. The unit also includes a manual trimming chute
which allows the customer to direct the material to reduce
segregation/degradation and control the flow of material onto
the belt.
The mobility of the CF 1015 is further enhanced as it
includes a 110Kva Genset for all functions to make the unit a
complete independent unit, with optional lights to ensure 24-
hour operation.
This customized solution highlights Telestack’s aim to provide
for the specific needs of each application to ensure the
equipment is efficient and reliable to enhance the production
capabilities of any stacking/reclaiming system within a stockyard.
 
Three new contracts for ThyssenKrupp Fördertechnik at EMO
Stockyard equipment is a major component of three major new
contracts won by ThyssenKrupp Fördertechnik for the EMO
terminal in Rotterdam in the Netherlands.
In the early 1970s, PHB and Krupp delivered the first ship
unloading and stockyard equipment for the newly constructed
EMO terminal. Since then, Krupp and PHB, later PWH , today
integrated in ThyssenKrupp Fördertechnik, have designed the
entire ship unloading, shiploading, wagon loading and stockyard
equipment for the EMO terminal.
Today the terminal, located at Maasvlakte right at the
entrance to Rotterdam’s Seaport, is the largest import and
export terminal in Europe for dry bulk material with an annual
unloading capacity of 42mt (million tonnes). Continuing and
even increasing demand for coal and iron ore, in particular from
German steel mills and power plants, as well as the construction
of two new coal-fired power plants directly at Maasvlakte has
now lead to further investments for the terminal.
 
BUCKETWHEEL STACKER/RECLAIMER (KB7)
In 2009 Electrabel, Netherlands began work on the construction
of a coal-fired power station at Maasvlakte. With the EMO
terminal being in the direct vicinity of this future power station,
it was the obvious solution to use the EMO infrastructure for
feeding the power station with coal from the EMO terminal. To
handle the increased volume of coal it was decided to install a
further combined stacker/reclaimer on the EMO premises. This
machine will be the seventh bucket wheel stacker/reclaimer
(KB7) and will be a exact copy of the stacker/reclaimer No. 6
(KB6) which is the largest one of its kind in Europe (see picture
below).
During reclaiming, the material can be transported either to
the EMO terminal or to the power station. To this end, the
Three new contracts for ThyssenKrupp Fördertechnik at EMO
stockyard conveyor has been fitted with a reversible drive unit.
The upstream material flow, coming from the EMO terminal, can
either be stacked by KB7 onto the stockyard or it can instead by
sent directly to the Electrabel Power Plant. To achieve this, the
machine has been equipped with a retractable Tripper car which
either feeds the intermediate conveyor during the stacking
operation or by-passes the machine either during reclaiming or
during direct feeding to the power plant.
KB7, as well as all the other EMO stacker/reclaimers, have
been designed to mainly handle coal and iron ore. Although the
respective material properties are quite different, the machines
have been designed to reclaim and to stack each of these
materials at the same capacity. This is achieved by using variable
conveyor and bucket wheel speeds.
The cell-type bucket wheel with nine buckets and a diameter
of 9m is driven by a slow running hydraulic motor and reclaims
the material at up to 4,500tph (tonnes per hour).
During the stacking operation, up to 6,000tph of coal or iron
ore can be conveyed to the stockpiles. With a boom length of
60m, the machine is able to stack piles up to 60m wide and 24m
high.
Besides the bucket wheel, the slewing mechanism is also
driven by a slow-running hydraulic motor in order to be able to
control the slewing speed while protecting the mechanism from
peak loads.
The geometry of the bucket wheel boom and the
counterweight boom as well as those at the tie rods have been
arranged to form a parallelogram. In comparison with other
systems, this C-frame system offers the advantage of a minimum
displacement of the centre of gravity while lifting and lowering
the bucket wheel boom. This results in a more uniform
distribution of the load onto the slewing roller bearing and onto
the travel mechanism.
Due to the fact that KB7 is an exact copy of KB6, and many
of the parts and components are also identical to the other
stacker/reclaimers, which have all been supplied by TKF, spare
parts management has been kept simple. These similarities also
apply to maintenance and operation. The operation has now
been changed over from manual operation to fully automatic
mode.
 
