Conclusions
Using traditional methods and radioactive isotopes we studied the decarbonization, sintering, change in properties and velocity of magnesite in a rotary kiln 170 m in length.
We established boundaries in the production zones (preheat, decarbonization, sintering, and cooling) of the kiln and the dwell time for the material in those zones.
In order to stabilize the regime and improve the cost-benefit factors of a rotary kiln, especially with a length of 170 m, it is necessary to submit for burning magnesite of a comparatively narrow grain-size composition with the maximum grain size of not more than 20 mm and of stable chemical composition.
We obtained equations enabling us to determine the velocity and dwell time of the material in the kiln zones, the initial average velocity of the charge, and calculated the productivity of the kiln.
