Active lime has the characteristics of low volume density, large porosity, large specific surface area, and high chemical purity, so it has high activity. It is mainly used in building materials, steel, ferroalloy plants, power plants, calcium carbide plants, paper mills and other industries.

 

Rotary kiln active lime calcination system is the main production process for the production of active lime. It has the advantages of high output, low burn rate, stable product quality, high activity, convenient operation, and can use small particles of limestone to produce lime. The production scale ranges from 100t/d to 1200t/d, which can meet the needs of various industries. At the same time, the active lime calcination system of the rotary kiln can use various fuels, such as pulverized coal, coke oven gas, converter gas, blue coal tail gas, diesel, heavy oil, petroleum coke, etc.

 

Vertical preheater, rotary kiln and vertical cooler are the three main equipment of the active lime calcination system of rotary kiln. The vertical preheater uses high-temperature flue gas from the kiln tail to preheat the limestone raw materials so that the limestone is in the preheater. Reach 25~30% decomposition, which has obvious effects of energy saving and increasing system output. Rotary kiln is the key equipment for calcining active lime. Limestone is fully decomposed in the rotary kiln to produce lime, while the vertical cooler can be shorter The high-temperature lime is cooled to below 100°C within a period of time, while the cooling air is heated to above 600°C, which is used as combustion air for the rotary kiln to save energy.

 

Henan Zhengzhou Mining Machinery Co., Ltd. has been engaged in the research, development, manufacturing and engineering contracting business of the rotary kiln active lime calcination system, and has accumulated a lot of production experience. The rotary kiln active lime calcination system produced by it has been well received by users at home and abroad. Good social benefits have been achieved.
