Cooling a pourable material, eg cement clinker, on an advancing grid, comprises passing a gas stream through the grid and the material

摘要

A process for treating, esp cooling a pourable material layer (20) on an advancing grid, comprises passing a gas stream through the grid and the material. The grid (10) is moved to and fro, while the material is held fixed, and the movement frequency is low, so no vertical mixing of the material takes place.
