1. Introduction of Cement Making Machinery Cement rotary kilns are essential in the production of cement, where they are used to calcine clinker from limestone, clay, and other raw materials. Ensuring consistent quality requires maintaining a uniform temperature throughout the kiln's entry, mid-zone, and discharge. However, one of the main challenges is that temperature sensors must operate through flames or heavy smoke and dust, which can affect accuracy. To address this, our high-performance dual-wavelength sensors provide exceptional accuracy for cement kiln applications. These sensors can function effectively even when the target energy signal is diluted by up to 99% due to dust and smoke. For measurements through flames, the 1400 and 4400 Series are recommended, utilizing a narrow 3.8 micron filter to deliver reliable performance.
2. Advantages of Cement Making Machinery 1. The cement rotary kiln uses adjustable speed driving with high efficiency and low power consumption. 2. It has low fuel consumption per unit product and large capacity. 3. The mechanical performance is stable, with accurate speed control and easy regulation of the calcination temperature.
3. Structure of Cement Making Machinery 1. Support device: advanced shaft structure, automatic temperature measuring device, and electrical heating device. 2. Catch wheel: includes mechanical wheel and hydraulic pressure catch wheel. 3. Gears: single or double. The rotating speed is controlled by regulating motor, DC motor, or variable frequency and speed regulation motor. It is reliable, energy-saving, and efficient. 4. Cylinder tyre bolster: there are three types: fixed, zoom, and floating. Its structure is simple, replacement is convenient, and it won't damage the cylinder when replaced. 5. Sealing equipment: various options based on kiln models, including air cylinder edge sealing, spring edge sealing, graphite block sealing, and combinations. It adapts well to cylinder rotation and swing, offering excellent sealing performance. 6. Kiln head hood: available in stationary and flexible types.
4. Principle of Cement Making Machinery The kiln is a cylindrical vessel inclined slightly to the horizontal, rotating slowly around its axis. Raw material is fed into the upper end of the cylinder. As the kiln rotates, the material gradually moves down towards the lower end, undergoing some stirring and mixing. Hot gases pass along the kiln, usually in the opposite direction to the process material (counter-current). These gases may be generated externally or by a flame inside the kiln, projected from a burner-pipe. The fuel can be gas, oil, or pulverized coal.
