Rotary kiln equipment manufacturers is increasingly competitive, energy-efficient rotary kiln will emerge in response to the proper time and conditions, and there is a huge potential advantage of its technology and equipment. With the substantial rise of energy prices, the cost of production gives a lot of pressure tolime rotary kiln production enterprises, and it is facing great challenges of the survival and development of enterprises.

In addition, in recent years the state has gradually increased the supervision of environmental protection, so that the operation is even worse. Hence, it will become direct targets of the search for new fuels and energy-saving and environmental protection equipment for the rotary kiln manufacturer. Environmental protection measures of new technology active lime calcining rotary kiln are favored by more and more enterprises in the mining equipment industry. With the vertical preheater rotary kiln and vertical cooler energy-saving environmental friendly lime calcination process in production applications, breaking the traditional lime production pattern, has been recognized by many companies.

The technology equipment features of energy-efficient rotary kiln

First, the kiln inlet is equipped with vertical preheater, which making the flue gas heat of the rotary kiln inlet temperature about 900 degrees centigrade directly heat transfer to the limestone, and the temperature dropped to 200 degrees centigrade, and then through the discharge pipe into the dust collector, so that the effective recovery of the waste heat.

Second, the length to diameter ratio of the rotary kiln to reduce 14:15. The shorten of length not only reduced the heat of the surface of the rotary kiln loss to the surrounding, but also lessened the area of the equipment, meanwhile reduced the transmission powerof rotary kiln shell.

Thirdly, the whole production line of the rotary kiln has a high degree of automation. The PLC control system in the centralized control room is centralized controlling the production operation feeding, calcining and finished product transportation and the equipment operation monitoring, the adjustment, the alarm and so on.

Therefore, the application of energy-efficient and environment-friendly active lime rotary kiln technology has achieved the goal of energy saving, high efficiency and environmental protection, which is more advanced and worthy promotion of the rotary kiln calcination process in the active lime production.
