1 From second-hand machines to turnkey projects
Intercem has been in the cement industry since the 1970s. It all started with the sale of second-hand machines for the cement industry. These were professionally overhauled and then sold worldwide, in almost good as new condition. In 2003, Intercem Engineering GmbH was founded and in 2007, Intercem Installation GmbH followed.

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.

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.

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

 

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.

 

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.

 

 

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.
