Brief introduction to lime rotary kiln. lime kiln, also known as lime rotary kiln or lime pit, belongs to rotary kiln; it is main equipment to calcine active lime, composed of cylinder body, support device, bearing device with hydraulic gear wheel, transmission device, lubrication device and sealing device, with simple structure, reliable operation and convenient automatic.
Lime is a multipurpose mineral that is a fundamental part of everyday life in human society which has numerous applications in different forms and content.. lime sizing. limestone is crushed into parts through primary crushers at the initial stage of 100 – 250 mm. based on initial sizes of extracted feed limestone, it may go through different other secondary or tertiary crushers for size.
For the limestone in the rotary lime kiln moves in counter current with the air flow in the kiln. and the preheated limestone will go into the rotary lime kiln for calcination. the rotary lime kiln will rotate constantly for a period of time to burn through the limestone. at the end, the burnt lime will be discharged into the cooler to cool.
Working principle of lime rotary kiln: limestone and fuel are loaded into the lime kiln (if the fuel is the gas, it should be sent through pipes and burner), preheating to 850 degrees, they are began to break down, and to 1200 degrees, calcinations is.
The rotary lime kiln is slightly inclined to horizontal and rotates on a set of riding rings. traditionally, in order to burn down the limestone thoroughly, rotary lime kiln is often very long. however, modern rotary lime kiln tends to be shorter and is equipped with pre-heater and cooler to save energy as well enhance quicklime plant.
Lime rotary kiln is also called roller rotary kiln. to make sure it’s air leakage coefficient is less than 10 percent, lime rotary kiln adopts advanced structure and reliable combined scale-like seal in both ends. it also uses composite refractory to reduce the loss of heat radiation. lime rotary kiln operating.
