Revolving disc clinker cooler

A clinker cooler that operates according to the "revolving disc" principle, which has been used for many years in the steel industry was recently introduced by CemProTec – and is regarded as the 5th generation of coolers . The cooler replaces the travelling grate is by a revolving disc which takes about 30 minutes for one complete rotation. The cooler improves the conveyance efficiency of a clinker cooler. A static grate is installed at the cooler inlet, which is positioned at a 90° angle to the kiln outlet. This eliminates problems caused by different centre lines of kiln and clinker cooler and by segregation of the clinker particle sizes over the width of the cooler. However, this new type of cooler has not yet been proven in full-scale operation
