CEMENT PLANT 2500 TO/DAY
Offer number
0130 Complete used
cement production line
with 2500 to/day capacity
Dear Sir, We kindly refer
to the recent discussions. We thank you very much for your interest of the second hand
cement production line.
As we have pointed out we are currently in
a position to offer such a
cement production line in a very short time. Our offer comprises of
following main groups:
Group A Quarry
equipment For this group
we have chosen a double shaft
hammer crusher
MIAG Titan 80 D 75 with feed and discharge
conveyors. This unit is able to
crush about 650 t/h. This will
enables you to crush the
necessary raw mill feed in at least one shift. In case that you prefer smaller
crushers – let us know. We can offer such units
as well. Group B Raw
material grinding
For the raw material
grinding we offer a so called “KHD Tandem Mill”. This unit is a combined
system for drying and
grinding of the kiln feed. It consists of a
heated hammer mill and a tube mill 5,0 x 9,5 m. For more details please
see the process description in our respective offer section
Group C Preheater tower
section – delivery of drawings
As per our experience a
dismantling and re-erection of
an existing preheater tower is usually due to economic reasons not
reasonable. We have therefore
offered our engineering
services for the supply of
drawings for local
manufacturing. Moreover this
solution has the advantage that the preheater section can be tailor made for the particular application
(raw materials, fuels). Existing
fans of the preheater tower will be used as far as possible. The preheater tower section will include a pre-calciner system for
approx. 25 % of the necessary fuel input for the burning
process.
Group D Kiln and cooler
section The offered kiln was originally manufactured
by KHD Humboldt
Wedag AG, Cologne. With it’s dimension
4,8 m x 76 m and 3 roller
stations the kiln tube is able to handle 2750 t of clinker per
day. The cooler is made in 1969 by CPAG in Hamburg /
Germany. The cooler was
modernised in the year 1989.
On this occasion a
clinker roller crusher of latest technology was installed. As the
cooler grate plates were
used as spare parts for an
identical unit still in use the cooler will be supplied with
new grate plates.
Group E Cement grinding
The basis of our offer is an tube mill of 4,4 m x
13,11 m effective
grinding length and a main
motor capacity of 3800 KW..
Our offer comprises of all main equipment for this grinding plant including circuit bucket elevator and a
cyclone air
separator which is based on the
well proven ZUB separator
technology from Humboldt Wedag. Please
see our offer for details.
Please note that all current
existing AC drive motors for the groups B to E are based on a frequency of
60 Hz. Our offer includes therefore the exchange and
adaptation of all AC drives to
the 50 Hz power system.
As far as possible we will
incorporate used but
refurbished drive systems. We hope that
our offer meets your
requirements. In case of any
other open question please don’t hesitate to
contact us. Best regards

B DESCRIPTION
Plant type Dry process
clinker production line with pre-heater
tower technology. The
plant will be equipped with a
4 - stage preheater tower and pre-calciner section for 25 % fuel input.
Process description and
performance expectations:
Group A Quarry
equipment The crusher
was originally designed for a production of
400 t/h limestone with a product size of 0 – 30 mm. The average production at
site with a medium
crushable limestone was
700 – 750 t/h at a product size of 0 – 70 mm. Group B Raw
material grinding The raw material
grinding plant consists mainly
of a KHD Humboldt
Wedag Tandem mill grinding system. This
system consists of a
combination of a hammer mill
and a short tube mill. The system in general is described hereafter:
The impact hammer mill of
the Tandem drying-grinding plant works in conjunction
with a short air-swept tube mill.
Instead of a grate, the
impact hammer mill is
furnished with a solid bottom. The materials
leaving the
compartment tube mill which is equipped with classifying lining. A partial gas stream passes the tube mill for additional drying of the mill feed. After passing a
discharge diaphragm, the ground material is carried by means of the mill blower\\\\\\\\\\\\\\\'s return air through the ascending duct to the air flow classifier.
A cyclone system to separate the raw mix and a mill blower complete the plant\\\\\\\\\\\\\\\'s equipment.

Group C Preheater tower section – delivery of drawings Our offer includes the engineering services for a new preheater tower section. The design of the preheater tower is based on the characteristics of the raw materials to be processed on the fact that natural gas will be used as fuel for the kiln. In order make full use of the cooler capacity the preheater tower will be equipped with 4
cyclone stages and will be designed for pre-calcining. About 25 % of the necessary fuel will be introduced into the preheater tower calcining section. The combustion
air will be drawn trough the kiln tube – no tertiary air duct will be necessary. Group D Kiln and cooler section
The offered kiln was originally manufactured by KHD Humboldt Wedag AG, Cologne. With it’s dimension 4,8 m x 76 m and 3 roller stations the kiln tube is
able to produce 2750 t of clinker per day. The cooler was made in 1969 by CPAG in Hamburg / Germany and modernised in
the year 1989. On this occasion a clinker roller crusher of latest technology was installed. As the cooler grate plates were used as spare parts for an identical unit
still in use the cooler will be supplied with new grate plates. The cooler has a grate area of 73 m². With a clinker production of 2750 t per day
the specific cooler load is 37,6 t/m² * day. Group E Cement grinding
The Cement grinding plant is equipped with a tube mill made by TCEC. The dimension of the tube mill is designed for an effective grinding path of 13,11 m. The chamber division is 4,305 for chamber 1 and 8,805 for chamber 2. The mill
has installed 3800 kW via central drive system.
impact hammer mill and the tube mill are
pneumatically conveyed to
one common air flow classifier. Before entering
the impact hammer mill,
the raw material with particle sizes of about 70 - 100 mm, passes first a pre-drying
track, equipped with a double flap valve and with deflector
plates. The drying gases are
introduced through the upper of this pre-drying
track, which is adjusted to the moisture of the raw material. The pre-dried raw material, together with
the drying gases enters the
impact hammer mill.
The discharge of the hammer mill in the size of 0 –10 mm,
containing according to its
grindability about 15 - 35%
of finished product, is
carried by the gas stream through an
ascending duct
As separator the grinding plant makes use of a cyclone separator of the 2nd generation. The separator is build by TCEC and based on the KHD Humboldt
Wedag design of the so called “ZUB” separators. The separator operates as closed circuit separator with 6 cyclones.
At its coupling the mill can transfer 3800 x 095 = 3610 kW effectively. A usual grindability for OPC cement with 2800 – 3000 cm²/g acc. Blaine varies between 27
and 30 kWh/t finish cement. By this a final capacity of 120 – 130 t/h can be expected.
Currently the mill is equipped with a Polysius Polycom high pressure grinding mill as pre-grinder. This unit is available as option.

Total weight: approx.204 t Crusher history
The crushing plant was originally installed in 1964. The crushing plant was used to feed ball mills for raw material grinding in a cement plant. The current grit aperture is set to a final product size of 70 mm maximum. By changing this
into an air flow classifier.
During this procedure, additional drying is
performed. After separation of the fines, the rejects are fed into the short,
one-
aperture the final product size can be influenced with respective changes in the capacity.
