sintering magnesite in a shaft kiln

The sintering of magnesite over the length of rotary

1968-9-1  According to the physicochemical processes taking place in magnesite during calcination, the rotary kiln, starting from the loading head, can be tentatively divided into the following zones: preheat up to 15 m of the length, decarbonization 15–65 m, sintering 65–81 m, and cooling 81–90 m.

Sintering of caustic magnesite dust over the length of

The recrystallization of the periclase, sintering, and agglomeration of the powder occur mainly in the section 45–75 m of the furnace length in the presence of melt. During the burning in a 90-m rotary kiln of unground caustic magnesite dust, the apparent porosity of the powder resulting from its grains diminishes from 50–60 to 24%.
