Abstract: A method or an arrangement for making the fired-material discharge stream from a rotary kiln more uniform upstream of a cooler is distinguished by the fact that at least some of the fired material is conveyed out of the coarse-material discharge region (5) toward the fine-material discharge region (4) and/or at least some of the fired material is conveyed out of the fine-material discharge region (5) toward the coarse-material discharge region (5) before it reaches the cooler.

Abstract: A jaw crusher is positioned within a duct connecting a high temperature furnace outlet and a cooler for crushing high temperature cement clinker material discharged by the furnace. The jaws are provided with cooling air-swept ducts that extend through the jaws and into the crushing chamber. The working surfaces of the jaws are provided with imbricated protective elements. A stationary jaw member within the duct provides a partition forming an air flow duct portion and a movable jaw member cooperates with the stationary jaw member to delineate a discharge crushing chamber separated from the air flow duct portion. The movable jaw is positioned at the wall of the duct for easy access while the drive mechanism for the movable jaw is located outside the duct.
