A method for heat treatment of a grain-shaped feed material uses a calcination device in order to remove carbonate or water of crystallization from the feed material. In order to continuously check the quality of the heat treatment process, the bulk density of the heat-treated material is measured continuously, wherein upon detection of a deviation of the determined bulk density from the at least one desired bulk density at least one heat treatment parameter of the heat treatment is adapted automatically or manually.

Method for heat treatment of a feed material

A method for heat treatment of a grain-shaped feed material using a calcination device to remove carbonate or water of crystallization from the feed material are provided. To continuously check the quality of the heat treatment process, the bulk density of the heat-treated material is measured continuously, wherein upon detection of a deviation of the determined bulk density from the at least one desired bulk density at least one heat treatment parameter of the heat treatment is adapted automatically or manually.

System for heat treatment of a feed material

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 forming a temperature profile (), in which a shaft flow () prevails wherein the raw material () expands as a result of heat transfer in the shaft () to form expanded granulate () and the granulate formed () is passed into a pneumatic conveying line () with a conveying flow () for further transport. In order to continuously check the quality of the expansion process, the bulk density of the expanded granulate () is measured continuously, wherein upon detecting a deviation from at least one defined bulk density, the temperature profile () in the shaft () is adapted automatically or manually and/or the feeding of raw material () into the shaft () is reduced automatically or manually.
