The calciner burners with a thermal capacity of
35 MW each are designed for 100% natural gas
firing.
Atomstroykompleks Cement, Russia
To fire solid secondary fuel in the rotary kiln,
Unitherm supplied a combined M.A.S./3/EG.X
burner for the firing of natural gas and solid
secondary fuel. Additional equipment included a
new primary air fan, heat resistant lining, flame
monitoring and an ignition burner.
Cesla plant, HeidelbergCement Russia
To start the operation of natural gas, Cesla
purchased a natural gas valve train with burner
management system for the existing Unitherm
M.A.S. burner.
Greenfield cement project, ASK Cement
Russian construction company, ASK Cement,
is building a cement plant on a green field near
Yekaterinburg in the Ural region.
AUMUND Fördertechnik GmbH is involved
in the implementation of this greenfield project,
currently the only one of its kind in Russia.
Greenfield projects like this one at ASK Cement
are rare, as new cement lines are usually only
built adjacent to existing plants.
AUMUND developed the concept for the
complete clinker conveying package at the plant,
together with ASK Cement and its long-time
engineering partner, the Sibniiproject Cement
Design Institute in Novosibirsk.
The concept comprises transportation of clinker
from the kiln to the clinker silo, which has five
discharge channels, as well as onward conveying
to the cement mills.
AUMUND is supplying Pan Conveyors type
KZB and type KZB-Q (with baffles), Bucket
Apron Conveyors type BZB, Clinker Silo
Discharge Gates type SDG and various chutes.
Intercem has also ordered AUMUND Chain
Bucket Elevators type BWZ for mill circulation
and AUMUND Belt Bucket Elevators type BWG-L
for cement silo feeding for the project. Delivery of
the equipment is planned for the end of the first
quarter of 2020.
Krasnoyarsk Cement Plant, Sibirsky Cement
Due to more rigorous emission regulations, kiln
line no. 5 in Krasnoyarsk Cement Plant was
modernised from a direct fired ball mill – burner
system to an indirect fired system with the
following modifications:
f
Coal dust collection filter.
f
Modification of the existing intermediate coal
dust hopper to coal dust silos.
f
Coal dosing system with pneumatic
conveying.
f
KHD PYROJET kiln burner system with new
burner carriage from KHD.
f
KHD Failsafe Burner Management System
with proprietary KHD control programme.
f
Startup firing system with proprietary KHD
valve train for diesel.
f
KHD Kiln outlet with KHD kiln sealing system.
f
Kiln inlet gas analyser.
The re-starting of the kiln system followed the
schedule and stable production was achieved
within a short time. The operation results showed
increased production capacity (+3%), reduced
heat demand (-1,3%) and reduced NO
x
content in
waste gas (-51.2%).
Pikalevsky Cement enterprise
Eurocement Group Holding has
completed a large-scale investment at the
Pikalevsky Cement enterprise, under the
agreement on socio-economic cooperation with
the government of the Leningrad region.
A modernisation of the grinding department was
carried out, which made it possible to improve
the quality of products, increase the stability of its
characteristics, and expand the range as a result
of high quality and additional cements. Investment
in the project amounted to RUB150 million.
The upgraded grinding department uses
equipment from leading Western manufacturers:
KHD, Aumund, and Siemens. The plant
employees have mastered the skill of working with
new equipment and apply the best practices in
production.
Modernisation was carried out without
stopping the existing lines in order to meet the
needs of the market in the current construction
season.
Sebryakovcement JSC
Sebryakovcement JSC placed an order with
IBAU Hamburg for the engineering of four new
cement silos with inverted cones, including bulk
loading into railway wagons and trucks.
Serbia
Titan Cementara Kosjeric d.o.o.
Bricking Solutions supplied a 20 in. wide
by 110 ft long Hydraulic Conveyor to
Titan Cementara Kosjeric d.o.o.
The conveyor has a 907 kg capacity at 45 m
per minute and transports refractory and materials
in and out of the kiln.
The system is designed with heavy-duty
aluminium for sections that are as light as 16 kg
(35 lbs), which allows for easy handling. This,
paired with the conveyor’s modular design,
ensures transport and setup is fast and easy.
