New coal dust dosing systems

In November 2019, Solnhofer Portland Cement awarded Intercem the contract for the engineering, planning and installation of 2 coal dust dosing systems. The existing plant was recorded by laser scan and, based on this, the dosing units, the steel structure, the platforms and the conveyor piping were planned. As in a similar preliminary order, the special requirements of the pulverized coal dosing systems regarding silo lining with stainless steel, the steel construction and the design of the pneumatic conveying piping were taken into account. The installation is coordinated in such a way that the various installation sections ensure continuous kiln operation. The project is scheduled for completion in August 2020.

New Project: Les Cimenteries de la Basse Guinée – Groundbreaking

On 8 April 2019, the foundation stone was laid for the new cement grinding plant “Les Cimenteries de la Basse Guinée” in Kamsar, Guinea. The ceremony was celebrated in the presence of high-ranking members of the government, leading personalities of the client and the managing director of Intercem, Olaf Michelswirth, with two of his employees and the active participation of the population. With the help of large-format layouts, Intercem was able to demonstrate to the visitors what the grinding plant will look like. The speakers emphasized the importance of the project for the further economic development of the West African country. The aim is to supply the Boké region with sufficient cement at a favourable price. In addition, the plant will create 80 direct jobs and several hundred indirect jobs. Mansa Moussa Sidibé, Chairman of the Board of Directors of Les Cimenteries de la Basse Guinée, confirmed that this plant would make it possible to supply Guinea and neighbouring countries with high-quality cement. The start of construction is now eagerly awaited.

New cement grinding plant in Kamsar, Guinea

Following the successfully finished projects in Ivory Coast and Burkina Faso, Intercem has been granted a new order in West Africa from “Les Cimenteries de la Basse-Guinée” for a 500.000 tpa cement grinding plant including raw material shed, hopper station, packing plant and truck loading station in Kamsar, Guinea.

Project description:

The contract contains the raw material storage with a capacity of 12.000 t, a 70 tph cement grinding plant with VRM (vertical roller mill with 4 rollers and installed power of 1.250 kW) and high efficiency separator, the transport to 2 x 1000 t cement silos, 2 truck loading stations for bulk cement, the packing plant with 8-spout rotary packer and 2 loading stations for bagged cement, the sub-systems, the electrical equipment, the complete engineering, the supervision of the erection and the commissioning. The entire equipment will be delivered exclusively by renowned European manufacturers.
Groundbreaking is previewed for beginning of March 2019.
Schedule: Start of cement production is scheduled 14 months after coming into force of the contract

 

Winter revision

For many years Intercem has been commissioned with the maintenance work in the course of the winter revision in the cement works of a well-known German concern. This shows that Intercem has proven to be a reliable partner in the quality of its work.
The following works were carried out:
Refurbishment of the screw field of one dryer, lining of the second dryer with track plate, renewal of two honeycomb fields and an intermediate field as well as screw controls. The complete tooling required for this purpose, the blasting system, a compressor and a forklift were provided by Intercem.

Optimisation of the secondary fuel dosing system

 

In a German cement plant the secondary fuel dosing system had to be optimized and Intercem was commissioned to do so. The scope of delivery includes the following items:

Disassembly on site, refurbishment of the trough chain conveyors still to be used, construction of a new bunker and installation of the refurbished screws. This combination of new and refurbished parts ensures that the costs for the customer can be kept as low as possible. The engineering as well as the assembly of the new components and the provision of the necessary cranes, hoists and other equipment are also included.

New silos for Lübeck

 

 

The cement plant Lübeck has appointed Intercem to supply a silo unit consisting of 4 steel silos with a capacity of 1,200 m3 each. In addition, the bulk loading and the complex cement conveying via air slides and bucket elevators leading over the complete area of the plant are part of the scope of supply. Further services:

Engineering and associated plant components, such as

support structure
catwalks
filters
bucket elevators
return lines
electrical equipment

as well as building application and dispatch automation.

Intercem was able to convince the German cement manufacturer of its efficiency and flexibility with this turn-key solution. Completion is scheduled for the third quarter of 2019.

 

New activities in Russia

Intercem has been awarded the contract to supply a high-efficiency separator ICS 143, as well as the associated plant aggregates for a new cement plant in Russia. The high-efficiency separator, an in-house development manufactured in the company workshop, has a capacity of 115 t / h at 3,000 cm2/g acc. to Blaine and a total output of 258 t/h. The volume flow classifying air is 143.000 m3/h. The scope of supply also includes the engineering for the complete grinding plant as well as the supervision of the assembly and the commissioning of the components included in the delivery.

New order for Intercem of renowned German cement producer

 

 

Intercem has received an order for the optimization of the raw meal dosing from a renowned German cement plant.

Currently the raw meal dosing of a kiln is situated in front of the bucket elevator of the heat exchanger building. After the bucket elevator, the material flow is divided volumetrically by an air chute system to both of the heat exchanger pipes. The sealing to the exchanger is realized by two rotary valves.

The existing dosing will also be used further on for the realization of the feed rate. After the bucket elevator, the flow rate is divided by an adjustable splitter. The material is guided to the two dosing bunkers by means of air chutes. Each single pipe of the heat exchanger is separately supplied with raw meal gravimetrically from the dosing bunkers by mass flow dosing devices. Subsequently the raw meal is led to the feeding point over a short pneumatic conveyor.

Intercem’s scope of supply and services comprises the measurement by 3D scan of the respective area in the heat exchanger building as well as the delivery, assembly and commissioning of the process plant. The special challenge is the planning into the existing site and – due to the height of the building – the assembly of the plant without crane support.
