Know-how and innovation around cement plants
From old to new | No long way with Intercem. After a detailed check-up of the plant to be optimized and a planning phase aimed at cost-effectiveness, the necessary components for the plant are individually composed.
If for example up to that time only classic fuels could be used, such as oil, gas and coal, the upgrading of the preheater-technology makes the application of alternative fuels possible, as for example processed animal meal, domestic or industrial waste.
The Intercem preheater-technology comprises a 5-step-preheater with pre-calcination and integrated ter-tiary air duct connection to the clinker cooler. Upgrading the clinker cooler reduces the needed electrical energy to the minimum. The upgrade also includes the optimization of the burner technology and the filter technology, such as the kiln exhaust filter, the air cooler with exhaust filter and the gen-eral process filter. The exchange and the refurbishment of the roller station as well as an exact measurement and adjustment of existing rotary kilns perfectly complete the InterUp scope of supply.
Intercem’s refurbished spare parts increase performance capacities and minimize the energy input and consumption considerably. Moreover old technologies are replaced by efficient new components in a very economical way.
An example before-after shows how an outdated plant can be converted into a highly efficiently working cement plant, without discarding and renewing plant components which are still productive and powerful.
Act internationally | Intercem is acting internationally and always offers to each customer the most economical solution, which can be planned and manufactured – as per the customer’s requirement – nationally, in Europe or globally. Specific manufacturing processes, different performance classes as well as raw materials to be used and transport facilities are included in the planning.
Thus, clients do not need to adapt to the plant, the plant is adapted to the client’s requirements. The capacity areas of the offered products and services vary from the minimum capacity up to the maximum possible. Existing cement plants are optimized, modernized and made more efficient by InterGrind. In case of completely new grinding plants customers have the choice between Intercem-owned products or alternative products. In every case, a high grinding quality, an over-average input and low wear rates are achieved.
Already existing ball mills can be equipped with completely new interior fittings leading to high performance again. For plants in operation, Intercem has spare parts on stock which can be tailor-made and adapted to the existing plant. Furthermore Intercem offers a comprehensive consulting, which can reach from material handling to the development of new cement varieties and their implementation into the regional markets.
With all InterGrind solutions Intercem achieves an individual, needs-oriented and product-specific result, which could not be realized with standard solutions.
Flexible and compact | Consequent further development of the separator technology results in a high efficiencyseparator of the latest generation, corre-sponding to the highest demands. Optimization of the separation chamber geometry and optimized streaming processes have been proven in different reference plants. Areas exposed to a high wear potential are equipped with highly wear-resistant materials in order to achieve a maintenance friendly product.
In direct connection with the ball mill de-dusting the separator-circulating-air-fan is omitted. This leads to a reduction of the specific labor need in the complete grinding plant.
Both separator types separate the material with the lowest bypass rate and highly efficiently. Moreover the compact construction of the high efficiency separator allows – in con-nection with further plant components – the exchange of old separator types at the same places of installation. Complicated and cost-intensive interventions into existing buildings are omitted.
The manufacturing of the high efficiency separators takes place in the manufacturing center in our site in Oelde. As an option, separator housing components can also be produced by local workshops in order to come up to high economical requirements.
Connect and cement | Connect and produce cement exactly where it is needed. In sufficient quantities, top quality and round the clock. InterMod, the modular system makes it possible.
The modules are pre-assembled, individually combinable, quickly removable, ultra-flexible and designed for rapid change of location. They are equipped with proven single products and electronically pre-installed.
Smaller plants are ready for operation in only a few weeks from the moment of delivery. In the same short period of time they can be disassembled and stored or rebuilt in another location. This enables the operator to react in a flexible way to economic, cultural, political or environmental modifications.
Additionally, customers who want to increase the added value of their plant find the ideal solution with InterMod. Traders can produce their own cement and react flexibly to customers’ requirements, they become independent from suppliers and can adapt to changing local circumstances. As InterMod does not need long planning- and construction times, assembly costs including accommodation are extremely reduced.
Disassembly is also quick and safe. The transport to the next operation site or to the interim storage is possible without high logistical effort. When re-assembled, the modules can be adapted to the new requirements.
Investment costs can be planned risk-free at an early stage, because for each modular system the needed capacity, the quality of results, the composition of components, the following usability, an eventual interim storage etc. can be stipulated in advance.
Own technologies | InterSeal has been especially developed by Intercem, topping by far standardized minimum requirements. It comes up to the real and daily high requirements of production flow in all areas. Thus, InterSeal cares for an increased operational safety and guarantees a long-term, trouble-free operation of the plant.
Adapted by Intercem engineers on site, existing plants are completely safe. The adaptation is executed digitally by a 3D-Scanner, which assures absolute precision work for the assembly.
As connecting element between rotary kiln and preheater, InterSeal avoids the inlet of ambient air and the escape of 800 °C hot raw meal. Furthermore, rotating as well as vertical and horizontal movements of the rotary kiln are absorbed and balanced. All this creates an enormous safety for robust production processes.
Effective and efficient | Cement plants optimized by Intercem work quicker, more effective and with more performance quality. Very often the existing loading- and packing systems have to be adapted to these new conditions. Intercem offers the ideal solution for this.
Intercem engineers analyze the new requirements with 3D-scanners and draw up a 3D-drawing of the complete plant according to the so-achieved measurements, volumes etc.
This can either mean a completely new construction or the integration into existing production areas of the build-ing. At the end of the analysis a real shot of the new packing plant visualizes the future situation.
Acting instead of reacting | Proximity to the customer, direct communication and a continuous flow of information are particularly important to us. A pre-condition for this is an internal and external cohesion, establishing long-standing employee loyalty as well as loyal connections to the customers. We recommend ourselves with our work and our service offers for follow-up orders. As a rule we have already managed two or more offers for individual customers.
Our service offers contribute significantly to this success. Whether before, during or upon handover of a project: our test engineering and the expert certification always assure constant, good quality. That is what Intercem is well known for. And after having finished a project, our maintenance service always ensures a quick, smooth and reliable operation of the plants we built, no matter where they are.
Our most important services at a glance:
- Mechanical engineering
- Process engineering
- Electrical engineering
- Civil engineering
- Service on site
- Project meetings
