According to the exterior, the rotary kilns can be divided into diameter changes rotary kiln and size rotary kiln, into cement rotary kiln, ceramsite sand rotary kiln, soil rotary kiln and lime rotary kiln based on the purposes, into gas powered rotary kiln, coal-fired rotary kiln and mixed fuel rotary kiln depending on the different effects.
Rotary kiln calcining system produced by our company adopts internationally advanced hydraulic hatch wheel, high-precision plunger metering pump, high-precision low speed valve and contact mode graphite sealing device. To improve automatic degree, industrial television is set at kiln head for watching fire with analogical process flow fluorescent screen, and infrared scanner is adopted to reflect the calcining situation on computer directly. This new technology features strong visual effect, easy operation and reliable work. With stable heat engineering and high rotation rate, this kind of kiln has improved 10% rotation rate, 5%-10% capacity and lower 15% heat consumption, compared with other same model machine.
Rotary kiln for active lime are reliable combined scale sealing. The air leakage coefficient is less than 10% using composite refractory material, to reduce radiation loss. The followings include cement rotary kiln, limestone rotary kiln, and clinker rotary kiln.
1. Cement rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, green cement rotary kiln head hood and fuel device.
2. The limestone rotary kiln technical characteristics: advanced structure, low loss of vertical preheater can effectively improve the preheating effect, after the preheat limestone kiln decomposing rates up to 20-25%, and can directly use the 10-15mm fine-grained limestone.
3. Clinker rotary kiln is mainly used for chemical clinker calcining, the production of chemical sub-dry and wet kilns produce two types of chemical kilns. Rotary kiln is mainly used in chemical industry, metallurgy steel plant depleted iron ore magnetic roasting; chromium, nickel, iron ore roasting; refractory high alumina bauxite ore roasting plant and aluminum roasting clinker, aluminum hydroxide; chemical chromium ore roasting and chrome ore and other minerals.
In the mining production process, there are many types of rotary kilns. According to the firing methods of the kiln, it can be divided into direct fired rotary kiln and indirect fired rotary kiln; according to the processing methods, it can be divided into dry process rotary kiln, wet process rotary kiln and dry and wet types rotary kiln. In addition, Hongxing Machinery now has researched and developed a cylinder rotary kiln which has a cylinder drum, thus improving the production capacity of the machine and reducing the energy consumption. And what is more, the clay rotary kiln now also has wide application range in the cement making, building materials and clay manufacturing industry.
In cement production line, calcinating rotary kiln is mainly used for calcinating the cement clinker with high temperature. Therefore rotary kiln is the key equipment of cement production and known as the heart of the cement factory.
