Lime Shaft KilnLime Shaft Kiln

Brief Introduction:
Lime shaft kiln is generally refers to the lime kiln, solid fuel burning lime includes: coke, coal, such as fuel for calcining kiln, calcium carbonate, calcium hydrogen phosphate, metallurgical and other industries. The so-called modern environmental protection energy-saving mixed burning lime shaft kiln, refers to the reasonable ratio of height to diameter, can realize the kiln three thermal process is a tropical, pre calcining zone, cooling zone. The fuel energy can be fully utilized, and the top of the kiln feeding, kiln dust is closed in the whole operation process, flue gas by pipeline through the dust to discharge and no pollution emission. It from the material, cloth, level, temperature detection, unloading is mechanization or automation and control, which can save energy and to protect the environment.
 
Components:
The furnace consists of upper cloth, the middle part, lower part combustion rotary discharging part, discharging air locking part, transmission part and automatic control of PLC+ frequency composition, unloading the vortex cone towers, ventilation using high-pressure centrifugal fan at the bottom of the forced ventilation, drive shaft support structure, gear transmission, the transmission is stable and efficient, shell structure for the whole steel.
 
Performance characteristics:
1. The materials from the car via lifting derrick into the kiln top distributor, PLC automatic control and IPC + master controller monitors the speed accuracy and stability, improve vehicle (car running position can be visually displayed).
2. The top distributor timing automatic distribution technology, can realize the 120 cloth not to repeat, to ensure that the raw materials into the kiln distribution.
3. In order to facilitate the operation and control of the kiln body preheating zone, calcining zone, cooling zone, air outlet, site discharge hole total of 21 temperature sensors and 2 pressure sensors, the upper two fire inspection hole, the kiln to fence ladder.
4. The kiln bottom using vortex cone disc tower unloading to ensure product reached 95% for the massive.
5. The whole line from raw materials to finished products using 8 cameras will reflect the real-time live to the control room to operate.
6. A locking ash machine through the feeding tube to calcium oxide out of kiln firing outside the discharge mechanism.