85-TONNE GRAB UNLOADER
While KB7 is the largest stacker/reclaimer in Europe, the
unloader No. 5, together with its neighbouring cranes No. 3 and
No. 4, is the largest grab-type ship unloader in the world.
With its span of 70m, its overall construction height of 70m
and its waterside outreach of 50m, the machine is able to unload
even the largest existing coal and iron ore bulk carriers.
Apart from unloading ships the machine is able to serve an
emergency stockpile which can be situated between the hopper
installation and the landside leg.
The rope-drawn machine trolley with a working range of
102m comprises the hoisting and closing winches, each driven by
two motors of 780kW which can lift the 85-tonne load at
speeds of up to 180m/minute. By means of a grab cross-travel
mechanism, most of the movements alongside the ship during
the unloading process in a single hold can be realized without
the portal travelling.
The electrical power feeding of the equipment installed on
the machine trolley is realized by means of a power cable on a
catenary system situated below one beam of the bridge girder.
Rope system:
  •   56mm hoisting/closing rope;
  •   48mm trolley travelling rope; and
  •   48mm boom hoisting rope.
The trolley travel mechanism which is situated in the gantry
girder machine house accelerates the trolley up to a speed of
240 m/minute by means of a winch system driven by two
545kW motors.
During mooring and unmooring of ships and possibly during
the moving of the unloader from one hatch to another, as well as
in the out-of-operation position the boom will be retracted by
means of a luffing mechanism in order to avoid collision with the
superstructure of the ships. The luffing mechanism winch, which
is driven by means of two motors of 230kW is able to lift the
boom in approximately five minutes. In its top position the
boom will be secured by means of two hydraulically activated
catch hooks. In its lower position, the boom is suspended in
holding tie rods.
The mobile operator’s cabin travels independently from the
trolley on a separate track which is located under one beam of
the bridge girder, so that the crane operator can move his cabin
always into the most favourable position in order to have a good
view of the entire working area.
In order to avoid spreading forces in the structure and coping
with the rail tolerances, the landside leg has been equipped with
a pendulum mechanism which is only activated during portal
travel. While unloading, the landside leg is fixed to prevent the
structure from swinging.
The unloader travels on a double rail system at both water
and landside and is supported on 56 runner wheels with 900mm
diameter. Fourteen drives, each with 55kW, accelerate the
unloader with the total weight of over 3,000 tonnes up to
speeds of 25m/minute.
With the flexible hopper discharge mechanism, which
comprises two apron feeders and two reversible distribution
belt conveyors, it is possible to serve each one of the four quay
conveyors at full unloading capacity.
 
WAGON LOADING STATION WB 4
Increasing demand, in particular for coal for German power
stations, has resulted in the existing three wagon loading stations
being brought to the limit of their capacity. After the
procurement of wagon loading station WB 3 (successfully
commissioned by ThyssenKrupp Fördertechnik in 2006), EMO
therefore decided to install a further wagon loading station —
WB 4 — whose commercial operation is scheduled for May
2011.
WB 4 spans three parallel rail tracks and is able to serve two
of them. Above the third rail track an operator’s cabin has been
integrated in the tower structure. In addition to having an
excellent view of the loading process of WB4, it is also possible
to monitor WB3 which is in the direct neighbourhood.
The material which is received by the feeding conveyor of
approximately 180m length, which also forms part of TKF’s scope
of supply, is discharged at a height of approximately 33m into the
surge bin of 350m³. From there, it is discharged into the
weighing bin by means of hydraulically operated double-radial
gates. As soon as the preset material content of the weighing
bin has been achieved, the double-radial gates of the weighing bin
are opened to allow a constant filling of the wagon to be loaded.
During the loading process the wagons are pulled with a
constant speed by a robot train. With a two-way chute directly
installed underneath the weighing bin, both of the loading rail
tracks can be served.
Comparing capacities with WB 3, loading capacity has been
increased from 3,500tph to 4,500tph.
EMO’s decision to award TKF all three of its important
contracts represents continuity in the long-standing relationship
and demonstrates the client’s appreciation of, and satisfaction
with, TKF’s performance to date. The choice went in favour of
TKF after strong international competition. Of particular note is
the competition for the grab-type unloader, which came not only
from European companies, but also from Chinese competitors.

COMPLETE MATERIALS HANDLING SYSTEMS
Sandvik Mining and Construction’s Materials Handling business
offers all services related to bulk materials handling, including
feasibility studies, conceptual plant layouts, design, engineering,
and the entire execution of complete systems to handle coal,
ore, bauxite and other different materials — a vast range of
equipment for applications such as the following:
  •   conveying, stacking, reclaiming and blending of bulk materials;
  •   loading bulk materials into ships;unloading bulk materials from ships; and
  •   crushing, sizing and feeding of bulk materials.
This offering supports the continuous
transfer of the material in various fields of
materials handling solutions, whether as
individual machines or as complete turnkey
installations. The classical application of these
systems and machines relates to stockyard
facilities at mines, at export and import ports
and in stockyards of power stations, steel
works and processing plants. According to the
requirements of the downstream consumer,
Sandvik’s systems can reach output rates up to
more than 10,000tph (tonnes per hour).
 
