how about the activity of lime after lime kiln calcination?
It is suitable for calcining high-activity lime. Under the same conditions, the lime activity produced by the lime rotary kiln is higher than that of the shaft kiln, and the activity can reach 400ml or even higher. In recent years, environmental protection policies have become more and more strict.

Calcination of Lime - J-STAGE
Using the illustrated figures, height in calcining zone 5.1 m (Fig 3), height in preheating zone 0.9 m, hieght in cooling zone 2.5 m, 8.5 m corresponds to the total height of kiln. It may be concluded that the raising the calcining temperature, reducing the stone size and growing the kiln height are essential for increasing the lime production.

How Lime is Produced - Arij Trading
· Calcining - The fuel is burned in the preheated area from the cooler zones and as the limestone moves down the kiln, the emit heat from fuel turns the limestone into quicklime and carbon dioxide (CO2). Maintaining a sufficiently high temperature in the range of 1200 -1 300 C to adjust the reactivity is crucial.
