Production of Cement and Glass

Fans are required during the production of fireproof stones and their use in the glass and cement industry (brickwork for glass tank furnaces and rotary furnaces) for air circulation for drying, baking and cooling.

In the refractory industry, similar drying and baking processes take place, as well as for the production of roof tiles and building bricks.

High energy efficiency and a long service life for the conveyance of cold and moist air as well as hot exhaust gases in the dryer and tunnel furnaces are necessary for the production of dense refractory bricks.


During the production of float glass, the hot molten glass is cooled stress-free in the lehr by centrifugal fans. It is necessary to convey the air volumes without pressure fluctuations and with a high degree of availability for the individual temperature levels during the cooling phase. This takes place with special impeller geometries and the use of impeller materials that have a long service life.


When manufacturing cement clinkers in rotary furnaces, the brickwork of the fireproof stones heats up as a result of the process, which has an impact on the service life of the furnace shell. High-efficiency axial cooling fans cool the critical areas of the furnace shell. They convey cooling air in a targeted manner with a high air speed to the areas of the furnace shell prone to wear in order to increase its service life. Furthermore, special impeller geometries are used with coatings that prevent the caking of raw meal and to guarantee the high availability and service life of the fans.

Refractory bricks for lining in rotary kilns for the cement industry are produced with comparatively similar process technology as in the heavy clay production of bricks or roof tiles. For the flue gas afterburning, proven high-pressure fans from EVG are used, which specifically reduce the harmful components and flue gases with efficient air routing and gas tightness as well as long service lives in 24/7 operation.

Precision in air flow is as important as compliance with the customer-specific process parameters. To ensure that this is achieved reliably, EVG supplies 16 cooling and exhaust fans for float glass production. Long operating times with low maintenance are required to maintain the cooling time and to avoid mechanical stresses.
