Material Handling in Port Areas
Harbour Equipment
With a proven range of loading and
unloading equipment for ships and
barges, FLSmidth® provides
comprehensive solutions for both
seaport and inner harbour handling
facilities, including state-of-the-art
safety and environmental devices.
FLSmidth port handling equipment
allows faster loading and unloading
of ships up to cape size vessels.
Custom-designed components such a
telescopic loading chutes ensure
optimal loading of the cargo holds.
FLSmidth loading and
unloading facilities:
• Shiploaders up to 16,000 t/h
• Ship Unloader
• Continuous, screw, or
bucket chain type
• Grab Unloader
• Barge loaders and unloaders
Pneumatic Unloader
Based on the experience of FLSmidth’s
Kovako® brand, new standard models
have been developed that represent
common combinations of capacities
vs. ships sizes and platforms (e.g.
trailer, gantry and skid mounted
units). As a result, FLSmidth can now
offer standard unloader models from
road mobile units with a nominal
capacity of 170 tph for 5.000 DWT
ships to gantry mounted unloaders of
450 tph nominal capacity for 40.000
DWT ships.
KOCH Pipe Conveyor®
FLSmidth Pipe Conveyors, using the
KOCH® technology, offer forwardlooking conveying solutions for all
types of bulk materials, from cement
to coal, from phosphate granulates to
wood chips. With their special design,
they ensure high availability and low
investment costs as well as a perfect
protection for both material and
environment.
Furthermore, we deliver advanced
expertise in fully enclosed pipe
conveyors in both, in-plant and
overland applications and are
considered the worldwide market
leader with hundreds of
installations,including one of the
world’s longest KOCH Pipe Conveyor,
spanning 8.2 km in Peru
KOCH Pipe Conveyors – the
smarter way of transporting
bulk solids:
• Dust and spillage free
transportation
• Low noise emissions
• Inclines up to 30°
• Horizontal and vertical curves
with minimal radii of up to 45
metres
• Axial spacings of 8 km and more
without transfer stations
• Simultaneous conveying of
different materials in both
directions
• Multiple feed and discharge
points
• Low power consumption

Petcoke Storage and
Handling
FLSmidth offers a complete range
from A to Z for storage and handling
of petcoke in smelters, which
comprise:
Unloading facilities for all types of
transportation means, whether by
barge or ship, railcar, truck Loading of
petcoke into silo or open trucks,
railcars or ship and barges. Overland
transportation using advanced pipe
conveyor technology or standard belt
conveyor systems. All types of in-plant
transportation e.g. by conventional
conveying, transportation by drag
chain or pneumatic conveying.
Various storage systems, such as:
• Steel silo for smaller volume
requirements
• Concrete silos
• Enclosed storage hall using
standard machines, e.g.
• Linear stacking with semi-portal
reclaimer or side-reclaimer
• Circular stacker/reclaimer
system (with/without blending)
• Open storage system with types
of linear or circular arrangements
Using the material handling expertise,
FLSmidth can offer complete
packages including all secondary and
auxiliary systems, such as explosion
protection/area classification, fire
detection and fire fighting or dust
suppression.

Primary Alumina Storage & Handling
• Feeding of alumina silo by
pipe conveyor or airlift
• Anti-segregation filling and
discharge equipment
• Different discharge systems
available to ensure
• Absolutely uniform
withdrawal of alumina
• Very even lowering of
material level inside the silo
during discharge
• Easy arrangement of the silo
bottom
• Low air (blower) requirement
• Feeding of alumina to
different transport systems
according to distance of port
to smelter (e.g. truck filling
station)
Minimized Dead Stock
Truck Filling Station
Using the Möller® technology,
FLSmidth offers engineering and
installation for all different silo types
which the bulk handling market asks
for. The range of know-how starts
with small pre hoppers and ends with
large capacity silos with a capacity of
85.000 tons and more if necessary.
Special distribution systems on top
and inside of silos ensure low
separation of finest particles (antisegregation) during silo feeding
processes. For minimizing energy
consumption the air slide systems for
reclaiming/discharge are designed
with different aeration areas which
are only fluidised one after the other.
Reliable flow control valves at the silo
discharge are followed by air slide or
other conveying systems.

Material Handling in Smelter Areas
Möller Turbuflow® Dense
Phase Conveying
Wherever feasible, FLSmidth designs
pressure vessel conveying systems
incorporating the patented Möller
Turbuflow® pipe which operates at
low velocities and high material/air
rates, resulting in low energy consumption. This kind of low velocity
dense phase conveying system also
means significantly lower levels of
wear and tear, avoiding frequent
disruptive and costly maintenance
work.
Turbuflow dense phase conveying
systems have been on the market for
over 20 years. The principle is a
conveying pipe with an inner bypass
pipe. This ingenious but simple design
prevents bulk and air separation
during pneumatic conveying.
If a plug forms, pressure loss in the
conveying line will be greater at that
point. This causes more conveying gas
to flow into the inner bypass pipe.
However, at the next opening in the
bypass pipe the gas will re-enter the
conveying pipe. Upon release of the
conveying gas, the bulk lump or clot
becomes fluidised by local turbulences. This immediately reduces flow
resistance. The bulk is thus conveyed
compactly, slowly and highly efficiently without any danger of pipe
blockages. This process is self-regulating and does not require any control
equipment. The Turbuflow conveying
system can even be restarted when
the pipe is full. Due to continuous and
intensive mixing, high bulk to air
ratios will be achieved at low conveying velocities.
FLSmidth Möller also designs pressure
vessel systems with standard pipes
and the decision as to which type of
pipe to use will depend on the
transport system.

Various designs of Möller Super Feeding
System (SFS) pipe DN 100 on top of the
electrolysis cell
Möller Direct Pot Feeding System installed at DUBAL
Möller direct pot feeding is an
innovative system that ensures
constant and reliable feeding of
secondary alumina oxide to the
electrolyte cells’ ore bunkers. This
smooth working transport system
combines the Möller Turbuflow or
Möller Fluidflow® transport system
from a storage silo to intermediate
bins at the electrolyte cells and the
Möller Fluidflow pipe air slide feeding
system directly to each of the
electrolyte cells. The Turbuflow dense
phase feeding and the Fluidflow pipe
air slide are approved systems that
preserve particle size distribution and
the flowability of the alumina. Low
conveying velocities preserve particle
size distribution and the flowability of
the secondary alumina while
minimising scaling effects. Separation
of the main conveying air volume in
the intermediate bin avoids feeding
secondary alumina from intermediate
bins via point feeders into the ore
bunker of the electrolytic cell.
