loans: “We will move forward from both the
health crisis and the economic crisis,” he said
Thursday during a press conference in Mexico
City. “I am [an] optimist.”
Overall industrial output dropped sharply
in April, down 25.1% from March with
manufacturing and construction down by
20.5% and 32.8% respectively. As of early
June, however, it was reported by the Mexican
Institute of Social Security (IMSS) that almost
24 000 essential construction, mining and
automotive companies had resumed activity.
In order to re-open, these businesses had to
apply to the IMSS and comply to a series of
mandatory health regulations and be subject to
inspections.

Richmond plant, Lafarge Canada Inc.
Lafarge Canada’s low carbon fuel system
represents a US$28 million CAD investment
in long term sustainability at the Richmond
cement plant. The facility includes a storage
hall with three hoppers and conveyor
systems to transfer to the fuels to the kiln and
pre-heater tower. The new system has allowed
for a daily fossil fuel substitution rate as high
as 70%, thus significantly reducing the plant’s
GHG emissions.
The CO
2
ment pilot project with Svante and
Total has been launched, and aims to capture
the flue gas from the Richmond cement plant
and create a one tpd CO
2
stream. Lafarge
intends to reinvest the CO
2
in its building
materials, primarily concrete and aggregates.
Lafarge also intends to work with emerging
technology companies that are using CO
2
as a
feedstock.

Hidalgo Cement Plant, CYCNA, Cooperativa La
Cruz Azul, S.C.L.
The Cooperativa La Cruz Azul is establishing a
new cement production line in Hidalgo, Mexico.
The Hidalgo plant has a production capacity
of 3 million tpy of cement. The new line, as well
as all existing kiln lines, will be supplied with
ground pet coke from the LOESCHE mill in
future.
In addition to the new mill with a capacity
of 50 – 65 tph, LOESCHE will also supply
process gas filters, mill fans, inertisation units,
explosion flaps, cyclone separators, conveyor
augers and drag chain conveyors as well as
the complete electrotechnical equipment.
The scope of supply additionally includes the
complete detailed engineering for steel and
concrete construction.
The customer’s cement plant is
located 2300 m above sea level in the
mountains of Mexico. This altitude was taken
into account when sizing and selecting the
aggregates to be supplied, especially when
selecting the motors and electrical system.
The equipment has already been fully
dispatched.
Lagunas plant, Oaxaca province, CYCNA,
Cooperativa La Cruz Azul, S.C.L.
Cooperativa La Cruz Azul has selected
thyssenkrupp Industrial Solutions for the
technological update of its plants in Lagunas,
Oaxaca and Cruz Azul, Hidalgo in Mexico.
Both plants selected the same main polysius
equipment for the pyro-processing line
comprising dopol90 preheater, polro kiln,
polytrack clinker cooler, alternative fuel dosing,
prepol SC burning equipment, raw meal silo
and utilities. The project’s scope is EPC
(engineering, procurement and construction).
The new clinker lines will allow Cruz Azul to
produce more efficiently and sustainably with
the use of state-of-the-art technology.
Additionally, in 2018, Loesche sold two coal
grinding plants of type LM 41.4 D, one of the
largest coal mill types for grinding petcoke, to
the Cooperativa La Cruz Azul group. These
coal mills are to be used in two more of the
client’s plants: in the Hidalgo province 80 km
north of Mexico City, and in the Lagunas plant
in the Oaxaca province in southern Mexico.
Cooperativa La Cruz Azul is establishing a new
cement production line in each of the plants.
Planta Aguascalientes, CYCNA
Fives supplied the oil system for K1 and K2
precalciners.
Veracruz cement plant, LafargeHolcim Orizaba
The customer was looking for a solution to aid
a drastic shift in fuel consumption. In order to
reduce the plant’s average yearly energy costs,
the target was set to reduce the traditional
fuel consumption of coal to AFR (fluff fuel
such as shredded plastics and cardboard).
Opting for these new fuels meant that the
plant’s conveying system had to be drastically
redesigned.
AFR materials, such as tiny plastic particles,
need to be conveyed in a totally sealed system,
as wind or any rough weather conditions
can blow these particles away and affect the
immediate environment. Indeed, the product
density is very low (0.3 – 0.5 t/m
