1. Introduction of Cement Making Machinery and Cement Production Line, Kiln Cement rotary kilns are essential in the production of cement, where they are used to calcine clinker from raw materials like limestone and clay. To ensure consistent quality, it is crucial to maintain a uniform temperature throughout the kiln at entry, mid-zone, and discharge. The challenge lies in accurately measuring temperature through flames or heavy smoke and dust. Therefore, sensor selection must consider design, wavelength, and alignment for reliable performance. Our high-performance dual-wavelength sensors offer unmatched accuracy and repeatability for cement kiln applications. These sensors can function effectively even when the target signal is diluted by up to 99% due to dust and smoke. For measurements through flames, the 1400 and 4400 Series are recommended. These single-wavelength sensors use a very narrow band 3.8-micron filter, providing excellent performance in such conditions.
2. Advantages of Cement Making Machinery and Cement Production Line, Kiln 1. Cement rotary kilns feature adjustable speed driving, offering high efficiency and low power consumption. 2. They have low fuel consumption per unit product and large capacity. 3. They provide stable mechanical performance and transmission, with accurate speed control and easy regulation of calcination temperature.
3. Structure of Cement Making Machinery and Cement Production Line, Kiln 1. Support device: advanced shaft structure, automatic temperature measuring device, and electrical heating device. 2. Catch wheel: includes mechanical and hydraulic pressure catch wheels. 3. Gears: single or double. 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: has three types: fixed, zoom, and floating. Its structure is simple, replacement is convenient, and it won't damage the cylinder when changed. 5. Sealing equipment: many types available according to kiln models, including air cylinder edge sealing, spring edge sealing, graphite block sealing, and combinations. It adapts to cylinder rotation and swing, and provides excellent sealing effect. 6. Kiln head hood: includes stationary type and flexible type.
4. Principle of Cement Making Machinery and Cement Production Line, Kiln The kiln is a cylindrical vessel slightly inclined 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, often in the opposite direction to the material flow (counter-current). These gases may be generated in an external furnace or by a flame inside the kiln. A flame is projected from a burner-pipe, acting like a large burner. Fuel can be gas, oil, or pulverized coal.
