sintering magnesite in a shaft kiln

Calcination/sintering grecianmagnesite

Calcination/sintering. There are three rotary kilns as well as two shaft kilns with a combined calcination capacity of 550 tpd. Kiln feed magnesite is fired in the kilns to produce either caustic calcined magnesia (at about 900°C) or deadburned magnesia (at about 1.800°C).

The natural magnesite or light-burned magnesia is calcined in a rotary kiln or shaft kiln at a temperature of 1500~2300℃ to grow and densify the magnesia crystals and transform them into almost inert sintered magnesia, also known as heavy Burnt magnesia. To achieve sintering of pure magnesite, the calcination temperature should be above 2000°C.

Refractory Material For Cement Rotary Kiln AGICO

Although the use of magnesite-spinel brick solves the chromium-free problem of cement rotary kiln to some extent, there are still many problems. For example, it is difficult to form a stable kiln skin by using magnesite-spinel brick in the rotary kiln sintering zone, which is easily affected by the atmosphere and heat load, so its service life has always been the bottleneck of the cement kiln.
