Abstract
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.
Claims10
A system for heat treatment of a grain-shaped feed material comprising:
- a calcination device that is designed to perform a heat treatment on the grain-shaped feed material being fed into a first end of 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 the calcination device has a feeding opening for receiving a first material flow containing the grain-shaped feed material and a release opening for releasing a second material flow containing the grain-shaped heat-treated material;
- and a device for measuring the bulk density of the grain-shaped heat-treated material comprising,
- at least one measuring container for receiving at least a part of the second material flow, wherein the at least one measuring container has a base surface having openings in order to allow at least a part of the received second material flow to drain continuously from the at least one measuring container,
- a weighing device being connected to the at least one measuring container for continuously measuring the weight of the grain-shaped heat-treated material flowing through the at least one measuring container in order to determine the bulk density of the grain-shaped heat-treated material flowing through the at least one measuring container and to detect deviations from a desired bulk density of the grain-shaped heat-treated material.
