Wet rotary kiln for cement industry

Rotary kiln is widely used in the building materials, metallurgy, chemical, environmental protection and many other production industries, and extensive applies rotary liquid preparation of solid materials for mechanical, physical or chemical treatment. Rotary kiln application originated in cement production, 1824 British cement workers Aspen invented the intermittent operation of the soil kiln. We are the dryer manufacturer, and we come to introduce the main characteristics of the wet rotary kiln.
1. Wet rotary kiln calcination is characterized by: raw materials made of 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.
2. The production of raw materials in the mill by adding water, the raw material made of water for 30% to 40% of the slurry, the homogenization of the required slurry from the kiln feed machine into the kiln calcined mature material. The kiln clinker is cooled by the cooler, fed into the clinker, the raw coal is dried and the pulverized coal is pulverized and then burned to supply the heat required for the clinker calcination.
3. Rotary 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 speed up the evaporation of water.
4. 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.
5. 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, compared with shaft kiln and dry rotary kiln are high.
Rotary kiln technical performance and operation of the situation, to a large extent determine the quality of enterprise products, production and cost. In the field of rotary kiln applications, the largest number of is cement industry.
