CIC HMC developed large new dry process cement rotary kiln product with cement research and design institutes in Tianjin, Nanjing and Hefei by using domestic advanced technology, and the product can match 3000～10000t/d large new dry process cement production line. The company has a first-rate rotary kiln development, research and design team, perfect test and inspection means and excellent large rotary kiln manufacturing equipment and manufacturing technology, and has formed a complete technology and production system integrating rotary kiln design, manufacture, install and deb ing service.

1. Introduction
Rotary kiln is rotary forging kiln for short, which is one of building material equipment. It is divided into cement kiln, metallurgy and chemical kiln and lime kiln as per the different material treatment. Cement kiln is applied to carline cement clinker, which has two types,dry-type cement production kiln and wet-type cement production kiln. Metallurgy and chemical kiln is mainly used to magnetizing roast lean iron ore, oxidation roast the nickel chromium iron ore in the steel and iron plant. It is also used to roast bauxite chamotte in the refactory plant and chamotte, aluminium hydroxide in alumimium plant,crome ore in the Chemical plant. Lime kiln is use to roast active lime and soft-burned dolomite in steel plant and iron alloy plant.

2. Features
Rotary kiln is originally and widely applied to cement production, which is called the heart of cement plant. In the production of building material, Rotary kiln is used to calcine clay lime stone and cement clinker. In the production of refractory material, the kiln is used to calcine the material to extend of stable dimension, enough strength for machine-shaping.

Rotary kiln is one branch of rotary kiln system adopted in the steel and iron pellet with the extinguish design and structure. It is mainly composed of rotary parts, support parts, conveying parts, kiln head cover, kiln head and tail seal, combustion device. The ore, concentrate is sintered and calcined through rotary kiln. For example, aluminum hydroxide is calcined into alumina by the kiln in the aluminum production; Pellet ore for blast furnace is produced in the kiln in iron manufacturing. Iron ore is reduced directly through SL/RN process or Krupp process; Tin and lead can be refined through the kiln by chloridizing volatilization method .

In addition, there is over twenty years of history to burn the hazardous waste through rotary kiln in developed country with concern of environment. The hazardous waste can be not only reduced in quantity and risk level but also can be consumed as fuel to save energy.
