The role of the device is out of clinker from the rotary kiln (1000-1300 ℃) cooled to (or less 200 ℃), while improving the quality of clinker grindability. [Performance Parameters: Φ1.5 × 15m-Φ3.3 × 40m [production capacity]: 2-36t / h [Applications]: widely used dolomite, kaolin, bauxite, refractory charge, cement, limestone, titanium-iron powder, bauxite ore, charcoal, coke, ore, alumina, magnesium oxide, zinc oxide, specialty materials and cement industries [applicable]: dolomite, kaolin, bauxite, refractory charge, cement, limestone, titanium iron, bauxite mine, activated carbon, coke, ore, alumina, magnesium oxide, zinc oxide, special cement heat exchange efficiency easy operation and maintenance 1, from out of the rotary kiln clinker (1000-1200 ℃) through the barrel Rotary drive materials and fully air heat exchange, so that the material was cooled to (200 ℃ or less), while improving the quality of clinker grindability, 2, the air-cooled material into the kiln after all, as the secondary circulating air improves the thermal efficiency of the kiln. Rapidly cooled single cylinder cooler operation rate is one of the important equipment kiln www.chinadjks.cn system, the role of the device is out of clinker from the rotary kiln (1000-1200 ℃) driven by the rotary cylinder material and fully air heat exchange, so that the material is cooled to (or less 200 ℃), while improving the quality of clinker grindability, the air-cooled material into the kiln after all, as the secondary circulating air, improve the thermal efficiency of the kiln. The device can be air-cooled material into the kiln after all, as the secondary circulating air, improve the thermal efficiency of the kiln, and it has a simple structure, operation rate, operation and maintenance is very convenient, for small cement plants.