COMPLETE HANDLING SYSTEMS FOR STOCKYARDS
Stockyards, either as a circular or longitudinal layout incorporating
particularly feedconveyors, stackers and reclaimers, have a central function
in the fields of materialshandling as they serve as material buffers,
reserve or blendedstorage between incoming and outgoing materials. As buffering,
composing and homogenizing performed by a stockyard can vary,
quantity as well as quality fluctuations can be balanced out with
the correctly chosen system. As the priorities for each
application and stockyard operations are different, it is necessary
to consider various questions before selecting type and size:
throughput required, characteristics of the materials to be
handled, homogenizing effect required, open or roofed storage
and importantly, the future upgrading of the storage. Sandvik
offers a complete range of products to provide customized
solutions for each customer’s specific requirements. The
equipment comprises:
  •   reclaiming technology for bucketwheel boom-type, bucketwheel bridge-type, scraper-type, drum-type units;
  •   stacking technology for the most commonly used stacking methods: chevron, windrow and coneshell
  •   combined stacking/reclaiming technology for bucket wheel or circular units
  •   conveying technology including transfer stations
  •   auxiliary equipment with hoppers, feeders, crushers, etc.
Covered storage is used where environmental aspects
require the full enclosure of the stockpiles and stacking and
reclaiming activities. It can either be arranged in the form of a
longitudinal/rectangular configuration or in a circular
configuration covered by dome-type structures.
 
STACKERS (PS SERIES)
Sandvik stackers effectively stockpile bulk materials in an efficient
and orderly manner. Stationary or traveling, borne on rails or
crawlers, they can be supplied in fixed, luffable or luffable-and slewable
boom designs, with capacities from 150 to 20 000
tonnes per hour. The choice of design depends on factors such
as the stacking method and size of the stockpile, the type of
material, the required throughput and the demand for mobility.
Tripper cars or tripper systems for transferring material from
the yard conveyor to the stacker are considered part of the
stacker.
 
RECLAIMERS (PR SERIES)
Sandvik reclaimers are designed to reclaim bulk materials from
stockpiles at mines, ports, steel plants, power stations, etc. in a
quick, efficient and orderly way (see picture on p90). They are
available in several main types, including bucket wheel, scraper
and drum-type reclaimers, and in many configurations and sizes,
with capacities from 500tph to 20,000tph and more. The choice
of design depends on factors such as the size and shape of the
stockpile, the type of material to be reclaimed, the required
reclaiming rate and the need for blending or homogenization.
 
STACKER/RECLAIMERS (PD SERIES)
Sandvik stacker/reclaimers come in two main types: bucketwheel
models for alternate stacking and reclaiming, and circular
units, which normally stack and reclaim the material alternately
but can be designed to do so simultaneously if required. The
bucketwheel models, normally supplied complete with tripper
cars, are compact and economical for longitudinal stockyards
where simultaneity is not required and where there can be large
variations in the demand for stacking and reclaiming capacity.
Standard circular units, which build a ring-shaped stockpile and
are normally housed inside a covered dome because of
environmental aspects, both continually stack the stockpile at
one end of the ring and reclaim the material simultaneously from
the other end.
 
TRANSPORTATION SYSTEMS (PC SERIES)
Sandvik has a highly skilled projects division specializing in the
design, manufacture, installation and commissioning of conveyor
systems for a full range of applications. Sandvik also upgrades
and modernizes systems and supplies a comprehensive range of
its own quality components and spare parts.

  •   the fertilizer industry;
  •   delayed coking processes in refineries; and
  •   development of environmental improvements in coal-fired
  • thermal power plants.
In the fertilizer sector PHB has, over the last few years, been
a major player in several OCP projects, from the raw materials
(phosphates and sulphur) to the final products. PHB has also
participated in prestigious international projects such as
Ma’aden.
As far as delayed coker units are concerned, PHB is proud to
have been part of projects undertaken by BP (British Petroleum
[now Beyond Petroleum]), Repsol, Aramco (Al Jubail project),
Petrobras, etc.
In the field of environmental improvements in coal fired
thermal power plants, PHB has collaborated in the development
of biomass handling facilities as well as the handling of limestone
and gypsum coming out of desulphurization processes at various
plants in Spain, Portugal, Italy, Chile, and other countries.
