Magnezit Group commissions the most powerful in the world high-temperature shaft kiln for firing of refractory raw materials

Magnezit Group commissioned for industrial operation a unique thermal unit — high-temperature shaft kiln Polysius AG (Germany) with annual production capacity of 80 thousand tons at Satka production site (town Satka, Chelyabinsk region).

The new kiln has analogues neither on the territory of CIS, nor in the world. Before launching the kiln in Satka annual production capacity of similar kilns of the company Polysius AG, operating in various countries of the world, did not surpass 50 thousand tons.

The high—temperature kiln was built within the framework of the biggest investment project of Magnezit Group for increase of magnesia clinker annual production volumes up to 130 thousand tons. Novel technological solutions, employed within the framework of the project, correspond to the highest world standards including energy efficiency and environmental safety.

The kiln was built during record time-frame: the foundation pit was delineated by the close of the year 2011 and first metal poles were installed in early 2012. Ignition of the kiln took place on July 4 of the current year. During several days the kiln has been operating in heating mode, temperature and charging volumes increased gradually. At present the kiln reached the targeted technical parameters and switched over into the mode of industrial operation. Representatives of the concern Polysius AG, under whose control the kiln was started, point out high level of competence of «Magnezit» specialists, who carried out ignition of the kiln and its bringing to the targeted productivity parameters.

Magnezit Group is the only producer of dead burnt magnesia clinker on the territory of Russia and CIS countries. Dead burnt magnesia clinker is a high quality material for production of modern refractories, required by enterprises of ferrous and non-ferrous metallurgy, cement industry. Competitive advantage reached after implementation of this project remains for the moment unattainable for other refractory enterprises on the post-soviet territory. After commissioning of the second unique unit — multi-hearth furnace Polysius, construction of which will be finished in autumn of current year, Magnezit Group will implement complete cycle of magnesia clinker production. Total volume of investments into construction of the shaft kiln and multi-hearth furnace surpassed 2,3 billion rubles.

The unique production facility was initiated in 2008 after commissioning of Maerz high-temperature shaft kiln with annual productivity of 50 thousand tons. Technologies of fine grinding and briquetting of magnesia powders were united in single technological cycle, as well as firing and all this finally allowed to produce material with excellent targeted characteristics.

Implementation of the project for increase of magnesia clinker production volumes will permit Magnezit Group to transfer to the clinker technology up to 70 % of treated raw materials, to expand considerably range of manufactured novel products, to improve cost-effectiveness of production and productivity of labour. Resources conservation and introduction of advanced technological solutions will permit to preserve mineral wealth for future generations and to reach the highest level of environmental safety of production.

Magnezit Group (headquarters in town Satka, Russia) is a recognized world leader in the field of production of magnesia products. It is an integrated company, which ensures complete cycle of refractories production beginning with mining of raw materials and up to engineering and operation service. The structure of the Group is composed of production and servicing enterprises on the territory of Russia, China, Slovakia and Ukraine as well as a wide network of servicing and trading representative offices. Employing possibilities of our production sites we create novel technological cycles for production of high-quality products, corresponding to the highest world standards.

The company Polysius AG (headquarters in town Beckum, Germany) was founded in 1859 and specializes in the field of development and production of equipment for mining, metallurgical, chemical, energy and cement branches of industry. In 1971 the company was purchased by the concern Krupp and then became part of the unified concern ThyssenKrupp. After takeover of Maerz Ofenbau AG (Zurich, Switzerland) and RCE Industrieofenbau Engineering GmbH (Radenthein, Аustria) the company Polysius AG is presented on the market of high-temperature furnaces for production of sintered magnesium oxide, dolomite and aluminium oxide as well as of multi-hearth furnaces for calcinations of fine materials and slurries. The first shaft kiln Polysius operates in town Radenthein, Austria). Its annual production capacity is 25 thousand tons. It was commissioned in 70-s of the last century and successfully operates up till now.
