Main factors affecting the capacity of lime rotary kiln

Lime, as a basic raw material, plays an extremely important role in building materials, metallurgy and other industries; The so-called lime is a product containing CaO as a main component obtained after the limestone emits CO2 gas at a high temperature. There are many kinds of modern lime furnaces, including traditional vertical shaft kiln, rotary kiln, and annular sleeve shaft kiln. In our country based on national conditions, this year the focus is on the development of rotary kiln with preheater and vertical cooler. Therefore, the capacity of the rotary kiln will directly affect the development of the entire industry, and the main factors affecting the rotary kiln products are: 1. Effects of Altitude on production capacity As altitude increases, the atmospheric pressure and air density will decrease. In this way, under the condition of ensuring the constant gas quality, the volume of gas required for the equipment will be increased, which will reduce the capacity of the rotary kiln, and at the same time it will lead to incomplete combustion of the fuel, and the actual capacity of the rotary kiln will be reduced. 2. Effect of Limestone Particle Size on Production Capacity If the particle size ratio is too large, in order to completely decompose the limestone with a large material content, the small particle size will lose its activity due to overheating. On the contrary, the large particle size limestone will produce yellow heartburn and affect the product quality. Therefore, the smaller the particle size ratio of limestone, the higher capacity and the higher quality. In general, the particle size of calcined limestone in the rotary kiln is selected from 10 to 50 mm and the particle size ratio is not more than 3. 3. Effect of low calorific value of fuel on production capacity The fuel used for the lime rotary kiln is mainly solid, liquid and gaseous fuels. The low calorific value of these fuels is different, and in order to ensure the good quality of the product, a certain calcination temperature must be required. When the low calorific value of the selected fuel is too small, the actual capacity cannot reach the rated capacity of the rotary kiln. When the low calorific value is high, the actual capacity will be greater than the rated capacity of the rotary kiln. Other factors affecting the capacity of the lime rotary kiln are: feed and discharge rates, limestone quality, operator experience, local temperatures, and other performance parameters associated with the rotary kiln.
