The cement kiln is mainly used to calcine cement clinker; In the process of non-ferrous and ferrous metallurgy, such as iron, aluminium, copper, zinc, stannum, nickel, wolfram, chromium, etc., the rotary kiln can be used to sinter and roast ore, concentrate, intermedium, etc.; The lime kiln is mainly used to calcine limestones.

Rotary kiln is composed of shell, drive device, support and thrust roller, kiln lining, kiln inlet sealing, head hood and burning device etc.The rotary kiln firing system is equipment with technological innovation.Shell is the heated rotation part, which is welded by high quality carbon steel plate. It is mounted on supporting device through tyre. Mechanical or hydraulic thrust roller is equipped on supporting device. So it will control shell slide in axial direction. Driving device makes shell rotate through gear according to required revolving rate. Big size kiln has auxiliary drive to make shell rotate at low speed for kiln installation and maintenance request. In order to prevent cooling air into kiln and dust come out kiln, there is sealing device at kiln inlet and output end.

This system adopts the world advanced technology,such as the most advanced hydraulic block wheel device, a high measurement accuracy of measurement piston pump, high-precision control valve and contact-type graphite block sealing device.
