Active lime rotary kiln

Fuel economy, environmental protection and energy conservation are the main combustion principles of the new technology active lime kiln. The soil kiln has serious environmental pollution, the working environment is extremely harsh, and the work intensity is large. The new technology active lime rotary kiln solves this problem. The amount of fuel used is related to the calorific value of its furnace type and fuel. The heat required for calcining lime is derived from the combustion of fuel. The fuel and limestone are simultaneously distributed into the kiln, and different furnace types and different heating methods are used. , determines the calcination effect of the lime kiln.

product description

Technical performance and characteristics

Smooth operation, reasonable structure
The single machine runs stably, the maintenance amount is small, the operation rate is high, the output is large, and the performance is excellent. The kiln head cover can be integrated with the cooler, with a small footprint and good sealing. The vertical preheater is installed at the kiln tail, which effectively recovers the heat taken away by the exhaust gas, and also reduces the load for subsequent dust removal.

working principle

The main component of limestone is calcium carbonate, and the lime component is mainly calcium oxide. After the preheater is preheated, the limestone begins to decompose at 850 ℃. From the kiln tail (the high end of the cylinder) into the kiln to 1200 ℃ to complete the calcination, due to the tilting and slow rotation of the cylinder, it is tumbling in the circumferential direction. The axial direction (from the high end to the low end) is broken down into CaO and CO2 by sintering in the rotary kiln. Different kiln shapes have different preheating, calcination, cooling and unloading methods.
