Active Lime Rotary Kiln Production Line:

Kefan active lime rotary kiln production line clients' working site:

Active lime is metallurgy, chemical, papermaking and other eco-friendly raw materials. Till now, there are two methods lime making: one is vertical kiln technical, another one is rotary kiln technical. Vertical kiln method lime production with low capacity, demanding fuel, pollute environment. Rotary kiln lime system with kiln tail preheater and vertical cooler features: low energy consumption, high production capacity, suitable for different kinds of fuel, eco-friendly. Disadvantages: 1. Uneven limestone distribution in preheater, uneven heat transmission, low heat efficiency; 2. Low precalcining rate; 3. Vibration vertical cooler adopt many vibrating discharge device discharging at the same time. Effected by different vibrating frequency, it's difficult to realize unifrom discharging, at the same time, under the function of vibration force, block lime is easy to crush, decrease block rate. Besides, the more capacity required of production line, the bigger of the feeding chamber, the more technical difficult of the relative supporting structure and then effect big industrial production development. To deal with the status, kefan research new type active lime rotary kiln system technical. Has the following features: 1. Big production capacity, same quality preheating chamber, new type active lime system technical production line higher 25% production capacity; 2. Rotary kiln tail preheater heat excharge field heat force uniform distribution, high temperature waste gas and limestone heat exchange completely, high waste heat recovery rate, outlet system waste gas temperature low than 240 degree; 3. Higher 5-10% calcium carbonate decomposition rate in the rotary kiln than general production line; 4. Low investment, lower 20-30% than the same industrial.
