Abstract
The grate cooler at Eiberg Zement in Austria provides an example of how older grate coolers can be modernized and upgraded to meet the requirements of todays modern clinker cooling systems. The progressive modifications of the cooler system are described. The installation of the Muldengrate system, a hydraulic drive for the cooler grate and the riddlings drag chain, and the installation of a roller crusher have led to a considerable increase in the system operating reliability. The essential improvements, especially reduction of kiln heat consumption, are shown by the operating results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
