Abstract
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.
Claims7
A method for heat treatment of a grain-shaped feed material wherein a first material flow containing the grain-shaped feed material is fed into one end of a calcination device;
- wherein the grain-shaped feed material undergoes a heat treatment within the calcination device in order to produce grain-shaped heat-treated material by removing water of crystallization and/or carbon dioxide from the grain-shaped feed material;
- wherein a second material flow containing the grain-shaped heat-treated material is released from a second end of the calcination device;
- wherein the second material flow is directed into a measuring container;
- wherein the measuring container comprises a base surface having openings through which openings at least one part of the second material flow being directed into the measuring container is draining continuously;
- wherein the measuring container is connected to a weighing device;
- wherein a weight of the grain-shaped heat-treated material flowing through the measuring container is continuously measured by the weighing device in order to determine the bulk density of the grain-shaped heat-treated material flowing through the measuring container and to detect deviations from at least one desired bulk density of the grain-shaped heat-treated material;
- and 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.
