Portland Cement Rotary Calcining Kiln

Cement rotary kiln belongs to building materials equipment category, is kind of lime kiln. Rotary kiln according to the different materials can be divided into cement rotary kiln, metallurgical rotary kiln and lime rotary kiln. Cement kiln is mainly used for calcining cement clinker, dry production and wet production of cement kiln two categories. It is the main equipment of cement clinker dry and wet production line.
Cement rotary kiln structure is solid, stable operation, the kiln product quality is high, and can provide users with advanced high-efficiency vertical preheater, five cyclone preheater.
Cement rotary kiln structure includes the cylinder, transmission, care, wheel support device, kiln lining, kiln tail seal, kiln head and fuel devices and other components.
Cement rotary kiln classification: within the heating rotary kiln, outside the heating rotary kiln
1.Within the heating rotary kiln material and flame and flue gas in direct contact with the furnace can be achieved through the regulation of oxidation or reduction of the atmosphere, the cylinder wall masonry brick, head and tail cover lining for the high-strength wear-resistant castable, And between the cylinder for the flexible seal, can completely eliminate dust and leakage material, can take multi-file support, so that the length of the cylinder to 60 meters, the maximum temperature of up to 1600 ℃. Large output, applicable to the fuel for liquefied petroleum gas, natural gas, gas, fuel oil, coal, coal and so on.
2. Outside the heating rotary kiln material and flame and flue gas is not in direct contact with the heat source in the furnace and the cylinder between the heat-resistant steel cylinder wall heat to heat the material, the furnace lining for the refractory fiber, energy saving consumption. By the heating method and the cylinder material limit, the general cylinder length ≤ 15 meters, heating temperature ≤ 1200 ℃. Production is small, for heating methods: electric, gas, fuel, coal and so on.
During the operation of the cement rotary kiln, the parts will wear out over time, thus reducing the reliability of the operation of the equipment and even affecting the production of the rotary kiln, which must be resumed by means of maintenance. According to the size of maintenance work, sub-overhaul, repair and minor repair. The factory according to the usage of rotary kiln and maintenance of the preparation of large, medium and small repair plan. Focus on minor repair and medium repair.
