Rotary Kiln Can Be Directly Used In Cement Production Line
Total Articles: 263
Rotation Kiln can be directly calcining fine grade limestone at 10 ~ 50mm, hongxingly 30 to 40 percent limestone mining products 0 ~ 30mm fine grade limestone accounts for production, this part of the limestone can not use the other type of kiln. And with the raw materials of steel "concentrate" and sintering gradually replaced with lime limestone, fine grade limestone can not utilization. Construction of rotary kiln production line not only to take advantage of high-quality limestone mining resources, and meet the lime industry sustainable development policy.Material temperature rise to 750-800 ℃, the ignition loss decreased significantly, in combination with silica began to increase obviously, said calcium carbonate and solid phase reaction at the same time.Due to calcium carbonate decomposition reaction absorbs a great deal of heat, so the material heats up slowly.When the temperature rise to about 1100 ℃, calcium carbonate decomposition speed, reach maximum free lime, this area is called carbonate decomposition zone. High yield. Very suitable for large-scale active lime production line, and now the world has 2200 tons per dayof lime kiln production; abroad has built a lot of 150 to 300 tons of lime kiln, good running condition, but also for small and medium sized enterprises in the application of lime kiln.Scientific management, advanced processing technology and innovative manufacturing theory make Hongixng become the exporting base of cement mill, haydite kiln and famous grinding equipment in China. What Hongxing has done is for the clients and we believe that quality is the best way to develop market.Wet rotary kiln production will add water in the raw meal grinding, will be made water cut is 30% ~ 40% of raw slurry, it met the requirement of the homogenization of slurry from the kiln head mature, material feeding machine into stove kiln clinker cooling by the cooling machine, into clinker silo, raw coal after drying and grinding into a pulverized coal combustion supplies to clinker calcining heat required.As the material temperature rise, clay minerals content of dehydration, magnesium carbonate decomposition process.Due to dehydration and decomposition reaction ball materials gradually powder into powder material, and makes the material reaches a certain temperature, create conditions for the decomposition of calcium carbonate, therefore calls the area for the preheating zone.complete set of cement equipments: http://www.bestjawcrusher.com/news/242.html
