Abstract
The invention relates to a method for the expansion of sand grain-shaped raw material () in which the raw material drops downwards through a substantially vertical heated shaft () provided with means () for heating, in which a shaft flow () prevails and to a dosing element () which can be connected to a substantially vertical shaft () and a conveying line (). In order to prevent the pressure fluctuations coming from the conveying line () in the area of the shaft (), a dosing element () is attached between the shaft and the conveying () line, in which the quantity of granulate which goes over from the shaft () into the conveying line () is regulated via means for regulating so that a defined material collection of the granulate is formed as a buffer in the dosing element (), which decouples the shaft flow () from the conveying flow.
