Increasing the thermal efficiency of a rotary kiln for

More uniform firing of dolomite of various fractions can be achieved by reducing the upper limits of the dolomite particle size to 10–12 mm and excluding fractions < 5mm. Considering the low resistance of chrome-magnesite brick in the firing zone it is necessary to use periclase-spinel brick. The use of GVM burners for burning natural gas in rotary kilns increases the output of the kiln and

Continuous thermal monitoring of rotary kiln They talk

Rotary kiln thermal monitoring Early warning of refractory damage. At the core of the sintering process, the kiln shell is a long cylinder made of steel, with a typical length ranging between 60-100m and weighing around 1000t. Despite this impressive mass, the kiln shell is a giant with feet of clay, exposed to harsh environmental conditions.
