Cartagena and Rioclaro Plant, Argos
Argos established an alternative fuel supply
line of coprocessing in the facilities of Argos’
Cartagena and Rioclaro plants.
The company was able to manage and
consume all types of alternative fuels with
a good result. In 2019 in Colombia, Argos
was able to co-process 8000 t of waste,
including tyres, with an increase of 75% of
the substitution of fossil fuels, in comparison
with 2018. Those results are in line with
Argos’ Environmental Strategy and the circular
economy.
An investment of more than US$78 million
was made at the Rioclaro Plant for the
assembly of the new production line capable
of producing 450 000 tpy of calcined clay.
With this investment, Argos has begun to
manufacture and distribute Green Cement.
In this process, the use of traditional clinker
(base material for cement) is reduced thanks
to the incorporation of calcined clays (artificial
pozzolan).
This innovative product makes it a more
environmentally friendly cement, since during
the production process carbon dioxide
emissions are reduced up to 38% and
energy consumption is reduced by 30%, in
comparison to the industry standard.
Bricking Solutions also supplied a Universal
Safety Cage to the plant, for kilns ranging
from 4 m to 6 m.
Sonsón, Empresa Colombiana de Cementos
(Ecocementos)
Empresa Colombiana de Cementos
(Ecocementos), a company held by
Cementos Molins and Corona, has confirmed
the start of production in its new cement
plant in the municipality of Sonsón, Antioquia,
Colombia. The installation has represented an
investment of more than a billion Colombian
pesos (approximately US$380 million), and
it will reach a production capacity of up to
1 500 000 tpy of cement.
Chile
Punta Arenas, Melon SA
Melon SA awarded Bedeschi with a contract
for the supply of a new Eco-Hopper to be
operated on the austral port of Punta Arenas,
Chile.
The Eco-Hopper is designed for direct
unloading of clinker to trucks at a rate of
600 tph and is designed to work with 12 m
3
grabs. The machine is equipped with pulse-jet
bag filters with high filtration capacity and
performance and with low compressed air
consumption: an economical and flexible
solution to satisfy the stringent environmental
standards required.
The Eco-Hopper is designed with a special
support structure that allows a solid anchoring
of the hopper to the pier structures during
unloading operations, but at the same time it
allows the machine to be moved by means of
SPMT when not in use. This configuration is
made necessary by the multi-purpose nature
of the Punta Arenas port and due to structural
limitations of the existing pier. These operational
constraints have forced Bedeschi engineers
to find a solution in terms of flexibility of use,
weight limitation and structural strength.
The Eco-Hopper will be delivered complete
with electrical plant and control system and will
be finally assembled directly on Punta Arenas.
