Method for distributing material over the width of a conveying grate. In order to induce the material to flow off from a width section (6, 11) onto a second width section (7, 8), the first width section is operated at a lower speed of advance than the second (7, 8). In addition, braking or a smaller conveying length can be provided in the first width section (6, 11), as compared with the second (7, 8). The invention also relates to a push grate for carrying out the method.

A method of cooling white cement clinker sintered in a rotary kiln includes the following steps: introducing the white cement clinker from the rotary kiln into a first cooling stage; comminuting the white cement clinker in the first cooling stage; quenching the white cement clinker with a coolant in the first cooling stage in a short dwell period in an oxygen-poor environment to a mean temperature of approximately between 650.degree. C. and 750.degree. C.; introducing the white cement clinker from the first cooling stage into a second cooling stage; mixing and simultaneously conveying the white cement clinker in the second cooling stage in an oxygen-poor environment for a period of at least 15 seconds for obtaining a homogeneous mixture of particles of the white cement clinker and for further cooling the white cement clinker to a temperature of approximately between 550.degree. C. and 650.degree. C.; after the mixing and conveying step, introducing the white cement clinker into a third cooling stage; and cooling the white cement clinker in the third cooling stage by an air stream.
