Zusammenfassung:	A method for calcining and cooling material such as carbonate rocks may be employed in a parallel-flow regenerative shaft kiln that has two shafts, which are operated alternately as a calcining shaft and as a regenerative shaft. Material flows through a preheating zone, a calcining zone, and a cooling zone to a product outlet. At least one gas flow is compressed by a high-pressure fan and introduced into the parallel-flow regenerative shaft kiln. The high-pressure fan is configured as an axial fan or as a radial fan, having an impeller through which flow takes place axially or radially. A parallel-flow regenerative shaft kiln may also be utilized to perform such methods.
