Lime rotary kiln is the main equipment of lime production line. It is widely used for many industries like metallurgy, chemical industry, building refractory materials, environmental protection, etc.Great wall lime rotary kiln has many advatages: High Automation Level, Waste Heat be Reused Effectively, Low Energy Consumption and so on. 1.
Hydraulic lime has properties intermediate between ordinary lime and Portland cement but is produced in a similar way to ordinary lime. In addition to containing calcium hydroxide, the chemical which makes up ordinary lime, hydraulic lime also contains calcium silicates similar to the main cementitious components of Portland cement.

The high pH of lime acts as a fungicide preventing mold from growing in the lime plasters. Disadvantages of lime plaster: Hydraulic lime plaster is not as hard as cement plaster. When the plaster dries, the pH drops to about 8.6. Non-hydraulic lime plaster requires moisture to set and prevents it from drying for several days.
