Founded by Franz Plochberger in 1990, CEMTEC Cement and Mining Technology GmbH with its headquarters in Enns, Upper Austria, is today one of the leading global specialists in wet and dry grinding technologies for the most wide-ranging bulk materials, industrial minerals and ores.
In addition to systems for grinding processes, CEMTEC’s product range also includes solutions for thermal (for instance, drying and cooling) and mechanical (such as mixing, washing, conditioning and pelletizing) treatment of bulk materials, minerals and ore. CEMTEC offers complete turnkey projects, as well as single items of machinery, from planning through to commissioning.
The parameters for each individual application can be verified in CEMTEC’s pilot test plant and laboratory. With this kind of pilot test, CEMTEC can guarantee that the selected solution will perform according to customer requirements. CEMTEC is able to offer wet and dry grinding tests in open and closed circuits, along with grinding tests with vertical roller mills, batch tests and drying tests. Many other material testing methods complete CEMTEC’s testing portfolio.
Until now, CEMTEC has delivered more than 350 ball mills, rotary drums, dryers and pelletizing discs to locations as diverse as the Australian outback, Siberia and Panama. Of these machines, about one quarter was sold to the cement industry. Outside this sector, CEMTEC also supplies ball mills in all practicable power ranges and designs for virtually all conceivable applications. CEMTEC mills daily prove their capabilities in the comminution of all types of ore, up to and including the grinding and preparation of additives for the paints and coatings industry, and also fly ash, coal, rubble, waste and for flue-gas desulfurization (FGD) installations.
CEMTEC has not only manufactured Europe’s largest cement mill of Ø5.20 × 16.75 m with an installed main motor capacity of 2 × 4,200-kW and a capacity of 200 tph, but it has also manufactured one of the world’s largest ball mills. This 18-MW wet-grinding ball mill, which operates in overflow design and closed circuit (with hydro cyclones), has a dimension of 8.2 × 14.0 m and is designed for a fresh-feed quantity of 1,230 tph of gold ore.
Whether it is required to grind raw meal, solid fuels or if potential clients are looking for finish grinding of clinker and gypsum or limestone, pozzolans, granulated blastfurnace slag or fly ash, CEMTEC strives to offer the most effective and efficient solution.
Based on the in-house grinding technology featuring high pressure grinding rolls in combination with ball mills and dynamic separators of the latest development CEMTEC is capable to adapt the project to individual needs.
Only recently CEMTEC has been awarded as EPC contractor for several cement grinding terminals in Western and Sub-Saharan Africa. One of these new grinding facilities for Ciments de l’Afrique, which is to be installed 15 km outside Abidjan, Ivory Coast, will have a capacity of 500,000 tons per annum which doubles the existing production capacity.
The key components of the plant are a 3.8 x 11.0-m shell-supported ball mill with installed motor power of 2,250 kW and a separator CTC-110 with improved rotor design to reduce power consumption and increase separation efficiency.
The scope of supply includes the raw material handling, including intermediate silos, grinding section, cement silos with bulk loading, transport to existing packaging plant, the electrical and control system, the structural steel building, civil works and complete erection.
The main challenge is the integration of the new grinding facility into the existing plant structure with minimal interference and in the shortest possible time. This is ensured by the clear vision and technical specification of Ciments de l’Afrique and the professional flexibility CEMTEC towards the fulfillment of the specification even before contract signing. The plant will be fully operational towards the end of 2015.
