What are the technical parameters of the new lime shaft kiln
As the core equipment of modern lime production, the technical parameters of the new lime shaft kiln directly affect production efficiency and product quality. Taking Linyi Jinyong Kiln high-efficiency and environmentally friendly intelligent fossil ash vertical kiln as an example, its daily output covers 100-500 tons, with an effective volume of 98-735 cubic meters, an effective height of 20-26 meters for the kiln body, a cross-sectional diameter of 2.5-6 meters, and can be adapted to limestone with a particle size of 40-80 millimeters. The equipment adopts a DCS intelligent central control system, which realizes the automation of the entire process of feeding, unloading, and calcination. Only one operator is needed per shift to complete the operation.
In terms of technological highlights, this vertical kiln replaces traditional contactors with frequency converters, significantly reducing energy consumption and maintenance costs; Equipped with WINCC human-machine interface operating system, real-time monitoring and optimization of calcination process parameters. Its core performance indicators include: product heat consumption ≤ 4200KJ/kg, calcium oxide content>90%, activity>300ml, over burning rate ≤ 13%, and ash discharge temperature about 60 ℃ higher than ambient temperature. In addition, the kiln body is constructed with four layers of composite refractory materials, which have excellent insulation effects and a service life of 6-10 years for the refractory materials.
The new type of lime shaft kiln, with its advantages of high automation, low energy consumption, and long service life, is widely used in industries such as metallurgy, chemical engineering, and building materials, and has become an important choice for the transformation and upgrading of the lime production industry.
