Great Wall Machinery has the domestic first-class cement rotary kiln development research and design team, the perfect cement rotary kiln test and testing means and sophisticated large-scale cement rotary kiln manufacturing equipment and manufacturing technology, which has formed a perfect cement rotary kiln design, manufacture, installation and Debugging services as one of the technology and production system.

1, no matter what the rotary kiln is, the technology has same principle, at present we only take wet rotary kiln technology to introduce and analysis. Nowadays, the Great Wall Machinery Co., Ltd. produces wet rotary kiln kiln body is usually relatively long (aspect ratio of 30 to 40), in order to increase the kiln heat transfer area, often hanging in the kiln hanging chain to accelerate the evaporation of water.

2, wet rotary kiln calcination characteristics are as follows: due to raw material is made from mud, so non-homogeneous raw materials adaptability, uniform raw material composition, process stability, firing high quality clinker, clinker strength level is high, Grinding process less dust, less kiln fly ash. But the wet production of evaporation of 30% to 40% of the slurry moisture, the need to consume more heat, energy consumption accounted for cement costs 1/2 to 1/3, more vertical kiln and dry rotary kiln are high. Wet production due to high heat consumption, energy consumption, and the production of water consumption, consumption of water resources, China has the wet cement production as a limit to eliminate kiln.

3, the current new dry rotary kiln is the market's most popular rotary kiln production equipment, the equipment calcination mechanism is advanced, roasting finished products excellent, and smooth operation, in the entire production line unit can carry strong, is the most reasonable investment Paragraph rotary kiln equipment, to avoid the advantages of wet rotary kiln, but also inherited its advantages, the production effect is remarkable.
