Causes and composition of excessive lime?
In order to speed up decomposition, the calcination temperature is usually increased to 1000~1100 degrees Celsius. Because of the large size of limestone raw material or uneven temperature distribution in the kiln, lime and burnt lime are often included in lime
Calcium carbonate in poor lime is not completely decomposed and lacks cohesive force when usedExcessive lime structure is dense, and the surface is often coated with a layer of molten material, which is slow to mature
The rock, which is mainly composed of calcium carbonate, is calcined at an appropriate temperature. The product is lime, also known as lime
