70-800 Tpd Rotary Kiln Metallurgy Machine Activated Limestone Rotary Kiln
1. The technical characteristics of complete rotary kiln system for active lime production are as follows:
(1) The vertical preheater with advanced structure and low pressure loss can effectively improve the preheating effect. The decomposition rate of limestone entering the kiln after preheating can reach 20 ~ 25%, and fine limestone of 10 ~ 50mm can be used;
(2) reliable rotary kiln at both ends of the combined scale seal, so that the air leakage coefficient is less than 10%, the use of composite refractory lining, to reduce radiant heat loss;
(3) filling type, zoned ventilation circular or square vertical cooler, the limestone temperature of the cooler is: 80℃ ambient temperature, easy to transport, storage, and can preheat the secondary air into the kiln to more than 700℃, reducing the moving parts and special materials.
2. Case of lime rotary kiln K-K Type Lime Rotary Kiln Metallurgy Machine
Our country is a big iron and steel country but not a strong iron and steel country, an important reason is the poor purity of steel making, one of the key factors is the technical barrier of the active lime. Through continuous innovation, Luomine has developed large-scale activated lime production technology, process and equipment with a daily production capacity of 750 tons to 1200 tons. The overall technical level has reached the world advanced level, and the main performance indicators are in the international leading level.
The application of this technology not only improves the smelting quality, reduces the production cost, but also produces obvious benefits in the aspect of energy saving and emission reduction. According to the introduction, taking a 750T/D production line as an example, can save standard coal 5,198 tons/year, electricity 1.24 million KWH/year, waste 150,000 tons/year. At the same time, activated lime used in steelmaking can reduce a variety of consumption, shorten smelting time and so on. It is used in steelmaking to save 41 million kilowatt-hours of electricity every year and in alumina and other industries to save 25 million kilowatt-hours of electricity every year.
